Resource Assessment. The conversion utilized computer programs previously
developed for this purpose during OCSEAP RU608 - Kodiak Shelf
Holozooplankton Distribution and OCSEAP RU623 - North Aleutian Shelf Sea
Otter contracts. The converted data were put onto a magnetic tape at
Mellonics Information Center, Canoga Park, California, and the final
data product tape was then submitted to the OCSEAP Project Data Manager.
2.4 Data Analysis
Larval Crab. The crab larvae were initially described with a set
of summary tables and density maps by stage and cruise. Seven subareas
(strata) were selected for statistical comparison of areal results.
These areas were shown in Figure 2.4-1, and are a modification of
sampling strata defined by Armstrong, et al. (1983b) for analyses of
data collected 1976-1982.
The second statistical treatment was a multiple correlation analysis,
producing a correlation matrix between all of the included variables,
after which multiple linear regression was run on selected variables.
Prior to statistical treatment, the data were tested for normality, and
as they were not normally distributed, the data were log-transformed in
order to obtain valid statistical results. For larvae, the initial list
of variables included temperature and salinity at five and 10 meters
depth, time of day, time of year, station position, bottom depth and
maximum depth of tow. Multiple correlation analysis was selected as
the initial statistical treatment because it is a mathematically
succinct method of determining the relative magnitude of different
interactions within a large set of variables. In addition to the
statistical analysis of relative abundance and apparent distribution, a
limited analysis was performed on the Tucker trawl and neuston net
samples to test for the presence of larval diel vertical stratification.
Post-larval Crab.
Biological information collected for post-larval red
king crabs included carapace length, weight, sex, shell condition and
