Abstract Global warming may modify submesoscale activity in the ocean through changes mixed layer depth (MLD) and lateral buoyancy gradients. As a case study we consider region NE Atlantic under present future climate conditions, using time‐slice method global nested regional models. The high resolution model reproduces strong seasonal cycle observed present‐day conditions. Focusing on well‐resolved winter months, future, with reduction MLD, there is substantial activity, an associated...

Abstract. While there is agreement that global warming over the 21st century likely to influence biological pump, Earth system models (ESMs) display significant divergence in their projections of future new production. This paper quantifies and interprets sensitivity projected changes production an idealized ocean biogeochemistry model. The model includes two tracers explicitly represent nutrient transport, light- nutrient-limited uptake by ecosystem (new production), export via sinking...

Abstract Global climate models provide useful tools to forecast large‐scale anthropogenic trends and the impacts on ocean physics marine biology chemistry. Due coarse spatial resolution, they typically lack ability represent important regional processes while underestimating mesoscale variability vertical mixing. This means limited value when it comes projections. We developed a submesoscale‐permitting physical/biogeochemical model dynamically downscale output of CMIP6 Earth System Model for...
Abstract The Hawaiian Island chain lies on the southern limb of oligotrophic North Pacific Subtropical Gyre, an area characterized by low productivity. In this region, productivity is controlled several factors, including island mass effect and mesoscale eddies generated wind stress curl in lee islands. This study identifies high‐chlorophyll events that occur periodically off northern coasts Main Islands. These are present satellite record can be reproduced using a regional dynamical model....
