Submesoscale Coherent Structures on the Continental Shelf

Drilling Productivity on the Norwegian Continental Shelf

Recently, we have seen falling oil prices combined with sticky costs at a high level in the petroleum industry. This cause cost cuts and project postponements, thus challenging reserve replacement of oil companies and security of supply for consumers. Costs are particularly high for drilling. High rig rates are obviously important. In new contracts for high-spec semi rigs on the Norwegian Conti...

Three-Dimensional Model for the Formation of Longshore Sand Structures on the Continental Shelf

i ii Abstract A model is proposed for the formation and evolution of three-dimensional sedimen-tary structures such as longshore sand ridges on the continental shelf in water deeper than that of the shoaling region. Owing to the striking similarity between the bar spacing and the length scales in which interactions among the most energetic modes of shallow water waves take place, we argue that ...

Observations of Cross-Shelf Flow Driven by Cross-Shelf Winds on the Inner Continental Shelf

Six-yr-long time series of winds, waves, and water velocity from a cabled coastal observatory in 12 m of water reveal the separate dependence of the cross-shelf velocity profile on cross-shelf and along-shelf winds, waves, and tides. During small waves, cross-shelf wind is the dominant mechanism driving the cross-shelf circulation after tides and tidal residual motions are removed. The along-sh...

On the freshening of the northwestern Weddell Sea continental shelf

We analyzed hydrographic data from the northwestern Weddell Sea continental shelf of the three austral winters 1989, 1997, and 2006 and two summers following the last winter cruise. During summer a thermal front exists at ∼64 S separating cold southern waters from warm northern waters that have similar characteristics as the deep waters of the central basin of the Bransfield Strait. In winter, ...
