Abstract Hurricane Dorian (28-August to 6-September 2019) was one of the most powerful hurricanes ever recorded in the Atlantic Ocean; it had disastrous impact on the Bahamas, before moving along the southeastern coast of the U.S. The unusual track of Dorian followed the track of hurricane Matthew (2016)- both hurricanes moved along the Gulf Stream (GS) without making a significant landfall and both seemed to weaken the flow of the GS by almost 50%. In the case of Dorian, the transport of the Fl...
Abstract In autumn 2017, the influence of strong storms and mesoscale physical processes on phytoplankton has been studied in the Black Sea. Data on the taxonomic composition and biomass of phytoplankton, the concentration of chlorophyll-a (Chl), particulate organic carbon, primary production, chemical and physical properties of the environment were obtained using field observations, satellite scanners and two Bio-Argo floats. Different species predominated in cold-water and warm-water areas. In...
Abstract The interannual variability and the mechanisms controlling the dissolved oxygen concentration in the Mediterranean Sea were investigated through generating gridded fields of dissolved oxygen, salinity and temperature. The Data-Interpolating Variational Analysis (DIVA) software was used to produce a gridded dataset for the time period 1960–2011. High oxygen concentrations for the upper and bottom layers, separated by an oxygen minimum zone at intermediate layers, are a typical structure ...

Abstract Coastal upwelling regions represent less than 2% of the marine biosphere's volume. Nonetheless, local biogeochemical processes have a considerable impact on the structure and functioning of the global oceans. In this study we characterize the evolution of biogeochemical properties during the upwelling seasons of 2009 and 2010 in the coastal ecosystem off central Oregon (west coast of USA). Both years displayed similar cumulative upwelling favorable winds and total input of preformed nut...

Abstract Frequently-forming long-life mesoscale eddies are observed in the Algerian Basin that influence the circulation of the wider Western Mediterranean Sea. Most of these structures store and transport water masses including associated physical and biological properties throughout the entire basin. In order to study the evolution of a long-life anticyclonic eddy, we use a multiplatform approach based on remote sensing data analysis and in situ measurements. We present a case study of an anti...

Abstract A typhoon-induced storm surge simulation system was developed for the Zhejiang coast consisting of an assimilation wind-pressure model and the ADCIRC+SWAN model. The simulated peak and phase of the storm surge were found to match the observed data very well. We discussed the sensitivity of the modeled storm surge to changes in the computational domain, and compared the simulation results from the assimilation wind-pressure model and the symmetric Holland model. The sensitivity of 23 new...

Abstract Coastal ocean productivity is often dependent on riverine sources of nutrients, yet it can be difficult to determine how far the influence of the river extends. The northern Gulf of Mexico (GOM) receives freshwater and nutrients discharged mainly from the Mississippi and Atchafalaya Rivers. We used nutrient/salinity relationships to (i) differentiate the nutrient inputs of the two rivers and (ii) determine the potential extent of the zones where productivity is affected by each. We iden...

Abstract The Australian tropical storm surge forecasting system is described, including the development of a tropical cyclone atmospheric forcing model and the configuration of the ocean hydrodynamic model. The atmospheric model is developed as an asymmetric modified Rankine vortex and the resulting time dependent stress and pressure fields are applied to a shallow water hydrodynamic model. The system was benchmarked against seven contemporary tropical cyclones occurring within the northern Aust...

Abstract An integrated habitat suitability index (HSI) model was developed for a pelagic commercial squid Ommastrephes bartramii in the Northwest Pacific Ocean based on three crucial environmental variables: sea surface temperature (SST), chlorophyll-a concentration (Chla) and sea surface height (SSH). The model was established by data from 2006 to 2014 and validated by data in 2015 on the basis of fishing effort and CPUE (catch-per-unit-effort). Results suggested that the HSI model had good cap...
