Most of the data were collected in the vicinities of Hispaniola, Puerto Rico, and the Virgin Islands. Acceptable data included 78 bathythermograms (BT's), 22 bottom sediment samples, and 16 water transparency (Secchi disc) and color (Forel scale) observations. The data are a useful contribution to knowledge of the marine environment of the Caribbean Sea and will be available to agencies and institutions through the National Oceanographic Data Center. ATWOOD S. BARWICK Nearshore Surveys Division Oceanographic Surveys Department This report has been reviewed and is approved for release as an UNCLASSIFIED Informal Report. L. B. BERTHOLF Director, Nearshore Surveys Division I. INTRODUCTION A. Purpose. This report presents Project FLOOD oceanographic data collected in the Caribbean Sea by Mine Divisions 41, 45, and 85 from August 1967 to August 1968 (Operation Numbers 928018, 928023, and 928041). Survey operations were in the vicinities of Hispaniola, Puerto Rico, the Virgin Islands, and the British West Indies, and during-ship transits between east coast United States ports, Puerto Rico, and Curacao. The following ships participated in the FLOOD operations: MINEDIV 41 MINEDIV 45 MINEDIV 85 USS FRIGATE BIRD (MSC 191) USS OBSERVER (MSO 461) USS NOTABLE (MSO 460) USS HUMMINGBIRD (MSC 192) USS AFFRAY (MSO 511) USS SALUTE (MSO 470) USS JACANA (MSC 193) USS ALACRITY (MSO 520) USS ABILITY (MSO 519) USS LIMPKIN (MSC 195) This FLOOD report is one of a continuing series that began with IMR 0-30-63 (Underwood, 1963) which contained the oceanographic data collected by several mine divisions in the Mediterranean Sea between May 1961 and July 1962. The FLOOD reports serve the following purposes: (1) as a vehicle for communicating FLOOD data to prospective users, (2) as an evaluation of the data and of the collecting methods, and (3) to focus the attention of future participating ships on common errors made in collecting and recording oceanographic data. B. Background. Project FLOOD (FLeet Observations of Oceanographic Data) was established in 1960 as a means of developing the latent oceanographic survey potential of the U.S. Navy. To date, the Project FLOOD effort has been confined to the Mine Forces. Through the cooperation of Commander Mine Forces, U.S. Atlantic Fleet, and Commander Mine Forces, U.S. Pacific Fleet, all minesweepers deploying to foreign areas are equipped with oceanographic instruments, and the ships' crews are trained in their use. In the Mediterranean Sea, Commander, Sixth Fleet, frequently schedules operational periods for Mine Divisions to conduct FLOOD surveys. However, operational schedules to date by Mine Divisions in the Caribbean Sea have not permitted scheduled FLOOD surveys. The data in this report were collected on an opportunity basis during regular Mine Division operations. C. Data Acquisition Plan. The procedures employed by Mine Divisions 41, 45, and 85 in the collection of data were set forth in "Technical Specifications and Guidelines, Project FLOOD' (NAVOCEANO, rev. 1967). In these specifications, the Caribbean Sea-Gulf of Mexico area is divided into 13 regions as shown in Figure 1. Most of the data in this report were collected in Regions 7 and 10. The specifications include operating instructions for the use of FLOOD equipment and the locations in each region where there is a deficiency of various types of oceanographic data. The possibilities of duplicating effort or of collecting unneeded data are therefore reduced. D. Operational Events. The data collected by Mine Divisions 41, 45, and 85 included bathythermograms (BT's) (Fig. 2), bottom sediment samples (Fig. 3), and water transparency (Secchi disc) and color (Forel scale) observations (Fig. 4). The mine divisions were briefed and trained in Project FLOOD operations by a NAVOCFANO representative before departing from home port. 1. Mine Division 45. MINEDIV 45 departed Charleston, South Carolina, on 7 August 1967 for operations in the Caribbean Sea. On 9 August, OBSERVER collected one bottom sample on Navidad Bank north of Hispaniola. Two BT's also were taken in this area on 8 September. On 30 and 31 August, a second bottom sample and two BT's were taken north of Vieques Island. In addition, 1i ET's were obtained from 2 to 6 November in transit from an area southwest of Cuba to Charleston. Between 11 and 15 October, AFFRAY obtained 9 bottom samples and 9 Secchi disc and Forel scale observations on Mouchoir and Silver Banks north of Hispaniola between Puerto Rico and the Virgin Islands. On 8 September, ALACRITY collected two bottom samples and two BT's on Navidad Bank. MINEDIV 45 returned to Charleston on 8 November. 2. Mine Division 85. MINEDIV 85 departed Charleston on 2 January 1968 for operations in the Caribbean Sea. On 18 January, ABILITY took one BT and two bottom samples off the coast of Vieques Island. Also at this location, divers from ABILITY obtained one bottom sample and one Secchi disc and Forel scale observation. From 20 to 27 January, SALUTE collected nine BT's in transit between Puerto Rico and Curacao. An additional three BT's were obtained from 20 to 25 February in the vicinity of the Anegada Passage (east of Anegada Island and Virgin Gorda Island). On 23 February, NOTABLE collected a bottom sample off the west coast of Guadalupe Island. MINEDIV 85 returned to Charleston on 24 March. 3. Mine Division 41. MINEDIV 41 departed from Little Creek, Norfolk, Virginia, on 10 June 1968. From 11 to 16 June, JACANA collected 16 BT's while in transit from Little Creek to Puerto Rico. After departure from Puerto Rico, 20 additional BT's were taken from 2 to 27 July while circumnavigating Hispaniola and on the return to Puerto Rico. FRIGATE BIRD and LIMPKIN collected 2 and 3 bottom samples, respec- tively, off the south coast of Puerto Rico from 27 to 28 June. LIMPKIN also collected three Secchi disc and Forel scale observations off the south coasts of Puerto Rico and Hispaniola. From 5 to 23 July, Ht-LrMI4NBIRD made three Secchi disc and Forel scale observations off the west and north coasts of Hisraniola and south of Vieques Island. MINEDIV 41 returned to Little Creek on 21 August. On an earlier deployment in August 1967, LIMPKIN participated in FLOOD operations by collecting 12 BT's north of Hispaniola and along the coast of Florida. Ii. RESULTS A. Data Inventory. The oceanographic data reported by Mine Divisions 41, 45, and 85 consisted of the following: MINEDIV 41 Received Acceptable BT's 54 48 Bottom Samples 5 5 Secchi disc/Forel scale obs. 6 6 MINEDIV 45 BT's 18 17 Bottom samples 13 13 Secchi disc/Forel scale obs. 9 9 KTNEDIV 85 BT's 13 13 Bottom samples 4 4 Secchi disc/Forel scale obs. 1 1 BT's were collected with mechanical bathythermographs. The BT slides were processed at the National Oceanographic Data Center (NODC) and are filed under the following reference numbers: OBSERVER 21401 ALACRITY 21698 ABILITY 22036 SALUTE 21970 JACANA 22321 (June) and 22435 (July) LIM[PKIN 21188 3 The BT data are not included in this report, but typical traces are presented in F:igurc 5. Most of the bottorn samples were obtained with Alpine Model 244 or Dietz-LaFond snapper-type grab samplers which retain about 1 pint of sediment. One sample was collected by divers. All samples were stored in plastic bags and forwarded to NAVOCEtNO for sediment size and composition analyses, Computer-processed data sheets of these analyses and descriptive log sheets are presented in Appendix A. Water transparency observations were obtained with a standard 30 cm Secchi disc with a matte white surface on one side and a matte black surface on the other. Water color observations were obtained with a Forel scale which consists of 11 vials of ammoniacal copper sulfate and neutral potassium chromate in various proportions to provide a continuous color gradation from deep blue to green. These data are presented in Appendix B. B. Quality Control. During the processing of FLOOD data, an effort is made to determine the precision of the data and to eliminate erroneous values. 1. Temperature Data. No satisfactory method has been found for validating the accuracy of the BT data in the Caribbean Sea FLOOD operations. The ships were reauested to check the BT periodically by immersing it in a bucket of water with the calibrated thermometer provided with the FLOOD equipment, but no bucket calibration data were received. Comparison of the BT traces with the sea surface temperatures produced the following results: Ship BT Serial No. Correction Applied Deviation JACANA 16197 (June) +5.4 0 F +I.5 0 F LIMPKIN 528B 0 +l.0 0 F OBSERVER 14682 +3.2 0 F +2.0 0 F SALUTE 11924 +0.9 0 F +I.5 0 F ABILITY 8924C Insufficient Data ALACRITY 12463A 2. Bottom Grab Samples. The bottom grab samples were analyzed for sediment size and composition at NAVOCEANO in accordance with the technique given by Richards (1962). 3. Water Transparency and Color Data. No method has been devised for validating Secchi disc data. This author has observed that Forel color identifications by different observers may differ by a scale number, and this difference appears more likely to happen at the higher scale numbers where the differences between colors become more subtle. Heavers (1967) observed 4 that for different surface illuminations at the same location the Forel scale value probably does not differ by more than +1 scale number. 4. Diver Observations. The diver estimation of the bottom composition and the results of the sample analysis suggest that either the diver is unable to make an accurate estimation or that the samnle is not representative. Comparison of the diver visibility data with the Secchi disc data collected from the surface is difficult because of the effects of the air-sea interface. Divers are instructed to use the black side of their disc as the target, but the vertical visibility recorded is in much closer agreement with the white side of the surface-observed disc. III. REVIEW The results that have been obtained from the Caribbean Sea waters to date have been meager when compared with the results from other areas. The reason is due largely to numerous, unexpected operational schedule changes. However, a beginning has been made which hopefully will lead to a productive program of oceanographic observations. The greatest problem affecting the data in this report is the lack of bathythermograph accuracy checks which severely reduces the potential accuracy of the data. Accuracies of +0.5 0 F should be achievable with proper calibration checks. On the positive side, the BT data received from these shins were for the most part clean and neatly annotated. Only one instance of severe hysteresis problems was indicated. Several instances were noted where the BT was lowered below its maximum depth (esnecially on JACANA and SALUTE). This practice should be avoided. IV. SIT2A.P.Y Mine Divisions 41, 45, and 85 have made a contribution to knowledge of the marine environment of the Caribbean Sea. Project FLOOD environ- mental data are used in the preparation of various data sheets, pilots, atlases, sailing directions, and other publications and instructions. The data will be available to agencies and institutions through NODC. The data in the Apoendixes were checked for errors and, where possible, an evaluation of accuracy was made. The real and potential sources of errors in data collection are discussed in this report for the benefit of future participating ships. The nrincinle source of error is the lack of satisfactory bathythermoýraph calibration checks. 5 V. BIBLIOGRAPHY Heavers, Richard M., 1967.

ABSTRACT Mine Divisions 41, 45, and 85 collected oceanographic data in the Caribbean Sea from August 1967 to August 1968 in supnort of Project FLOOD. Most of the data were collected in the vicinities of Iispaniola, Puerto Rico, and the Virgin Islands. Acceptable data included 78 bathythermograms (BT's), 22 bottom sediment samples, and 16 water transparency (Secchi disc) and color (Forel scale) observations. The data are a useful contribution to knowledge of the marine environment of the Caribbean Sea and will be available to agencies and institutions through the National Oceanogranhic Data Center.
