Eddy-induced enhancement of primary production in model of the North Atlantic Ocean
Article Abstract:
The export of photosynthetically fixed organic matter to the deep ocean must be balanced by the upward flow of nutrients to the euphotic zone. The eddy-induced nutrient supply has been investigated using a combination of two methods. Remotely sensed sea-surface height data from the TOPEX/Poseidon and ERS-1 satellite missions were incorporated into a numerical eddy-resolving coupled ecosystem/circulation model of the North Atlantic Ocean. Results suggest that mesocale eddy activity represents around one third of total nitrate flux into the euphotic zone.

The three-dimensional structure of an upper ocean vortex in the tropical Pacific Ocean
Article Abstract:
The flow of easterly trade winds, coupled with the Earth's rotation, drives surface currents away from the equator and causes an upwell in the water. The front created by upwell creates visible cusp-shaped disturbances called 'lines in the sea.' Measurements of one such occurrence reveals that the cusp-shaped disturbances are caused by instability of the mean zonal shear. Moreover, it was shown that these disturbances play a key role in the meridional transport of heat, salt and momentum.

Oxidation of the Ediacaran ocean
Article Abstract:
The high-resolution carbon isotope and sulphur isotope records from the Huqf Supergroup, Sultanate of Oman, that cover most of the Ediacaran period (approximately 635 to approximately 548 Myr ago) are presented. The data has presented insights into the oxygenation of the Ediacaran ocean and the stepwise restructuring of the carbon and sulphur cycles that occurred during this significant period of Earth's history.
