Atmospheric Control of Deep Chlorophyll Maximum Development

open access: yesGeosciences, 2019
The evolution of the near-surface phytoplankton bloom towards a Deep Chlorophyll Maximum (DCM) in mid-latitudes and subpolar regions of the global ocean is a well-known biological feature.

Sentinels of Seabed (SoS) indicator: Assessing benthic habitats condition using typical and sensitive species

open access: yesEcological Indicators, 2022
Indicators are key tools used to assess the ecological status of the environment for ecosystem based management. Anthropogenic disturbances produce changes to habitat condition, which include modifications in species composition and their functions ...

3D Fine-scale Terrain Variables from Underwater Photogrammetry: A New Approach to Benthic Microhabitat Modeling in a Circalittoral Rocky Shelf

open access: yesRemote Sensing, 2020
The relationship between 3D terrain complexity and fine-scale localization and distribution of species is poorly understood. Here we present a very fine-scale 3D reconstruction model of three zones of circalittoral rocky shelf in the Bay of Biscay ...

Demersal and epibenthic assemblages of trawlable grounds in the northern Alboran Sea (western Mediterranean)

open access: yesScientia Marina, 2007
The composition and abundance of megabenthic fauna caught by the commercial trawl fleet in the Alboran Sea were studied. A total of 28 hauls were carried out at depths ranging from 50 to 640 m.

Models describing mackerel (Scomber scombrus) early life growth in the North and Northwest of the Iberian Peninsula in 2000

open access: yesScientia Marina, 2004
Mackerel (Scomber scombrus) in early life stages were captured in 2000 in the north and northwest of the Iberian Peninsula (ICES Divisions VIIIc and IXa North). Daily rings on their otolith sagittae were identified.

Community Composition and Habitat Characterization of a Rock Sponge Aggregation (Porifera, Corallistidae) in the Cantabrian Sea

open access: yesFrontiers in Marine Science, 2020
Deep-sea sponge-dominated communities are complex habitats considered hotspots of biodiversity and ecosystem functioning. They are classified as Vulnerable Marine Ecosystem and are listed as threatened or declining as a result of anthropogenic activities.

Timing of Increment Formation in Atlantic Bluefin Tuna (Thunnus thynnus) Otoliths

open access: yesFishes, 2022
Controversies remain regarding the periodicity, or seasonality, of otolith growth band formation, which directly influences a correct age determination of Atlantic bluefin tuna using this structure.

Influence of seasonal variability on the trophic structure of pelagic communities

open access: yesFrontiers in Marine Science, 2023
Seasonal variations in hydrodynamic conditions play a critical role in prey availability at the base of the food web and thus have implications for trophic interactions at higher trophic levels.
