A mesoscale eddy is detected and tracked in the western North Pacific region. Within life cycle of cyclonic eddies, intensities eddies make a difference. Satellite images indicate oceanic keeps westward-moving until it disappears. Oceanographic acoustic characteristics are studied. The energy distribution results from different intensity both modelled measured calculated. With sound propagation...

Simulation of dam breach scenarios can help in the preparation emergency action plans for real breaks or flash flooding events. The purpose this study was to identify flood-prone areas Al Wala Valley governorate Madaba Jordan through analysis Dam. Modelling breaches conducted under two scenarios: a Clear Day scenario and Probable Maximum Flood (PMF) scenario. former does not address various fai...

The deep ocean conditions and circulation during the Cretaceous have been characterized mainly by the sediments from the Tethys Sea and the proto-Atlantic Ocean, because sedimentological data from the Pacific basin from that period have been quite limited. Here we present new geochemical measurements from sediments that we collected from two sites in Hokkaido, Japan, that were presumably deposi...

Penguin foraging and breeding success depend on broad-scale environmental and local-scale hydrographic features of their habitat. We investigated the effect of local tidal currents on a population of Adélie penguins on Humble Is., Antarctica. We used satellite-tagged penguins, an autonomous underwater vehicle, and historical tidal records to model of penguin foraging locations over ten seasons....

Understanding and managing an ecosystem without knowledge of circulation patterns and hydrography would be like trying to diagnose a patient without taking their pulse and temperature. In order to improve our understanding and prediction of ecosystem dynamics, we must improve our knowledge of the processes and mechanisms that link changes in the physical environment to biological variability. T...

The Great Australian Bight south of Australia is an important link for the flow of surface, intermediate and deep water between the Indian and Pacific Ocean. Carbon-14 is a tracer of this flow and for the first time, water samples for subsequent carbon-14 analysis were collected at several locations within the Bight. We report and discuss the observed carbon-14 distribution in relation to the g...

A thermodynamically interactive ice shelf cavity parameterization is coupled to the Regional Ocean Model System (ROMS) and is applied to the Southern Ocean domain with enhanced resolution in the Weddell Sea. This implementation is tested in order to assess its degree of improvement to the hydrography (and circulation) of the Weddell Sea. Results show that the inclusion of ice shelf cavities in ...
