Chemical data from water samples taken in Mersin Bay in 2022 in framework of the project "Ecosystem Based Monitoring and Management Plan for the Clean Mediterranean, Phase 1"

Particulate matter and particulate organic carbon concentrations (PMC and POC, respectively) in the frame of HERMES project

This data set contains underway Ferrybox data collected by an OceanPack by SubCTech during the MedSHIP cruise TAlPro2022 (on the Belgia vessel RV BELGICA) in the Western Mediterranean Sea in May 2022.

Part of Deliverable 6.1 of GENIALG Project. Datasets used for parametrisation and validation of models and evaluation of farm footprint. The dataset consists of continuous and spot sampling records of temperature, salinity (conductivity), turbidity, Secchi disk depths, irradiance (as PAR), nutrients and suspended matter content in water samples. Records obtain at Ventry Harbour test farm between September 2017 and October 2019 during GENIALG project (project ID: 727892, GENIALG - GENetic diversity exploitation for Innovative Macro-ALGal biorefinery, http://genialgproject.eu/). GENIALG was funded by the European Union Horizon2020 programme. The remit of the work was assessing the environmental footprint and ecosystem services provided by seaweed aquaculture in Europe to provide best practice advice to industry.

Gironde estuary environmental parameters and SPM maps generated from 41 Landsat-8/OLI and Sentinel-2/MSI images acquired over the period 2013-2018. Except bathymetry and daily river discharge data, that are accessible on public platforms, the dataset includes all of the time seris used in the publication: Analysis of suspended sediment variability in a large highly-turbid estuary using a 5-year-long remotely-sensed data archive at high resolution, Journal of Geophysical Research: Oceans, (DOI:10.1029/2019JC015417)-[https://doi.org/10.1029/2019JC015417]. Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.

The main part of the dataset has been collected within the MOMO project (Monitoring and modelling of cohesive sediment transport and evaluation of the effects of dredging and dumping operations on the marine ecosystem) at four locations (MOW1, Blankenberge, WZ-buoy, MOW0, Ostend and Geul van de Walvisstaart buoy). A large part of the data is from the MOW1 station, situated about 3 km offshore the harbour of Zeebrugge. Shorter time series have been collected for the Environmental Impact Assessment of the Belwind offshore windfarm at two locations (Blighbank, Gootebank) and the MOZ4 project (Westdiep location). A central objective of the MOMO project is to collect long-term time series of Suspended Particulate Matter concentration, size and transport in the coastal turbidity maximum located in the Belgian Part of the North Sea. Data from two sensors are included in this dataset. First, from a LISST-100X instrument, which contains four parameters: the optical transmission, the median distribution of the sediment particle size (micrometers), the Sauter mean diameter (micrometer) and the total SPM volume concentration (microlitres/litre). Second from in-situ observation of water turbidity derived from an Optical Backscatter Sensor (OBS) together with a CTD sensor. The following parameters are included: water pressure, salinity, water temperature, turbidity and SPM mass concentration (mg/l). The OBS is calibrated in the laboratory using standard turbidity solutions, and in the field using SPMC determined through filtration of water samples. -Observations of 3-D flow velocity field measured with an Acoustic Doppler Velocimeter (ADV). -In-situ observations of particle size distribution and sediment concentration measured by a Workhorse LISST-100X instrument. Four parameters are measured by the sensor: the optical transmission, the median distribution of the sediment particle size (micrometers), the sauter mean diameter (micrometer) and the total sediment volume (microlitres/litre). -Current profiles measured with an Acoustic Doppler Profiler (ADP) sensor -3-D flow velocity field measured with an Acoustic Doppler Velocimeter (ADV)
