High-latitude controls of thermocline nutrients and low altitude biological productivity

Article Abstract:

By tracing the combined distribution of silicic acid and nitrates in North Pacific, North Atlantic, Southern Ocean and in Subantarctic mode water (SAMW), the source of nutrients circulation for the thermocline are studied. The analysis has important implications for understanding large-scale controls on the nature and magnitude of low-latitude biological productivity and its sensitivity to climate change

The Southern Ocean biogeochemical divide

Article Abstract:

Study is presented to demonstrate that the atmospheric CO2 and global biological export production are controlled by different regions of Southern Ocean. The existence of this biogeochemical divide separating the Antarctic from the Subantarctic suggests that it may be possible for climate change or human intervention to modify one of these without greatly altering the other.

The Southern supplier

Article Abstract:

The North Atlantic Deep Water (NADW) and Subantarctic Mode Water (SAMW) within Southern Ocean and Northern Pacific links the global ocean and the atmosphere, driving the oceanic control of climate. Distribution of nutrients and exchange of heat repository and carbon-dioxide at ocean-atmosphere interface act as important factors.
