Data Attributes

Attribute Summary

Score Req'd? PKey? » Name Data Storage Type Description
100 Yes No CRUISE NUMBER A unique four-digit number to represent each occasion that an observer was aboard a different fishing vessel during deployment. Cruise number is associated with all of the data collected by the observer aboard the vessel.
100 Yes No VESSEL VARCHAR2 A unique, four-digit, alpha-numeric code identifying each vessel that contracts for observer coverage. All vessel codes begin with the alpha code B, followed by a three-digit number.
100 Yes No DT DATE Similar to NORPAC.DOMESTIC_HAUL.HAUL_DATE, this is the date in Greenwich Mean Time. Format is stored in the database as DD-MON-YY format (i.e., 15-MAR-86), and displayed as MM/DD/YYYY HH:MI:SS (i.e., 3/15/86 00:00:00).
100 Yes No YEAR NUMBER A four-digit number identifying the year in which the gear retrieval of the haul began.
100 Yes No HAUL NUMBER A unique number which identifies a specific occurrence of net, pot, or longline fishing effort. This table does not include "no fishing" days.
100 Yes Yes SPECIES NUMBER A three-digit numeric code representing a marine species. This code is associated with species name in NORPAC.DOMESTIC_SPECIES (using the column name SPECIES_NO in place of SPECIES).
100 Yes No LENGTH_TAKEN VARCHAR2 A one-digit numeric code. 1 - Yes, lengths were taken. 2 - No, lengths were not taken. (Other responses in this field are 3, 4, and null. The meaning of these responses are unknown and are likely erroneous.)
100 No No PERCENT_SPAWN_FEMALES NUMBER The percentage of female pollock observed that were spawners.
100 Yes No AGE_STRUCTURE_TAKEN VARCHAR2 A one-digit numeric code. 1 - Yes, age structures were taken. 2 - No, age structures were not taken. (The other response in this field was a null value. Likely, the observer neglected to fill in this field.)
100 Yes No FEEDING_OBSERVED VARCHAR2 A one-digit numeric code. 1 - Yes, feeding was observed. 2 - No, feeding was not observed. (The other responses are 3 and null. The meaning of these responses are unknown and are likely erroneous.)
100 No No FILENAME VARCHAR2 The original filename on the Burroughs computer system from which this data record came.
100 Yes Yes HAUL_JOIN NUMBER An assigned, unique number (up to 6 digits) used to link records in this table back to a single haul record in the NORPAC.FOREIGN_HAUL table.
