Seahorse species predicted habitat distributions and associated environmental data layers covering the shelf seas surrounding the UK

This dataset contains predicted seahorse habitat distributions for two species 
(*Hippocampus hippocampus *and *H. guttulatus*) and the genus combined 
(Hippocampus hippocampus MAXENT.asc, Hippocampus guttulatus MAXENT.asc and 
Hippocampus sp. MAXENT.asc, respectively). Rasters of the raw predicted 
habitat suitability outputs from the maximum entropy (MAXENT, Phillips et al. 
2006) species distribution model algorithm are provided.

Additionally, the environmental data layers used for modelling the species 
distributions, including distance to seagrass habitat (degrees) (Distance From 
Seagrass.tif), distance to the coastline (DistCo.tif) bathymetry (m) 
(Bathy.tif), minimum winter and maximum summer SST (oC) (Kriging SST Winter 
Min.tif and Kriging SST Summer Max.tif, respectively) and chlorophyll a 
concentration (mg m-3) (Kriging Chla Winter Smooth.tif and Kriging Chla 
Summer Smooth.tif, respectively).

All raster layers are provided in the WGS84 (EPSG::4326) spatial reference 
system. All raster layers are at a gridded resolution of 0.0042 x 0.0042 
degrees. All layers cover the shelf seas surrounding the UK, including the 
English Channel, Celtic Seas, North Sea, and extend into shallow coastal and 
estuarine habitats. Raster layers of predicted habitat suitability are 
provided in ASCI format, whilst environmental predictor layers are provided in 
TIFF format.

This work was prioritised by Natural England’s Seahorse Working Group and was 
funded by Natural England. This work was conducted in collaboration with The 
Seahorse Trust who provided the seahorse occurrence data. The information 
provided will support marine spatial planning to reduce the broader impact of 
anthropogenic activities and enable better decision-making to protect these 
sensitive species and their habitats.

1989 University of Southampton, Poole Bay, Benthic hand-core and dive survey

All these records relate to "Jensen, Mallinson, Ovenden, Sheader (1989) Poole Bay Grid Baseline Benthic Survey 1988" A copy of the report is held at English Nature (Dorset Team).
     In response to environmental concerns relating to drilling and possible future oil extraction activities in Poole Bay, a baseline survey of the benthic infauna and epifauna was undertaken during June and July 1988. A benthic survey grid of 35 stations was sampled in western Poole Bay. At each site eight 0.006m2 hand cores were collected, one for chemical and sediment analysis and seven replicates for biological analysis. In addition to infaunal studies, the seabed and its associated surface flora and fauna were surveyed to compile a species list for the entire survey area. The sediment analysis revealed that the area was essentially sedimentary with a few outcrops of hard substrate, both natural and anthropogenic. Bottom sediments varied from sand with cobbles to a sandy mud. The infauna was dominated by polychaetes. The dominant epifaunal component was Crepidula fornicata (slipper limpet) beds. A maerl bed was recorded around station G3. Each station was located with AP DYN IV DECCA equipment. A local correction factor was used to reduce the position error to a theoretical 25-50m. Photographs and specimens were taken. The original photographs are held by Department of Oceanography, Southampton University, with a set of copies available from Wytch Farm. In addition to the sediment coring, loose particulate material was tested to detect levels of heavy metals - NB sediment details are not held on this database. Of the 35 stations visited 7 had sediment too compact to allow a sufficient number of replicates for biological analysis. These stations were: B2, C2, D1, E1, E6, E7 and G3.

Selectivity of hake gill nets in the Southwest fishery 2005/06 - Fisheries Science Partnership

To examine the catch composition and selectivity of a range of static gears 
for hake in the southwest fisheries.

FSP Programme 8 demonstrated the selectivity characteristics of 120mm mesh 
gill nets used by UK hake fishermen off the south west coast of England. The 
experiment was carried out by comparing the catches in nets of mesh size 80, 
100, 120 and 140mm deployed simultaneously at two fishing grounds. Additional 
120mm nets were shot to obtain further data on size composition of hake. The 
work was carried out in October and November 2005, using the vessel *Carol

Videos and still images of the seabed from the 2017 survey of Grenada and the Grenadines Islands in the Caribbean

As part of the Commonwealth Marine Economies Programme (CMEP) Cefas collected 
87 drop camera video tows of the seabed on the southern and western sides of 
the island of Grenada and around the Carriacou and the Grenadines Islands. 
These videos of the seabed were to characterise the benthic fauna within the 
area and support the creation of benthic habitat maps from UKHO lidar data. 
The videos and still images were acquired during the 2017 survey using a 
lightweight drop camera frame with two GoPros simultaneously collecting stills 
and video data. Two lasers were fitted for scaling images and additional 
lighting provided real colour images of the seabed. The drop camera frame was 
lowered to the seabed by hand from a vessel, with the video monitored to 
maintain a consistent height above the seabed. Tows were 15 minutes long with 
the vessel drifting in neutral so the distance covered in each tow varied. 
Sample depths ranged from 3-40 m and covered a range of habitats including 
bare sediment, seagrass, and coral and sponge dominated reefs. Still images 
were acquired every minute at a point when the seabed was clearly in focus.

Demersal stereo-Baited Remote Underwater Videos collected around the north west coast of St. Lucia in 2019

As part of the Commonwealth Marine Economies Programme (CMEP) Cefas conducted 
a demersal stereo-Baited Remote Underwater Video (BRUV) survey of the western 
side of the island from Soufriere Bay to the northern tip of St. Lucia. A 
total of 87 1-hour long samples were successfully acquired to a maximum depth 
of ~50 m during a two week survey in February 2019. Four camera frames were 
used, each fitted with two Sony FDR-X3000 ActionCam cameras with a 7-degree 
inward facing angle directed at the wire mesh bait bag. Stereo-BRUVs field of 
views were calibrated using the SeaGIS calibration cube and the CAL software. 
Calibration videos were acquired at the start and end of the survey. At each 
station light and temperature were also recorded using a HOBO logger and these 
raw files are also provided in the raw format and as .csv file.

The data in this archive were collected from CEFAS (Or DFR) research cruises. 
They broadly cover the European Shelf with some data from the Iberian Abysal 
Plain. Data were collected using the lowered CTD rosette system which is used 
when the vessel is stationary. Usually bottles were fired at particular depths 
and samples taken for calibration. In early years only a limited set of 
parameters were collected. Notably Pressure (Depth), Temperature and 
Conductivity (CTD). From Conductivity Salinity can be calculated using the 
UNESCO 1978,1983 formulations . In subsequent years more sensors have been 
added, notably fluorometers, Optical back scatter or transmissometers and 
Light (PAR, photo synthetically available radiation). The exact configuration 
varies between cruises and this is reflected in the data format of the output 
files.

Data was collected from research vessels on station, a profile from the 
surface to near the sea bed is undertaken. The down cast data should be a 
clean profile. Water bottles for sample collection and calibration are fired 
on the up cast.
