Agency plans to continue its exploratory develop- 

 ment work in ocean-bottom seismology. It is 

 expected that the main effort will be directed 

 toward testing of the shore monitored, cable 

 connected, ocean-bottom seismograph station 

 concept. However, some attention will be given 

 to the redesign of existing prototype untethered 

 devices to improve the reliability of instrument 

 packages and to enhance successful recovery of 

 untethered ocean-bottom seismographic systems. 



The automatic hydrographic sur\'ey system 

 has been designed to automate the collection and 

 storage of hydrographic, oceanographic, geo- 

 physical, and meteorological data on deep-ocean 

 survey vessels. The system includes real time 

 computer control of x-y plotters. In FY 1967 this 

 system will be installed as an integral part of 

 C&GS sin-vey vessels. 



A satellite navigation system has been installed 

 on a survey vessel and from operational evalua- 

 tions to date the system looks promising. An 

 additional unit and finther system evaluation is 

 planned for FY 1967.

The Coast and Geodetic Survey has increased 

 the automation in its instrument and data handling 

 systems by the development of the new ODESSA 

 buoy system for ocean survey programs. A multi- 

 ple chain of sensors meastnes conductivity, 

 temperature, depth, current speed, and current 

 direction. Digitized data is recorded in the buoy 

 and is telemetered to either a ship or shore sation. 

 These monitoring stations are capable of simul- 

 taneously recording the transmissions of several 

 buoys. 



The bottom-mounted deep sea tide gauge 

 system originally tested at 1,000 feet, will be in- 

 stalled in 5,000-foot depths in FY 1967. 



The new tidal current meter system, developed 

 for use with the ODESSA buoy system, makes it 

 possible to increase the number of stations at 

 which ciurent data can be measiued from a single 

 ship. The ODESSA data format is designed for 

 automatic processing. 



The tmderwater stable platform is a buoy held 

 thirty meters below the sea surface by a three-wire 

 moor to minimize rotation and vertical and hori- 

 zontal motions. It has been successfully placed in 

 water 2,000 feet deep, and additional installations 

 are planned for FY 1967.

SAIL is working to improve methods of data 

 acquisition at the sea air interface — the gradient 

 level of the atmosphere and the mixed layer of 

 the ocean. Work is in progress on such indirect 

 sensing techniques as microwave and visible light 

 refraction and radiation. 



The i^lanetary boundary layer sensor system 

 measures temperature, humidity, wind velocity 

 and direction, and radiation from the sea surface 

 to the gradient level (sea level to 3,000 ft. above). 

 The infrared sensors for measuring sea surface 

 temperature will be used aboard an ESSA research 

 aircraft. 



Engineering development will be carried out on 

 the ship board data acquisition and processing 

 systems for measuring variables of surface en- 

 vironment. A new microwave sensor will provide 

 an indirect techniqtie for the measurement of 

 himiidity.
