OBIS-USA brings together marine biological observation data – recorded observations of identifiable marine species at a known time and place, collected primarily from U.S. waters or with U.S. funding.

The European Soil Data Centre (ESDAC) is the thematic centre for soil related data in Europe. Its ambition is to be the single reference point for and to host all relevant soil data and information at European level. It contains a number of resources that are organized and presented in various ways: datasets, services/applications, maps, documents, events, projects and external links.

National Atlas ended in 2014, but the new home of the component parts of the project, with links, is located here.

A dataset of the world's volcanoes. "The mission of GVP is to document, understand, and disseminate information about global volcanic activity. We do this through four core functions: reporting, archiving, research, and outreach. The data systems that lie at our core have been in development since 1968 when GVP began documenting the eruptive histories of volcanoes."

"Paleoclimatology data are derived from natural sources such as tree rings, ice cores, corals, stalagmites, and ocean and lake sediments. These proxy climate data extend the weather and climate information archive by hundreds to millions of years. The data include geophysical or biological measurement time series and some reconstructed climate variables such as temperature and precipitation. Scientists use paleoclimatology data and information to understand natural climate variability and future climate change."
