Abstract. It is hypothesized that more accurate prediction and warning of natural hazards, such as the impacts severe weather mediated through various components environment, require a integrated Earth System approach to forecasting. This hypothesis can be explored using regional coupled systems, in which known interactions feedbacks between different physical biogeochemical environment across sky, sea land simulated. Such systems are becoming increasingly common research tools. paper...

Abstract. The Humboldt Large Marine Ecosystem (HLME) and Patagonian (PLME) are the two largest marine ecosystems in Southern Hemisphere respectively located along Pacific Atlantic coasts of southern South America. This work investigates exchange between these LMEs its seasonal interannual variability by employing numerical model results offline particle-tracking algorithms. Our analysis suggests a general poleward transport on region HLME, well-defined flux from to Atlantic, equatorward...

Abstract The North West European Shelf break acts as a barrier to the transport and exchange between open ocean shelf seas. strong spatial variability of these processes is hard fully explore using observations, simulations generally are too coarse simulate fine‐scale over whole region. In this context, under FASTNEt program, new NEMO configuration Atlantic Margin at 1/60° (∼1.8 km) has been developed, with objective better understand quantify seasonal interannual processes. capability...

River freshwater contribution in the European Atlantic margin and its influence on sea salinity field are analyzed. The impacts of using a new river discharge database as part forcing regional ocean model assessed. Ocean scenarios, based CMEMS (Copernicus Marine Environment Monitoring Service) operational IBI-MFC (Iberia Biscay Ireland Forecasting Centre) set-up, run to test different (observed, modeled climatological) coastal configurations throughout 2018. modelled fields validated,...

The manuscript analyses Eulerian transports and Lagrangian pathways between ecosystem regions on either side of southern South America.It is not my region expertise, but from the past research described in manuscript, it seems that previously there has been only limited observations modelling work focused this region.Therefore appears results will fill a gap regional oceanographic knowledge are worth publishing, after addressing below comments.

This study uses ROMS / NEMO ocean circulation models and a Lagrangian particle tracking routine to transport of water around southern South America (1) between the deep coastal regions (2) Pacific Atlantic coasts.The represents considerable amount effort on part authors they have done good job thoroughly exploring models.I think paper could be benefited by few additional considerations.
