Global chlorophyll distribution induced by mesoscale eddies
, 2021While mesoscale eddies can trap and transport chlorophyll (CHL) within the water columns, satellite measurements can only observe CHL at the sea surface.

The influence of mesoscale dynamics on variability of phytoplankton biomass in terms of chlorophyll-a (chl-a) concentration was studied in the coastal waters of the South Eastern Arabian Sea (SEAS) using long-term satellite data. Satellite-derived chl-a,

Ocean Modelling, 2005
Abstract Mesoscale eddies are not resolved in coarse resolution ocean models and must be modeled. They affect both mean momentum and scalars. At present, no generally accepted model exists for the former; in the latter case, mesoscales are modeled with a bolus velocity u ∗ to represent a sink of mean potential energy.

Westward motion of mesoscale eddies
Deep Sea Research Part B. Oceanographic Literature Review, 1990Abstract Since the pioneering work of Nof, the determination of the westward drift of mesoscale eddies under the planetary (beta) effect has been a recurrent theme in mesoscale oceanography, and several different formulae have been proposed in the literature.

Oceanic mass transport by mesoscale eddies
Science, 2014Spinning up ocean circulation discretely Ocean eddies with diameters of tens to hundreds of kilometers are an important component of water transport on a global scale. Averaged over periods of many years, ocean circulation is regular and coherent enough to have been described as a conveyor belt. However, over shorter time scales,

Mesoscale eddies play a key role in ocean biogeochemistry, yet their effects on dinitrogen ( N 2 ) fixation are not well understood. Using quantitative polymerase chain reaction (qPCR) and dinitrogen-15 (15N2) tracer methods, we examined the abundance of

Towards a mesoscale eddy closure
Ocean Modelling, 2008Zusammenfassung A turbulence closure for the effect of mesoscale eddies in non-eddy-resolving ocean models is proposed. The closure consists of a prognostic equation for the eddy kinetic energy (EKE) that is integrated as an additional model equation, and a diagnostic relation for an eddy length scale (L), which is given by the minimum of Rhines scale

Characteristics and vertical structure of oceanic mesoscale eddies in the Bay of Bengal
, 2020The signatures of mesoscale eddies induced surface and subsurface changes have not been comprehensively quantified for the Bay of Bengal (BoB) region. This study quantifies the statistical properties and three-dimensional (3D) eddy structures in the BoB.
