The region influenced by the Polar Front in Southern Ocean is characterized relatively high productivity, which mirrored strong depletions of 234 Th surface water, a good tracer export production, and accumulation rates on underlying seabed. Farther south, Weddell Sea generally considered low productivity with very fluxes. This finding based satellite observations, sediment rates, trap deployments, phytoplankton distribution. If this would be true, should close to equilibrium its parent....
A set of 114 samples from the sediment surface Atlantic, eastern Pacific and western Indian sectors Southern Ocean has been analyzed for 230 Th biogenic silica. Maps opal content, Th‐normalized mass flux, flux into have derived. Significant differences in sedimentation patterns between regions can be detected. The mean bulk vertical fluxes integrated open are found a narrow range 2.9 g m −2 yr −1 (Eastern Weddell Gyre) to 15.8 (Indian sector), setting upper lower limits vertically received...
The Southern Ocean (SO) plays a key role in modulating atmospheric CO 2 via physical and biological processes. However, over much of the SO, activity is iron‐limited. New situ data from Antarctic zone south Africa region centered at ∼20°E–25°E reveal previously overlooked high primary production, comparable size to northwest African upwelling region. Here, sea ice together with enclosed icebergs channeled by prevailing winds eastern boundary Weddell Gyre, where sharp transition warmer waters...
Analytical and 2D finite-element solutions of the heat transfer equation are used to model temperature evolution in upper 15 m marine sediment deposits. These calculations comprise realistic, in-situ measured, thermal properties as well natural (geothermal sea bottom temperature) man-made (e.g. high voltage, subsea power cables) sources. A main objective this article is focus on influence heterogeneity sediments North Baltic Seas. In combination with seasonal variations water temperatures,...
Abstract Heat flow measurements are a standard technique in Geophysics both onshore and offshore. Recently, such became increasingly important shallow waters. The increasing amount of offshore power installations makes it necessary to have good knowledge about the subsurface heat thermal properties sediments optimize construction powerlines. While well studied for deep ocean sediments, only few published data exist nearshore sediments. In this study, we investigate sediment temperatures...
