Zooplankton counts were collected via Tucker trawl surveys in the coastal waters of the Gulf of Alaska from 2001 to 2003. Surveys were conducted aboard the F/V Great Pacific in 2001-2002 and NOAA Ship Miller Freeman in 2003, sampling transects from nearshore to beyond the 200-meter shelf break. Plankton samples were preserved in formalin onboard and analyzed in a laboratory.
Use Cases
- Analyze zooplankton community composition based on counts from Tucker trawl samples.
- Study spatial distribution patterns across continental shelf transects.
- Model changes in plankton abundance over the 2001-2003 time period.
- Estimate water filtration volumes based on flow meter data mentioned in the description.
Strengths
- Sampling occurred over a three-year period from 2001 to 2003.
- Transects extended from nearshore to oceanic waters beyond the 200-meter shelf break.
- Plankton samples were preserved in 5% formalin onboard, likely ensuring sample integrity.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2003-08-07 23:59:59.999000; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
