Zooplankton biomass displacement volumes sampled in the North Pacific Ocean from 1951-01-10 to 2015-05-01, as part of the California Cooperative Oceanic Fisheries Investigations (CalCOFI). Data were acquired from the NMFS-COPEPOD database and are available in both long and short formats. The accession includes HTML files for reconstructing the COPEPOD environment to search by platform, project, investigator, cruise, and taxa.
Use Cases
- Analyze seasonal variability in zooplankton biomass based on the multi-decade time series.
- Study inter-annual changes in zooplankton abundance based on the long-term sampling.
- Search and filter data by specific research cruises or investigators using the included HTML interface.
- Compare zooplankton biomass across different sampling platforms mentioned in the description.
Strengths
- Data spans a 64-year period from 1951 to 2015.
- Includes biomass data in both long and short formats as available in the COPEPOD program.
- Associated HTML files allow for data search by platform, project, investigator, cruise, and taxa.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2017-05-01 00:00:00; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
