Hourly High Frequency Radar (HFR) surface current data (ocean surface velocity) from 2 different stations located on the French Mediterranean coast (Toulon), processed in real time. The total velocity is then reconstructed from the filled radial velocity files, and projected onto a cartesian grid of 1km x 1km. The HFR data comes from two systems, one monostatic radar PEY (located at Fort Peyras, La Seyne sur mer), and one bistatic POB (receiver located at Cap Bénat - Bormes les Mimosas, and transmitter on Porquerolles Island). The HFR data is initially hourly sampled. The radial velocity are processed by an algorithm of Directional of Arrival Finding with a self-calibration method developed by our laboratory.

Daily High Frequency Radar (HFR) surface current data (radial velocity files and total velocity file) from 2 different stations located on the French Mediterranean coast (Toulon), spanning from January 2012 to December 2019. The radial datasets have been processed to remove outliers. Then, the gaps in the data have been filled using the DINEOF algorithm. The total velocity is then reconstructed from the filled radial velocity files, and projected onto a cartesian grid of 1km x 1km. The HFR data comes from two systems, one monostatic radar PEY (located at Fort Peyras, La Seyne sur mer), and one bistatic POB (emitter located at Cap Bénat - Bormes les Mimosas, and transmitter on Porquerolles Island). The HFR data is initially hourly sampled. To remove the outliers of the data, for each timestep, a Probability Density Function (PDF) is computed on the spatial gradient of each radial map. Pixels with a spatial gradient with a probability under 3% are removed. Additionnally, for each pixel, a PDF is computed on the temporal gradient of its whole timeseries. Timesteps with a temporal gradient that have a probability under 1% are then removed. Then we proceed to a preliminary temporal and spatial hole filling of the missing data. For the timeseries of each pixel, timesteps that are surrounded by valid values within 3 hours (i.e. 3 timesteps) are filled by a weighted linear interpolation. For each timestep, pixels of the map surrounded by values within 1 grid point are filled in the same way. The radial data is then daily averaged. The DINEOF algorithm (http://modb.oce.ulg.ac.be/mediawiki/index.php/DINEOF) is run in a multivariate way (2 radial velocity files) using 50 EOF modes for the reconstruction. At some timesteps (shown by the flag variable of the file), the filling has not been possible, and the missing maps have been replaced by the temporal average radial map. The filled radial velocities are then locally interpolated onto a cartesian grid of 1km spatial resolution using a Weighted Least Square method.

The GeoKarla dataset gathers geophysical and petrophysical data acquired over the Karla impact structure (Tatarstan, Russia). In September 2019, a field campaign on this eroded and buried structure was performed. Magnetic and gravity field observations were done, as well as geological mapping and sampling. Further petrophysical analyses in laboratory were performed on rock samples. All these data reveal - for the first time - a clear but unusual geophysical signature of the Karla impact structure. ==== acknowledgements ====== The associated research project was funded by: Russian Foundation for Basic Research RFBR grant no.18-55-5014 CNRS PRC French program Institutes/Participants: * Aix-Marseille Université, CNRS, IRD, INRAE, Aix-en-Provence, France Quesnel, Y., Rochette, P., Gattacceca, J., Uehara, M. * Institute of Geology and Petroleum Technologies, Kazan Federal University, 4/5 Kremlyovskaya Str., 420008, Kazan, Russia Bezaeva, N.S., Kuzina, D.M., Nasyrtdinov, B.M. * V.I.

The present dataset is based on a nine site study of fine seabed topography in intertidal zones. Four coral sites (Maupiti A, B and C and Niau islands) and five rocky sites (Ars en Ré, Socoa, Parlementia A and B and Banneg island) have been explored. The data has been gathered using on-foot GNSS RTK for all sites (Trimble R8/R8S and Leica sytems) except Banneg island, where aerial Lidar data from Litto3D program has been used. The horizontal resolution varies between 3.8 and 12cm allowing to describe a wide range of spatial scales (generally over 3 spectral decades). The data has been processed to explore the statistical and spectral metrics which can be used to characterize the architectural complexity of seabeds.

L’Observatoire du milieu porté par le GIPREB (Groupement d’Intérêt Publique pour la Réhabilitation de l’Etang de Berre) a pour vocation de suivre depuis 1994 l’évolution hydrologique et biologique de l’étang de Berre (France, Méditerranée). Le suivi mis en place au sein de l’Observatoire du GIPREB répond pour l’étang de Berre aux quatre grandes problématiques que sont : - le contrôle des apports par les bassins versants, - le contrôle de l’eutrophisation, - la contamination et - le niveau de réponse des biocénoses et habitats. L’étang de Berre, d’une superficie de 155 km2 et une lagune saumâtre (qualifiée d’« eaux de transitions » au titre de la directive-cadre sur l’eau) située dans les bouches du Rhône (France) . Sa profondeur moyenne est de 6,5 mètres, pouvant atteindre 9 mètres au centre de l’étang. Elle est reliée à la mer méditerranée par le chenal de Caronte au sud et reçoit l’eau des trois rivières que sont la Touloubre, l’Arc et la Durançole. Au sud l’étang de Bolmon (en communication avec l’étang de Berre) reçoit lui les eaux de la Cadière. Ses apports du bassin versant naturel sont complétés par ceux de la chaîne hydro-électrique Durance-Verdon dont les eaux douces sont rejetées sur les rivages nord de l’étang. (CF carte). La population du bassin versant naturel (1 700 km²) de l’étang de Berre s’élève à 600 000 habitants. Les vents sont caractérisés par deux secteurs dominants : N-NW (le mistral est le vent dominant et fréquent) et S-E. L’étang de Berre constitue un milieu eutrophe avec de fréquentes efflorescences algales et des phénomènes récurrents d’appauvrissement ou de disparition de l’oxygène de ses eaux. - informations sur l'étang de Berre : https://etangdeberre.org/comprendre/generalites-sur-letang-de-berre/ Bases de données mises à disposition : ============================== - Hydrologie : • Haute Fréquence en une station (H12) depuis 2020 : S, O2, Température à trois profondeurs (surface – milieu – fond) • Prélèvement mensuel en 10 stations en surface et fond depuis 1994 : O2, NH4, NO2, NO3, PO4, SiOH4, Nt/Pt, COP/NOP, MES, Chla/Pheo • Profil de sonde mensuel en 10 stations depuis 1994 : S, O2, T°C - Espèces benthiques depuis 2002 : Prélèvement mensuel en 8 stations - Phytoplancton : Prélèvement mensuel en 2 stations - Macrophytes depuis 2001 : Comptage annuel des macrophytes sur 31 transects - Herbier de Zostère depuis 2004 : Cartographie annuelle de tous les herbiers dans l’étang (format .shp)

Maupiti ("the Stuck Twins'') is a diamond-shaped island located in the western part of the Society archipelago in French Polynesia. The present study focuses on the data recovered over a single cross-barrier transect located in the south-west barrier during the MAUPITI HOE field campaign, from 5 to 18 July 2018. The studied area is representative of the reef structure observed along the 4km-long southwestern barrier reef, showing an alongshore-uniform structure exposed to swell approaching with weak incident angles, a healthy reef colony. In the cross-barrier direction, the reef displays a clear partitioning of bottom roughness that ranges from low-crested compact structures at the reef crest to higher and sparser coral bommies on the backreef. The experimental setup was specifically designed to analyse and differentiate the dynamics over three roughness-contrasting sections found over the barrier reef. Four pressure sensors (OSS3, OSS4, OSS5, OSS6) have been deployed across the reef flat/ backreef, outside the surf zone. The bottom pressure is measured continuously at 10 Hz, and are converted into free surface elevation assuming hydrostaticity. An electrocurrent meter S4 provides the wave forcing while AQP1 is a velocity profiler providing the transports. The bed profile is obtained from the combination of (I) boat survey in the deeper part and (ii) high resolution GNSS RTK topography by feet.

The scientific objectives of the project MAUPITI HOE are to understand the hydrodynamics of an archetypal reef-lagoon system of a high volcanic reef island. The physical functioning of the hydrosystem involves a fine coupling between water levels, waves (including wind, infragravity and VLF waves), currents and seabed structure (reef roughness). The present data focuses on the reef barrier dynamics. Citation: - Sous D., Bouchette F., Certain R., Meulé S. (2021). Maupiti Hoe 2018 [Data set].
