| CRUISE |
number(4,0) |
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. |
| VESSEL |
varchar2(4) |
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. |
| DT |
date |
Similar to NORPAC.DOMESTIC_SPCOMP.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). |
| YEAR |
number(4,0) |
A four-digit number identifying the year in which the gear retrieval of the haul began. |
| HAUL |
number(3,0) |
A unique number which identifies a specific occurrence of net, pot, or longline fishing effort. This table does not include “no fishing” days. |
| SPECIES
|
number(3,0) |
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). |
| SEX |
varchar2(1) |
A one-digit alpha code indicating the sex of the organism. F = female, M = male, U = unknown.
|
| WEIGHT_SAMPLED |
number(10,2) |
The total weight in kilograms of all of the sampled species in the sample.
|
| NUMBER_IN_SAMPLE |
number(7,0) |
The number (count) of the specified species which occurred within the sample.
|
| WEIGHT_IN_SAMPLE |
number(10,2) |
The total weight in kilograms of the specified species which occurred within the sample. |
| NUMBER_OF_POTS_SAMPLED |
number(5,0) |
The number of pots in the set that were sampled for species composition.
|
| NUMBER_OF_SKATES_SAMPLED |
number(5,0) |
The number of hachi (skates) that were sampled for species composition.
|
| SPECIES_HAUL_NUMBER |
number(8,0) |
The estimated number of the specified species in the entire haul extrapolated from the sample. |
| SPECIES_HAUL_WEIGHT |
number(13,2) |
The estimated weight in kilograms of the specified species in the entire haul extrapolated from the sample.
|
| EXTRAPOLATION_TYPE |
number(1,0) |
A one-digit code associated with the procedure used to extrapolate the NUMBER_IN_SAMPLE and WEIGHT_IN_SAMPLE to SPECIES_HAUL_NUMBER and SPECIES_HAUL_WEIGHT. NORPAC.FOREIGN_EXTRAPOLATION provides a description of the codes.
|
| HAUL_JOIN |
number(6,0) |
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. |
