Subantarctic Mode Water
Subantarctic mode water (SAMW) is an important water mass in the earth's oceans. It is formed near the Subantarctic Front on the northern flank of the Antarctic Circumpolar Current. The surface density of Subantarctic Mode Water ranges between about 1026.0 and 1027.0 kg/m3 and the core of this water mass is often identified as a region of particularly low stratification.
Additional recommended knowledge
Another important facet of SAMW is that silicate (an important nutrient for diatoms) is relatively depleted relative to nitrate. This depletion can be tracked over much of the globe, suggesting that SAMW helps set the blend of nutrients delivered to low-latitude ocean ecosystems, and thus determines the balance of species within these ecosystems.
