Atlantic Water (AW) is a water mass traditionally defined as any water with salinity greater than 35.0 entering the Arctic domain from the Atlantic domain.

AW first entering the Iceland and Norwegian Seas typically has temperatures of six to eight degrees Celsius (C) and a salinity range of about 35.1 to 35.3, although the property ranges of other waters obviously connected with AW have prompted some to expand the definition to include all waters warmer than three degrees C and more saline than 34.9. Estimates of the total influx of AW range as high as nine Sverdrups.
