Mud sedimentation on the continental shelf at an accretionary margin—Poverty Bay, New Zealand

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...

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...

Effects of Habitat Structure on Distribution and Abundance of Lizards at Pukerua Bay, Wellington, New Zealand

The distribution and abundance of lizards relative to habitat structure were studied at Pukerua Bay, Wellington between December 1982 and March 1988 in order to identify options for management of the habitat of the five species of lizards present. One species, Whitaker’s skink (Cyclodina whitakeri), is a threatened species with only one known mainland population. Pitfall traps were set for 23 6...

Nonlinear internal waves over New Jersey’s continental shelf

[1] Ship and mooring data collected off the coast of New Jersey are used to describe the nonlinear internal wave (NLIW) field and the background oceanographic conditions that formed the waveguide on the shelf. The subinertial, inertial, and tidal circulation are described in detail, and the background fluid state is characterized using the coefficients of the extendedKorteweg–deVries equation. ...
