currents. Investigations now in progress include 

 marine fouling, bioluminescence, underwater 

 visibility, and bottom pressine fluctuations. 



Radioisotopic Oceanography — This project will 

 be carried out in cooperation with the Atomic 

 Energy Commission. The research will utilize 

 both natural and radioisotopes which are arti- 

 ficially introduced into the sea as tracers of ocean 

 water circulation, mixing, and other dynamic 

 oceanographic processes. Direct shipboard mea- 

 surement will be taken using submersible de- 

 tectors, and various types of marine environ- 

 mental samples will be collected for laboratory 

 analysis ashore. 



During the summer of 1965, samples of air, 

 sea water, surface plankton, and bottom sediment 

 were collected and returned for laboratory analysis 

 of their radioisotope constituents. These samples 

 will be utilized to study basic oceanographic 

 features as revealed by the long-term transport 

 and deposition of artificial radionuclides. 



Joint research with the Naval Ordnance Labo- 

 ratory on the in situ gamma radiation spectra 

 is being conducted on a continuing basis. 



Spacecraft Oceanography — This project will in- 

 vestigate and evaluate the possible application of 

 remote sensors and spacecraft techniques to 

 obtain oceanographic data, and to develop in- 

 terpretation and display procedines to permit a 

 useful application of these data. 



Experiments are planned to test and assess the 

 employment of remote sensors, such as infrared, 

 microwave, radar, and photography, for the 

 purposes of providing required information on 

 oceanographic features and phenomena such as 

 waves, thermal conditions, ice, icebergs, shoals, 

 etc. An experiment will be conducted at Goose 

 Bay, Labrador, employing remote sensors aboard 

 aircraft to obtain ice data which will be correlated 

 with measurements obtained by ground parties. 

 Another experiment employing airborne remote 

 sensors will be conducted in the vicinity of ARGUS 

 ISLAND, Bermuda, to evaluate scatterometer data 

 in relation to wave height measurements obtained 

 by other means. Additional experiments will be 

 sponsored during FY 1967 involving spacecraft, 

 aircraft, and surface techniques to obtain data 

 for evaluating instruments and techniques as they 

 apply to providing various types of oceanographic 

 data. 



Navy ^crf — This project will collect detailed 

 three-dimensional oceanographic data over an 

 extended jaeriod of time from a one degree square 

 in the North Atlantic Ocean. 



To collect these data, eight oceanographic 

 buoys of the Antisubmarine Warfare Environ- 

 mental Prediction System (ASWEPS) program 

 will be utilized. Each buoy will telemeter informa- 

 tion from a series of 25 temperature sensors 

 located between the surface and a depth of 1 ,000 

 feet over a period of six months. They will also 

 report wind speed and direction, air temperature, 

 and barometric pressure. By locating the buoys 

 in a grid network in a limited area, it is possible 

 to establish the nucleus of a three-dimensional 

 measurement system for ocean dynamics studies 

 while at the same time accomplishing necessary 

 test and evaluation of the instruments themselves. 

 In addition, at least three strings of current 

 meters will be placed within the area to obtain 

 measurements over a period of at least one month. 

 Data will also be collected in the area from re- 

 search vessels. 



O^Apr— Certain other efforts are being conducted 

 on a modest basis. These include: a program to 

 improve capability for rapid retrieval and display 

 of textual and graphic oceanographic and hydro- 

 graphic information; a study to develop tech- 

 niques and equipment to evaluate, compile, and 

 reproduce data required for navigation charts 

 and publications; and a study to develop improved 

 techniques for determining the earth's gravity 

 field at sea. 



Navy Laboratory Ship Operations 



FY 1965-12,000,000 

 FY 1966-12,500,000 

 FY 1967-13,062,000 



The Naval Oceanographic Office operates 

 AGOR research \essels to meet the requirements 

 of all Navy laboratories conducting the programs 

 described above. A total of $3,062,000 has been 

 included in the Navy ICO research budget to fund 

 the operations of these ships in FY 1967.
