Zooplankton samples were collected via oblique bongo net tows to a depth of 20 meters in the coastal waters of the Gulf of Alaska. The survey occurred aboard the F/V Great Pacific from October 19 to November 8, 2004, using nets with 335 and 505 micron mesh. Samples were preserved in formalin onboard and analyzed in a laboratory.
Use Cases
- Analyze zooplankton community composition based on counts from bongo net hauls.
- Study spatial distribution patterns across continental shelf transects perpendicular to shore.
- Model relationships between plankton abundance and water depth up to 20 meters.
- Compare sampling efficiency between nets with 335 and 505 micron mesh sizes.
Strengths
- Sampling methodology is explicitly described, including oblique tows to 20 meters depth.
- Survey has a defined temporal range from October 19 to November 8, 2004.
- Geographic scope is specified as transects perpendicular to shore across the Gulf of Alaska shelf.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2004-11-12 23:59:59.999000; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
