Item Identification

Title: Table: ATL_SAMPLE
Short Name: ATL_SAMPLE
Status: Completed
Abstract:

This entity represents the individual samples of a type that may be collected from an observed haul. It is header information for species composition. If there are rare species present in sample and there exist multiple predominant species, a recursive subsample or subsamples may be created. The sum of the weights of the subsamples must be less than or equal to the parent sample.

Entity Information

Entity Type: Data Table
Active Version?: Yes
Schema Name: NORPAC
Description:

This entity represents the individual samples of a type that may be collected from an observed haul. It does not currently map to any Norpac table, but is header information for species composition.If there are rare species present in sample and there exist multiple predominant species, a recursive subsample or subsamples may be created. The sum of the weights of the subsamples must be less than or equal to the parent sample.

Data Attributes

Attribute Summary

Rubric Score Primary Key? Name Type Description
100
cruise1 NUMBER Sequence generated by Norpac and supplied to the observer as an unique identifier for an observer cruise record.
100
Primary Key CRUISE NUMBER Sequence generated by Norpac and supplied to the observer as an unique identifier for an observer cruise record.
100
Primary Key SAMPLE_SEQ NUMBER Sequence generated unique identifier of a sample
100
PARENT_SAMPLE_SEQ NUMBER Sequence generated unique identifier of a sample
100
SAMPLE_NUMBER NUMBER Sequence within either haul or offload parent. This value is auto-generated but not necessarily unique.
100
OFFLOAD_SEQ NUMBER Sequence generated unique identifier for an offload record
100
HAUL_SEQ NUMBER Sequence generated unique identifier for a haul record
100
COMBINED_SAMPLE_FLAG VARCHAR2 Identifies whether unique samples within a haul have been aggregated together.
100
PRESORTED_FLAG VARCHAR2 This flag indicates that child species composition records did not come from and unsorted catch. Generally if a single large animal was removed before sampling began and so was not available for inclusion in any random sample
100
TOTAL_SAMPLE_WEIGHT NUMBER Total weight in kg of this sample.
100
SAMPLE_HOOKS_POTS NUMBER Number of hooks or pots sampled.
100
Primary Key PERMIT VARCHAR2 Unique Code identifying a vessel or Processor - inherited from the NORPAC data set and created by the RAM division in Juneau
100
SPECIES_COMP_IN_SAMPLE VARCHAR2 This flag indicates that fish were found or were absent in this sample - in the latter case composition records are not permitted and the sample is ignored for extrapolations.
100
SAMPLE_DESIGN_FLAG VARCHAR2 Identifies this sample as complying (Y) or differing (N) from the protocol declared at the haul level.
100
NUMBER_OF_SEGMENTS_SAMPLED NUMBER The number of segments (skates, racks) of hooks which went into this sample. This number may be fractional.
100
SAMPLE_HOOKS_OVERIDE_FLAG VARCHAR2 This flag identifies an observer overide of the computed sample hooks - pots variable. The setting of the flag to Y will prohibit the automatic computation of sample hooks-pots from haul-hook-count * number-of-segments-sampled.
