OCEANOGRAPHIC AND UNDERWATER ACOUSTICS RESEARCH.

Abstract

Geophysical investigations were carried out aboard R/V CHAIN in the Indian Ocean, the Mediterranean Sea, and the North Atlantic Ocean. Observations underway were continuous seismic profiling, gravity, magnetic, and echo sounding measurements. At stations rocks were dredged, cores were taken (about 10 meters long, photographic montages of the sea floor were made, and the sound velocity of the water was measured as a function of depth. Progress is being made in filtering and correlation techniques for seismic profiling, while seismic receiving arrays were improved to make them quieter. The analysis of internal wave data is continuing, but further observations at sea will be required in order to fully understand the mechanism of propagation. A new thermistor string intended to replace and improve upon the original thermistor chain was the principal new instrumental development.
