This dataset presents the concentrations of chemical contaminants of emerging concern (CECs) in common dolphins (Delphinus delphis) from the Bay of Biscay (NE Atlantic). Tissue samples of liver and blubber were collected on a total of 61 individuals between 2000 and 2023. These individuals encompass 51 stranded animals recovered by local stranding networks and 9 bycaught individuals directly observed on board (dead animals). The targeted CECs inc [...]
Organismal communities associated with coral reefs, particularly invertebrates and microbes, play crucial roles in ecosystem maintenance and coral health. Here, we characterized the organismal composition of a healthy, non-urbanized reef (Site A) and a degraded, urbanized reef (Site B) in the Red Sea to assess its impact on coral health and physiology. Biomimetically designed terracotta tiles were conditioned for 6 months at both sites, then reci [...]
Coral assemblages were reconstructed in 3 dimensions (photogrammetry) using the 'Structure from motion' technique, at several locations in the canyon. The two colonial species, M. oculata and D. pertusum, were located on georeferenced photogrammetric models, with geographic coordinates and depths. The size distribution of both species was measured on photogrammetric models. Population size structure Number of coral colonies measured = 5387 (COV [...]

The two colonial species, M. oculata and D. pertusum, were located on georeferenced photogrammetric models, with geographic coordinates and depths. Spatial and vertical distribution of the two coral species Coral colonies were observed at different depths, D. pertusum between 339 and 254 m, M. ocu [...]
As part of the MACCO research project (https://www.macco.fr), we developped an ISIS-Fish database (Mahevas et al 2004, Pelletier et al 2009, https://isis-fish.org) describing the mixed demersal fishery in the Bay of Biscay. For this application, the spatial extent of the fishery is the Bay of Biscay, defined here by ICES divisions 8a, 8b and 8d and the resolution chosen is 1/16 ICES statistical rectangle. The period modeled is 2015-2022, with a m [...]
This dataset contains temperature data acquired between July 2023 and June 2024 using 5 thermocrons i-buttons © installed along chains nearby the SMOOVE camera connected the SeaMoN East frame. Data was acquired every hour. The array is not connected to an energy node. They are associated with the SMOOVE camera which is part of the SeaMoN East ecological monitoring node. Location : N 37°17.334, W 32°16.534, 1692 m
This dataset consists of a quantitative imaging dataset of FlowCam-imaged microplankton (> 20 µm), collected with the Deck Net during the Tara Pacific Expedition (2016-2018). Samples were collected at the surface, generally on a daily frequency, across the Atlantic and Pacific Oceans from open-ocean stations (142 samples; open-ocean label: [i00_oa###]) and from stations in coastal waters of 32 Pacific islands (62 samples; island label: [i##_oa### [...]
This dataset consists of a quantitative imaging dataset of FlowCam-imaged microplankton (> 20 µm), collected with the Bongo nets by scuba divers using an underwater scooter during the Tara Pacific Expedition (2016-2018). Samples were taken from the surface, near reefs and lagoons in the Pacific (37 samples). The full description and discussion of this dataset can be found in the associated data paper Mériguet et al. (in rev). This dataset consis [...]
In the context of the MACCO project (https://www.macco.fr/), we have developed an ISIS-Fish database with the objective of describing the spatial and monthly life cycle of 7 fish species of commercial interest in the mixed demersal fishery in the Bay of Biscay. In the case of megrim, cuckoo skate, thornback skate, anglerfish and sole, the population dynamics have been described in detail, both by age class and by global model. In addition, the di [...]
This IGA-HP Gravelines dataset includes long-term time series on marine phytoplankton, zooplankton, and hydrological data from 1978 onward at the coastal station named “canal d’Amenée” (in French) near the Gravelines Nuclear Power Plant located in the southern bight of the North Sea, near the Dover Strait (eastern English Channel). Phytoplankton data essentially cover microscopic taxonomic identifications and counts (cells.l-1), and pigment conce [...]
