A global monthly climatology of the mixed layer depth (MLD), obtained with a physically derived and energy-based methodology (EBM), is provided. This climatology defines the mixed layer as the energetically homogeneous upper ocean layer in which water parcels can move with little or no buoyancy work; the mixed layer is representative of seasonal timescales, without addressing the diurnal mixing cycle or the timescales in which mixing is currently [...]
The Floating Marine Litter (FML) Dataset comprises approximately 5500 floating marine litter optical images and 14000 bounding box annotations, tailored for the object detection task. The images were taken from a first-person perspective using a camera mounted on an Unmanned Surface Vehicle (USV). The images were collected in diverse lighting conditions and camera setups across inland and coastal water bodies.
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) [...]
