Bioavailable iron in the Southern Ocean: the significance of the iceberg conveyor belt
Productivity in the Southern Oceans is iron-limited, and the supply of iron dissolved from aeolian dust is believed to be the main source from outside the marine reservoir. Glacial sediment sources of iron have rarely been considered, as the iron has been assumed to be inert and non-bioavailable. This study demonstrates the presence of potentially bioavailable Fe as ferrihydrite and goethite in...
متن کاملTracing the conveyor belt in the Hamburg large-scale geostrophic ocean general circulation model
The flow which constitutes the conveyor belt in the Hamburg large-scale geostrophic ocean general circulation model has been investigated with the help of a particle tracking method. In the region of North Atlantic Deep Water formation a thousand trajectories were calculated backward in time to the point where they upwell from the deep ocean. Both the three-dimensional velocity field and convec...
متن کاملTasman leakage: A new route in the global ocean conveyor belt
[1] The existence of a new route that draws relatively cold waters from the Pacific Ocean to the North Atlantic via the Tasman outflow is presented. The new route materialises with comparable magnitude and characteristics in three independent numerical realisations of the global ocean circulation. Its realism is supported by hydrographic data interpolated via an inverse model. The ‘‘Tasman leak...
متن کاملOcean Currents Modeling along the Iranian Coastline of the Oman Sea and the Northern Indian Ocean
The Makran Coast (Iranian Coastline of the Oman Sea on the Northern Indian Ocean) plays an important role in country’s future navigation and trade due to its accessibility. In 2014, the Iranian Makran coastline was selected by the PMO to be studied as the Phase 6 in the series of Monitoring and Modelling Studies of Iranian Coasts with all disciplines being in investigated including currents. Al...
متن کاملReexamining the Cold Conveyor Belt
Despite the popularity of the conveyor-belt model for portraying the airflow through midlatitude cyclones, questions arise as to the path of the cold conveyor belt, the lower-tropospheric airflow poleward of and underneath the warm front. Some studies, beginning with Carlson’s analysis of the eastern U.S. cyclone of 5 December 1977, depict the cold conveyor belt moving westward, reaching the no...
