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.

This dataset contains dissolved iron concentrations ((Fe(II) + Fe(III); µmol/l) acquired between July 2014 and August 2014 (n=332) using the CHEMINI Fe, a CHEmical MINIaturized analyser (samples taken every 24 hours, with daily in situ calibration using a 25 µmol/l iron standard, Vuillemin et al., 2009). The sample inlet was positioned on the mussel bed at the base of the Tour Eiffel edifice of the Lucky Strike hydrothermal vent (1695 depth).CHEMINI Fe (CF1) was mounted on the TEMPO module which was itself connected to the SeaMON East node of the EMSO-Azores observatory.

The Galway Bay Subsea observatory was installed in 2015 on the seafloor in the Galway Bay Marine and Renewable Energy Test Site, which is an area 1.5km off Spiddal pier and is used primarily to test small-scale ocean energy devices. The observatory uses cameras, probes and sensors to permit continuous and remote live underwater monitoring. This observatory equipment will allow ocean energy developers to monitor how their devices are performing in the ocean as well as give ocean researchers unique real-time access to monitor ongoing changes in the marine environment. Data relating to the marine environment at the site are now being transferred in real-time from the Galway Bay Observatory to the Marine Institute headquarters and onwards onto the internet. This data set includes estimates of the chlorophyll and turbidity levels in the water which give an indication of the volume of phytoplankton and other particles, such as sediment, in the water. The data platform for the Galway Bay Observatory has been built using Big Data technology, so that when new instruments are plugged into the cable system it is straightforward to include the new data streams into the system. The real-time underwater video footage and all the data from the various sensors and instruments is continuously refreshed and displayed online. The web-viewer can be accessed using the Google Chrome web browser at: http://smartbay.marine.ie. This submission contains 1 months daily files from February 2018. The full data are available from the weblink provided.

GEMS Survey Ltd. (GEMS) was awarded a contract by Channel Energy Limited to undertake metocean data collection in the Bristol Channel as part of the Atlantic Array wind farm development project. The scope of work includes the deployment of two acoustic wave and current (AWAC) units and one Directional Waverider Buoy. Ancillary work includes water and sediment sampling and water profiling. Following non-recovery of AWAC devices, TRIAXYS Directional Wave buoys were utilised for the rest of the survey. This series contains both reports and datasets associated with the Metocean Assessment.
