The Interdisciplinary Earth Data Alliance (IEDA) data facility aims to, “support, sustain, and advance the geosciences by providing data services for observational geoscience data from the ocean, earth, and polar sciences.” The IEDA, which is funded by the US National Science Foundation, is headed by staff at Columbia University’s Lamont-Doherty Earth Observatory. On this website, you will find a number of data repositories and data syntheses, which are collections of data sets with a shared area of investigation. Data repositories include information in the fields of Antarctic science, marine geology and geophysics, and geochronology. You can also download the free GeoMapApp, which is a free software tool for creating data visualization. Check it out!
