Seasonal composites from 1998 onward show chlorophyll concentrations in the Gulf of Maine. The raster images were processed by NOAA_NCEI to remove land and no-data values and calculate real-world values in micrograms per liter. The dataset was last updated in 2005.
Use Cases
- Analyze seasonal phytoplankton bloom patterns based on chlorophyll concentration composites.
- Study long-term changes in marine productivity based on reprocessed raster images.
- Model oceanographic conditions in the Gulf of Maine based on seasonal mean or median chlorophyll values.
- Validate satellite-derived ocean color data based on the reprocessing methods described.
Strengths
- Data is reprocessed to remove land and specific no-data values (0, 251, 252, 253).
- Real-world chlorophyll values are calculated in micrograms per liter.
- Seasonal composites are defined clearly (Fall, Winter, Spring, Summer).
Limitations
- Last updated 2005-01-01 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.
