Lay Abstract The study of transport by ocean currents has important applications for fisheries, conservation biology, pollution control, and military rescue missions, among others. Though the number observations world increased substantially in last decade, drifting induced at different depths is still not yet fully mapped or well understood. In this article we use an circulation model to oceanic within Canary Basin, located northeast Atlantic Ocean. To assess accuracy calculations,...
Abstract. This paper describes the implementation of a coupling between three-dimensional ocean general circulation model (NEMO) and wave (WW3) to represent interactions upper-oceanic flow dynamics with surface waves. The focus is on impact such upper-ocean properties (temperature currents) mixed layer depth (MLD) at global eddying scales. A generic interface has been developed, NEMO governing equations boundary conditions have adapted include wave-induced terms following approach McWilliams...
Abstract The oceanic circulation entering the tropical southwest Pacific (SWP) is dominated by broad westward flow of South Equatorial Current (SEC), which forced trade winds. It has been argued that numerous islands SWP are able to restructure SEC into a series deep and narrow zonal jets, control important pathways connecting equatorial extraequatorial signals. primary objective this paper improve understanding structure dynamics giving special attention topographic effects. This study...
Abstract Island wakes are areas of a strong eddy activity influencing the availability and transport organic matter in ocean which, turn impact biological productivity. Despite this, formation lee North Atlantic tropical islands is scarcely documented, except for Canary Islands. Moreover, occurrence anticyclones leeward Madeira has seldom been detected. During summer 2011, multiplatform approach, combining satellite data with situ measurements, was used to study an anticyclonic generated...
Abstract The Congo River has the second largest rate of flow in world and is mainly responsible for broad tongue low-salinity water that observed Gulf Guinea. Despite their importance, near-equatorial river plumes have not been studied as thoroughly midlatitude dynamics remain unclear. Using both theory idealized numerical experiments reproduce major characteristics region, authors investigated plume examine its sensitivity to different forcing mechanisms. It found are more likely be surface...
The trajectories of several Argo floats are studied to investigate the mid‐depth circulation in southwest Pacific that coincides with spreading Antarctic Intermediate Waters (AAIW). Before entering Coral Sea, converge and join North Caledonian Jet (NCJ) south 15°S. These observations suggest waters transported by this jet do not have a unique source. Hydrologic parameters oxygen concentration confirm characteristics AAIW NCJ result from convergence mixing northern limb subtropical gyre...
Abstract. A high-resolution ocean circulation modelling system forced with a numerical wind product was used to study the mesoscale and sub-mesoscale eddy population of North-Western Mediterranean Sea, contrasting eddy-activity between Tyrrhenian Ligurian sub-basins. Numerical solutions reproduced some known regional dynamics, namely occurrence oceanic implications Mistral events, convective cell leeward Gulf Lion, as well Balearic frontal system. Calculated transport across Corsica Channel...
We study numerically the role of mesoscale structures in Ligurian Sea (NW Mediterranean Sea) as a possible factor affecting spatial distribution chlorophyll spring bloom. use Regional Ocean Modeling System (ROMS) configured for NW (ROMS_NWMed) and satellite derived Altimetric, Surface Temperature Chlorophyll concentration data, years 2009 2010. Comparison model output with situ data shows agreement between numerical results observations. There is significant interannual variability basin...
An ocean circulation forecasting model for the Madeira Archipelago is operational since May 2010. Developing a system small island oceanic region, deprived from in-situ observations, challenging task there are limited ways to validate predictions. Furthermore, resolution concurrent with insufficient computational power, locally available, other limiting factors consider. Regional models combined possibility downscale solutions onto higher island-scale way overcome some of such limitations....
Abstract The oceanic circulation south of Africa is characterised by a complex dynamics with strong variability due to the presence Agulhas current and numerous eddies. This area interest also location several natural gas fields under seafloor which are targeted for drilling exploitation. powerful ocean currents induces significant issues ship operations at surface as well deep sea operations. Therefore, knowledge state ability forecast them in realistic manners could greatly enforce safety...
Coastal ecosystems are under climate and anthropogenic pressures. Extreme events as Marine Heatwaves (MHW) directly impact environmental conditions necessary to sustain biodiversity in coastal oceans. Recent results showed increasing occurrence intensity of MHW the Bay Biscay English Channel based on surface temperature observations. Combining satellite situ observations with recent high resolution numerical simulations, whole water column is investigated evaluate potential impacts pelagic...
