pangaear is a data retrieval interface for the World Data Center PANGAEA (https://www.pangaea.de/). PANGAEA archieves published Earth & Environmental Science data under the following subjects: agriculture, atmosphere, biological classification, biosphere, chemistry, cryosphere, ecology, fisheries, geophysics, human dimensions, lakes & rives, land surface, lithosphere, oceans, and paleontology.

This package offers tools to interact with the PANGAEA Database, including functions for searching for data, fetching datasets by dataset ID, and working with the PANGAEA OAI-PMH service.

Search for data

This is a thin wrapper around the GUI search interface on the page https://www.pangaea.de/. Everything you can do there, you can do here.

pg_search(query = 'water', bbox = c(-124.2, 41.8, -116.8, 46.1), count = 3)
