Role of mean circulation, tides, and waves in the transport of bottom sediment on the New Zealand continental shelf

摘要: Abstract Evaluation of velocity data on water movements over the New Zealand continental shelf has revealed that mean circulation by itself is too slow to induce transport bottom sediments. Tides generally have higher velocities, but are still not main transporting agent except in tide‐dominated Cook and Foveaux. Straits. Waves potential stir sediments inner middle (less than about 70 m deep) during annual storms, probably down 130 depth maximum 25‐y storm. For sediment take place, energies at least two major would complement one another. Optimum conditions for occur storm periods when wave‐suspended readily moved tides circulation.
