Popis
Herring spawning and other data were collected from aircraft from the Bering Sea as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were collected from 07 May 1977 to 28 October 1978 by the Alaska State Department of Fish and Game - Kodiak. Data were processed by NODC to the NODC standard F057 Herring Spawning format. Full format descriptions is available from the NODC homepage at www.nodc.noaa.gov/. An analog file for this accession is available from NODC user services. The F057 format contains data from aircraft surveys of herring schools. These data were collected to provide information on herring population density and distribution. Start date and time, start and end positions, and aircraft type, altitude and airspeed were reported for each survey. Surveys were conducted for preassigned areas; mid-point positions of census areas were reported. environmental information may include meteorological conditions, sea state, air roughness and water clarity. Census data include species identification, school position and activity, school size index and number of schools sighted. Predominant beach type, biota type and escarpment type may also be indicated.
