Description In this study, we analyzed the haline tolerance of the stomatopod (Crustacea) larvae collected in an estuary from the southern Gulf of Mexico. The chosen study area was the Sontecomapan lagoon, which shows great variability in the salinity gradient throughout the year. The Sontecomapan estuary was visited five times (June 2018, October 2019, May 2021, November 2021, and June 2022) and zooplankton samples were collected with a conical [...]

The MesuRho station is a multi-parameter observing platform located at the Rhone River mouth and installed on a navigation buoy, Roustan Est. It is dedicated to the study of trends and impacts of extreme events (floods, storms, heat waves) on hydrology, currents, biogeochemistry and sedimentary dynamics. During the period 2009-2021, the station was located 2,5km away from the river (43.1913°N, 4.5197°E), where the averaged water depth evolved fr [...]

Pearl oysters, Pinctada margaritifera, were exposed to 15 pH conditions ranging from 8.0 to 6.6, for 16 days, in order to determine their reaction norms to ocean acidification at all physiological scales, from the gene to the organism. The following physiological parameters were monitored: survival, byssus, ingestion, calcification, shell, periostracum, carbohydrate reserves, carbonic anhydrase activity, fatty acid composition of cell membranes, [...]

Zooplankton was collected at 34 stations in the Chaun Bay, an enclosed bay of the East Siberian Sea (Arctic Ocean), during the 60th cruise of the RV "Akademik Oparin". Sampling was conducted between 9 and 21 October 2020 by Daria A. Yurikova, Glafira Kolbasova, and Vitaly L. Syomin (IORAS). Up to two depth layers were sampled vertically at each station using a Juday net with a mesh size of 180 microns and a mouth opening of 0.1 square meters. One [...]

Seagrass ecosystems rank among the most productive marine environments on the planet, hosting high cycling rates of a range of globally relevant elemental cycles. While the cycling of reactive oxygen species (ROS) may have important links with other redox-related biogeochemical cycles (i.e. trace metals, carbon, nitrogen, and oxygen), the dynamics of ROS in seagrass ecosystems are poorly characterized. To assess the flux, decay rate, and fate of [...]

The COAST-HF-BESSète station is a part of the French monitoring network COAST-HF (Coastal OceAn observing SysTem – High Frequency, http://coast-hf.fr/) accredited by the French Centre National de la Recherche Scientifique (CNRS) as a National Observatory System (SNO). The main objective aims to understand and analyze evolution at different temporal scales of the coastal environment, ranging from the dynamics of extreme or transient events develop [...]

The bay of Villefranche-sur-Mer (French Riviera) is a medium-sized bay (2 miles long by 0.8 wide) characterized by great depth (> 300 m at its mouth) and the absence of a continental shelf. It is sheltered from the prevailing east and west winds This oligotrophic to mesotrophic site is located in a highly urbanized area, subjected to seasonal anthropogenic influences: cruise ships, intense yachts traffic, increases of population. The Roya (26 km [...]

The COAST-HF/Arcachon-Ferret time series characterizes the hydrology of the interface between the Arcachon lagoon, located in the South-Western France, and the Atlantic Ocean. A buoy belonging to Phares et Balises is instrumented with a multi-parametric probe that records sub-surface temperature, conductivity, depth, turbidity and fluorescence every 10 minutes since February 2018. It is opérated by the OASU and EPOC teams (Univ. Bordeaux/CNRS). [...]

"55 drifters were deployed along two zonal transects centered at 47 and 47.25ºS on September 8, 2021(Fig. 1). Spacing between the initial deployment positions of the drifters varied between 14 km and 18 km in the continental shelf providing the position every 30 minutes and between 3 km and 6 km over the continental slope with temporal resolution of 10 minutes. The shortest distances between deployment positions correspond to drifters deployed cl [...]
