TLDR
In this paper, the authors analyzed connections between larval supply to the Canary Islands (CI) and sardine and anchovy populations that spawn over the continental shelf for both species, i.e., at the shelf and near the island of Gran Canaria (GC).About:

TL;DR: In this article, a series of interdisciplinary field studies was conducted on the Canary Island archipelago to investigate the role of cyclonic eddies in the transport and exchange of biogenic material including fish larvae.

Seasonal variability of the Canary Current: A numerical study
Evan Mason,Evan Mason,François Colas,Jeroen Molemaker,Alexander F. Shchepetkin,Charles Troupin,James C. McWilliams,Pablo Sangrà +7 more
TL;DR: In this paper, a high-resolution numerical model study of the Canary Basin in the northeast subtropical Atlantic Ocean is presented, which reveals mesoscale variability associated with the Azores and Canary Current systems, the northwest African coastal upwelling, and the Canary Island archipelago.
Journal ArticleDOI
Comparative study of potential transfer of natural and anthropogenic cadmium to plankton communities in the North-West African upwelling.
TL;DR: Based upon an estimate of Cd sources, the modeling study shows, unexpectedly, that the anthropogenic signal of potential Cd-bioaccumulation in the Moroccan upwelling is of the same order of magnitude as the natural signal mainly present in the Senegalo-Mauritanian up welling region.
Journal ArticleDOI
Lagrangian transport pathways in the northeast Atlantic and their environmental impact
TL;DR: In this paper, the authors focused on mapping the general transport pathways of the northeast Atlantic Ocean by using the Regional Oceanic Modeling System to calculate ocean current velocity components (u, v, w), and Ariane (an off-line Fortran code dedicated to the computation of three-dimensional streamlines from velocity fields) to calculate the transport of particles around the numerical model domain.
Journal ArticleDOI
On the long-range offshore transport of organic carbon from the Canary Upwelling System to the open North Atlantic
TL;DR: In this article, the authors employ a new Atlantic telescopic grid with a strong refinement towards the northwestern African shelf to combine an eddy-resolving resolution in the Canary Upwelling System (CanUS) with a full Atlantic basin perspective.

The regional oceanic modeling system (ROMS): a split-explicit, free-surface, topography-following-coordinate oceanic model
TL;DR: In this paper, a split-explicit hydrodynamic kernel for a realistic oceanic model is proposed, which addresses multiple numerical issues associated with mode splitting, and is compatible with a variety of centered and upstream-biased high-order advection algorithms, and helps to mitigate computational cost of expensive physical parameterization of mixing processes and submodels.

TL;DR: The combination of moderate-order spatial approximations, enhanced conservation properties, and quasi-monotone advection produces both more robust and accurate, and less diffusive, solutions than those produced in earlier terrain-following ocean models.

Small pelagics in upwelling systems: patterns of interaction and structural changes in "wasp-waist" ecosystems

TL;DR: It is doubtful that pelagic fisheries will continue to increase without major disruptions to ecosystems, and predation on zooplankton by the jack mackerel in the South Pacific provides an example of the alteration of matter fluxes in trophic webs caused by fishery removals.

Optimal Environmental Window and Pelagic Fish Recruitment Success in Upwelling Areas
Philippe Cury,Claude Roy +1 more
TL;DR: It is hypothesize that relations between annual recruitments and upwelling intensity are dome shaped in Ekman-type upwellings and linear for non EkMan-typeUpwelling, where upwelled intensity is not correlated with wind speed.
