Oceanographic Conditions on Scotian Shelf and Gulf of Maine 2013

2013 oceanographic data from Fisheries and Oceans Canada details temperature, stratification, and plankton anomalies on the Scotian Shelf and eastern Gulf of Maine. The dataset includes figures and tables analyzing annual average temperature, surface nitrate inventories, spring bloom chlorophyll peaks, and zooplankton biomass. It provides an initial evaluation of relationships among physical variables, nitrate, and zooplankton from 1999 to 2013 at the Halifax-2 station.

Use Cases

• Analyze annual average temperature anomalies and stratification variability across the Scotian Shelf and Gulf of Maine.
• Correlate spring bloom chlorophyll peak magnitude with surface nitrate inventories and zooplankton biomass anomalies.
• Evaluate the abundance of Calanus finmarchicus and Pseudocalanus spp. copepods relative to temperature and stratification data.
• Model relationships between bloom duration, upwelling, and zooplankton biomass using the 1999-2013 Halifax-2 station time series.

Strengths

• Data originates from Fisheries and Oceans Canada, a government scientific authority.
• Includes a multi-year analysis from 1999 to 2013 for the Halifax-2 station, providing temporal context.
• Covers a specific geographic region: the Scotian Shelf and eastern Gulf of Maine.

Limitations

• Data is limited to the year 2013 for the primary analysis, with a single year of comprehensive conditions.
• The abstract suggests strong sub-annual and mesoscale variability, indicating data may be complex and require spatial-temporal expertise.
• Specific row counts, column structures, and file sizes are unknown from the provided metadata.
