A collation of datasets contributing to the MSFD baseline data for the current known distribution of non native species in the UK

Survey to establish the infaunal species composition and sediment properties of maerl bed habitats in Falmouth Harbour, from SCUBA diver collected core samples. Surveys were conducted in response to proposed dredging activities to deepen the shipping channel. Core samples collected by divers September - November 2012 and July - August 2013 were used to assess habitat quality and species distribution by quantifying the abundance of infauna and analysing organic content, particle size and maerl structure. There were 6 sites divided into three 5m2 plots. SCUBA divers collected 8 maerl core samples per plot: 5 cores for faunal analysis and 3 cores for sediment and organic content analysis.

Full community phytoplankton analysis results, expressed as cells per litre, from samples collected from the Gibraltar coastline between 2009 to 2019. The data were derived from water samples collected at a 2m depth using a Niskin sampler on an quarterly basis at four sites by HM Government of Gibraltar. Site positions are included in the dataset, and are accurate to +/- 30m.

Survey to establish the location and assess the extent, distribution and species composition of maerl bed habitats and quantify the abundance of associated epifauna communities in Falmouth Harbour, UK using a high definition towed underwater video system. Surveys were conducted in response to proposed dredging activities to deepen the shipping channel. The survey took place in November 2011 and transects were approximately 200 x 0.5 metres

A detailed distribution of true crabs (Brachyura) in the North-East Atlantic.

A collection of surveys completed in offshore UK waters by the Centre for Environment, Fisheries and Aquaculture Science (Cefas) to collect data on marine wildlife, habitats, geology and geomorphology of designated and recommended Marine Conservation Zones (MCZs).

Extract of the publicly available offshore UK marine benthic data holdings of JNCC (Joint Nature Conservation Committee), held within the “Marine Recorder” data management system. Data comprises multi-thematic benthic surveys in the offshore, including both taxa occurrence and abundance alongside physical and biotope recordings. This dataset is being used as a pilot study into submitting fully classified biotope data into OBIS alongside associated taxonomic occurrences under the EU EMODnet initiative.

Survey to establish the location and assess the extent, distribution and species composition of maerl bed habitats and quantify the abundance of associated epifauna communities in Falmouth Harbour, UK using a high definition towed underwater video system. Surveys were conducted in response to proposed dredging activities to deepen the shipping channel. The surveys took place in February 2012 and transects were approximately 200 x 0.5 metres.

This dataset consists of analysed phytoplankton data from the years 2001-2017 inclusive collected in UK waters from the SmartBuoy moorings at Celtic Deep, Dowsing, Gabbard/West Gabbard/WestGabbard2, Warp and Liverpool Bay using WMS and EDU automated water samplers. SmartBuoys consist of a 4 meter tall stainless steel frame with a fibreglass toroid for buoyancy. Instruments are attached at a nominal 1 meter depth to the frame. The water samplers collect into pre-spiked bags containing acidified Lugols Iodine on a pre-determined cycle over the course of a deployment. Following recovery these samples were analysed for a full community of phytoplankton species using the Utermohl method on high-power inverted microscopes. Phytoplankton cell counts are abundance values reported in Cells per Litre.
