Data for analyses
Cleaned dataset used for all analyses. The included variables and main sources of the data are listed below. See the paper and supplemental information for more details.
- Year - year of stranding
- Species - latin binomial with taxonomy corrected to Reid et al 2003
Source - CSIP, IWDG or NHM. NA indicates there were no data for that species for that particular year. CSIP is the cetacean
- Total_strandings - Number of individuals stranded.
- Human_population - UK and Ireland yearly human population (millions of people). 1913-1922 are figures for England, Wales and Scotland; from 1922, onwards Northern Ireland is included. Office of National statistics (ONS).
- Storms - Storm events (count/year) over 50 knots. Source: Lamb and Frydendahl (1991), Met Office, UK.
- Max_K_index - Geomagnetic activity (K-index) . The K-index is used to characterise the magnitude of geomagnetic storms. The range is 0–9, with 1 being calm and 5 or more indicating a geomagnetic storm. Three-hourly readings obtained from: 1913 - 1925: Greenwich; 1926 - 1939: Abinger; 1940 - 1956: Abinger, Eskdalemuir and Lerwick; 1957 - 2015: Hartland, Eskdalemuir and Lerwick. A mean maximum yearly K-index reading was used in the model. Source: British Geological Survey.
- Max_SST - Maximum yearly sea surface temperature (°C) from 14 UK and Irish locations. A mean maximum yearly reading was used in the model. Source: Met Office: HadISST.
- NAO_index - North Atlantic Oscillation (mb). Yearly readings. The NAO is based on the difference of normalised sea level pressure (SLP) between Stykkisholmur/Reykjavik, Iceland, and Lisbon, Portugal. Source: University Corporation for Atmospheric Research.
- Fish_catch - UK and Irish fishing catch data (1000 tonnes per year). Yearly fishing catch data from the International Council for the Exploration of the Sea (ICES). The dataset was compiled from 3 separate ICES datasets which contain data on catches of ~58 species; ICES Historical Landings: 1903 – 1949; Historical Nominal Catches: 1950 – 2010; Official Nominal Catches: 2006 – 2016
