A comprehensive and updated compilation of the seismic stratigraphy markers in the Western Mediterranean Sea

[Lien vers la fiche source] The Western Mediterranean Sea is a natural laboratory to address questions about the formation and evolution of continental margins and the relationship between surface and deep processes. The evaporites deposited during the late Miocene’s Messinian Salinity Crisis (MSC) strongly impact its sedimentological and geomorphological evolution. Hereafter, we present a compilation of some of the main regional seismic stratigraphic markers throughout the Western Mediterranean Sea. We provide in xyz format (z in second twt) the original, not interpolated, points interpretation of the following horizons: i) Acoustic basement, ii) Base and Top of the MSC salt, also known as Mobile Unit (MU), iii) base Pliocene and iv) Seafloor. The available reflection seismic dataset, coming from a collaboration between French, Spanish, Algerian and Italian research institutes, covers most of the Western Mediterranean sub-basins with the exception of the Ligurian Basin. This compilation is currently the most comprehensive and updated available in literature and provides a useful contribution to the scientific community working in sedimentary, tectonics and geodynamics studies in the Western Mediterranean Sea.
Consistently dated Atlantic sediment cores over the last 40 thousand years

[Lien vers la fiche source] Rapid changes in ocean circulation and climate have been observed in marine-sediment and ice cores over the last glacial period and deglaciation, highlighting the non-linear character of the climate system and underlining the possibility of rapid climate shifts in response to anthropogenic greenhouse gas forcing. To date, these rapid changes in climate and ocean circulation are still not fully explained. One obstacle hindering progress in our understanding of the interactions between past ocean circulation and climate changes is the difficulty of accurately dating marine cores. Here, we present a set of 92 marine sediment cores from the Atlantic Ocean for which we have established age-depth models that are consistent with the Greenland GICC05 ice core chronology, and computed the associated dating uncertainties, using a new deposition modeling technique. This is the first set of consistently dated marine sediment cores enabling paleoclimate scientists to evaluate leads/lags between circulation and climate changes over vast regions of the Atlantic Ocean. Moreover, this data set is of direct use in paleoclimate modeling studies.

Labeled SAR imagery dataset of ten geophysical phenomena from Sentinel-1 wave mode (TenGeoP-SARwv)

[Lien vers la fiche source] The TenGeoP-SARwv dataset is established based on the acquisitions of Sentinel-1A wave mode (WV) in VV polarization. This dataset consists of more than 37,000 SAR vignettes divided into ten defined geophysical categories, including both oceanic and meteorologic features. These images cover the entire open ocean and are manually selected from Sentinel-1A WV acquisitions in 2016. For each image, only one prevalent geophysical phenomena with its prescribed signature and texture is selected for labeling. The SAR images are processed into a quick-look image provided in the formats of PNG and GeoTIFF as well as the associated labels. They are convenient for both visual inspection and machine-learning-based methods exploitation. The proposed dataset is the first one involving different oceanic or atmospheric phenomena over the open ocean. It seeks to foster the development of strategies or approaches for massive ocean SAR image analysis. A key objective is to allow exploiting the full potential of Sentinel-1 WV SAR acquisitions, which are about 60,000 images per satellite per month and freely available. Such a dataset may be of value to a wide range of users and communities in deep learning, remote sensing, oceanography, and meteorology

Boundary Layer Turbulence and Abyssal Recipes (BLT): Microstructure and Dye Survey Datasets

[Lien vers la fiche source] These data were collected as part of the Boundary Layer Turbulence and Abyssal Recipes (BLT Recipes) Experiment which focused on near-bottom processes within a continental slope canyon on the eastern side of the Rockall Trough, off Ireland. These datasets contain mooring and profiler data from dye and microstructure surveys conducted in June/July 2021 and August 2022. A fluorescein dye release was measured using the Fast CTD, a tethered profiler with a Seabird SBE49 CTD, a custom micro-conductivity probe, a Turner C-FLUOR fluorometer and an altimeter. We also conducted 5 microstructure turbulence stations using the epsi-fish profiler which measured temperature, pressure and salinity from a Seabird 49 CTD, height above bottom from a custom altimeter and kinetic energy and thermal dissipation rates measured from airfoil and thermistor probes, respectively. A McLane Moored Profiler was deployed for one week during the dye release and was outfitted with a Seabird SBE52 CTD, a Falmouth Scientific Inc. acoustic current meter, a Turner C-FLUOR fluorometer and two thermistor probes. The McLane Moored Profiler was re-deployed, without the fluorometer and thermistor probes until October 2021. In August 2022, another 6 microstructure stations were conducted with the epsi-fish profiler.

COAST-HF - data and metadata from the MOLIT buoy in the Vilaine Bay

[Lien vers la fiche source] The MOLIT (Mer Ouverte LITorale) measuring station developed and implemented by Ifremer (French Research Institute for Exploitation of the sea) is a moored buoy equipped with biological and physico-chemical sensors working in continuous and autonomous conditions. The system is located South of Brittany in the Vilaine Bay, one of the areas of the Atlantic coast most threatened by eutrophication. The buoy was deployed during the period of primary productivity, from March to October from 2011 to 2017 and has been deployed throughout the year since March 2018. The measuring station is equipped with high performance systems for seawater analysis and near real time data transmission. This station performs measurements at two levels : subsurface = LEVEL1 and bottom (1 m above the water-sediment interface) = LEVEL3. This system records with a high frequency resolution (one hour), the following parameters : sea temperature (TEMP), practical salinity (PSAL), dissolved oxygen (MASS DOXY), turbidity (TUR4) and fluorescence (FLU3). Some fluorescence data has been corrected and appears in the “fluorescence adjusted” parameter (FLU3 ADJUSTED). Dissolved oxygen measurements are compensated for temperature and salinity. This system also records with a high frequency resolution (20 minutes), the following parameters : air temperature in dry bulb (DRYT), gust wind speed (GSPD), gust wind from direction relative true north (GDIR), horizontal wind speed (WSPD), wind from direction relative true north (WDIR), surface incoming photosynthetic active radiation (LGH4). The data were qualified into several levels : 0-No QC performed, 1-Good data, 2-Probably good data, 3-Probably bad data, 4-Bad data, 5-Value changed, 7-Nominal value, 8-Interpolated value, 9-Missing value. The quality level is indicated in the data file in a column “QC” for each parameter. The information that led to the quality level are synthesized in an annual report qualification. Precision estimated of the complete data collection process is : temperature (±0.1°C), conductivity (±0.3mS/cm), in vivo fluorescence (±10%), turbidity (±10%), dissolved oxygen (0.2 mg/L). The MOLIT station is a component of the national high frequency observing network COAST-HF from the ILICO research infrastructure.
Error variance-covariance, trends, accelerations and uncertainties of regional mean sea level estimated from satellite altimetry

[Lien vers la fiche source] Satellite altimetry missions provide a quasi-global synoptic view of sea level over more than 25 years. The satellite altimetry constellation is used to build sea level maps and regional sea level indicators such as trends and accelerations. Estimating realistic uncertainties on these quantities is crucial to address some current climate science questions such as climate change detection and attribution or regional sea level budget closure for example. Previous studies have estimated the uncertainty for the global mean sea level (GMSL), but no uncertainty information is available at regional scales. In this study we estimate a regional satellite altimetry error budget and use it to derive maps of confidence intervals for local sea rise rates and accelerations. We analyze 27 years of satellite altimetry maps and derive the satellite altimetry error variance-covariance matrix at each grid point, prior to the estimation of confidence intervals on local trends and accelerations at the 90% confidence level using extended least squares estimators. Over 1993–2019, we find that the average local sea level trend uncertainty is 0.83 mm.yr-1 with local values ranging from 0.78 to 1.22 mm.yr-1. For accelerations, uncertainties range from 0.057 to 0.12 mm.yr-2, with a mean value of 0.063 mm.yr-2.

Momentum balance over the Socoa rocky platform, France

[Lien vers la fiche source] The database displays the field measurements recover during a one-week experiment in October 2021 on the Socoa's rocky platform, France. The general objective of the study was to evaluate the momentum balance over the rocky platform, in particular to quantifiy the combined effect of high seabed roughness and waves on the coupling between circulation, wave force and mean water level. The analysis is performed along a single cross-shore transect. The data include: - the cross-shore bathymetric profile - the time-series of integrated wave parameters, local mean water depth and wave-averaged currents over successive 30-min bursts - the depth- and wave-averaged momentum fluxes following the formulation proposed by Smith 2006 and Bruneau et al. 2011. The fluxes are median values obtained over significant wave height to depth ratio bins
COAST-HF - SCENES station dataset from 2015 to 2022 - environmental parameters

[Lien vers la fiche source] 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.
