Stock dynamic of the Iberian sardine (Sardina pilchardus, W.) and its implication on the fishery off Galicia (NW Spain)

open access: yesScientia Marina, 2003
The recent failure of sardine catches off Galicia (NW Spain), an area where landings reached up to 100 thousand tonnes only a few years ago, may be explained by two possible hypotheses. The ";depletion"; hypothesis states that diminishing sardine catches

New Insights on Dissolved Organic Matter Cycling in the Cape Verde Frontal Zone From Its Optically Active Fraction

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 7, July 2025.
Abstract Absorption and fluorescence spectroscopy have been used to gain new insights on the dynamics of Dissolved Organic Matter (DOM) in the Cape Verde Frontal Zone (CVFZ), a highly dynamic area comprising the thermohaline Cape Verde Front (CVF) and the Cape Blanc Giant Filament (CBGF), which exports organic matter produced over the shelf to the ...

Seasonal Changes of Size Spectra of the Benguela Offshore Mesopelagic Ecosystem Compartment in Relation to Primary Production

open access: yesMarine Ecology, Volume 46, Issue 4, July/August 2025.
ABSTRACT Seasonal differences in marine size spectra of micronekton at the shelf‐ocean interface of the northern (NBUS) and southern Benguela upwelling system (SBUS) in Feb–Mar 2019 and Sep–Oct 2021 were analysed for mesopelagic fishes and total micronekton, the latter also including invertebrates.

Dissolved Organic Carbon in Coastal Waters: Global Patterns, Stocks and Environmental Physical Controls

open access: yesGlobal Biogeochemical Cycles, Volume 39, Issue 5, May 2025.
Abstract Dissolved organic carbon (DOC) in coastal waters is integral to biogeochemical cycling, but global and regional drivers of DOC are still uncertain. In this study we explored spatial and temporal differences in DOC concentrations and stocks across the global coastal ocean, and how these relate to temperature and salinity.

Dynamics of Near‐Bottom Currents in Cold‐Water Coral and Sponge Areas at Valdivia Bank and Ewing Seamount, Southeast Atlantic

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 1, January 2025.
Abstract This study investigates near‐bottom currents and physical processes from simulations with the hydrodynamic model ROMS‐AGRIF at two seamounts of the northeast Walvis Ridge to obtain valuable insights about drivers of observed occurrences of benthic suspension feeders (cnidarians and sponges) in this data‐poor area.

Research Trends and State of Knowledge of Decapod Crustaceans in Spain: A Bibliometric Analysis

open access: yesEcologies
The order Decapoda, comprising over 17,000 extant marine species, has maintained a significant association with human societies since ancient times. This prolonged interaction initially centered on their role as a food source, subsequently expanding to ...

Size-fractionated phytoplankton biomass and production in the tropical Atlantic

open access: yesScientia Marina, 2011
Two meridional transects were conducted in the tropical and subtropical Atlantic to describe (i) the spatial variability of total and size-fractionated (picophytoplankton and phytoplankton > 2 μm) chlorophyll a (chl a) concentration and primary ...
