Column Name |
Definition |
LATITUDE |
Start latitude of the haul in decimal degrees. |
LONGITUDE |
Start longitude of the haul in decimal degrees. |
STATION |
RACE database station id. In the Eastern Bering Sea these stations have remained constant from the beginning of this time series. In the other regions sampling locations vary and are identified by the station grid cell in which the haul took place. |
STRATUM |
RACE database statistical area used for analyzing the data. Strata were designed using bathymetry and other measures of habitat. |
AREA_KM2 |
Stratum area in square kilometers. |
YEAR |
Four digit year. |
DATETIME |
Date and time of the start of the haul. |
KG/HA |
The quantity of a species caught is standardized by calculating kilograms caught per hectare (10,000 square meters) swept called catch per unit effort or weight CPUE. |
NO/HA |
The quantity of a species caught is standardized by calculating number of species caught per hectare (10,000 square meters) swept called catch per unit effort or number CPUE. |
NAME |
Selection category listed in the dropdown menu composed
of either the common name of a species or the name of a miscellaneous group. Miscellaneous
groups are collections of species which were not caught every year or not separately
identified every year. |
COMMON |
Common name of a species. |
SCIENTIFIC |
Taxonomic name of a species. |
SID |
RACE database species id number. |
RANK |
The species catch has been classified into three equal
intervals over all years by the weight CPUE (KG/HA). This allows comparison a species abundance
between stations and between years. Rank = 1 is low relative abundance. Rank = 3 is high
relative abundance. |
BOT_DEPTH |
Bottom depth in meters. |
BOT_TEMP |
Bottom temperature in degrees Celsius. |
SURF_TEMP |
Surface temperature in degrees Celsius. |
CRUISE |
RACE database cruise id number. |
VESSEL |
RACE database vessel id number. |
HAUL |
RACE database haul id number. |
