GILL CRUISE 1 The program of the South Atlantic Fishery Investigations evolved from: (1) the interest of the U.S. Fish and Wildlife Service in the bio- logical and chemical conditions in the offshore waters from Cape Hatteras to Florida Straits; (2) the interest of the South Atlantic Section, Atlantic States Marine Fisheries Commission in these matters; (3) the interest of the U.S. Navy Hydrographic Office in the physical oceanography of the same region; and (4) the interest of the Office of Naval Research in the deep scattering layer and related subjects . During 1952 the Fish and Wildlife Service M/V Theodore N. Gill was converted and out- fitted. She has a length of 97 feet, beam of 21.5 feet, draft of 1 1 . 5 feet, displacesl87 tons, and has a cruising range of 3500 miles. Navi- gation and communications equipment includes Sperry Automatic Pilot, CG Model RD-137 Loran, Navy Model SO-1 Radar, Edo AN/UON- 1B Echo Sounder, RCA Transceiver Type CRM, and National Type CNA receiver. The basic oceanographic equipment includes BT winch (1200 foot capacity), Markey hydrographic winch (electric powered, with capacity of 5000 meters of 5/32" stainless steel cable), and a two-drum Stroudsburg trawling winch (hydraul- ic powered, with 1/4" stainless steel cable) for plankton tows. There are accommodations for eight scientists and a crew of ten . The initial effort was a cruise in July, 1952 . This was a cooperative Navy Hydrographic Office Office of Naval Research program in- volving: (1) sound velocity meter tests; (2) scattering layer observations; and (3) the first in a series of twenty -four to forty - eight hour oceanographic stations, termed "standard stations . This work continued until December, 1952. By the end of 1952 the Fish and Wildlife Service's South Atlantic Fishery Investigations had established headquarters at Brunswick, Georgia, and developed to the operational stage A cooperative operational plan and agreement was reached by the Service, the Navy Hydrographic Office, and the Office of Naval Research. The Service set up a pat- tern of 80 regular stations between Jupiter Light (Florida Straits) and Cape Hatteras ex- tending in area from near the beaches to beyond the axis of the Gulf Stream. These stations were 20 miles apart on the east-west lines, which were in turn, 40 miles apart in the north -south direction, with stations es tablished inshore between some of the east- west lines. The standard station was maintained in its location off Elbow Cay, Bahamas. Additionally, at the request of the Navy Hydrographic Office, nine special sta- tions were located farther offshore. This basic cruise plan is shown in Figure 1. The ultimate objective of the investigations is to ascertain the potential productivity of those waters adjacent to our coast from Cape Hatteras on the north to the Florida Straits on the south As a beginning to this study, a general survey of the waters was projected that had three major objectives: 1. To ascertain the distribution and concentrations of nutrients and the relations between these nutrients and the distributions and concentra- tions of the fishes, as a means of delimiting potentially productive fishing areas . 2 . To determine the presence, identity, distribution, and interrelationships of marine forms in the area as an aid in understanding the presence, abundance, availability, and fluctua- tions of the fishes. Special attention is directed to the distribution and abundance of fish eggs, larvae, and juveniles; and to the early life history of important species of the area. Figure 1 Basic station plan. 3 . To determine through oceanographic techniques, the flow pattern of the maior currents of the region, and trends in temperatures and salinities . The program developed as a cooperative venture between the Fish and Wildlife Service and the several agencies: the Navy Hydro - graphic Office and the Office of Naval Research in physical oceanography and related studies; the Georgia Game and Fish Commission in the biological inventory and nutrient studies; and the Florida State Board of Conservation (through the Marine Laboratory of the Univer - sity of Miami) in biological studies . The Woods Hole Oceanographic Institution is cooperating in the processing and analysis of data relating to physical oceanography. Field operations comprised nine cruises over the established station pattern during the period January, 1953, to December, 1954. It was agreed by the cooperating agencies that the basic data from the cruises of the Theodore N . Gill would be made available in an assembled form for each cruise. This re- port is to explain the program, operational procedure, and methods; and to present the assembled data for Cruise 1. PROCEDURES ON STATION Regular and Special Stations 1 . General observations including barometer reading, wet and dry bulb air temperatures, wind direc- tion and velocity, and observed sky, sea, and wave conditions were re- corded 2. BT casts were taken on each station. Three bathythermographs with ranges of 180, 450, and 900 feet were available: 3. Nansen bottle casts were made at standard wire depths, using 12 bottles or less per cast. A 30 cm. Secchi disc was attached directly to the hydrographic cable, and readings taken on stations during daylight hours. 4. Oxygen determinations were con- ducted aboard vessel immediately after each cast, using Wooster's modification of the Winkler method of dissolved oxygen analysis. 5. Salinity samples were collected for each cast (determinations were made in the Service's laboratory at Brunswick, Georgia). 6 . Water samples for use in the deter- mination of inorganic phosphate, total phosphorous, carbohydrates, proteins, and nitrate -nitrite were collected for each cast (analyses were accomplished in the Service's laboratory at Brunswick, Georgia. 7. Bottom sediment samples were ob- tained, using a modified orange peel dredge (lead weights were added and covers were placed over the blades to prevent the sample from washing out) . Half of each sample was furnished to the Navy Hydro - graphic Office for analysis . 8 GEK measurements from the Gill 9. were found impractical, and use of the instrument was abandoned very early in the program . Plankton tows with a half-meter silk net were made on each station . The continuous plankton sampler was run continuously. 10. Dip-net fishing was conducted on each station as conditions permitted. 11 . Feather and bone jigs were trolled between stations. Standard Station The water depth in the area of operation was too great for anchoring, so the position of 26°21.5'N and 76°46'W was held within the limits of the navigational equipment aboard. This station was located so that it was free of the effects of the Gulf Stream . It was of 48 hours duration when conditions permitted. Observations were similar to those taken for regular and special stations except:. 1 . BT lowerings were made to 900 feet before and after each Nan sen bottle cast. 2 . Nansen bottle casts were lowered two hours after completion of the previous cast, and were made to a depth of 700 meters with 12 bottles spaced at standard depths . Samples for oxygen and salinity determina- tions were drawn for each cast and treated as on regular stations. Water samples for the other chem- ical determinations were drawn on four casts during the standard sta- tion (these at dawn, mid-day, dusk, and mid-night as nearly as possible). 3 . Special plankton tows were made for the Office of Naval Research for deep scattering layer investigation (four tows with half-meter silk nets during the station timed to represent the periods of dawn, mid-day, dusk, and mid-night) . Towing depths were surface, 100, and 200 meters . 4. Hydrophone and special echo- ranging observations were made by the Office of Naval Research . 5. Dip-netting was conducted continu- ously. CHEMICAL METHODS AND PROCEDURES General Containers used for collection of samples 1 . Total phosphorous and salinity - 4 oz . prescription bottles having plastic screw caps with vinyl liners. 2. Inorganic phosphate - 200 mm. culture tubes with polyethylene screw caps. 3 . Carbohydrates and proteins - 125 mm . culture tubes with plastic screw caps having poly- ethylene inserts. 4. Nitrate -nitrite - 60 mm. vials with plastic screw caps having polyethylene inserts. 5 . Oxygen - standard 250 ml . oxygen bottles. Initial preparation of containers Culture tubes and vials were aged in con- centrated sulfuric acid for approximately one week, thoroughly rinsed with tap water, fol- lowed by three rinses with distilled water. Prescription and oxygen bottles were washed with a detergent, rinsed with tap water, fol- lowed by three rinses with distilled water. A small amount of thorium carbonate was added to each total phosphorous sample bottle at the shore laboratory (to prevent loss of organic phosphorous by attachment to the sides of the bottle). Notes on collection of samples at sea Total phosphorous sample bottles "baited with thorium carbonate were not rinsed at sea before drawing samples . All other bottles, tubes, and vials were rinsed twice with sea water from the Nansen bottles before samples were drawn . Vials and tubes containing samples for in- organic phosphate, carbohydrates, proteins, and nitrate -nitrite were prepared for freezing by taping the junction of the cap and the tube with plastic electrician's tape (to prevent con- tamination of samples by ethylene glycol) . 1/ They were then immersed in 38% ethylene glycol freeze bath until completely frozen, after which they were removed from the bath and stored in a deep-freezer at 0° to -10°F (Collier and Marvin 1953). General notes on methods StocK solutions of standards were prepared with distilled water, and subsequent dilutions made with synthetic sea water . Synthetic sea water for total phosphorous, inorganic phos- phate, and carbohydrate analyses was pre- pared by dissolving 35 gm . sodium chloride in distilled water and diluting to one liter; for nitrate -nitrite, 20 ml. cone, hydrochloric acid was added to distilled water and diluted to one liter; and for proteins, by dissolving 35 gm. sodium chloride and 6.5 gm. magnes- ium sulphate in distilled water and diluting to one liter. Densities were read from scale "A" on the Fisher instrument, and from the optical density scale on the Beckman instrument, after the instruments were adjusted to zero with a distilled water blank. Density readings were recorded as -log T. Notes on calculation of concen- tration values Standardization curves were prepared for each set of standards by plotting Tog T values against concentrations of standards . Those for nitrate -nitrite were fitted as smooth curves through all points, while all others were fitted as straight lines. Concentration values for nitrate -nitrite were determined by direct reading from standardization curves. Those for total phos- phorous and inorganic phosphate were calcu- lated by dividing the -log T values by a factor (equivalent to "the slope of the line" in the standardization curves). Those for carbo- hydrates and proteins were calculated by sub- tracting the -log T value for the zero concentration of the standard from the -log T values of the samples, and then dividing by the factor. Concentration values were calculated to the nearest 0.5 of a unit for nitrate -nitrite, and to the nearest 0.1 of a unit for total phosphor ous, inorganic phosphate, carbohydrates, and proteins. Chemicals used, with the exception of N- ethylcarbazole, were reagent grade. A set of standards was run with each batch of sea water samples and treated in the same manner as the samples. A Beckman DU Spectrophotometer was used in the protein determination, and a Fisher AC Electrophotometer used for total phosphorous, inorganic phosphate, nitrate - nitrite, and carbohydrate determinations. 1/ Beginning with Cruise 6, samples for carbo- hydrates were placed immediately in the deep freeze, to eliminate all contact with ethylene glycol .

A 40 -pound streamline depressor was used as a weight, and an Atlas type cur- rent meter suspended in the mouth of the net registered the flow of water into the net. Figure 2 . With the ship underway the net was lowered slowly to a depth of 70 meters (100 meters of cable out), or less in shallow water, and then retrieved at die rate necessary to bring it to the surface in approximately 20 minutes. The ship's speed during the tow was 1-2 knots, and the engine was started and stopped as often as necessary to maintain a cable angle of approx- imately 45 degrees. This angle of stray, measured continuously with an inclinometer suspended from the towing boom and riding freely on the cable, was recorded every min- ute, or less frequently in shallow water. Plankton samples were preserved in 5% buf- fered formalin . The depth of a tow was calculated by multi- plying the cosine of the angle of stray by the amount of cable out . Volumes of water strained An estimate of the volume of water strained during a tow was derived from the revolutions registered by the flow meter mounted in the mouth of the net. Flow meters were calibrat- ed by towing them at regular towing speed over a known distance. From this a meter factor of "meters of distance per revolution" was ob- tained. This factor was multiplied by the area of the net opening, and the product applied to the meter readings for each tow, thus convert- ing the readings to "cubic meters of water strained." Meter pointers were zeroed prior to each tow to prevent double errors in readings . «*^fl^flHH Figure 2. --Half -meter silk net. Numbers of organisms Each plankton sample was examined in 10- ml. portions under a low -power binocular microscope, and the fish eggs, fish larvae, and amphioxi were removed and counted. The wet volumes of plankton were then determined by displacement (drained plankton placed in graduated cylinder containing a known volume of 5 percent buffered formalin) . Numbers of organisms other than fish eggs and larvae and amphioxi were estimated by counting those in aliquot portions of a sample and adjusting the counts to the entire sample volume. The procedure was as follows: (1) the sample was stirred thoroughly, and a 10 ml . portion removed, by dipping with a 10 ml . beaker, to a dish marked with a centimeter grid; (2) the more numerous organisms were counted in six preselected centimeter squares, and the less numerous ones counted in the en- tire dish; (3) the portion was then returned to sample jar, the sample stirred thoroughly, and a second 10 ml . portion removed; (4) the second portion was treated in same manner as the first; and (5) the counts were averaged and then adjusted to the entire sample volume by multiplying by the appropriate factor. Num- bers of the various organisms per cubic meter of water strained were calculated by dividing sample totals by volumes of water strained. Continuous Plankton Sampler Plankton samples were also taken with a continuous sampler designed by Albert W . Collier, Jr , Chief, Gulf Fishery Investiga- tions, Fish and Wildlife Service. A descrip- tion of this sampler has not been published, but general construction details and operation- al procedure will be presented here . Figure 3. The sampler consists of a circular trough divided into eight compartments, and is driven by an electric motor at the rate of one revolu- tion per eight hours. Extending down from each compartment is a tube fitted at its lower end with a clamp which holds a 1 -1/4" No . 1 silk filtering disc . A reverse bend in the dis- charge tube below the clamp retains sufficient water to cover the silk, thus preventing filtered organisms from drying out. Sea water is pumped from a sea chest located several feet below the ship's water line, through a standard water meter, and into the sampler . As the sampler trough revolves, each compartment receives water for one hour . After one revolution of the trough (eight hours), a timer switch shuts off the sampler and pump motors. The filtering discs are then removed, preserved in 5 per- cent formalin, and replaced with new silks. Each revolution constitutes a "run' . The sampler is permitted to run continuously, except for the time needed to change silks and when the ship is entering or leaving a harbor (where sand and silt may jam the water meter) . The flow of water into the sampler is regulated according to the density of planKton encountered (in shallow waters phytoplankton plugs the filtering disc rapidly if flow is not reduced) . A pressure gauge in the line be- tween the meter and the sampler provides for uniform adjustment of the flow. From 50 to 100 gallons of water pass into each compart- ment during the hour it receives water. The silks are examined individually, and counts made of all organisms present . The counts are then adjusted to "Number per cubic meter of water strained" . The position of the ship at the time the center of each com- partment is reached is accepted as the loca- tion of sampling for the compartment involved. Generally, the trough does not matce one revolution in exactly eight hours, and the time for each compartment is adjusted accordingly. Dip -netting Dip -netting for larval and juvenile forms of fish was conducted on station when seas and weather conditions permitted. Dip nets used were 18 inches in diameter, lined with 1/4-inch nylon mesh, and were fitted with 12 foot bamboo handles . Spot and floodlights were used at night to attract fish. In general, dip-netting at night under the lights proved more productive than dip -netting during the 10 u H | a o -p ■3 n3 rH ft Cfi O G tH -P a o o I I ro (U 3 •rH p4 11 day, for most species . Trolling Three -ounce red and white nylon jigs were trolled at 9-10 knots between all stations during daylight hours, and hand-lines using cut or live bait were fished on some shallow stations. All fish caught were identified, weighed, and measured, and stomach con- tents were preserved. OCEANOGRAPHIC METHODS AND PROCEDURES Standard methods employed by the U.S. Navy Hydrographic Office were used aboard the Gill and in processing the data. Salinity, temperature, and density pro - files were prepared by Mr . Dean Bumpus of the Woods Hole Oceanographic Institution. NARRATIVE ACCOUNT OF CRUISE 1 The Theodore N. Gill departed from Brunswicic, Georgia on February 10, 1953, and proceeded to the standard station along the track as shown in Figure 4. Hourly bathy- thermograph observations were made while enroute, except when passing through the Gulf Stream and the Antilles Current when BT low- erings were made every half hour . The site was reached on February 12. Nine nansen bottle casts were made to 700 meters, at intervals of about two hours. Half-hourly bathythermograph observations, Secchi disc readings during daylight casts, simultaneous routine meteorological observations, and special plamaon tows for deep scattering layer studies were also made during the occupation of the standard station. Thirty-four hours (interrupted on February 13 by a trip to Nassau, BWI, for winch repairs) were spent on the standard station . Upon completion of the standard station the Gill proceeded to and began occupying the series of regular stations of the southern leg on February 16, 1953 . Due to high winds and heavy seas, only 16 of the proposed 34 regular stations could be made . On several occasions it was necessary for the vessel to proceed to the nearest shelter until the weather moderated. The Gill returned to Brunswick on February 22, 1953. After a brief stopover in Brunswick for supplies, the Gill departed on February 26, 1953, and proceeded northward to occupy regular stations 35 through 80 and special stations 1 through 4 of the northern leg of the cruise. Adverse weather conditions in the Cape Hatteras area prevented occupation of 10 regular and the 4 special stations. The vessel returned to Brunswick on March 10, 1953. Cruise track chart is given in Figure 4. During the cruise, Nansen casts were made on all regular stations occupied. Bot- tom samples were obtained on southern leg stations and a few northern leg stations with the orange peel sampler (sampler lost early on northern leg) . Coring was attempted using Phleger corer, but it proved ineffective on the types of bottom encountered. Water samples were collected for salinity, nitrate, carbohy- drates, inorganic phosphate, total phosphor- ous, and proteins on each station. Oxygen determinations were made aboard vessel for each station. BT's and associated meteoro- logical observations were taken on each station and hourly between stations . Oblique plankton hauls with a half-meter silic net were made on each station. Dip -netting was carried out day and night when conditions permitted. Artificial lures were trolled between stations for capture of larger fish . Scientific personnel participating in the cruise were: I.

All doubtful data are indicated and were not used in the construction of the curves from which the interpolated values (standard depth values) were derived. Observed values which were obviously false were omitted entirely. A dash in a table means that no value was available. Interpolations for standard depth values for temperature, salinity, sigma-t, and oxygen were for the most part IBM calculations, but in a few instances they are manual interpola- tions from hand drawn curves; those for the chemical constituents were derived from straight lines between observed values . The profiles of salinity, temperature, and density were prepared from these data, and appear as Figures 5-15. 1 . Cruise Number. The first cruise over the established station pattern (Figure 1) will be numbered Gill 1, and sub- sequent cruises, Gill 2 through Gill 9 (only Gill 1 is covered by the present report) . 2 . Station Number. Stations are numbered consecutively, starting with one, at the beginning of each cruise. The station pattern and numbers as shown in Fig- ure 1 were maintained on each cruise. If a station or series of stations was not occupied, these station numbers are omitted. Regular stations have numbers only; standard and special stations are specifically indicated. 3 . Date. Month, day, and year are given . 4. Latitude and Longitude . The position of the station is given in degrees and minutes. 5 . Time Given in Greenwich Mean Time and is that hour nearest to the start of the first cast. 6 . Depth. Is the observed uncorrected sonic sounding for the station, record- ed in meters. 7. Wind. Wind speed is given in meters per second. Direction from which the wind blows is coded in degrees true to the nearest ten degrees. The last zero is omitted. North is 36 on this scale and calm is 00. See Table 1, Com- pass Direction Conversion Table for Wind, Sea, and Swell Directions." 14 8. Barometer. The barometric pressure is coded in millibars, neglecting the 900 or 1000 . Thus 996 millibars is coded as 96 and 1008 millibars is coded as 08. 9 . Air Temprature. Dry bulb and wet bulb temperatures are entered to the nearest tenth of a degree (centigrade) . 10. Humidity. The percent of humidity is coded directly. 4. Sigma -t. To convert to density divide by 1000 and add 1 . Thus, a sigma-t value of 22.35 converts to a density of 1.02235. 5. Dissolved Oxygen. These values are given in milliliters per-liter to two decimal places. 6. Total Phosphorous. Values are given in microgram atoms per liter to the nearest 0.1 of a unit. 11. Weather . Weather is coded as indicated in Table 2, "Numerical Weather Codes - Present Weather . ' Inorganic Phosphate. Values are given in microgram atoms per liter to the nearest 0.1 of a unit . 12 . Clouds . Cloud type and amount are coded as indicated in Table 3, "Cloud Type"; and Table 4, "Cloud Amount" 8 . Nitrate -nitrite. These values are given in microgram atoms per liter to the nearest 0.5 of a unit. 13. Sea. Sea direction and amount are coded as indicated in Table 5, "Sea Amount"; and Table 1. 14. Swell . Swell directions and amount are coded as indicated in Table 6, "Swell Amount"; and Table 1. 15. Visibility. Visibility is coded as in- dicated in Table 7, "Visibility." 16. Water Transparency. Given as meters to which a Secchi disc is visible. Subsurface Observations 1 . Sample Depth . Observed (actual) depth of each sample is given in meters. In- terpolated values at standard depths are also given. The standard depths in meters are: 0, 10, 20, 30, 50, 75, 100, 150, 200, 250, 300, 400, 500, 600, 700, 800, 1000, 1200, 1500, 2000, 2500, 3000, and thence every 1000 meters. 2. Temperature . The centigrade tempera- ture is given in degrees and hundredths. 3 . Salinity. Salinity is given in parts per thousand to two decimal places. 9. Carbohydrates (Arabinose) . These values are given in terms of milligrams per liter to the nearest 0.1 of a unit. Collier et al . (1953) presented a tech- nique for estimating certain elements of the organic materials in sea water which react to the test for carbohydrates. The carbohydrate values are given as arabinose equivalents, and are not necessarily the actual concentration of carbohydrate substances. 10. Proteins (Tyrosine) . These values are given to the nearest 0. 1 of a unit as milligrams per liter of protein material in sea water, which reacts to the test for tyrosine. Biological 1 . PlanKton volumes (half-meter silk net), Table 8. The position given is that at beginning of the tow . The depth of the haul is given from 0 to the greatest depth reached. The volumes as given are "wet volumes' (procedures for de- termination are given under methods) . Very few samples contained large or- ganisms such as jellyfish (which were removed), so that the volumes represent 15 smaller organisms. 2 Numbers of plankton organisms per cubic meter of water (half -meter net), Table 9 . The procedures for plankton tows, methods for sorting and count- ing, and calculations of numbers of organisms were described under methods . Counts are given for major groups as indicated. 3. Numbers of plankton organisms per cubic meter of water (continuous plankton sampler), Table 1U. Description of this sampler, its use, and methods of calculating numbers of organisms were given under methods. Counts are given by compartment for major groups as indicated. 4. Numbers and species of fish taken by trolling, Table 1 1 . The stage of gonad development is based on International Council classifications of gonad matur- ity for the herring (International Councils Rapports et Proces-Verbaux des Reunions, Vol. LXXIV, pp. 117, March 1931). The scale is only a guide to general classifications and must be treated as such. This scale follows: Stage I . Virgin individuals . Very small sexual organs close under vertebral column . Wine-coloured torpedo - shaped ovaries about 2 3 cm . long and 2-3 mm . thick . Eggs invisible to naked eye. Whitish or grayish brown knife -shaped testes 2-3 cm. long and 2-3 mm. broad. Stage II Maturing virgins or recover- ing spents. Ovaries some- what longer than half the length of ventral cavity, about 1 cm . diameter . Eggs small but visible to naked eye. Milt whitish, some- what bloodshot, same size as ovaries, but still thin and knife -shaped. Stage III. Sexual organs more swollen, occupying about half of ventral cavity. Stage IV. Ovaries and testes nearly filling 2/3 of ventral cavity . Eggs not transparent, milt whitish, swollen. Stage V . Sexual organs filling ventral cavity. Ovaries with some large transparent eggs. Milt white, not yet running. Stage VI . Roe and milt running (spawning) . Stage VII. Spents. Ovaries slack with residual eggs. Testes bag- gy, bloodshot . Doubtful cases are indicated by quot- ing two stages e.g. "St. I- II, St. VII II," etc. 5. Numbers and species of fish taken by dip net, Table 12. There is shown, by family, the genera and species taken. Numbers of specimens from each sta- tion are given in parentheses, followed by the approximate size or size range of standard length, in millimeters. 16 ACKNOWLEDGMENTS LITERATURE CITED Acknowledgment is made to the following agencies and individuals for contributions in securing and processing the material present- ed.
