This dataset gathers, total abundance, abundance per size class, total biomass and biomass per size class of two vulnerable fish species, the dusky grouper, Epinephelus marginatus (Lowe, 1834), and the brown meagre, Sciaena umbra Linaeus, 1758, recorded inside and outside the Marine Natural Reserve of Scandola (Corsica, NW Mediterranean) in 2012 and 2018. Fish were recorded by underwater visual censuses performed on belt transects (50 x 15 m) run parallel to the coast between 1 and 40 m depth at 13 sites according to three levels of protection status (integral reserve, buffer zone and unprotected zone). A total of 532 transects were performed in 2012 and 526 in 2018. Image Reference: https://www.seanoe.org/data/00754/86639/illustrations/illustration-134.gif.

This dataset  reports ocenanic CO2 parameters measured on discret samples collected at the SOLEMIO station (Bay of Marseille - North Western Mediterranean Sea - aprox. 65 m depth). The SOLEMIO station is part of the French national network of coastal observation SOMLIT (Service d’Observation en Milieu LITtoral – http://somlit.epoc.u-bordeaux1.fr/fr/). Measurements of carbonate chemistry parameters are not routinely measured within the framework of the SOMLIT network. This datased reports fortnightly measurements collected during three years (between june 2016 and june 2018) at three different depth in the water column (Surface, intermediate and bottom). This dataset is constituted of measurements of total alkalinity, total inorganic carbon and pH (on the total scale). Dissolved oxygen concentrations, inorganic nutrients, temperature and salinity (SOMLIT core parameters) are also reported.

EMSO is a European network of seabed and fixed-point water column observatories whose scientific objective is to acquire long time series in the seas around Europe for the study of environmental processes related to interactions between geosphere, biosphere and hydrosphere. MAREGAMI project (MARine Earthquake Gap Assessment and Monitoring for Istanbul) is a bilateral Turkish-French collaborative project coordinated by IFREMER and Istanbul Technical University and funded by ANR and TÜBITAK. The goal of MAREGAMI was the development of new methods and monitoring strategies to assess earthquake and tsunami risks related to offshore faults, with tasks: (1) Marine geodesy: acquisition and processing of geodetic submarine data, (2) Hydrodynamics and specific depositional processes: water column data acquisition and hydrodynamic modeling, (3) Improving earthquake relocation with ocean bottom instruments, (4) Designing an optimal and sustainable network of submarine sensors. Data distributed here were acquired for MAREGAMI Task 2.  These consist of time series acquired during 4 deployments on the sealfoor perfomed between January 2018 and November 2020 of an instrumented frame holding a RBR bottom pressure recorder (BPR) and a Seaguard recording current meter (RCM) equipped with additional sensors (conductivity, oxygen, tide pressure end temperature). The acquisition and distribution of marine data time series in the Sea of Marmara is funded by EMSO-France Research Infrastructure, EMSO-Link, and MAREGAMI projet. DT-INSU provided operational support and instrumentation.
