The effect of advection on the nutrient reservoir in the North Atlantic subtropical gyre
Article Abstract:
A study is conducted to show that the production and advection of North Atlantic Subtropical Mode Water introduces spatial and temporal variability in the subsurface nutrient reservoir beneath the North Atlantic subtropical gyre. It is found that cold winters that promote deep convective mixing and vigorous mode water formation may diminish downstream primary productivity by altering the subsurface delivery of nutrients.

Decline of the marine ecosystem caused by a reduction in the Atlantic overturning circulation
Article Abstract:
A disruption of the Atlantic meridional overturning circulation leads to a collapse of the North Atlantic plankton stocks to less than half of their initial biomass, owing to the rapid shoaling of winter mixed layers and their associated separation from the deep ocean nutrient reservoir. The studies suggest that global ocean productivity is sensitive to changes in the Atlantic meridional overturning circulation.

Something stirs in the deep
Article Abstract:
Scientists Walter Munk and Carl Wunsch have devised a mathematical solution to describe the warming of oceanic waters located in abyssal regions. Wunsch and Munk believes that the Moon and wind forces promote mechanical circulatory patterns in the ocean, causing tidal dissipation. Their theories, dubbed 'Abyssal recipes II', should be reinforced with modelling research.
