The Arctic Ocean is a hub of globally significant, intersecting economic and environmental activity and interest. Climate change has disproportionately impacted the region, resulting in rising ocean temperatures and continued loss of summer sea ice. Natural resource exploration and extraction initiatives also have an increased presence and impact within the region.

All longitudes from 60°N to 90°N latitudes.
Temperature and salinity are available on a 1°x1° and a 1/4°x1/4° latitude/longitude grid.
Each climatology has an annual (all-data), seasonal, and monthly time period calculation. Seasons are Winter (Jan.-Mar.), Spring (Apr.-Jun.), Summer (Jul.-Sep.), and Fall (Oct.-Dec.).
Temperature and salinity are available on 87 standard levels with higher vertical resolution than the World Ocean Atlas 2009 (WOA09), but levels extend from the surface to 4000 m.
- Statistical means (before objective analysis)
- Standard deviation
- Standard error
- Data distribution
- Observed minus analyzed
- Difference of time period from annual climatological mean
- Unitless on the Practical Salinity Scale-1978 [PSS]
1° and 1/4° climatologies use ETOPO2 grid square mean
The method used to calculate the mean climatological fields is detailed in Temperature: Locarnini et al., 2010, Salinity: Antonov et al., 2010. Additional details on the 1/4° climatological calculation are found in Boyer et al., 2005. The table from this publication giving radius of influence for the analysis procedure can be filled out with values for the 1/4° procedure as follows:
|Pass||1° radius of influence||1/4° radius of influence|
|1||892 km||321 km|
|2||669 km||267 km|
|3||446 km||214 km|
