180th meridian. A set of oceanographic stations along 180° 
will be occupied at the same time the PIONEER is occupying 
stations along 160 W. Her program after May will consist of 
underway ocean surveys south of the Aleutians and west of the 
PIONEER's area. 
NORTHWIND (CG) on the annual Bering Sea Patrol will 
concentrate her physical and biological (BCF) operations 
in the Bowers Bank area (52-55°N). Her post-Season opera- 
tions will include oceanographic work in cooperation with 
Oregon State University and the University of Washington 
and seismic work in cooperation with the University of 
Wisconsin, Lamont Geological Observatory, and others. 
There is a possibility that this work might be extended 
into the Laptev and Kara Seas. 
The MAURY and SERRANO (NOO) between January and May 
will be carrying out hydrographic and other oceanographic 
surveys in the Gulf of Siam to obtain information for 
nautical charts and sailing directions, and to supplement 
the existing oceanographic knowledge of the area. SERRANO 
will spend about half of this time in the Indian Ocean doing 
heat flow measurements, standard oceanographic stations, 
and chemical, biological, meteorological and sea and swell 
observations. In October the MAURY and SERRANO will con- 
duct hydrographic surveys and limited additional oceano- 
graphic operations in the South China Sea, and en route
