Tools for modelling species distributions using marine mammal data from Seaquest Southwest recording scheme

Code supplied here can be used to analyse data collected by the Seaquest Southwest monitoring scheme organised by the Cornwall Wildlife Trust. The data is not included in the package but can be requested https://erccis.org.uk/requesting-data and the code here can be used to model encounter rates for Common Dolphin, Grey Seal, and Harbour Porpoise using a variety of methods, including calibrated Random Forest models. Data may also be adequate for modelling encounter rates for Bottlenose Dolphin and Basking Shark, although further investigation is required. The package contains all the code necessary to process the species and environmental data, run models and plot results.
