Technical ReportIntelligent chilled mirror humidity sensor(Woods Hole Oceanographic Institution, 1988-12) Hosom, David S. ; Winget, Clifford L. ; Weisman, Sumner ; Doucet, Donald P. ; Price, James F.A new, intelligent, chilled mirror humidity instrument has been designed for use on buoys and ships. The design goal is to make high quality dew point temperature measurements for a period of up to one year from an unattended platform, while consuming as little power as possible. Nominal system accuracy is 0.3°C, and a measure of data quality is provided to indicate possible drift in calibration. Energy consumption is typically 800 Joules per measurement; standby power consumption is 0.05 watts. Control of the instrument is managed by an onboard central processing unit which is programmable in BASIC, and communication to an external data logger is provided through an RS232 compatible interface. This report describes the preliminary sensor tests that led to this new design and provides the complete technical description required for fabrication.

Technical ReportTechnical progress report : advanced marine technology 1 August 1973 - 31 January 1974(Woods Hole Oceanographic Institution, 1974-05-15) Ballard, Robert D. ; Hays, Earl E. ; Hess, Frederick R. ; Marquet, William M. ; McCamis, Marvin J. ; McElroy, Paul T. ; Winget, Clifford L.Contrary to the statement in the previous progress report (WHOI-73-92) we have decided to issue the final technical reports on Submerged navigation, Hydraulic Impact Hammer, Deep Sea Rock Drill and the Self Contained Ancillary Modular Package (SCAMP) as separate reports. These are underway in various stages and will be issued as completed. This six months has seen successful use of the navigation system in direct and surface bounce modes, testing of the "lock on" system of SCAMP to an ALVIN model and steady progress in the Modular Acoustic System.

Technical ReportTechnical progress report : advanced marine technology 1 February 1973 - 31 July 1973(Woods Hole Oceanographic Institution, 1973-12-01) Ballard, Robert D. ; Maxwell, Arthur Eugene ; Davis, Ray E. ; Eliason, Andrew H. ; Hess, Frederick R. ; McCamis, Marvin J. ; McElroy, Paul T. ; Marquet, William M. ; von Herzen, Richard P. ; Williams, David L. ; Winget, Clifford L.This report covers a period which finds several of the projects nearing completion. It is expected that the next semi-annual report should contain final technical reports on Submerged navigation, Hydraulic Impact Hammer, Deep Sea Rock Drill and the Shelf Contained Ancillary Modular Package (SCAMP). It is possible that extensive testing and use of SCAMP will not take place until next year. The responsibility for these worthwhile equipments then shifts to the users, who in most cases has been intimately involved in the development. The Submerged Navigation system continues to attract much attention both within and without the Institution. Delays in the fitting and testing of ALVIN in the Titanium hull configuration has slowed the field work with ARPA developed equipment bu the next six months should contain considerable work.

Technical ReportA technical guide to the deep submergence research vehicle (DSRV) ALVIN for use in planning scientific missions(Woods Hole Oceanographic Institution, 1967-12) Winget, Clifford L. ; McCamis, Marvin J.This report has been compiled to aid scientists and other users in planning deep submergence missions in the DSRV ALVIN. It is general in nature, and covers the personnel, electrical, mechanical, and operation aspects of the vehicle and its support ship. The intent is to aid prospective users in marrying their programs and research equipment to the vehicle. The information has been arranged in a format that will allow the scientist to review specific areas of interest. Enough technical information is provided to allow a start on designing or adapting the science mission and equipment to the existing vehicle. In the event the basic vehicle configuration is not compatible with the mission requirement, the staff of the Deep Submergence Research Vehicle Program is available for consultation or technical guidance. Profile, plan, and sectional drawings of the submersible, Figures 1 and 2, have been included to acquaint the scientist with the nomenclature and general design of the electro-mechanical systems of the vehicle. The location and general configuration of the various flood lamps, cameras, and other science equipment are clearly shown. Management policies and operational responsibilities have not been included in this report. A detailed Management Plan for the Deep Submergence Research Vehicle Program is available. Copies will be furnished to the scientific observer when requested.

Technical ReportThe design and construction of a towed multi-port water sampling probe for 100 meter depths(Woods Hole Oceanographic Institution, 1980-05) Winget, Clifford L. ; Orr, Marshall H.The experimental towed multi-port water sampler was designed to provide a shipboard science party with the capability of obtaining continuous water samples from the surface to a 100 meter depth. The device will simultaneously provide six samples spaced one meter apart in a vertical plane, while being towed by a surface support vessel at a forward speed of between two to three knots. The device consists of a bottom fish containing six electric motors, each driving an individual pump. The six water samples are pumped to the surface using separate runs of TFE Teflon tubing. The tube is mounted in a pliant fairing that also houses the lifting cable, power leads, and instrumentation bundle. A drum winch is used to store a total of 150 meters of faired cable, and is capable of raising or lowering the fish while under way. The sampler will provide a discharge flow rate of 5.6 liters per minute from each sample tube, while pumping through 150 meters of 12.7 rnrn bore tubing, against a 4.5 meter head. A depth sensor transducer within the fish provides a top-side readout of the actual operating depth of the fish, while a remote reading temperature sensor provides a continuous display of the water temperature.

Technical ReportA self-powered pumping system for in situ extraction of particulate and dissolved materials from large volumes of seawater(Woods Hole Oceanographic Institution, 1982-02) Winget, Clifford L. ; Burke, John C. ; Schneider, David L. ; Mann, Don R.A pumping system has been developed for the in situ extraction of particles and of dissolved constituents from large volumes of seawater. The assembly consists of a battery-powered submersible pump, filters, and chemisorptive cartridges; it is entirely self-contained and has been used successfully on ship's hydrographic wire to depths as great as 5800 m. The pump is designed to operate at a maximum pressure drop of 66 cm of Hg; flow rates have varied from 1.3 to 5.1 liters/min. We have sampled volumes as large as 758 liters, and the measured battery drain suggests that volumes several times this could be pumped at any depth. The system is being used to study a variety of artificial radionuclides, but modifications of the filter or chemisorbent units would make it useful in many other geochemical applications.

Technical ReportTechnical progress report : advanced marine technology 1 August 1972 - 31 January 1973(Woods Hole Oceanographic Institution, 1973-06-01) Aldrich, Thomas C. ; Maxwell, Arthur Eugene ; Bowin, Carl O. ; Luyendyk, Bruce P. ; Phillips, Joseph D. ; Hess, Frederick R. ; Vine, Allyn C. ; Ballard, Robert D. ; Marquet, William M. ; Porter, David L. ; McCamis, Marvin J. ; Winget, Clifford L. ; von Herzen, Richard P. ; Williams, David L.The work sponsored by ARPA at Woods Hole Oceanographic Institution is having an impact on efforts by those not directly involved in the projects both within and without the Institution. The navigation system being developed for submersible/mother ship has been recognized as a very useful system by members of the Geology/Geophysics Department and the Department of Physical Oceanography. Each department is now developing their own system based on the work already completed by the Ocean Engineering Department under the ARPA contact. Through the ARPA contract ComPhibLant (specifically ComPhibRonTen) was shown some of the advantages of doing something new about small boat and heavy object handling at sea and this program is expected to have some direct effect upon methods they will use in the future. Although the project concerned with developing biological equipment for deep sea work has not continued as part of the ARPA program, the seed was succssfully sown and several items are being developed at the Institution under separate funding. All the projects continued at a fair pace but not without some problems. The Deep Sea Rock Drill had some minor setbacks during operations with ALVIN, and the Air-Sea System (Long Range Ech-Ranging) project was hampered by a faulty engine aboard the air craft. Summaries of progress are given immediately below and more detail is available in the individual reports further on.

Technical ReportSea duct : a deep-sea computer-controlled recirculating flume for the study of sea floor stability : final report(Woods Hole Oceanographic Institution, 1987-08) Winget, Clifford L. ; Nowell, Arthur R. M. ; Terry, William E. ; Gordan, Allan G.The Sea Duct Ocean-Bottom Laboratory is a computer controlled recirculating inverted flume for the in-situ study of sediment transport. It is designed to measure the sea floor response to controlled currents analogous to those generated by surface waves, tidal, or deep ocean storms. The external support frame is an equilateral triangle with sixteen foot sides. It is 12 feet high, has an air weight of 12,500 lbs., and a 2800 lb. submerged weight. Three lead acid battery packs located at the vertex of the triangle legs provide power for the recirculating water pumps, hydraulic power, and ancillary equipment. The inner rotatable structure consists of a 4 foot long by 2 foot wide open bottom windowed test section that is 9 inches high. It is connected to 30 feet of 8 inch tube configured as an elongated toroid. Above the test section is a traverse carriage with stereo camera, flash, and a laser Doppler velocimeter to measure fluid stresses. Internal flow velocities are controlled and can be ramped up to approximately 2 ft/sec providing shear stress sufficient to scour sand, silts, and fine clays. Water and sediment sampling devices obtain specimens from inside and outside the test section. This report consists of three sections. The first subdivision discusses the electro-mechanical systems and deployment- recovery techniques, while the second portion covers the microprocessor controller and its support equipment. The third section contains the appendices, which consists of program listings, schematics, system and deployment check-list, etc.

Technical ReportTechnical progress report : advanced marine technology 1 February 1972 - 31 July 1972(Woods Hole Oceanographic Institution, 1973-02-28) Aldrich, Thomas C. ; Maxwell, Arthur Eugene ; Ballard, Robert D. ; Bowin, Carl O. ; Luyendyk, Bruce P. ; McCamis, Marvin J. ; Phillips, Joseph D. ; Porter, David L. ; Vine, Allyn C. ; Teal, John M. ; Marquet, William M. ; Winget, Clifford L. ; von Herzen, Richard P. ; Williams, David L.The two extremes of the program in this six month period were the Submerged Navigation System which was demonstrated to be a successful field system, and the near Bottom Continuous Gravity System, which was priced out of the market by the acceleration characteristics of ALVIN. In all the other subjects discussed in summary immediately below and in more detail further on, satisfactory progress was made. Again aircraft scheduling has held up further work on the Air Sea Systems project, but there is definite hope for some aircraft tiem in the fall. The Development of Equipment for Deep Sea Biological Research has been terminiated as of the beginning of this report.

Technical ReportRecirculating sea water benthic chamber for the study of the biogeochemistry of petroleum components at the sediment water interface(Woods Hole Oceanographic Institution, 1978-12) Winget, Clifford L.The experimental benthic chamber was designed to conduct both laboratory and in situ investigations on the transport and degradation of petroleum type hydrocarbons at the sediment water interface, and to investigate the sediment/ water/organism interactions. In its basic form, it consists of a rectangular flume constructed of stainless steel tube, a windowed observation chamber, a variable velocity pumping system and its associated controls, battery packs, and interconnecting cables. The base of the observation chamber is a removable assembly, allowing the user to select either a closed rectangular box for laboratory use, or a mud grab bottom sampler configuration for in situ evaluation. For in situ use, the mud grab doors are opened, the device lowered until it contacts and settles into the bottom. The side walls of the mud grab, its jaws, and the observation chamber walls effectively seal the assembly into a closed recirculating sea water system that uses the bottom sediment as the controlled sample. Hydrocarbon, oxygen, or other materials may be used to spike the recirculating sea water or bottom sediment. Several instrumentation ports have been provided to allow monitoring of the internal system chemistry. The self-contained power pack is pressure compensated with gaseous carbon dioxide, providing a non-explosive atmosphere within the battery box compartment as well as the pump drive motor package. A five day, on-the-bottom, operational test indicated that the battery system would provide sufficient reserve power to operate the device for an extrapolated minimum of 10 days without serious degradation of the internal water flow within the system. On completion of the bottom program, the mud grab doors are pneumatically closed, retaining the sea water and sediment sample as a complete ecological test system that can be returned to the surface for additional evaluation.

Technical ReportParticulate matter sinking to the deep-sea floor at 2000 M in the Tongue of the Ocean, Bahamas, with a description of a new sedimentation trap(Woods Hole Oceanographic Institution, 1976-09) Wiebe, Peter H. ; Boyd, Steven H. ; Winget, Clifford L.A sedimentation trap for use just above the deep-sea floor was free-fallen to a depth of 2050 m in the Tongue of the Ocean canyon on January 3, 1974. On March 6, it was successfully recovered with the assistance of D.S.R.V. Alvin. The trap has a base 1 m square and a height of 30 cm. At the trap bottom are filters to retain falling particles. Two spring-powered sliding doors, each 1 m x 0.5 m, are used to close off the lower 2 cm of the trap during ascent to prevent disturbance of the particles collected on the filters. Total carbon on the filters as determined by high temperature combustion averaged 2301 mgC/m2 or an average on a daily basis of 36.5 mgC/m2. Similar filter aliquots were treated with cold phosphoric acid to eliminate the inorganic fraction. The resulting carbon values (X =: 5.7 mgC/m2/day) suggest 14% of the total carbon reaching the sea floor at 2000 m in this area is organic in origin. Fecal material is one readily identifiable component of the material contributing to the organic fraction. Counts of fecal pellets resulted in an estimate of an average of ~650 pellets/m2/day. Average pellet length was 241 μm and diameter was 109 μm. In laboratory experiments the pellets sank at rates varying from 50 m/day to 941 m/day (X at 5°C =159 m/day). Comparison of the sedimentation trap estimates of organic carbon input to the sea floor in this area with benthic energy requirements indicates that rapidly sinking small particulate matter could supply approximately 14% of the metabolic requirements of the benthos.
