Ocean-ice data from an Antarctic ice shelf water plume flowing beneath land-fast sea ice

Data from a measurement campaign examining the oceanic connection between an ice shelf cavity and sea ice. Here we present data from the ocean boundary-layer in an Ice Shelf Water outflow region from the Ross/McMurdo Ice Shelves. From a fast ice field camp during the Spring of 2015, we captured the kinematics of free-floating relatively large (in some cases 10s of mm in scale) ice crystals that were advecting and then settling upwards in a depositional layer on the sea ice underside (SIPL, sub-ice platelet layer). Simultaneously, we measured the background oceanic temperature, salinity, currents and turbulence structure. At the camp location the total water depth was 536 m, with the uppermost 50 m of the water column being in-situ super-cooled. Tidal flow speeds had an amplitude of around 0.1 m s-1 with dissipation rates in the under-ice boundary layer measured to be up to e=10-6 W kg-1. Acoustic sampling (200 kHz) identified backscatter from large, individually identifiable suspended crystals associated with crystal sizes larger than normally described as frazil. Crystal sizes in the SIPL were also measured.

ROV3G 2021 database: geophysical data on the continental shelf offshore Santo Stefano al Mare and San Lorenzo al mare, Liguria, Italy.

ROV3G scientific cruise is dedicated to the morpho-tectonic study of the ligurian shelf, through the acquisition of bathymetric data and optical images with HROV Ariane. This cruise took place on R/V Europe in october 2021, and constituted a pedagogic project for the students of  Master 3G Recherche, Géologie et Géophysique, of Université Côte d'Azur (UCA), attached to Géoazur lab. The M2 students were in charge of the scientific project, they determined the goals of the cruise, took part in the acquisition and interpretation of the data.  During the 3 days cruise, we acquired bathymetric data at shallow depth on the continental shelf offshore Santo Stefano al Mare and San Lorenzo al Mare, along the Ligurian coast. The bathymetry on the continental shelf exhibits morphologies that are probably related to the Flyschs formation that is outcroping onshore (Stani et al., 2010), and that is partially capped by late quaternary deposits (as identified in seismic data and interpreted in Bozzano et al., 2006). Ridges identified as paleo-shorelines (paleo-beaches?) have been investigated with HROV ariane whose navigation is also published here. Videos are available on video.ifremer.fr Here we publish two bathymetric grids at high-resolution, calculated from the ME70 multibeam echosounder of R/V Europe, using GLOBE software (Poncelet et al., 2022). The shallowest part of the plateau is gridded in a 5 m digital elevation model (DEM), while the entire survey area is gridded at 10m resolution. The back-scatter maps, gridded at 6 m, produced with Sonarscope software (Augustin et al., 2022), are also available (raw and compensated). All grids are in WGS84 (EPSG:4326). The cruise report (written in french) is also available.

Dissolved cobalt and manganese in the East China Sea

This dataset describes the dissolved cobalt and manganese distributions in the East China Sea. Other parameters such as salinity, water temperature, potential density, dissolved oxygen, and nutrient (nitrate, phosphate, and silicate) concentrations are also included. Seawater samples used for generating this dataset were obtained during the KS-15-6 cruise onboard R/V Shinsei Maru between July and August 2015 (Stn1 to Stn15), and during the KH-15-3 cruise onboard R/V Hakuho Maru in October 2015 (F1, D4, B8, and I1). Dissolved cobalt concentrations were determined using cathodic stripping voltammetry at the University of Tokyo and by using inductively coupled plasma - mass spectrometry (ICP-MS) at Kanazawa University, Japan. Meanwhile, dissolved manganese concentrations were determined using ICP-MS at both the University of Tokyo and Kanazawa University. All samples were irradiated with ultraviolet light before analysis.

Seagrass Meadows in The Greek Seas

Combined use of optical (satellite imagery), and acoustic (sidescan sonar) remote sensing techniques, as well as in situ methodologies (visual census; SCUBA diving, Towed Underwater Cameras, and Remotely Operated Vehicles) was employed to map the spatial distribution of seagrass habitats in the coastal waters of the Hellenic territory. Seagrass meadows were recorded at approximately 70% of the Hellenic coastline (Eastern Ionian, Aegean and Levantine Seas), and their surface area exceeded 2,673.1 km2. Posidonia oceanica is -by far- the dominant seagrass species of the Hellenic seas, covering the vast majority of seabed at depths between the shoreline and 25 – 30 m (or deeper in insular areas), followed by the species Cymodocea nodosa, Zostera noltei, and Halophila stipulacea, which, however, presenting local presence and limited areal extent. Habitat suitability in terms of the seabed spatial extent that is available for the growth of seagrass meadows (i.e., the spatial extent of coastal areas between the shoreline and the isobath of 20m) and the seawater clarity conditions are highlighted as the critical factors for the formation of well-structured and extensive meadows. The results of this study are of great importance and usefulness for the effective management and conservation of valuable marine ecosystems.

Marine Meteorological Data from R/V Miguel Oliver, 2016

The R/V Miguel Oliver was built in 2007 for scientific fisheries assessment and oceanographic research purposes. Owned by the Spanish General Secretariat of Fisheries, it mainly operates around the Iberian Peninsula and Canary Islands waters. Equipped with an automatic weather station, collected data are daily sent to the Spanish Institute of Oceanography (IEO) Data Center / National Oceanographic Data Center (NODC) for delayed-mode quality control and long-term archive and dissemination. Recently, a semi-automatic process has been used to perform quality control and data assessment. The quality controlled data have been stored in MEDAR/MEDATLAS format, and the corresponding quality flag has been added to each individual measurement. This facilitates their reuse for different purposes, from climatology or academic studies to industrial sector needs, among others. In 2016, air temperature, relative humidity, wind speed and direction and solar radiation were collected.

COAST-HF - SCENES station dataset from 2015 to 2022 - environmental parameters

The SCENES monitoring station is part of the SNO COAST-HF national network (ILICO-RI), and the regional PHRESQUES observation network. The station includes i) a surface buoy equipped with a CTD and an optical turbidity and fluorescence sensor measuring approximately 1.5m below surface and ii) a benthic station equipped with an optical turbidity sensor and an up-looking ADCP (before Oct. 2017 – optical sensor ~ 1.4m above the bed, after Oct. 2017 : 0.5m above the bed). Due to technical problems, the time series, for all sensors, is discontinuous. Optical turbidity measurements can be transformed in suspended particulate matter concentration (SPMC, in g/l) using a calibration relationship built from the PHRESQUES field campaigns (SPMC=0.00156*NTU+0.001). The acoustic backscatter signal was processed to retrieve SPMC values using optical turbidity sensors and observations from the PHRESQUES Field campaigns.  This dataset allows to investigate hydrodynamics and sediment dynamics from the tidal scale to the seasonal and interannual scale from water level, current velocity, salinity, temperature and SPM concentration measurements. Please refer to associated publications.

Intermediate ocean circulation and cryosphere dynamics in the northeast Atlantic during Heinrich Stadials: benthic foraminiferal assemblage response

The interaction between ocean circulation and ice-sheet dynamics plays a key role in the Quaternary climate. Compared to the surface and deep compartments of the Atlantic Meridional Overturning Circulation (AMOC), the study of intermediate depths during key time periods, such as Heinrich Stadials (HSs), remains poorly documented, especially in the Northeast Atlantic. Here we use benthic foraminiferal assemblage data to trace paleoenvironmental changes from ~32 to 14 ka cal BP at ~1000 m depth in the Bay of Biscay. Our results highlight the high sensitivity of benthic foraminifera, with species-specific responses, to continental (European Ice Sheet dynamics) and marine (AMOC) forcing factors during the last three HSs. In general, HSs were characterized by the concomitant presence of meso-oligotrophic and anoxia indicator species and the low abundance of high-energy indicator species. This confirms an overall sluggish intermediate circulation during the three HSs in the Northeast Atlantic. HS1 is distinctive by the abundance of high-organic flux indicator species during its early phase. This is consistent with the fact that HS1 was, by far, the most important period of ice-sheet retreat and meltwater release to the ocean over the studied time interval. Finally, foraminifera depict the mid-HS2 re-ventilation event due to regional glacier instabilities.

IPOCOM project: CTD data along the French Mediterranean coast, NW Mediterranean, spring 2024.

This dataset contains the CTD data collected during the IPOCOM project (Fish inventory using environmental DNA), between 21/05/2024 and 10/06/2024, along the French Mediterranean coast (PACA and Occitanie regions), jointly by the (MARBEC MARine Biodiversity, Exploitation and Conservation)-[http://www.umr-marbec.fr/en/?lang=en] (France) teams. The CTD data were obtained using RBR concerto3 autonomous logger from Victoria IV trimaran belonging to Scopra, France and chartered by the University of Montpellier. 133 transects (1 was 2.5-km long and 132 were 5-km long) were performed along the deepest local limit of the Posidonia oceanica seagrass meadow from Menton to Cerbère, latitude 42.3-43.9°N and longitude 2.7-7.6°E. In PACA, the sampling depth was -26 m in mean (±10 m) and in Occitanie the mean depth was -7 m (±5 m), 5 m above the seabed in mean for both regions. The sensors measured and recorded conductivity (mS/cm), temperature (°C), pressure (dBar), dissolved O2 concentration (µmol/L) and turbidity (NTU). Other parameters were derived from the previous measurements: sea pressure (dbar) removing atmospheric pressure, depth (m) simplifying and using density parameter, salinity (PSU) or Practical Salinity Scale (PSS-78), speed of sound (m/s) based on UNESCO algorithm, specific conductivity (µS/cm) and dissolved O2 saturation (%). All parameters were measured or calculated at depths ranging from – 0.5 m to -56 m (Table 1). Recordings were made every 0.5 seconds (2 Hz frequency). The accuracy, specified by the manufacturer, was ±0.003mS/cm for conductivity, ±0.002°C for temperature, ±0,1 dbar for pressure (Depth), a maximum of ±2µmol/L or ±1.5% for dissolved O2 concentration and saturation. RBR Concerto3 was factory calibrated before. The downloadable files are a csv of CTD probe data, a geopackage of all transects spatialized with mean, min, max, sd and median for all parameters of CTD probe, a pdf showing the evolution of all the variables, accompanied by a text explaining the problems encountered.

Census of Marine Malacofauna of the Italian Coasts

The census of the Italian marine malacofauna took shape in 1982 by a group of researchers: Daniele Bedulli, Bruno Dell'Angelo, Piero Piani and Gianni Spada with a publication in the Bollettino di Malacologia (Bedulli D., Dell'Angelo B., Piani P., Spada G. 1982. Project for the census of the Italian marine malacofauna. Bollettino Malacologico, 18, 85-94). Subsequently, Filippo Bassignani, Vincenzo Iacono and Bruno Sabelli collaborated on the project, as well as 93 collectors. The Census of the Italian Marine Malacofauna was a research project by the S.I.M. (Italian Society of Malacology) coordinated by Prof. D. Bedulli of the Department of Evolutionary and Functional Biology of the University of Parma. The project was conceived to increase and organize knowledge on the distribution of marine molluscs of the Italian coasts. This research was necessary because knowledge on the biogeography of the Mediterranean was quantitatively scarce and highlighted a lack of biogeographic data. The aim of the research was to create a database of marine molluscs present on the Italian coasts and their density. Each piece of data (presence and density of a species) is completed by some environmental parameters (e.g. depth, environment, type of substrate, etc.). The main objective of this census was to study the qualitative composition of the coastal malacocenoses of the Italian peninsula and to determine the biogeographic distribution patterns of the different mollusc species, to identify the Lessepsian migrations and the anthropochoric introductions.The data were obtained through a coordinated system of collectors, as well as using the results of various campaigns conducted by research institutions such as: Universities, ENEA, etc. The data collected were checked by SIM "trustees" especially with regard to the systematics. These data come from the old ENEA database, managed by the S. Teresa Centre of ENEA, which collected the data of The Census of the Italian Marine Malacofauna.

Trophic ecology and nutritional status of northern shrimp in Canada's sub-Arctic

In the Northwest Atlantic, Pandalus borealis (northern shrimp) serve as key mid-trophic consumers and prey for higher-trophic predators, including commercially important fish species. However, the impact of changing environmental conditions on trophic interactions and lipid storage in sub-Arctic ecosystems is not well understood. We employed biochemical tracers (fatty acids and stable isotopes) to investigate the trophic ecology and stage-specific nutritional condition of P. borealis across spatial and seasonal scales. A total of 68 different fatty acids (FAs) were identified in P. borealis tissues (i.e., muscle and eggs). The relative abundances of these FAs varied among sex, tissues, seasons, and fishing areas. Results revealed that P. borealis primarily fed on diatoms and zooplankton, with opportunistic feeding on sinking phytodetritus. Lipid composition showed strong seasonality, with storage triacylglycerols being the predominant lipid class. Ovigerous females exhibited the highest lipid concentrations and essential fatty acids, emphasizing the ecological importance of eggs as high-quality lipid sources. Additionally, total lipid content in eggs increased from spring to summer, highlighting vulnerability to shifts in seasonal primary production. This study underscores the significant seasonal variability in the nutritional status of P. borealis and the need to understand lipid dynamics to assess population resilience to environmental changes.

Near-seafloor hydrodynamic data in the western Gulf of Lion, 1 Nov 2012-15 April 2014

Extreme percentiles (1%, 5%, 95%, 99%) of bottom temperature and salinity, as well as (95%, 99%) of bottom currents, were modeled using SYMPHONIE on a numerical domain covering 65 × 60 km at a resolution of 80 m. The 10-m bathymetry used inside the Lacaze-Duthiers Canyon was collected during the CALADU_2021 cruise (https://doi.org/10.17600/18001575). Statistics of extreme values were derived from hourly fields simulated between November 1, 2012, and April 15, 2014. This period includes two contrasting winters: the winter of 2012–2013, which was cold with dense water cascading, and the winter of 2013–2014, which was warm. This dataset was produced to assess the probable distribution of habitats (habitat suitability modeling) for cold-water corals in the Lacaze-Duthiers Canyon at different resolutions as part of the European H2020 project REDRESS (Restoration of Deep-Sea Habitats to Rebuild European Seas, https://redress-project.eu/, Grant Agreement No. 101135492). SYMPHONIE is a component of the national service SIROCCO (research infrastructure ILICO). This dataset is related to the article "Mapping and Conservation of Cold-Water Corals in the Lacaze-Duthiers Canyon for Transboundary Management", submitted to Mediterranean Marine Science by Fabri et al. in 2025.
