Hudson Strait Oceanographic Data from Four Moorings, 2008-2009

Four moorings deployed in Hudson Strait, Canada, collected temperature, salinity, conductivity, and pressure data from August 2008 to September 2009. Mooring A on the south side had four instruments at depths of 25, 45, 100, and 160 meters, while three moorings (E, F, G) on the north side had two to four instruments at depths ranging from 25 to 320 meters. The data were collected by NOAA NCEI to measure freshwater exchange between the Arctic Ocean and the Labrador Sea.

Use Cases

• Calculate freshwater flux into Hudson Bay based on salinity and temperature measurements across the strait.
• Model ocean stratification and water mass properties based on vertical profiles from multiple depths.
• Analyze seasonal variability in oceanographic conditions from the year-long time series.
• Validate regional ocean circulation models using in-situ data from a key Arctic gateway.

Strengths

• Data collected from four distinct mooring locations providing spatial coverage across the strait.
• Instruments deployed at multiple depths (from 25m to 320m) enabling vertical profile analysis.
• Time series spans over one year (August 2008 to September 2009), capturing seasonal cycles.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
