The dataset comprises counts of ten waterfowl species collected from Loch Leven from 1968-2007 by staff at Scottish Natural Heritage (SNH) and its predecessor bodies (Nature Conservancy), as part of their long-term monitoring programme of the lake. Counts are for the whole loch and represent an annual peak count based on the monthly counts recorded from September (of the year indicated) through to March (of the following year).

This marine multibeam survey took place in August 2011 in the area around Noss Head and the Southern Trench in the Moray Firth on board the Northern Lighthouse Board vessel NLV Pole Star. The survey was carried out by the British Geological Survey (BGS) on behalf of Marine Scotland and Scottish Natural Heritage (SNH) for Marine Protected Area (MPAs) related studies. Sea floor bathymetry data were collected using a Kongsberg EM3002D multibeam system. These data are archived by BGS. Technical details of the survey are contained in the Report of Survey.

This marine multibeam and sidescan survey (2015_9_SNH) took place in three phases (25/11/2015 to 03/12/2015, 17-28/02/2016 and 04-17/04/2016) in the area off South and East coast of Arran on board the RV White Ribbon. The survey was carried out by the British Geological Survey (BGS) on behalf of Scottish Natural Heritage/MarineScotland. The aim of the survey was ensonification of 10 areas designated by SNH. Sea floor bathymetry data were collected using a Kongsberg EM3002D multibeam system and dual frequency Sidescan Sonar (100khz, 455khz). These data are archived by BGS. Technical details of the survey are contained in the BGS Report of Survey.

This marine multibeam survey took place in July 2011 in the area around the Isle of Canna on the west coast of Scotland on board the Northern Lighthouse Board vessel NLV Pole Star. The survey was carried out by the British Geological Survey (BGS) on behalf of Marine Scotland and Scottish Natural Heritage (SNH). Sea floor bathymetry data were collected using a Kongsberg EM3002D multibeam system. These data are archived by BGS. Technical details of the survey are contained in the BGS Report of Survey (OR/11/045), http://nora.nerc.ac.uk/id/eprint/516268/

This marine multibeam survey took place in March 2013 within the MPA (Marine Protected Area) proposal area of the Lochs Duich, Long and Alsh and the additional area of the Kyle of Rhea on board the RV White Ribbon. The survey was carried out by the British Geological Survey (BGS) on behalf of Scottish Natural Heritage (SNH). Sea floor bathymetry data were collected using a Kongsberg EM3002D multibeam system. These data are archived by BGS. Technical details of the survey are contained in the BGS Report of Survey CR/13/033.

This dataset contains concentrations of dissolved organic carbon, inorganic carbon, CO2, CH4 and N2O in the Black Burn stream which drains Auchencorth Moss peatland in South East Scotland. Concentrations and fluxes have been measured within the Black Burn on an approximately weekly to fortnightly basis from approximately 2006 to present (see https://doi.org/10.5285/3f0820a7-a8c8-4dd7-a058-8db79ba9c7fe). Concentrations in this dataset are from a series of new sites, upstream of the long-term sampling record, adjacent to an area of drains blocked by Scottish Natural Heritage. Measurements began during the drain blocking. Data was collected initially as part of a masters project for University of Edinburgh through Scotland's Rural College and continued by the Centre for Ecology & Hydrology.

[THIS DATASET HAS BEEN WITHDRAWN]. This dataset provides deposition values of sulphur and nitrogen deposition, deposition of non-marine base cations and concentration values for ammonia (NH3), sulphur dioxide (SO2) and nitrogen oxide (NOx) on the UK nature conservation protected sites, averaged over the years 2018 to 2020. The dataset also includes calculated minimum, maximum and gridded average values for each site. Protected nature sites covered are: (i) Special Areas of Conservation (SAC) (ii) Special Protection Areas (SPA) (iii) Sites of Special Scientific Interest (SSSI). The data consist of values of nitrogen and acid deposition, non-marine base cations deposition, and concentrations of ammonia (NH3) based on the Concentration Based Estimated Deposition (CBED), and concentrations of NOx and SO2 using the Pollution Climate Mapping (PCM) model. Nitrogen and acid deposition data is also given for specific habitat types including: (i) moorland/short vegetation everywhere, (ii) forest everywhere, and (iii) the grid square average over multiple land cover types (i.e. arable, grassland, forest, moorland, urban) These habitat-specific data are recommended for use with critical loads for the calculation of critical load exceedances using the relevant deposition/habitat type.
