This database contains biological-fishery information on the pelagic fish Bigeye scad (Selar crumenophthalmus), captured in the Colombian Caribbean with a handline and using different hooks sizes (No. 12, 13 and 14, type J). The morphometric variables measured were total length, standard length and mouth length. The information recorded during 2019 is useful for estimating the selectivity parameters of the Bigeye scad captured with artisanal hand [...]

Satellite images from Antarctica reveal important changes in the coastal icescape (fast-ice, icebergs and ice shelves) but these yearly changes and their impacts on the coastal circulation and ice shelf basal melt rates are not represented in the Earth System Models used to project future sea level rise. The impacts of these yearly icescape changes are thus investigated using a high-resolution regional ocean-ice shelves-sea ice coupled model of t [...]

The AMORGOS-23 cruise (https://doi.org/10.17600/18003211) was conducted onboard R/V Europe from April 26th 2023 to May 9th 2023. Using HROV Ariane equipped with 4K cameras, we surveyed the main active faults between Amorgos and Anafi islands in order to identify and quantify recent deformation of the seafloor linked to the 1956 Amorgos earthquake. During dive 244-1, we surveyed the steepest scarp of the Amorgos fault, along its central segment. W [...]

Recent reconversion from pelagic to demersal fishing activity and intense fishing effort has led to large scale declines in Mediterranean European hake (Merlucius merluccius) populations. However, to date, a lack of understanding in spatially explicit fisheries dynamics raises uncertainty in how management under the 2020 Northwest Mediterranean management plan will impact hake, and what this will mean for fisheries. Here we introduce a spatialize [...]

Near-bottom multibeam bathymetry and back-scatter data acquired along the Amorgos and Santorini-Amorgos faults, in the Aegean sea. High-resolution bathymetry data (1 m/pixel) were acquired by the autonomous underwater vehicle (AUV) IdefX, deployed during the AMORGOS-22 cruise (https://doi.org/10.17600/18001479) with the MBES EM2040. The dataset consists of six DEMs as well as fourteen back-scatter mosaics (i.e. two versions for each dives, raw an [...]

Three oceanographic cruises were organized in the seas around Sardinia (western Mediterranean) between September 2019 and September 2021 (see the table) by the Italian National Research Council (CNR) and the acquisition of 241 hydrological vertical profiles by a SBE 911plus V 5.1g. Data of conductivity (SBE-4 sensor, resolution of 3 x 10-4 S/m), temperature (SBE-3/F thermometer, resolution of 0.00015 °C/bit at -1 °C or 0.00018 °C/bit at 31 °C), d [...]

The RESILIENCE experiment took place in April and May 2022 on the R/V Marion Dufresne in the Southwestern Indian Ocean, South of the Mozambique Chanel and offshore of Durban (South Africa). The main scientific objective was to study the interaction at fine scale (about 10km) between physics and biology. To do so CTD stations were performed accompanied by MVP profiles, measuring temperature, conductivity (hence salinity) and fluorescence. The MVP [...]

Imagery has become one of the main data sources for investigating seascape spatial patterns. This is particularly true in deep-sea environments, which are only accessible with underwater vehicles. On the one hand, using collaborative web-based tools and machine learning algorithms, biological and geological features can now be massively annotated on 2D images with the support of experts. On the other hand, geomorphometrics such as slope or rugosi [...]

The PHYTOBS-MARCOBOLO dataset comprises long-term time series on marine microphytoplankton, from 2003 to 2021, along the entire French metropolitan coastline. Microphytoplankton data cover microscopic taxonomic identifications and counts. The PHYTOBS-MARCOBOLO dataset corresponds to a dataset extracted from the PHYTOBS network (DOI:10.17882/85178). The PHYTOBS network provides the scientific community and stakeholders with validated and qualified [...]

This product contains observations and gridded files from two up-to-date carbon and biogeochemistry community data products: Surface Ocean Carbon ATlas SOCATv2022 and GLobal Ocean Data Analysis Project GLODAPv2.2022. The SOCATv2022-OBS dataset contains >25 million observations of fugacity of CO2 of the surface global ocean from 1957 to early 2022. The quality control procedures are described in Bakker et al. (2016). These observations form the b [...]
