Chlorophyll and Phaeophytin Measurements in the NW Atlantic, 1978-1982

Chlorophyll and phaeophytin measurements collected from the Georges Bank, Gulf of Maine, and middle Atlantic Shelf areas. The data were submitted by J.E. O'Reilly at the Northeast Fisheries Center, Sandy Hook Laboratory, and were gathered from multiple research vessels between September 1978 and December 1982.

Use Cases

• Model historical phytoplankton biomass based on chlorophyll measurements.
• Analyze spatial patterns of marine productivity in the Georges Bank and Gulf of Maine areas.
• Study long-term changes in water quality based on phaeophytin data.

Strengths

• Data spans over four years, from 1978-09 20 to 1982-12-20.
• Spatial coverage includes multiple distinct marine areas: Georges Bank, Gulf of Maine, and the middle Atlantic Shelf.
• Data was collected from at least seven different research vessels, suggesting multiple sampling efforts.

Limitations

• Last updated 1982-12-20 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
