There  are  three  Principal  Points  worth  the  curious 
reader's  Observation  in  the  following  Treatise'. 

(I.)  A  description  of  the  NEW  KNOWLEDGE 
concerning  the  Sea  of  Carib,  alias  the  West  Indies 
Sea,  the  discovery  of  its  bottom  and  the  manner  in 
which  it  is  explored,  having  not  been  treated  of 
so  circumstantially,  as  far  as  I  know,  by  any  other 
author  before. 

(2.)  An  account  of  divers  voyages,  made  by  the 
command  of  scientific  curiosity,  for  the  discovery  of 
a  DEEP  HOLE  in  the  sea,  the  success  of  which 
proved  very  fortunate,  as  will  be  evident  from  the 
ensuing  Treatise. 

(3.)  A  succinct  account  of  that  monstrous  fish 
called  the  SHARK  and  the  manner  how  it  is  taken. 
The  whole  of  which  I  have  comprehended  in  sev- 
eral draughts  obtained  from  the  eminent  engraver 
D.  M.  Owen  and  others.  Fareivel.

Coon  after  the  voyage  of  Columbus,  the  Antilles  were  well  explored, 
first  by  the  Spanish  and  Portugese,  later  by  the  Dutch  and  English 
and  the  French.  Still  later,  geologists  studied  the  rock  formations  of 
islands  and  shores;  but  the  Caribbean  basin  remained  an  unknown 
territory. 

Few  oceanographic  investigations  were  made  in  the  area,  until 
it  became  a  favorite  haunt  for  the  Woods  Hole  Oceanographic  Insti- 
tution, when,  during  the  winter  months,  work  in  the  stormy  North 
Atlantic  is  not  practicable  for  our  small  vessels.  However,  one  must 
not  think  of  the  Caribbean  as  a  smooth  sea.  The  past  few  months 
saw  more  bad  weather  than  good,  with  days  on  which  the  northeast 
Trade  Winds  were  absent  and  it  blew  hard  from  the  southwest. 

Often  called  the  American  Mediterranean — which  includes  the 
Gulf  of  Mexico — the  Caribbean  Sea  yielded  many  of  its  secrets,  as 
Dr.  Officer  points  out  in  his  article. 

The  Associates  of  the  Institution  may  be  proud  that  their  fund 
was  used  to  support  in  part  the  work  in  the  Caribbean,  which  has 
added  to  our  store  of  knowledge  of  the  earth.

Exploring   The   Caribbean 


An  account  of  the  winter  cruise  of  the  R.V.  Atlantis 
and  the  R.V.  Caryn. 


ONE  of  the  more  fascinating  phases 
of  oceanographic  science  in  the 
recent  years  has  been  the  geophysical 
investigation  of  the  geological  struc- 
ture below  the  oceans.  Largely  through 
the  impetus  of  Professor  Maurice  Ew- 
ing,  Director  of  the  Lament  Geological 
Observatory  and  long  a  member  of  the 
staff  of  the  Woods  Hole  Oceanographic 
Institution,  the  work  in  this  field  has 
progressed  at  a  rapid  rate.  In  1947 
and  1948  the  first  seismic  measure- 
ments over  deep  water  were  made 
from  the  research  vessel  ATLANTIS. 
In  1949,  1950,  and  1951  many  seismic 
refraction  profiles  were  taken  from  the 
ATLANTIS  and  CARYN  over  the 
Western  Atlantic,  the  approaches  to 
the  North  American  continent,  to  tie 
in  with  Professor  Ewing  and  his  col- 
laborators earlier  work  over  the  conti- 
nental shelf,  and  to  a  smaller  degree 
in  the  Caribbean.  These  profiles  led  to 
a  basic  understanding  of  the  geologic 
structure  of  the  oceanic  areas  and  how 
they  graded  into  the  continents.  From 


1952  on,  the  work  has  continued  from 
our  ships  and  others  extending  the 
coverage  over  the  eastern  and  Southern 
Atlantic,  the  Mediterranean  and  Nor- 
wegian Seas,  and  the  Gulf  of  Mexico. 

Gaps    in    knowledge 

At  the  time  of  the  present  cruise 
one  of  the  biggest  gaps  in  geologic 
knowledge  was  that  of  the  structure 
of  the  Caribbean,  the  island  arc  of  the 
Antilles,  and  the  associated  Puerto  Rico 
trench  (the  deepest  part  of  the  Atlan 
t  ic  Ocean ) .  It  also  turns  out  that  an 
understanding  of  such  an  area  is  most 
important  to  the  basic  questions  in 
geology,  for  these  are  the  active  areas 
of  today;  and  much  of  the  land  geology 
that  we  walk  across  points  to  the  hypo- 
thesis that  once  they  were  similar  in 
structure. 

The  geophysical  equipment  on  both 
the  ATLANTIS  and  CARYN  was  such 
that  measurements  were  obtained  of 
the  topography  of  the  ocean  floor  from 


p/ecision  echo  sounder  recordings,* 
the  upper  portion  of  the  sedimentary 
column  from  seismic  reflection  profiles, 
<md  the  total  sedimentary  column  and 
underlying  crystalline  rocks  down  to 
the  substrata  from  seismic  refraction 
profiles.  In  addition  measurements  of 
sound  transmission  in  the  ocean  were 
obtained  over  the  differing  water  and 
bottom  types  encountered.  A  seismic 
profile  is  made  by  one  ship,  say  the 
ATLANTIS,  heaving  to  and  preparing 
to  listen  and  record  from  sensing  ele- 
ments in  the  water.  The  second  ship, 
the  CARYN,  then  proceeds  away  from 
the  ATLANTIS  on  a  prescribed  course 
firing  explosives,  gradually  increasing 
in  size  from  one  half  pounds  of  TNT 
to  350  pounds,  out  to  a  distance  of 
40  to  50  nautical  miles.  The  CARYN 
then  heaves  to  and  prepares  to  listen, 
and  the  ATLANTIS  gets  underway 
firing  charges  up  to  her  to  complete 
the  profile. 

Some   Statistics 

Twenty-three  tons  of  explosives 
were  used  to  fire  about  2,000  shots  in 
the  completion  of  47  seismic  refraction 
and  reflection  profiles.  The  ships  each 
sailed  more  than  4,500  miles,  so  that 
9,000  miles  of  bottom  records  were 
charted  by  echo-sounding.  The  scien- 
tific data  obtained  during  the  cruise 
weighed  approximately  500  pounds 
and  the  laboratory  analysis  of  these 
records  will  take  at  least  six  months. 

Those  primarily  responsible  for  the 
geophysical  work  were  Mr.  Richard

The  geophysical  equipment  on  the 
ATLANTIS  came  from  the  Woods 
Hole  Oceanographic  Institution  and 
that  on  the  CARYN  from  Lamonc 
Geological  Observatory  and  Woods 
Hole  Oceanographic  Institution.  Other 
programs  that  were  carried  out  con. 
currently  were  one  in  chemical  ocean- 
ography by  Dr.  Francis  Richards  and 
Mr.  Ralph  Vaccaro,  joined  for  a  por- 
tion of  the  trip  by  Mr.  Sayed  Wardani 
from  Scripps  Institution  of  Ocean- 
ography; one  in  marine  biology  by  Dr. 
John  Ryther,  and  one  in  a  combination 
acoustical  and  optical  investigation  of 
the  deep  scattering  layer  by  Messrs. 
Johnson  and  David  Owen.*  Also 
aboard  engaged  in  one  or  another  of 
the  phases  of  investigation  for  a  por- 
tion or  all  of  the  cruise  were  Messrs. 
Alvin  Bradshaw,  William  Dunkle, 
Gerrit  Duys,  Jan  Hahn,  William  Hud- 
son from  Bell  Telephone  Laboratories, 
William  Moss,  and  Milton  Rutstein. 

The  ships  left  Woods  Hole  on  the 
nineteenth  of  January,  stopped  at  Ber- 
muda, and  arrived  in  St.  Thomas  on 
the  second  of  February,  after  an  ex- 
tremely stormy  passage.  The  work  in 
the  Caribbean  area  was  along  tracks 
from  St.  Thomas  south  to  the  coast  of 
Venezuela  and  up  to  Martinique,  from 
Martinique  out  to  the  Atlantic  and 
back  to  Trinidad,  from  Trinidad  north

Was  the  cruize  a  success?  We  defi- 
nitely think  so.  We  obtained  almost 
twice  as  much  geophysical  information 
as  we  had  planned,  and  we  feel  that 
we  have  the  data  in  hand  to  determine 
the  geologic  structure  and  variations 
in  geologic  structure  over  the  various 
features  of  the  Caribbean  area. 

The  cruise  was  supported  in  part 
by  the  Associates  through  payments 
for  most  of  the  operating  expenses  of 
the  CARYN.  I  wish  to  express  my

thanks  to  them  for  this  support. 

It  was  a  blow  to  all  of  us  to  learn 
on  returning  to  Woods  Hole  that  one 
of  cur  group,  Mr.  Gerrit  Duys,  had 
died  cf  a  heart  attack.  Mr.  Duys  had 
become  sick  during  the  cruise  from  a 
virus  infection.  He  was  left  at  Bar- 
bados and  upon  recovering  returned  to 
Woods  Hole.  I  know  that  the  other 
members  of  the  scientific  party  and  the 
officers  and  crew  of  the  ships  join  me 
here  in  expressing  their  sympathies  at 
the  loss  of  such  a  fine  person.  He  was 
one  of  the  most  generous  and  kind 
hearted  persons  that  I  have  known.

I  ATE  in  February  the  Executive 
•*  Committee  and  the  Corporate  Com- 
mittee held  a  joint  meeting  at  the  New 
York  Yacht  Club,  to  discuss  the  growth 
and  the  activities  of  the  Associates 
Program. 

Admiral  Smith  explained  current 
activities  at  the  Institution  and  made 
special  mention  of  the  fact  that  the 
cruise  of  the  R.V.  ATLANTIS  and 
R.V.  CARYN  in  the  Caribbean  Sea 
was  financed  in  part  by  Associate  funds. 


Other  uses  to  which  your  contribu- 
tions are  being  applied  were  men- 
tioned by  President  Swope.  $4,300 
provides  for  the  salary  of  Miss  Beatrice 
Stern  to  operate  a  spectroscope  in  the 
tracing  of  "tagged  water"  (see  Oceanus 
III,  1  ) .  Also  supported  are  six  lectures 
to  be  given  this  summer  by  Dr.  Gifford 
C  Ewing  of  the  Scripps  Institution  of 
Oceanography.  Dr.  Ewing  will  also 
act  as  consultant  oceanographer  during 
the  summer  months.  Further  funds  are 
applied  to  basic  research,  a  fellowship 
and  the  making  of  a  motion  picture 
on  oceanography. 

A  report  on  the  vigorous  activities 
of  the  Committee  on  Corporate  Associ- 


ates was  presented  by  Chairman  Noel 
B.  McLean.  Mr.  McLean  noted  that 
about  $3,500.  was  received  in  addition 
to  $16,000  obtained  from  member 
corporations  and  companies. 

Mr.  M.  C.  Gale  reported  that  he  had 
explored  the  need  and  cost  of  a  game 
fish  library  to  be  established  at  the 
Institution.  It  was  thought  that  such 
a  library  would  be  useful  but  not  es- 
sential, and  the  proposal  was  tabled.  It 
was  suggested  that  an  exploratory 
article  might  appear  in  Oceanus  asking 
for  an  expression  by  the  individual 
Associates. 

Finally,  it  was  reported,  that  a  plan 
to  be  known  as  the  Woods  Hole 
Oceanographic  Associate  Fellowship, 
will  provide  funds  to  permit  an  out- 
standing young  person  to  obtain  a  doc- 
torate degree  in  the  earth  sciences  and, 
it  is  hoped,  a  career  in  oceanography 
at  the  Institution.  One  fellowship  will 
be  awarded  this  year,  two  the  next  year, 
and  three  yearly  thereafter.  "Thus", 
Admiral  Smith  concluded,  "Ocean- 
ography and  the  Institution  will  be 
nourished  with  new  talent  by  the  use 
of  funds  made  possible  by  the 
Associates."

THE  CARIACO  TRENCH 


>y   Francis   A.    Richards 


A  basin  of  stagnant  water  was  found  in  the  Caribbean  Sea  and  proves 

of  great  aid  in  studying  the  nutrient  cycles  in  the  sea  and 

the  formation  of  petroleum  in  sedimentary  basins. 


THE  Cariaco  Trench*  is  a  basin  just 
north  of  Venezuela,  in  the  south- 
eastern Caribbean.  About  780  fathoms 
at  its  greatest  depth,  the  trench  is  shut 
off  from  the  rest  of  the  sea  by  a  sill 
which  permits  no  ocean  water  to  enter 
from  depths  greater  than  about  80 
fathoms. 

Before  any  observations  were  made 
there,  a  study  of  bottom  charts  showed 
that  the  configuration  of  the  trench 
imd  the  isolation  of  its  deeper  water 
made  it  interesting,  since  it  seemed 
possible  that  the  trench  might  contain 
stagnant  water  and  thus  afford  a  place 
where  biochemical  processes  were  tak- 
ing place  in  an  essentially  static  part 
of  the  ocean,  thus  simplifying  investi- 
gations by  eliminating  the  time-motion 
factors  which  are  so  difficult  to  evalu- 
ate in  the  open  ocean. 

First    Visit 

The  trench  was  first  visited  by  AT- 
LANTIS in  December  1954,  at  which 
time  L.  V.  Worthington  found  that 
the  water  was  anaerobic — free  of  dis- 
solved oxygen — from  about  1,600  feet 
down.  This  showed  that  the  place  was 
static — at  least  much  more  so  than  any 
known  part  of  the  open  ocean  where 
dissolved  oxygen  is  present  at  all 
depths.  At  that  time,  it  was  obvious 
from  the  odor  of  the  water  samples 
that  hydrogen  sulfide  was  present,  al- 
though the  ship  was  not  equipped  to 
determine  the  substance  chemically. 

*  See  chart  on   Page  4. 


Similar  situations  are  known  to  exist 
in  the  Black  Sea,  in  threshold  fjords 
and  in  certain  semi-enclosed  basins,  all 
of  which  receive  considerable  land 
drainage.  This  drainage  supplies  an 
abundance  of  nutrients,  principally 
nitrate  and  phosphate,  which  so  ferti- 
lize the  upper  layers  that  a  greater  than 
usual  amount  of  organic  matter  is  pro- 
duced by  the  growth  of  plants — the 
microscopic  phytoplankton.  Upon 
sinking  into  the  stagnant  layers,  this 
organic  matter  decomposes,  using  oxy- 
gen until  all  the  oxygen  is  gone.  After 
that,  bacterial  decomposition  continues, 
but  the  oxygen  is  supplied  by  the  sul- 
fate  in  sea  water,  thereby  reducing  the 
sulfate  to  sulfide.  During  this  decom- 
position the  organic  compounds  of 
nitrogen  and  phosphorus  which  were 
bound  in  the  bodies  of  the  organisms 
during  their  growth  in  the  upper  layers, 
are  again  released  to  the  water  in  solu- 
tion as  inorganic  compounds  of  nitro- 
gen and  phosphorus. 

In  the  deep  water  of  the  open  ocean, 
the  supply  of  organic  material  from 
the  surface  is  so  slow,  and  is  so  bal- 
anced by  fresh  supplies  of  waters  that 
were  at  one  time  aerated  in  the  surface 
layers,  that  anaerobic  conditions  do  not 
arise.  The  ocean  circulation  also  prob 
ably  brings  about  a  slow  return  of  in- 
organic nutrients  to  the  surface  layers. 
In  anaerobic  parts  of  the  sea,  such  ex- 
changes either  do  not  occur  or  are  very 
slew,  and  processes  of  deoxygenation, 


sulfide  formation  and  the  regeneration 
of  nutrient  salts  are  uninterrupted. 

The  trench  differs  from  the  other 
known  anaerobic  parts  of  the  sea,  be- 
cause it  receives  little  land  drainage, 
and  its  upper  layers,  almost  completely 
open  to  the  sea,  are  far  from  semi- 
enclosed.  Therefore,  the  manner  in 
which  nutrient  materials  are  brought 
into  this  marine  environment  are  quite 
different  and  give  us  a  new  field  for 
study. 

Exciting    Discovery 

The  fact  that  the  Cariaco  Trench  is 
anaerobic  was  a  rather  exciting  dis- 
covery. Woods  Hole  scientists  were 
anxious  for  additional  information,  and 
a  return  visit  was  made  in  February 
of  this  year.  The  lower  laboratory  of 
ATLANTIS  was  equipped  for  the 
determination,  at  sea,  of  dissolved  oxy- 
gen, hydrogen  sulfide,  nitrate,  nitrite, 
ammonia,  phosphates,  and  other  chem- 
ical properties  of  the  water,  Mr.  Ralph 
F  Vaccaro,  bacteriologist,  who  studied 
the  nitrogen  compounds,  Dr.  John  H. 
Ilyther,  microbiologist,  who  conducted 


experiments  to  determine  the  produc- 
tivity of  the  plankton  population,  and 
the  writer,  who  did  other  chemical  and 
hydrcgraphic  work,  were  aboard.  Mr. 
Sayed  Ali  el  Wardani,  of  Scripps  Insti- 
tution of  Oceanography,  came  on  board 
at  St.  Thomas,  Virgin  Islands,  and  did 
the  determinations  of  sulfides  and  hy- 
drogen ion  concentrations,  subjects  in 
which  he  has  specialized  at  Scripps. 
Water  samples  were  taken  from  the 
surface  to  the  bottom  at  several  places 
in  the  trench,  and  core  samples  of  the 
bottom  were  obtained.  The  work  was 
carried  on  in  conjunction  with  Dr.  C. 
B.  Officer's  geophysical  cruise  which  is 
described  elsewhere  in  this  issue. 

Only  preliminary  studies  have  been 
made  of  the  data  obtained  on  the 
cruise,  but  they  should  prove  helpful 
in  understanding  the  nitrogen  and 
phosphorus  nutrient  cycles  in  the  sea, 
the  microbiology  of  an  anaerobic  en- 
vironment, the  circulation  of  the 
trench,  and  sedimentation  processes 
which  may  be  of  application  to  studies 
of  the  formation  of  petroleum. 


GIFTS  AND  GRANTS 


With  pleasure  we  report  that  the 
following  gifts  and  grants  have  been 
received : 

Alfred   P.   Sloane   Foundation, 

Inc.  .  $5,000. 

Shell  Company  Foundation  $  500. 

Both  grants  have  been  made  to  con- 
tribute toward  the  cost  of  making  a 
motion  picture  on  oceanography,  the 
purpose  of  which  is  to  inform  the  pub- 
lic and  especially  prospective  college 
students  about  the  science  of  the  sea. 
The  final  draft  of  the  motion  picture 
script  is  presently  in  preparation. 


In  addition  to  the  above,  the  Insti- 
tution received  a  check  for  $5,000 
from  Mr.  N.  B.  McLean,  President  of 
the  Edo  Corporation,  College  Point, 
New  York. 

Although  the  annual  Corporate  As- 
sociates contribution  is  $1,000,  Mr. 
McLean  sent  his  larger  contribution 
with  the  statement:  ''We  sincerely  be- 
lt c-ve  that  the  basic  research  being  done 
at  Woods  Hole  contributes  immeasur- 
ably to  the  industry  in  which  ive  are 
interested  and  also  to  the  welfare  and 
support  of  our  country".

SHARKS 


No/  c/j"  of/672  encountered  at  sea  as  they  arc  in  popular  literature, 
much  remains  to  he  learned  of  their  behavior. 


A  problem  that  has  always  faced  the 
^*- naturalist  who  is  interested  in  the 
ocean's  larger  creatures,  is  that  he  rare- 
ly can  spend  enough  of  his  time  at  sea 
to  accumulate  a  significant  number  of 
observations.  The  whales,  porpoises, 
sec  turtles,  sharks  and  large  fishes  are 
less  often  encountered  than  one  might 
suppose  from  reading  much  of  the 
literature  of  the  sea.  At  the  Institution, 
those  who  see  such  animals  most  often 
are  the  officers  and  crews  of  our  vessels 


whose  job  may  keep  them  at  sea  almost 
continually.  It  is  in  this  field  that  these 
men  can  best  contribute  directly  to  our 
scientific  endeavors. 

Illustrative  of  this  is  the  shark- 
fijhing  program  in  which  the  ATLAN- 
TIS has  been  engaged  during  the  last 
couple  of  years.  With  some  extra  effort 
in  examining  specimens  and  keeping 
careful  records,  what  was  formerly 
sport  or  the  seaman's  traditional  ven- 
geance, has  been  turned  into  science. 


11 


During  the  last  nine  months,  led  by 
Captain  Scott  Bray,  First  Mate  A.  D. 
Colburn,  Boatswain  Carl  Speight,  and 
former  Radioman  Thomas  Lyon,  the 
ATLANTIS  has  preserved  data  from 
45  sharks. 

Whenever  the  ATLANTIS  is  hove 
to  for  coring,  hydrographic  stations,  or 
is  the  "silent  ship"  in  an  underwater 
sound  exercise,  a  couple  of  stout  lines 
with  chain-leadered  hooks  are  thrown 
over,  bearing  table  scraps  provided  by 
amiable  Steward  Joe  Lambert.  Gen- 
erally the  cry  of  "Shark!"  even  brings 
up  "the  watch  below".  The  hooked 
shark  is  dispatched  by  a  volley  of  rifle 
fire  by  the  ATLANTIS'  gunbugs.  The 
moribund  shark  is  hauled  aboard, 
whereupon  it  is  measured  and  cut  open. 
Sharks  are  hard  to  kill  and  more  than 
once  the  fishermen  have  had  to  take 
to  the  rigging  to  avoid  the  snapping 
jaws  and  flailing  tail  of  a  supposedly 
deceased  specimen. 

The  open  ocean  shark,  widespread  in 
the  warmer  parts  of  the  Atlantic  and 
common  in  the  Caribbean,  is  the  white- 
tip  shark  about  which,  in  spite  of  its 
commonness,  little  is  known.  It  is  a 


brownish  shark  easily  identified  by  its 
rounded  dorsal  fin,  the  tip  of  which  is 
white.  This  shark  is  usually  the  nucleus 
cf  an  interesting  aggregation  of  other 
animals.  The  silver  and  black-barred 
shark  pilot*  often  accompanies  it,  but, 
contrary  to  legend,  generally  swims 
above  and  behind  the  shark  rather  than 
in  the  lead.  One  or  several  remoras,  or 
shark-suckers,  are  almost  always  adher- 
ent to  the  white-tip,  and  so  persistent 
is  their  grip  that  they  are  hauled  aboard 
with  the  shark.  Sometimes  a  small 
school  of  the  beautiful  blue-green- 
yellow  dolphin  fish  swims  with  the 
white-tip.  These  are  often  caught  as 
they  swim  near  the  hooked  shark. 

ATLANTIS  records  have  shown 
much  about  the  white-tip's  food,  breed- 
ing habits,  and  behavior.  One  of  the 
more  interesting  points  revealed  is  the 
tendency  for  large  areas  to  contain  pre- 
dominantly male  white-tips,  while  the 
females  are  predominant  in  another 
aiea.  This  phenomenon  is  little  under- 
stood, but  continued  efforts  on  the  part 
of  the  ships'  crews  should  lead  us  to 
the  answer  to  this  question  and  many 
others  about  some  of  the  ocean's  bigger 
animals.

Third    Annual    Associates    Dinner 

The  Third  Annual  Associates  Dinner  took  place  on  April  19  at 
the  New  York  Yacht  Club.  The  140  Associates  and  guests  present, 
heard  an  address  by  Mr.  Robert  H.  Simpson,  hurricane  specialist  of 
the  U.S.  Weather  Bureau,  and  saw  a  motion  picture  of  Hurricane 
"Carol's"  havoc  at  Woods  Hole.  The  picture  was  made  last  fall  from 
the  Institution's  windows  by  oceanographer  Wm.  S.  von  Arx.

SPRING   CRUISE  OF  THE   BEAR 

by    J.    B.    Hcrsey 

From  the  deepest  spot  in  the  Atlantic  Ocean  to  the  Blake  Plateau, 
the  Bear  had  some  rough  going. 


THE    research    vessel    Bear,    a    103 
foot  motor  vessel,  departed  Woods 
Hole  on  the  first  of  February  for  St. 
Thomas,   V.  I-    She   was  held    in   Ber- 
muda for  several  days  by  very  rough 
seas,     eventually     reaching     Charlotte 
Amalie  about  the  middle  of  the  month. 
With    the   aid    of   our   new    precision 
echo-sounder  recorders  we  made  sur- 
veys of  the  Caribbean  approach  to  the 
Anegada  Passage  in  the  Virgin  Island 
area  and  made  various  studies  of  sound 
scattering  including  lower  ings  of  the 
acoustical    view    finder    camera     ( see 
Oceanus    III,    2 )     and    other    purely 
acoustical     observations.      Continuing 
this  work   off   the   southern   coast   of 
Puerto  Rico   we   sailed    to   Mayaguez, 
a    seaport    on    the    western    coast    of 
Puerto  Rico. 

There,  the  scientific  party  visited 
the  Department  of  Biology  of  the 
University  of  Puerto  Rico  and  were 
treated  to  a  very  pleasant  tour  of  the 
newly  established  marine  biological 
station  and  zoological  garden,  being 
set  up  on  an  island  off  the  southern 
coast  by  Dr.  Juan  Rivero,  as  part  of 
the  University's  instructional  and  re- 
search program.  Dr-  Rivero  not  only 
welcomed  us  most  cordially  to  the 
University  but  was  most  helpful  in 
solving  some  logistic  problems  that 
would  otherwise  have  delayed  our 
work  considerably. 

Departing  Mayaguez  on  February 
28th,  we  kept  rendezvous  with  the 
R/V  Vema  of  the  Lament  Geological 
Observatory  at  a  point  northwest  of 
Puerto  Rico  near  the  deepest  part  of 
the  North  Atlantic,  the  Puerto  Rico 
Trench.  The  Vema  was  equipped  with 


a  precision  echo  sounder  of  Lamont's 
design  and  together  we  were  able  to 
make  tracks  of  parallel  soundings  over 
the  deep  ocean  just  east  of  the  Bahama 
reefs,  from  the  Trench  to  the  North- 
east Providence  Channel  of  the  Baha- 
mas. The  Puerto  Rico  Trench  has  a 
flat  bottom  (see  page  4)  over  which 
both  ships  passed  on  somewhat  differ- 
ent tracks.  We  were  gratified  to  find 
that  soundings  taken  by  the  two  ships 
agreed  within  two  or  three  fathoms  on 
the  flat  bottom,  at  a  depth  consider- 
ably over  four  miles. 

A  number  of  seismic  refraction  pro- 
files   were    made    on    the    continental 
shelf  and   the  Blake  Plateau  between 
the  Bahamas  and  Charleton,  S.  C,  con- 
tinuing  a    study   commenced    by    the 
Atlantis  and  the  Bear  last  year.    Dur- 
ing March,  sailing  out  of  Charleston, 
the  Bear  under  the  leadership  of  Mr. 
Ralph  Wyrick  of  this  Institution,  and 
the   Vema   under   Dr.   John   Nafe   of 
Lament,  continued  the  seismic  studies 
in  this  area  until  the  end  of  the  month 
when  the  Vema  left  us  and  the  Atlan- 
tis joined  in  the  work,  after  complet- 
ing   her    Caribbean    work    under    Dr. 
Officer.  The  special  target  of  the  work 
in  March  had  been  to  study  the  geo- 
logic structural  relations  between   the 
2600  fathoms  deep  ocean  to  the  east, 
the    Blake   Plateau,    which    rises    to   a 
depth  of  200-700  fathoms  in  the  mid- 
dle and  the  less  than  100  fathoms  deep 
continental  shelf  on   the  western  side 
of  the  area-  During  April,  with  Messrs. 
Henry  Johnson  and  Richard  Edwards 
on  Atlantis  and  the  writer  on  the  Bear, 
we   studied    the   structures   where   the 
Blake  Plateau  narrows  down  between 


14 


the  shelf  and  a  topographic  ridge 
which  extends  outward  from  the  con- 
tinent into  the  adjacent  ocean  basin. 
In  one  month,  we  could  hope  to  do 
little  more  than  draw  a  rough  outline 
of  the  underlying  structure.  A  prelim- 
inary examination  of  the  results  tells 
us  that  the  topographic  ridge  is  indeed 
i1  surface  expression  of  a  large  fold  in- 
volving the  whole  outer  crust  of  the 
earth  here.  We  believe  that  further 
study  of  our  present  data  will  tell  us  at 
least  part  of  the  relationship  between 
this  folded  structure  and  the  deep 
ocean  basin,  the  North  America  basin, 
to  the  east. 

In  addition  to  the  seismic  obser- 
vations, the  Atlantis  obtained  a  few 
cores  of  bottom  sediment  while  the 
Bear  made  more  lowerings  of  the 
acoustical  view  finder  camera.  The 
weather,  which  had  been  remarkably 
good  until  the  middle  of  April,  be- 
came about  equally  poor  for  the  re- 
mainder of  the  cruise-  As  a  result  the 
last  part  of  the  planned  program  had 
to  be  abandoned.  After  nine  days  of 
nearly  constant  seas  of  about  twelve 
feet  high,  we  were  relieved  to  cross 
the  Gulf  Stream  and  find  much  calmer 
seas  for  our  return  to  Woods  Hole 
early  in  May. 


Oceanography? 


Oceanology? 


servations  there  was  a  sign  on  Dean 
Bumpus'  door  stating:  Laboratory  of 
Oceanology. 

This  is  all  very  well,  but  we  have 
heard  many  people  mispronounce 
oceanographic  in  various  ways  and  we 
fear  to  think  what  they  might  do  to: 
Woods  Hole  Oceanological  Institution, 
if  this  ever  came  to  pass. 

The  difficulty  with  this  science  is 
that  it  is  no  science  at  all,  but  rather 
a  series  of  sciences.  Many  people  still 
appear  to  think  that  an  oceanographer 
is  someone  who  catches  and  looks 
at  strange  fishes,  not  realizing  that 
physicist,  chemist,  biologist,  geologist, 
meteorologist,  geophysicist  and  almost 
every  other  'ist'  but  the  astrologist 
have  a  part  in  the  study  of  the  ocean. 
Finally,  this  study  of  the  sea  is  also 
but  ONE  of  the  earth  sciences  while 
at  the  same  time  containing  all  of  the 
disciples  who  study  the  earth  sciences. 

By  this  time  we  are  almost — but 
not  quite — as  confused  as  our  readers 
and  can  only  suggest  that  you  peruse 
this  once  more  carefully  and  you  will 
know  more  about  oceanography  or 
oceanology  than  we  can  hope  to  tell 
you  for  some  time  to  come. 

In  the  next  issue  of  DEEP  SEA 
RESEARCH,  Dr.  J.  N.  Carruthers 
of  the  British  National  Institute  of 
Oceanography  will  refute  Commander 
Hall  and  his  use  of  the  term 
oceanology. 


JJST  about   when   oceanography  has 
become    rather    widely    known,    up 
comes  Commander   C.   P.   N.   Hall, 
R.N.,  to  suggest  in  the  journal  DEEP 
SEA    RESEARCH,    that    we   use    the 
word   oceanology   since   this   describes 
the  science  of  the  ocean  or  ocean  study 
while  oceanography  means  description 
of  the  ocean. 

Some  European  scientists  jumped 
into  the  fray  and  have  started  to  use 
oceanology  and  before  you  could  say 
geomagnetic  electrokineto graphic  ob- 


Whenever in  or  near  Woods  Hole, 
Associates  are  cordially  invited  to  at- 
tend our  weekly  staff  meetings,  held 
Monday  evenings  at  8:00  p.m.  in  the 
Conference  Room  of  the  Laboratory 
of  Oceanography.  At  these  meetings 
one  of  our  staff  members  or  a  visiting 
scientist  gives  an  informal  account  of 
the  latest  developments  in  his  work 
or  field.

CURRENTS  AND  TIDES 


Dr.  M.  S.  Longuet-Higgins,  of  the 
British  National  Institute  of  Ocean- 
ography, visited  in  April  and  lectured 
on  "Analyzing  the  sea  surface." 


Staff  members  on  the  air.  On  June 
21  from  9:30  to  10:00  DST,  and  on 
June  23  from  8:30  to  9:00  DST,  you 
will  be  able  to  hear  a  shoal  of  staff 
members  discoursing  on  NBC's  pro- 
gram "New  England,  a  Regional  Sur- 
vey". The  interviews,  recorded  last 
winter,  are  part  of  Program  number  7 
of  the  NBC  series  which  will  start  on 
May  3- 


On  a  recent  visit  to  U.S.  Coast 
Guard  Headquarters  in  Washington, 
Admiral  Smith  demonstrated  a  model 
of  the  new  Air  Sea  Rescue  buoy  de- 
veloped for  the  Navy  by  our  Messrs. 
Harold  E.  Sawyer,  F.  deW.  Pingree  and 
Robert  G.  Walden.  The  exhibit  model 
is  on  loan  to  the  Office  of  Naval  Re- 
search and  was  designed  by  Mr.  G.  G. 
Pasley. 


Plans  to  invade  a  "foreign  ocean", 
are  being  made  by  Mr.  Henry  C. 
Stetson,  submarine  geologist  on  our 
staff.  Mr.  Stetson  plans  to  take  AT- 
LANTIS to  the  South  Pacific  next  fall. 
This  would  be  the  first  time  the  ship 
has  left  the  Atlantic  Ocean  and  ad- 
jacent seas. 


Many  grade  and  high  schools  featur- 
ed the  oceans  in  their  science  programs 
this  spring.  A  flow  of  material  was 
sent  in  reply  to  dozens  of  letters  from 
many  states.  The  largest  single  group 
of  letters  came  from  Mitchelville,  Iowa, 
which  we  have  not  been  able  to  find 
on  a  map.  Such  requests  are  suggestive 
of  a  growing  interest  in  oceanography. 


A  record  of  whale  noises,  made  by 
our  ketophonist  Mr.  W.  E.  Schevill, 
was  sent  to  the  Gilbert  School  in  Win- 
sted,  Conn.,  to  be  used  during  a  liter- 
ary discussion  of  Moby  Dick  and  other 
whaling  books. 


Seventy-three  newspaper  feature 
writers,  editors  and  TV  men  from  the 
West  and  mid-West  visited  the  Insti- 
tution in  April  under  the  auspices  of 
American  Airlines.  They  made  a  cruise 
on  the  CARYN  from  New  Bedford  to 
Woods  Hole  and  were  given  a  guided 
tour  of  the  laboratories.  During  the 
cruise  they  witnessed  the  rescue  of  our 
overeager  Public  Information  Officer, 
who  followed  a  plankton  net  over 
the  stern. 


"The  Continental  Shelf",  is  the  title 
of  an  article  by  submarine  geologist 
Henry  C.  Stetson,  in  the  March  issue 
of  "Scientific  American."
