Popis

Intertidal organism, habitat, fish survey, fishing duration, and other data were collected from the Outer Kenai Peninsula from the HUMDINGER as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were collected by Dames and Moore Inc. from 30 July 1975 to 31 August 1976. Data were processed by NODC to NODC standards F030 Intertidal Organism and Habitat format and F123 Fish/Shellfish Surveys format. Full format descriptions are available from the NODC homepage at www.nodc.noaa.gov/. An analog file for this accession is located at NODC in Silver Spring, MD. The F030 format contains data from field sampling of marine organisms in intertidal or subtidal habitats. The data are collected to provide information about species abundance and distribution. Data from each observation may include: cruise and station information such as vessel name, senior scientist, position, date, and time; environmental conditions such as surface temperature and salinity, wind speed and direction, and sea state; sediment and habitat descriptors; and species identification and organism counts and measurements. Data may be reported for either individual or composite samples. A text record is available for reporting comments. The F123 format is used for data from field sampling of marine fish and shellfish. The data derive from analysis of midwater or bottom tow catches and provide information on population density and distribution. Cruise information, position, date, time, gear type, fishing distance and duration, and number of hauls are reported for each survey. Environmental data may include meteorological conditions, surface and bottom temperature and salinity, and current direction and speed. Bottom trawl or other gear dimensions and characteristics are also reported. Catch statistics (e.g., weight, volume, number of fish per unit volume) may be reported for both total haul and for individual species. Biological characteristics of selected specimens, predator/ prey information (from stomach contents analysis), and growth data may also be included. A text record is available for comments.
