ECOMMAS Proportion Dolphin Detection-Positive Days (2013-2016 time aware content) |
ECOMMAS is a long-term, on-going study into how underwater noise generated by offshore industry impacts the distribution of dolphins and porpoises in the Scottish North Sea. Data is presented as detection-positive days (DPD) and detection-positive hours (DPH) for both species. DPD = The detection of echolocation clicks per day DPH = The number of hours echolocation clicks are detected per day Nall = Total number of clicks detected per day Ndays = Total number of days recorded PorpDPH_median = Median porpoise detection-positive hours for each site DolDPH_median = Median dolphin detection-positive hours for each site Proportion_PorpDPD = Proportion of porpoise detection-positive days (out of total days recorded, Ndays) Proportion_DolDPD = Proportion of dolphin detection-positive days (out of total days recorded, Ndays) Data has been prepared as ArcGIS maps showing median DPH and proportion of DPD for both species across all 30 sites. It has also been converted to be viewed on the NMPi, and for direct download as a spread sheet (.csv) |

ECOMMAS - Underwater noise levels in UK waters monitoring locations |
These data points are representative of the underwater noise recording locations referenced in the Underwater noise levels in UK waters report published in 2016. (Scientific Reports 6, article number 36942. DOI:10.1038/srep36942.) These points were created by Marine Scotland for use on Marine Scotland Maps. |

Creel Fishing Effort Study - Average number of crab and lobster hauls per day |
Measuring fishing effort is important for assessing the environmental sustainability of fish stocks and the socioeconomic efficiency of fishing activity. Fishing effort describes the amount of fishing gear used on a fishing ground over a given unit of time. Effort in this case is defined as number of creels hauled per day per 4 km2. This survey interviewed 198 creel vessel skippers from four regions, two on the west and two on the east coast of Scotland. This analysis has been produced from these SAMPLED vessels only. This IS NOT a census and IS NOT a map of all creeling effort in these waters or in the survey areas. This is an indication of potential fishing effort only and if creeling is not quantified in an area in this map, that DOES NOT mean creeling is not taking place. Equally quantified effort could be higher given some creeling vessels were not surveyed. Fishing effort outside of the surveyed area was not measured. |

Wave Lease Sites - Crown Estate Scotland |
‘Lease/Lease Agreement’ is a legal agreement from Crown Estate Scotland whereby an area of foreshore or seabed is occupied by a third party (a 'tenant') for an agreed purpose, such as renewable energy, and which gives consent for the tenant to develop on the lease site(s), if other required permissions are gained. This layer shows areas where there is a Crown Estate Scotland Lease/Lease Agreement in place for renewable wave energy sites. |

Rockall and Helen's Reef - high resolution multibeam echosounder bathymetry |
High resolution bathymetry data of Rockall and Helen's Reef collected 2011-2012 as part of the ROAME Offshore Fisheries and Conservation (OFFCON) project. Rockall, a tiny island just 19 metres high, sits on the very extremity of Scotland’s marine environment. Some 180 miles due west of St. Kilda, it is buffeted year round by the extreme winds and swell that the North Atlantic weather generates. As such, it is Scotland’s only truly offshore shallow water ecosystem. The islet of Rockall is actually the only part of vast plateau of submerged continent that remains above sea-level.
