PREFACE 
UNITED STATES BOARD ON GEOGRAPHIC NAMES 

The United States Board on Geographic Names (BGN) is the official United States body created in 1890 to provide 
for uniform usage of geographic names throughout the Federal Government. Established in its present form by a 
Public Law enacted in 1947, BGN operates through several committees to standardize names of geographic features in 
the United States, foreign areas, Antarctica, undersea areas, and extraterrestrial bodies. According to the law. the 
Board shares its responsibility with the Secretary of the Interior. In the exercise of this responsibility, the Secretary 
approves names recommended by BGN, appoints members to certain committees, and ratifies principles and 
procedures. Members of the Board represent various Federal departments and agencies, and they serve for two-year 
terms. 

Essential to the Board's function of standardizing names is the promulgation of names information. 
Traditionally, names of geographic features outside the United States have been published in a series of BGN gazet- 
teers and the needs of a wide range of users — both within the Federal Government and elsewhere — have been well 
served by these publications. The present gazetteer is one of a new series of place-name documents that is quite 
similar to the earlier BGN gazetteers. Features of the gazetteer are explained in the introduction. 

The responsibility for producing and distributing the gazetteers has been assigned to the Defense Mapping 
Agency as part of its overall mission of supporting foreign-area scientific studies for the Federal Government. The 
production of gazetteers is based on the work of linguists, geographers, and cartographers, who use a variety of source 
materials, and is accomplished, if possible, with the cooperation of the country covered.

INTRODUCTION 



This gazetteer, the third edition, contains approximately 6,000 names for undersea features of the world. 
Of these names, 3,600 are jointly approved by the Board on Geographic Names (BGN) and the Secretary of 
the Interior. The remaining 2,400 names are unapproved variants. The Board and the Secretary are 
responsible for standardizing geographic feature names for Federal Government use. Research for this 
publication was completed in May 1981. 

"Undersea features" are parts of the ocean floor or seabed that have measurable relief or can be 
delimited by relief. Geographic names are not approved for geological or geophysical features that have 
no surface expression, e.g., magnetic features. 

This gazetteer incorporates new names, changes to some older names, and other modifications 
approved since the second edition (1971). The undersea feature names in this publication supersede those 
in all previous BGN Gazetteers or in other Defense Mapping Agency publications. 

Format of the gazetteer 

The first section of the gazetteer is an alphabetized, cross-referenced list of names used for undersea 
features. The second section lists the same names within blocks bounded by parallels and meridians at 30° 
intervals as shown on the map which accompanies that section. 

The first column of the gazetteer contains both approved and unapproved names. Those which are 
unapproved are cross referenced to the approved form by use of the word "see." 

The second column contains designations that identify the kind of topographic feature to which the 
name applies. The designator is usually the same as the generic term (see "Naming of features") in the 
approved name. However, it will differ when a generic that is not properly descriptive under BGN defini- 
tions is retained as part of the name because of established usage. 

The third and fourth columns contain geographic coordinates, with the longitude based on 
Greenwich. Coordinates are taken at the center of the feature and serve only for identification. 



Naming of features 

Most names in the gazetteer consist of two parts: a specific term and a generic term. The specific 
term is the name applied to a feature, while the generic term is descriptive of the feature. In the name 
Conway Ridge, for example, "Conway" is the specific term and "Ridge" is the generic term. Some names 
from non-English languages may have both of these terms combined in one word. 

BGN practices appHed in the official standardization of the approved names in this gazetteer are 
listed below. These practices generally conform to those that, at time of publication, were under consid- 
eration by the United Nations and the International Hydrographic Organization (IHO) as international 
standards. 

1. The Board will consider appropriate name proposals by United States nationals for undersea 
features in international waters. V 

2. The Board will consider name proposals for features under United States territorial waters on the 
same basis as other domestic names. 

3. Prior to the naming of a feature, its character, extent and position shall be identified. Positions 
shall be given in terms of geographic coordinates. If it is necessary to refer to a feature before such 
full identification is established, it is suggested that the reference be by generic term and coordi- 
nates. In these cases, when the character is indefinite, (?) should follow the generic term, and 
when the position is indefinite, (PA), for "Position Approximate," should follow the coordinates. 

4. Undersea names in the immediate vicinity of the coast of another country will be treated as 
names in that country. 

5. The Board will ordinarily approve names of undersea features beyond limits of the United States 
that are bestowed, or approved, by other countries or nationals of other countries unless there is 
some conflict or other question. Generics in English, if appropriate to the feature, will be accepted; 
those in other languages will be translated. 

6. Procedures for selection of specific terms: 

A. It is long-established BGN policy to favor short and simple names as the most efficient, other 
factors being equal. 

B. Specific terms in the names of major undersea features should indicate, if feasible, the general 
location of the area in which they lie, e.g., Mariana Trench, Ninetyeast Ridge. 

(1) In some cases, this can be accomplished simply by using the same specific term in the 
names of adjoining features, e.g., Aleutian Ridge, Aleutian Basin, Aleutian Trench, 
Mariana Ridge, Mariana Trench, Bellona Plateau, Bellona Reefs, Bellona Shoal. 

(2) In some cases, the specific term may indicate direction from a large well-known associated 
feature, e.g.. South Honshu Ridge, West Caroline Basin. 

(3) In cases where extent of a long linear feature needs to be identified and the extremities can 
be identified by named geographic features, the names of those features may be hyphen- 
ated as the specific terms, e.g., Azores-Gibraltar Ridge, Peru-Chile Trench. 

(4) Canyons, since they usually extend close to the shore, are normally given the names of 
rivers, points, or other readily identifiable named land features as specific terms, e.g., 
Hudson Canyon, Barrow Canyon, and Norfolk Canyon. 

C. Specific names for other features can commemorate ships, individuals, expeditions, and 
organizations and institutions involved in the study of the seas. However, commemoration is 



VI 



a secondary consideration in naming; the primary concern is to provide effective, conveniently 
usable, and appropriate reference. 

(1) The name of the ship that discovered the feature may be used. If that name has been 
previously used for a similar feature, then the name of the ship that verified the feature 
may be used. 

(2) Names of individuals may include: 

a. Persons associated with the discovery and recognition of a feature including the cap- 
tain of the ship, expedition leaders or survey party chiefs, and those in charge at the 
time of discovery and recognition. 

b. Persons specifically involved in the interpretation of data leading to the recognition of 
the unique character of a feature. 

c. Persons who have made important contributions to knowledge of the oceans, e.g., 
Maury Seachannel, Ewing Seamount. 

d. Persons who are prominent in the history of a nation. 

D. It is permissible to name groups of features after specific categories of historic individu- 
als, mythical figures, constellations, fish, birds, animals, etc. Examples are: 
Mathematicians Seamounts: Archimedes Seamount, Euclid Seamount, Gauss Seamount 
Musicians Seamounts: Bach Seamount, Brahms Seamount, Schubert Seamount 

E. Descriptive names will be acceptable if not duplicated, particularly when they refer to distin- 
guishing characteristics, e.g.. Hook Ridge, Horseshoe Seamounts. 

F. Names considered inappropriate include: 

(1) Names applied to similar features elsewhere. 

(2) Full names or unwieldy titles of individuals, institutions or organizations. 

(3) Names of commercial products or their manufacturers. 

(4) Names of individuals proposed because of relationship or friendship with the proponent. 

7. Names that have been in use for many years may be accepted even though they do not coincide 
with the above policy. 

The following generic terms and definitions are currently used by the BGN. Since earlier editions of 
this gazetteer, some terms and definitions have been changed to reflect new developments in undersea 
exploration and mapping. A comparison with terms and definitions in the second edition (1971) will 
illustrate the changes. 

Generic terms and their definitions deal only with the shape of a feature as depicted by bathymetric contours. 
The terms purposely do not connote process of formation or genesis. The definitions are intentionally general 
and nontechnical. 

A geographic name serves to identify a feature, not to describe it completely. For the sake of brevity, 
modifying adjectives in terms such as abyssal plain, archipelagic apron, continental (or insular) border- 
land/shelf/slope, and deep-sea fan, are customarily dropped when the terms are used as generics in 
geographic names. The simplification of terms for use in names does not preclude their use in descriptive 
text. The Sohm Plain, for example, is an abyssal plain, and the Amazon Fan is a deep-sea fan. 

Italicized terms in the following definitions are themselves defined in the list. Asterisks indicate 
minor-feature terms and definitions recently approved by BGN. With some few exceptions, including 
minor-feature terms and definitions, the terminology below agrees with that being considered for 
approval by the UN and IHO. 



Vll 



apron — a gentle slope, with a generally smooth surface, particularly found around groups of islands 

and seamounts. 
bank— an elevation, typically located on a shelf, over which the depth of water is relatively shallow 

but sufficient for safe surface navigation. 
basin — a depression more or less equidimensional in plan and of variable extent. 
*bench — a small terrace, 
borderland — a region adjacent to a continent, normally occupied by or bordering a shelf, that is 

highly irregular with depths well in excess of those typical of a shelf, 
canyon— a relatively narrow, deep depression with steep sides, the bottom of which generally has 

a continuous slope. 
continenlal rise— a gentle slope rising from oceanic depths towards the foot of a continental slope. 
Cordillera — an entire mountain system including all the subordinate ranges, interior plateaus, and basins,

secichunnel — a continuously sloping, elongated depression commonly found in fans or plains and 

customarily bordered by levees on one or two sides. 
seamoun/— an elevation rising generally more than 1,000 meters and of limited extent across the 

summit. 
shelf — a zone adjacent to a continent (or around an island) that extends from the low water line 

to a depth at which there is usually a marked increase of slope towards oceanic depths. 
shelf valley — a valley on the shelf, generally the shoreward extension of a canyon, 
shoal — a hazard to navigation with a depth of 20 meters or less, composed of unconsolidated 

material. 
.s/7/ — the low part of a gap or saddle separating basins, 
slope — the slope seaward from the shelf edge to the beginning of a continental rise or the point 

where there is a general reduction in slope. 
spur— a subordinate elevation, ridge, or rise projecting outward from a larger feature. 
tablemount (or guyot) — a seamount having a comparatively smooth, flat top. 
terrace— a relatively flat horizontal or gently inclined surface, sometimes long and narrow, 

which is bounded by a steeper ascending slope on one side and by a steeper descending slope 

on the opposite side. 
tongue — an elongate (tongue-like) extension of flat sea floor into an adjacent higher feature. 
trench — a long, narrow, characteristically very deep and asymmetrical depression of the sea floor, 

with relatively steep sides. 
trough — a long depression of the sea floor characteristically flat bottomed and steep sided, and 

normally shallower than a trench, 
valley — a relatively shallow, wide depression, the bottom of which usually has a continuous gradient. 

(This term is generally not used for features that have canyon-like characteristics for a 

significant portion of their extent.) 

The terms arch and arrugado have not been incorporated in the above list, but they do appear in 
the names Hawaiian Arch and Guadalupe Arrugado which have been approved by the BGN on the 
basis of the names' established usage. The two names have not been given designations in this gazet- 
teer. Hawaiian Arch is a low bulge around the southeastern end of the island of Hawaii, and 
Guadalupe Arrugado is an area of subdued corrugations. 

Name proposal form 

Undersea name proposal forms are provided in this publication to facilitate submittal and expedite 
approval and promulgation of names. Anyone may propose a name for an unnamed undersea feature 
that has been adequately identified as to type and geographic location. 

Users are encouraged to submit a separate form for each name proposed, copying the form if 
necessary, and filling in all the blanks that are pertinent. They should give coordinates of latitude and 
longitude taken at the approximate center of the feature and read closely enough to sufficiently identify 
the feature. Additional coordinates for extremities of large features are helpful. 

For "kind of feature," use the appropriate term from the list of terms and definitions in this gazet- 
teer. This term should be used also as the generic term in the name. If the feature is of a kind not 
covered by these terms or definitions, explain in a supplementary note. 



IX 



Although "reference to prior publication" is provided for in the proposal form, it is hoped that 
authors will refer new names to the Board before publication. Every effort will be made to act on them 
in time to accommodate publication schedules. 

Advisory Committee on Undersea Features 

All of the decisions by the Board on Geographic Names on these undersea names have been approved 
upon the recommendation of its Advisory Committee on Undersea Features. The present members of 
the advisory committee are Joshua I. Tracey, Jr. (Geological Survey), Chairman, Philip M. Cohen (National 
Oceanic and Atmospheric Administration), G. Leonard Johnson (Office of Naval Research), Richard B. 
Perry (National Ocean Survey), Jack W. Pierce (Smithsonian Institution) and Richard R. Randall, Executive 
Secretary of BGN, ex officio. The members serve as individuals with special knowledge, not as 
representatives of agencies. 

Others who have served on the Committee since it was first constituted late in 1962, with their 
Government affiliation while serving, are A.W. Anderson, John O. Boyer and Ned A. Ostenso (NOAA), 
John V. Byrne and Joe S. Creager (National Science Foundation), John Lyman (National Science 
Foundation/Fish and Wildlife Service), Fredrick M. Edvalson (Naval Oceanographic Office), John B. 
Hersey (Office of Naval Research), Harry Ladd (Geological Survey), H.W. Menard (Executive Office of 
the President), Harley D. Nygren, Harris B. Stewart, Jr., Lome G. Taylor and Miller J. Tonkel 
(Environmental Science Services Administration), Roger S. Revelle (Department of the Interior), Charles D. 
Rouse (Defense Mapping Agency) and I. Eugene Wallen (Smithsonian Institution). Meredith F. Burrill, 
Executive Secretary of BGN for many years, was an ex officio member from 1962 to 1973. 

The Committee has met more than 200 times. Record maintenance and gazetteer preparation are 
done by the Support Division of the Defense Mapping Agency Hydrographic/Topographic Center. 
Research assistance has been provided by, successively, staff geographers Fred G. Alberts, William Lloyd, 
Boyd D. Peterson, and William R. Garren.
