| 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 |
number(8,0) |
A unique five-digit number assigned to the observer for the length of their
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 |
date |
The date of gear retrieval in Alaska Local Time; for trawls, the time 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. This table does not include “no fishing” days. |
| MM_SPECIES |
varchar2(2) |
A two-digit alpha code representing a marine mammal species. NORPAC.MAMMAL_CODES provides the definitions. |
| SEX |
varchar2(1) |
A one-digit alpha code indicating the sex of one of the individual marine
mammals of a particular species involved in the interaction: M = male, F = female, U = unknown. |
| SPECIMEN_NUMBER |
number(2,0) |
A unique number assigned to identify a single specimen within the group of
marine mammals of a particular species involved in the interaction. |
| INTERACTION_NUMBER |
number(5,0) |
An observer-assigned number for each marine mammal interaction noted for a
particular cruise/vessel. The first interaction is assigned the number 1 and consecutive numbers to
the following interactions. Each interaction must have a different code even if the interaction is by the
same individual mammal. For example, two separate records, interaction codes, and interaction numbers would
be documented for an animal that was feeding on catch and then was deterred by the vessel. |
| STANDARD_LENGTH |
number(3,0) |
A standard length (cm) measurement taken on pinnipeds, i.e., the straight-line
distance from the snout to the tip of the tail flesh. |
| CURVILINEAR_LENGTH |
number(3,0) |
A curvilinear length measurement in cm that can be taken on all marine mammals,
i.e., the shortest surface distance from the snout to the tip of the tail flesh on the unskinned body. |
| TOOTH_TAKEN |
varchar2(1) |
A one-digit alpha code indicating whether or not the observer was able to collect a tooth or snout from the marine mammal, where: Y = Yes; N = No. |
| PHOTO_TAKEN |
varchar2(1) |
A one-digit alpha code indicating whether or not the observer took a photo of the marine mammal, where: Y = Yes; N = No. |
| TISSUE |
varchar2(1) |
A one-digit alpha code indicating whether or not a tissue sample was taken from the marine mammal, where: Y = Yes; N = No. |
| AGE |
number(4,1) |
Age (in years) of pinniped involved in the interaction, determined by the
National Marine Mammal Laboratory from teeth collected by observers. |
| AGE_AVERAGED |
varchar2(1) |
A one-digit alpha code indicating whether the age was estimated (Y) or precise (N)
based on the difficulty of identifying and enumerating the annual growth lines in the tooth structure. |
| COMMENTS |
varchar2(2000) |
Comments about this individual marine mammal interaction from the observer and
from the staff from the National Marine Mammal Laboratory. |
| DATE_OF_ENTRY |
date |
Date that data entered the database system. |
| LAST_EDITOR |
varchar2(12) |
Observer program editor who last made changes to the record. |
| SEQUENCE_NUMBER |
number(5,0) |
For use by National Marine Mammal Laboratory. |
| YEAR |
number(4,0) |
A four-digit number identifying the year in which the gear retrieval of the haul
began. |
| MM_INTERACTION |
number(2,0) |
A two-digit numeric code identifying what type of interaction occurred and
(if known) the viability of the marine mammal after the interaction. NORPAC.MAMMAL_INTERACTION provides the definitions. |
| CREATE_DATE |
date |
Date record was inputted into database. |
| CREATED_BY |
varchar2(30) |
Person who loaded data into database. |
| LAST_UPDATE_DATE |
date |
Date data record was last altered. First entered in December 2003. |
| LAST_UPDATED_BY |
varchar2(30) |
Person who last altered data record. First entered in December 2003. |
| ATLAS_VERSION |
number(4,0) |
Version number of the 'at-sea' software used for data input and transmission.
First entered in 2004. |
