Temperature at sea floor during the month of July, averaged over NAFO areas 4X, 4W and 4V.
Temperature at sea surface averaged over NAFO regions 4V, 4X and 4W as well as regional areas (Bay of Fundy + Gulf of Maine)
North Atlantic Oscillation Index (NAO), calculated using sea level pressure difference between subtropical high and subpolar low
Atlantic Multidecadal Oscillation Index (AMO), based on anomalies of sea surface temperatures in North Atlantic basin.
A measure of the volume of the cold intermediate layer throughout the Gulf of St. Lawrence
Average ice volume for January - March in the Gulf of St. Lawrence, can be reasonably used as a proxy to represent sea ice volume on the Scotian Shelf.
An index of stratification, measured as the density difference between 0 and 50 metres
Averaged water temperatures at sea floor, over NAFO areas 4X, 4V and 4W
Minimum temperature in the cold intermediate layer within the Gulf of St. Lawrence
Discrete salinity measurements over a range of depths
Discrete sea temperature measurements over a range of depths
Averages of sea surface temperatures infered from remote sensing (satellite) measurements
Derived metric calculating the warming of sea surface temperature averages over the Scotian Shelf
The final day of sea ice observed in the Gulf of St. Lawrence. Note that this metric can be used as a reasonable proxy for the Scotian Shelf
Average of sea ice area, seaward of Cabot Strait
Average surface chlorophyll as inferred from satellite (remote sensing) measurements
