| HAUL_JOIN |
number(9,0) |
An assigned, unique number (up to nine digits) that uniquely identifies each
haul/set associated with vessel data. NORPAC.DOMESTIC_HAUL.HAUL_JOIN links a single haul record to records in the domestic
tables for data on species composition, length, age, marine mammal, and viability interactions. |
| CRUISE |

contract period. This number alone identifies and groups a set of observer information. |
| 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 A, followed by a three-digit
number, or for plants, the codes begin with the alpha code P, followed by a three-digit number. |
| HAUL_DATE |

The date of gear retrieval in Alaska Local Time; for trawls, the date that the
retrieval of the net began, i.e., when the winding of the cables began, and the net left the fishing level.
Format is stored in the database as DD-MON-YY format (i.e., 15-MAR-96), and displayed as YYMMDD HH:MI:SS
(i.e., 960315 00:00:00). |
| HAUL |
number(4,0) |
A unique number which identifies a specific occurrence of net, pot, longline
or jig 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, pot group retrievals or jigging sessions were begun. |

the vessel, where: 1 = non-pelagic trawl, 2 = pelagic trawl, 3 = unknown or mixed trawl, 4 = pair trawl,
5 = shrimp trawl, 6 = pot or trap, 7 = jig, 8 = longline, 9 = gill net, and 10 = Scottish seine. |
| PERFORMANCE |
number(2,0) |
A one-digit numeric code that indicates how well the fishing device operated,
where: 1 = no problem, 2 = crab pot in haul, 3 = net hung up, 4 = ripped net, 5 =an unspecified problem,
6 = groundline cut or lost one of following: codend, entire net, longline, jig, or pot gear,

| VESSEL_TYPE |
number(2,0) |
A one-digit numeric code that indicates whether the vessel processes fish or
delivers it to a processing plant where: 1 = a catcher processor vessel, 2 = a mothership or a ship
that receives unsorted codends from other vessels, 3 = a catcher only vessel that delivers unprocessed fish
to a shoreside or floating plant or vessel, 4 = a mothership that receives sorted codends, 5 = a vessel
that sells the majority of their catch over the side to other fishing vessels who will utilize the fish
for bait, 6 = vessels that discard all catch from a haul; would be used for codend dumping of an entire
haul (added January 2004). |
| LOCATION |
varchar2(1) |
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
began, D = the position of the vessel when a delivery was completed to a mothership, N = the
position of the vessel at noon (Alaska Local Time) on a day when no fishing took place and the vessel was
not in port, S = the position of the vessel when gear reached fishing depth and there was no other available
information about the haul/set. |
| LATITUDE |
number(5,0) |
A four-digit number recorded in degrees and minutes north. The geographical
position where the gear retrieval began, or, on days when no fishing occurred, the position of
the vessel at noon (Alaska Local Time), or, for a mothership receiving a delivery, the delivery location. |
| LONGITUDE |
number(5,0) |
A five-digit number recorded in degrees and minutes. The geographical position
where the gear retrieval began, or, on days when no fishing occurred, the position of the vessel
at noon (Alaska Local Time), or, for a mothership receiving a delivery, the delivery location. |
| LONGITUDE_CONVERTED |
number(5,0) |
A five-digit number recorded in degrees and minutes. For a longitude east (E) of the 0 degree longitude, the longitude is subtracted
from 359 degrees 60 minutes. Value is always positive. For example, if the longitude is 174 degrees,
46 minutes E, then the longitude_converted = (359 degrees, 60 minutes) - (174 degrees, 46 minutes)
= 185 degrees, 14 minutes. |
| E_W |
varchar2(1) |
A one-digit alpha code reflecting the raw data longitude of the gear retrieval
location, whether east ('E') or west ('W') of 180 degrees longitude. |
| DEPLOYMENT_DATE |
date |

that the net reached fishing depth. Format is stored in the database as DD-MON-YY format (i.e., 15-MAR-96),
and displayed as YYMMDD HH:MI:SS (i.e., 960315 00:00:00). |

position where the gear deployment occurred. |
| DEPLOYMENT_LONGITUDE_CONVERTED |
number(5,0) |
A five-digit number recorded in degrees and minutes. For a deployment_longitude east (E) of the 0 degree longitude, the longitude is
subtracted from 359 degrees 60 minutes. Value is always positive. For example, if the deployment_longitude
is 174 degrees, 46 minutes E, then the longitude_converted = (359 degrees, 60 minutes) - (174 degrees,
46 minutes) = 185 degrees, 14 minutes. |
| DEPLOYMENT_E_W |
varchar2(1) |
A one-digit alpha code reflecting the raw data longitude of the gear deployment
location, whether east ('E') or west ('W') of 180 degrees longitude. |
| FISHING_DEPTH_FATHOMS |
number(4,0) |
Not recorded for longliners or pot vessels. It should be noted that if the observer recorded the fishing_depth in meters,
the fishing_depth was converted to fathoms by the database and stored in this column. Therefore, if a data
user would like to compare pre-2004 depth data (which is only in fathoms) to post-2004 depth data (which is
in fathoms or meters), they could use only the fishing_depth_fathoms column for post-2004 data to ensure
that they are always looking at data in fathoms. |
| BOTTOM_DEPTH_FATHOMS |
number(5,0) |
BOTTOM_DEPTH is the only depth recorded for longliners and pot vessels. It should be noted that if the observer recorded the bottom_depth in meters, the
bottom_depth was converted to fathoms by the database and stored in this column. Therefore, if a data user
would like to compare pre-2004 depth data (which is only in fathoms) to post-2004 depth data (which is in
fathoms or meters), they could use only the bottom_depth_fathoms column for post-2004 data to ensure that
they are always looking at data in fathoms. |

ship in the NMFS fishing log of the vessel, recorded to one-hundredth of a metric ton. |

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 usually the difference between the DEPLOYMENT_DATE time and the RETRIEVAL_DATE time, but in some
cases, if the vessel lowered and raised the net several times during one haul, the duration can be less
