Table: FOREIGN_HAUL

If a U. S. vessel delivered the haul to a vessel carrying an observer, this field contains the A unique four-digit number assigned to the observer for the length of their contract period. This number alone identifies and groups a set of observer information.

NORPAC.FOREIGN_FISHING_OPERATI

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.

Refers to more than one entity

A four-digit number identifying the year in which the gear retrieval of the haul began or in which the noon position occurred.

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).

A unique number which identifies a specific occurrence of net, pot, or longline fishing effort. Additionally, a day in which a vessel was on grounds is occasionally recorded with a haul number of 0 (zero) if no codend, longline set, or pot group retrievals were begun.

A one-digit alpha code that indicates what type of fishing activity occurred at the latitude and longitude recorded. R = the position of the vessel when the retrieval of the haul/set was begun, D = the position of the vessel when a delivery was completed to a mothership, N = the position of the vessel at noon (Greenwich Mean Time) on a day when no fishing took place and the vessel was not in port, S = the position of the vessel when gear began being set.

A four-digit number recorded in degrees and minutes north. The geographical position associated with the LOCATION_ID.

Direction of longitude, E = east and W = west of the 180th meridian.

A five-digit number recorded in degrees and minutes west of 0 degrees. Any position west of 180 degrees is stored as a value greater than 18000, e.g., 170 degrees east longitude = 19000. The geographical position associated with the LOCATION_ID.

The average fishing depth at which fishing took place, in meters.

The average of the lowest points on the ocean floor where fishing took place (in meters). This is only recorded for joint venture vessels.

The time when the net reached fishing depth (in Greenwich Mean Time). Use DURATION and NETS_OFF_BOTTOM and subtract to determine the date.

The time when the net began to be retrieved from fishing depth (in Greenwich Mean Time). The date is the same date as DT.

For longline or pot vessels, the time interval from the time that the first part of the line/pot-group was set until the time that the last of the line/pot-group was retrieved (also known as soak time). For trawlers, duration is the length of time during which the net was at fishing level. Duration is the difference between the NETS_ON_BOTTOM and the NETS_OFF_BOTTOM. Recorded in minutes.

Is only not null for vessels where fishing information is recorded as a daily event. Prior to 1977, all data were compiled as a daily event and are associated with a Noon Position. When HAUL=0, then NUMBER_OF_TOWS is the number of tows that occurred that day. After 1976, only true motherships and, through 1983, joint venture motherships were combined on a daily basis. In 1988, two cruises (2943 B002 and 2977 B002) were the exception to this rule. The observers made a mistake and the data were combined by day. For an unknown reason, there are also 17 records where HAUL=0, NUMBER_OF_TOWS>0, and OFFICIAL_TOTAL_CATCH is null.

Final estimate of catch weight (MT) for the set or haul, made by vessel personnel, includes both retained and discarded species, and is recorded to the nearest one-hundredth of a metric ton. If original_ships_estimate is not null, official_total_catch is the original_ships_estimate adjusted by the observer to include prohibited species and non-allocated species. If NUMBER_OF_TOWS>0, then OFFICIAL_TOTAL_CATCH is the total catch for the day.

Average towing speed of the vessel during the tow, recorded to the tenth of a knot. Recorded from the vessel logbook.

A one-digit numeric code identifying the weather conditions during the fishing operation. NORPAC.FOREIGN_WEATHER provides a description of the codes.

NORPAC.FOREIGN_WEATHER

A one-digit numeric code identifying the sea conditions during the fishing operation. NORPAC.FOREIGN_SEA provides a description of the codes.

NORPAC.FOREIGN_SEA

The temperature of the surface water in degrees Celsius.

The temperature of the water at fishing depth in degrees Celsius.

The time (Greenwich Mean Time) when the tow was delivered to the joint venture mothership. Recorded from vessel logs or observer observation.

The number of hachi (skates) for a single set.

The average number of hooks in a (hachi) skate.

Estimate of total catch for the set or haul made by the observer, recorded to the nearest one-hundredth of a metric ton. See observer instruction manuals for specific information on possible estimation methods.

Similar to NORPAC.DOMESTIC_HAUL.VESSEL_ESTIMATE, this is the initial estimate of the catch made by the vessel, recorded to one-hundredth of a metric ton.

If a U. S. vessel delivered the haul to a vessel carrying an observer, this field contains the Alaska Department of Fish and Game (ADF&G) vessel code number of the delivering vessel. NORPAC.FOREIGN_CATCHER_BOAT provides the names of the catcher boats and the coast guard numbers associated with the codes.

NORPAC.FOREIGN_CATCHER_BOAT

For pot vessels, the total number of pots in a set, i.e., the number of pots or group of pots in the set that were retrieved.

This field is null.

An assigned, unique number (up to 6 digits) that uniquely identifies each haul/set associated with vessel data. NORPAC.FOREIGN_HAUL.HAUL_JOIN links a single haul record to records in many of the foreign tables.

A three-digit number representing NORPAC database management subareas which, in most cases, are similar to NPFMC management areas. NORPAC.AREA links latitude and longitude to GENERIC_AREA (called GENERIC).

A one-digit numeric code indicating whether or not a haul was sampled for species composition: 0 = not sampled, 9 = sampled. If more than one observer was onboard the vessel, there is no way of knowing which observer sampled the haul..
