components, and material pertaining to existing and proposed weapons, 

 principally missiles and underwater ordnance. It investigates bottom- 

 water pressure fluctuations in minable waters, optical properties of 

 the ocean, shallow-water sound propagation, acoustic output of explo- 

 sive charges, and acoustic area techniques. In 1968-72 it conducted 

 a Deep Ocean Optical Measurement (DOOM) project in the North Atlantic, 

 Caribbean, and Mediterranean. 



394. NAVAL POSTGRADUATE SCHOOL: NPS 



NFS or NPGS is at Monterey, Calif, and specializes in education 

 pertaining to needs of the Department of the Navy, especially in 

 oceanography. 



395. NAVAL SEA SYSTEMS COMMAND: NSSC 



NSSC is responsible for much of the deep ocean research and 

 engineering studies made by the Navy. Its projects include Deep 

 Submergence Systems Project (DSSP) and Acoustic Performance Prediction 

 (APP). It includes an Environmental Diving Unit (EDU) and sponsors 

 the Diving Information Center (DIC). 



396. NAVAL SHIP RESEARCH AND DEVELOPMENT CENTER: NSRDC 



Also known as the David W. Taylor Naval Research and Develop- 

 ment Center, NSRDC is concerned with the development of naval ship 

 and aviation systems. It gathers data on environmental conditions 

 that affect ship construction and is concerned with pollution abate- 

 ment aboard ships. It is responsible for the David Taylor Model 

 Basin (DTMB). 



397. NAVAL UNDERWATER SYSTEMS CENTER: NUSC 



NUSC is the principal center in the Navy for research in under- 

 water weapons and undersea warfare. It was formed in 1970 by a merger 

 of the Naval Underwater Sound Laboratory (NUSL or USNUSL) and the 

 Navy Underwater Weapons Research and Engineering Station (NUWRES). 

 Its studies include physical, biological, and geological oceanography, 

 internal waves as they relate to acoustic system design, air-sea 

 interface, ocean turbulence, variability of shallow water as a weapons 

 environment, ambient noise in the Arctic, and oceanography of under- 

 water test ranges. In 1970 it initiated a Moored Acoustic Buoy Sys- 

 tem (MABS), a remote subsurface moored self-recording data acquisition 

 system. It supports the Sonar In-Situ Mode Assessment System (SIMAS). 

 In cooperation with the Lamont Doherty Geological Observatory (LDGO), 

 it sponsored the Major Investigation for Low-Frequency Ocean Bottom 

 Loss Experiments (MAINLOBE). It is responsible for the Block Island- 

 Fisher Island Range (BIFI) and makes oceanographic surveys of the area. 



398. OFFICE OF NAVAL RESEARCH: ONR 



ONR Plans and coordinates research programs of naval relevance 

 throughout the Department of the Navy and executes contracts for doing 

 research at educational and other nonprofit institutions. Its field 

 activities include the Naval Research Laboratory (NRL); Naval Biosci- 

 ences Laboratory (NBL); Naval Arctic Research Laboratory (NARL); and 

 Naval Ocean Research and Development Activity (NORDA). 



NRL was responsible for the Light Behind the Camera (LIBEC) system, 

 which permits photographs of the deep bottom to be taken at greater 

 ranges than before; LIBEC was used during Project FAMOUS to photograph 

 the Mid-Atlantic Ridge. It developed the Over-The-Horizon (OTH) radar 

 for remote observations of sea state at long range and the Synthetic 

 Aperature Radar (SAR) used to detect and map ocean current boundaries. 

 In cooperation with NOAA and the Institute for Telecommunications
