The Makran Coast (Iranian Coastline of the Oman Sea on the Northern Indian Ocean) plays an important role in country’s future navigation and trade due to its accessibility. In 2014, the Iranian Makran coastline was selected by the PMO to be studied as the Phase 6 in the series of Monitoring and Modelling Studies of Iranian Coasts with all disciplines being in investigated including currents. Al...

Ocean currents play a key role in Earth’s climate, they are of major importance for navigation and human activities at sea, and impact almost all processes that take place in the ocean. Nevertheless, their observation and forecasting are still difficult. First, direct measurements of ocean currents are difficult to obtain synoptically at global scale. Consequently, it has been necessary to use ...

The Indus fan is the most pronounced and extensive physiographic and sedimentary feature of the Arabian Sea as well as it is the second largest submarine fan in the world. It has developed off the passive continental margin of Pakistan and India, covering an area of about 1.1 x10 km which makes it one of the largest sediment bodies in the ocean basins, totalling ~5 x 10 km in volume. The presen...

Patterns of seed dispersal in the wild sea beet (Beta vulgaris ssp. maritima) are predicted to be influenced by marine currents because populations are widely distributed along the European Atlantic coast. We investigated the potential influence of marine currents on the pattern of spatial genetic structuring in natural populations of sea beet. Populations were located along the French coasts o...

Two remote sensing methods, satellite altimetry and 4D-Var assimilation of satellite imagery, are used to compute surface velocity fields in the Black Sea region. Surface currents derived from the two methods are compared for several cases with intense mesoscale and large-scale dynamics during low wind conditions. Comparison shows that the obtained results coincide well quantitatively and quali...

Ocean currents play a key role in Earth’s climate – they impact almost any process taking place in the ocean and are of major importance for navigation and human activities at sea. Nevertheless, their observation and forecasting are still difficult. First, no observing system is able to provide direct measurements of global ocean currents on synoptic scales. Consequently, it has been necessary ...

Drifter and satellite data are assimilated into a circulation model that hindcasts near-surface currents in the Northeastern Gulf of Mexico. Experiments without assimilation, and using assimilation of drifter, satellite sea-surface height (SSH) and sea-surface temperature (SST) data, in various combinations, were conducted. Currents derived from these experiments were used to compute drifter tr...

In recent studies [1], we have already shown that it is possible to derive mesoscale sea surface current fields by tracking signatures of marine surface films in multisensor satellite data. Although the derived sea surface current fields corresponded well with those provided by numerical models, the former mainly showed largescale current properties. This is insofar remarkable, as the traced si...
