Functions to work with seabird tracking data, in particular to identify marine IBAs based on Lascelles et al (2016). These functions were originally developed by Phil Taylor and Mark Miller, but had to be updated to streamline code, improve computational efficiency, and overcome obsolete or redundant functions that are no longer supported in newer R versions (>2.5.0). Note that these functions have been superseeded by the new 'track2KBA' package which is available Here: https://cran.r-project.org/web/packages/track2KBA/index.html
This package is also described in detail in this paper: https://besjournals.onlinelibrary.wiley.com/doi/10.1111/2041-210X.13713
Other functions relate to the spatial scales at which seabirds forage and have been published in: https://www.sciencedirect.com/science/article/pii/S0308597X18302422
