La articulación de los litorales de Colombia como Zona Marítima Estratégica

open access: yesRevista Científica General José María Córdova
Este artículo analiza la importancia estratégica de la hidropolítica en la actualidad a partir de la competencia entre grandes potencias en las zonas marítimas estratégicas más significativas, con el fin de comprender la posición geográfica especial que

Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary

open access: yesEnvironmental Microbiology, Volume 28, Issue 8, August 2026.
Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...

Temporal variation of PCB concentrations in mussel tissue in two areas of Santander Bay (Spain)

open access: yesCiencias Marinas, 2006
An analysis was made of the temporal variation of polychlorinated biphenyls (PCBs) in wild mussel, Mytilus galloprovincialis, from two areas of Santander Bay (northern Spain) during 1991–2003, as well as of the posible influence of different external ...

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

The feeding behaviour of some demersal fish species in response to artificial discarding

open access: yesScientia Marina, 2002
In an attempt to detect changes in the diet and the feeding intensity of demersal fish caused by fishery discarding, two hauls were carried out 22 h apart at a depth of 90 m in an area of the Cantabrian Sea closed to trawling.

Evidence for Countergradient Growth Adaptation and Jordan's Rule in a Southern Hemisphere Fish, the Atherinopsid Odontesthes regia

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
We performed common garden experiments on offspring of the sea silverside Odontesthes regia to characterize thermal growth reaction norms of different populations along the Chilean coast. This showed that the species exhibits local adaptation in the form of countergradient growth adaptation because higher‐latitude southern populations grew faster at ...

Climatology and reconstruction of runoff time series in northwest Iberia: influence in the shelf buoyancy budget off Ría de Vigo

open access: yesScientia Marina, 2010
River runoff off northwest Iberia generates a low-density buoyant structure with a strong influence on shelf and coastal circulation. This study estimates the runoff to the shelf of the ten largest rivers in the region based on the furthest downstream ...

Spatial characterization of the fisheries in the Avilés Canyon System (Cantabrian Sea, Spain)

open access: yesCiencias Marinas, 2016
Marine protected areas are one of the main tools in ecosystem-based fishery management. This approach requires analyzing the role of fisheries in the ecosystem by, for example, identifying fishing tactics and analyzing the spatial distribution with ...

Using routine hydrographic sections for estimating the parameters needed for Optimal Statistical Interpolation. Application to the northern Alboran Sea

open access: yesScientia Marina, 2005
Optimal Statistical Interpolation is widely applied in the analysis of oceanographic data. This technique requires knowing some statistics of the analysed fields such as the covariance function and the noise to signal ratio.
