This dataset comprises the delta-13C and delta-15N stable isotopic information from two tissue samples (whole blood and mantle feathers) from 16 adults of 8 species of Southern Ocean procellariform collected at Bird Island, South Georgia during the austral summer 2001-2002. There have been numerous long-term research projects carried out at Bird Island under the auspices of the British Antarctic Survey, and this data represents one very small component that has been used to examine inter-specific competition in both the breeding and non-breeding periods.

The dataset contains three modelled estimates of global ammonia emissions from seabird colonies, at a spatial resolution of 0.1 degrees latitude/longitude. The model estimates were derived with a) detailed global seabird population data collated from a large number of sources (data sources date from 1980-2010 for different parts of the world) b) climate data (source: High-resolution Gridded Datasets, Climatic Research Unit, University of East Anglia, UK. http://www.cru.uea.ac.uk/cru/data/hrg/ last updated by Harris, I. (2007), date: 1995) c) emission model derived by Riddick et al. (2012) with funding for the project from the CEH Integrating Fund (NERC). A detailed description and discussion of the datasets, including methodology and uncertainties, can be found in the following peer-reviewed article: S. N. Riddick, U. Dragosits, T. D. Blackall, F. Daunt, S. Wanless and M. A. Sutton (2012) The global distribution of ammonia emissions from seabird colonies.

This dataset contains prey items of common guillemot Uria aalge and razorbill Alca torda observed during the 2017 breeding season at East Caithness Special Protection Area, Buchan Ness to Collieston Coast Special Protection Area and Isle of May National Nature Reserve, off the east coast of Scotland.
