Supplementary GIS data for: Recent geospatial dynamics of Terceira (Azores, Portugal) and the theoretic implications for the biogeography of active volcanic islands (Rijksdijk et al. 2020)

GIS data files with metadata used to calculate the changes in surface area over a 120 ka period in 10 ka time bins on the volcanically active island of Terceira (Azores). We took into account changes in sea level and subsidence during the analyses, and we did all analyses in ESRI ArcGIS 10.2.2 desktop software in WGS_1984_UTM_Zone_26N Transverse Mercator projection which resulted in minimal area distortions (<1%) for the scale of our analysis (1-100 km2). Dataset is a file geodatabase with: - Thirteen polygon shapefiles of contours reconstructed for Terceira in time bins of 10 ka for 120 ka until present. The name of volcanic origin (Cinco Picos Volcano, Guillerme Moniz Volcano, Pico Alto Volcano, Santa Barbara Volcano, Basaltic Fissural Area), the age of the event, area and shape of each polygon are included in the attribute tables. - Three polygon shapefiles of contours for 141, 270 and 370 ka used for analyses. - European Marine Observation and Data Network (EMODNet) bathymetry raster dataset downloaded from EMODnet Bathymetry portal (http://www.emodnet-bathymetry.eu) and clipped to study area and immediate surroundings
