AI Article Synopsis
- The marmap package allows users to download, plot, and manipulate bathymetric and topographic data in R, facilitating easy access to the ETOPO1 database from NOAA.
- It features interactive functions for querying data directly from generated maps and can handle simple data formats like ASCII for latitude, longitude, and depth.
- The package supports advanced plotting for creating detailed maps and can analyze surface areas and path distances, making it useful in fields like molecular ecology to study genetic isolation by distance.
Article Abstract
In this communication we introduce marmap, a package designed for downloading, plotting and manipulating bathymetric and topographic data in R. marmap can query the ETOPO1 bathymetry and topography database hosted by the NOAA, use simple latitude-longitude-depth data in ascii format, and take advantage of the advanced plotting tools available in R to build publication-quality bathymetric maps. Functions to query data (bathymetry, sampling information…) are available interactively by clicking on marmap maps. Bathymetric and topographic data can also be used to calculate projected surface areas within specified depth/altitude intervals, and constrain the calculation of realistic shortest path distances. Such information can be used in molecular ecology, for example, to evaluate genetic isolation by distance in a spatially-explicit framework.
