Due to climate change, the frequency and intensity of extreme rainfall events are increasing in the Mediterranean region. As a result, terrestrial runoffs are expected to occur more frequently in the future, potentially impacting coastal aquatic ecosystems.The aim of this study was to assess the effects of a simulated terrestrial runoff on all components of the planktonic food web.In May 2021, an in situ mesocosm experiment was conducted in the M [...]
The Calvi Bay is a low-runoff system located on the western coast of Corsica. It opens to the north to the Ligurian Sea, one of the main sub-basins of the Northwestern Mediterranean Sea. This dataset contains long-term time series (2012 - 2020) of high-performance liquid chromatography (HPLC) phytoplankton pigment concentrations measured at the Canyon head station, a station located in the outer part of the Calvi Bay. The pigments measured (in ng [...]
In October 2020, the LaMMA Consortium carried out a field measurement campaign in the Southern Ligurian Sea (SLS) as part of the DDR20 – Drifter Demonstration and Research 2020 experiment. Organized by CMRE and supported by several EU-funded projects (SICOMAR plus, JERICO-S3, SINAPSI, and IMPACT), the campaign focused on the deployment of CODE drifters (Davis, 1985; Poulain, 1999). The drifters used were specifically acquired by LaMMA through the [...]
To assess the pressures exerted by scientific research at the Lucky Strike vent field, we compiled a comprehensive inventory of all research activities conducted from 1992 to 2024. These activities included sampling, in situ measurements, mooring deployments, submersible dives, and litter deposition on the seafloor. The type of sampling activities was identified (i.e., biological, rock, sediment, fluid) to evaluate their respective pressures. Lit [...]
Subsurface temperatures from Tromelin island, from 2019 to 2024. The data-loggers used were HOBO Water Temperature Pro v2 Data Logger (U22) developped by Onset.
This dataset comprises multibeam bathymetry and very high resolution seismic data acquired over the Lansdowne Bank (New Caledonia, SW Pacific), during the SEDLAB cruise. The latter was a 29 day research cruise on the French national fleet ship R/V ALIS that took place in April and May 2018. The main aim was to characterise the sedimentary dynamics and the stratigraphic architecture of the Lansdowne Bank, a partly drowned, isolated rimmed carbonat [...]
This repository contains marine data on temperature, dissolved oxygen, pressure, practical salinity, density, conductivity, current speed and direction, total alkalinity, total scale pH measured at four coastal stations in the Gulf of La Spezia (Eastern Ligurian Sea): 1. Santa Teresa Bay (STB, 44.081871°N, 9.881686°E) (depth: 1 m) leisure marina inside the dam; 2. Mussel Aquaculture station (MUS, 44.079140°N, 9.874360°E) (depth: 5 m) inside the h [...]
The mass spawning of Porites rus, a scleractinian coral, was monitored between 2014 and 2023 in the South Pacific and South Indian Oceans using citizen science approaches. Two datasets were compiled: one at the reef site level, which recorded the spawning time of the first Porites rus colony to spawn at each site (2014-2023); and a second at the colony level, which recorded the spawning times of tagged colonies within monitoring sites (2021-2023) [...]
The Sintra hydrothermal vent site reconstructed in this dataset is 311.82 m². It is located in the North east of the main Lucky Strike Hydrothermal Vent Field (LSHF). The edifice has been surveyed with the remotely operated vehicle Victor6000 for inter-annual monitoring during the 2023 Momarsat cruise. Video transects were collected during dive 844-6 with a forward-looking camera and video sequences were used to build a 3D model of the edifice us [...]
The Capelinhos hydrothermal vent site is a large edifice of 588 m² from its base. Located off axis, 1.5 km east of the central lava lake of the main Lucky Strike Hydrothermal Vent Field (mLSHVF), it is characterised by distinct geochemical and thermal conditions from the others mLSHVF edifices, with notably high iron concentrations compared to sites around the lava lake. The edifice has been surveyed with the remotely operated vehicle Victor6000 [...]
