Aquaculture - Inactive and deregistered sites (18.11.2024)	Point data identifying the location of finfish or shellfish farms around Scotland from the Fish Health Inspectorate Aquadat database. This includes fishery sites which are ponds or other installation where farmed fish are stocked for recreational fishing (either private or commercial). The data includes the three categories: Active: is the status of a site that is stocked or fallow with the intention of restocking in the foreseeable future. Inactive: is the status of a site that is unlikely to be stocked in the foreseeable future. Deregistered: is the status applied to a site that is no longer used for the purpose of fish or shellfish production; the lease has been surrendered.
ECOMMAS Proportion Porpoise 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. Acoustic recorders (C-PODs and SM2Ms) are deployed at 30 sites across 10 locations along the east coast. They record underwater noise and count echolocation clicks to measure dolphin and porpoise presence and absence. They are deployed in the spring and are recovered after ~ 4 months. In 2015 and 2016, a second deployment was issued in July/August. Data is presented as detection-positive days (DPD) and detection-positive hours (DPH) for both species. DPD = The detection of echolocation clicks per day (1 = Detection-positive, 0 = Detection-negative) 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 nephrop 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.
Offshore Wind 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 wind energy sites.
