at oceanographic stations and underway using high-speed 
sampling devices. 
3. Collections of larger invertebrates, fish juveniles 
and adults (mid-water trawls, night lights, etc.) - 
at oceanographic stations. 
4, Standardized observation and reporting of sightings 
of fish schools, sea birds, and aquatic mammals - 
underway and at oceanographic stations. 
5. Routine reporting of other natural and unusual phe- 
nomena (discolored water, mass mortalities, aggregation 
of organisms in relation to oceanic fronts or current 
boundaries, etc.) - underway and at oceanographic 
stations.
