he Reykjanes Ridge is a major topographic feature of the North-Atlantic Ocean. It lies in a central position along the main paths followed by the upper and lower limbs of the Meridional Overturning Cell (MOC), which contributes at moderating the European climate in creating a transport of heat toward the North Atlantic. Our hypothesis is that the Reykjanes Ridge influences the main components of the upper and lower limbs of the MOC because it is [...]
This dataset contains mesoscale eddies from the Ocean Eddy Detection and Tracking Algorithms (TOEddies) Atlas colocated with Argo profiling floats. Applied to daily gridded maps of satellite Absolute Dynamic Topography, TOEddies provides information on eddy dynamical characteristics (e.g., size and intensity) over a 30+ year period (1993–2023) and identifies complex eddy-eddy interactions that lead to eddy splitting and merging. Furthermore, thes [...]
The northern Gulf of Mexico (nGoM) experiences seasonal coastal hypoxia due to nutrient enrichment from the Mississippi-Atchafalaya River basin, leading to one of the world’s largest hypoxic zones. In these shallow zones, benthic processes play an essential role in driving/maintaining deoxygenation and acidification of bottom waters. This dataset investigates carbonate dissolution processes in surface sediment interface of the nGoM during hypoxic [...]
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 [...]
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. 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### [...]
