Environment & earth sciencefree
Archive of US geologic maps, reports, and stratigraphic names. Many older survey publications are scanned PDFs that upload straight into a notebook.
This archive holds decades of US geologic maps and survey reports, many of them scanned older publications that upload as PDFs without extra conversion. It fits a notebook researching the geology of a specific US region, especially where the mapping history itself matters. Scan quality and readability vary a lot depending on how old the original document is.
Import into Gemini Notebook
- 1Copy the link above (or a specific page from the site).
- 2In your notebook, click Add source → Website.
- 3Paste the link and confirm — several links can be pasted at once, one per line.
Raw climate and geodata rarely imports directly — bring in the documentation, technical reports and summary pages instead of the datasets themselves.

- Copernicus Climate Data StoreEU climate reanalysis and projection datasets such as ERA5. Raw data needs processing first; the dataset documentation pages import as sources.
- CORINE Land CoverEuropean land-cover maps in 44 classes, tracked since 1990. The GIS data itself won't import; use the product documentation and technical reports.
- EarthChem Data ServicesOpen geochemistry, geochronology and petrology datasets from the earth science community. Good grounding for rock and sediment chemistry questions.
- EMODnet Digital BathymetrySeafloor depth model for Europe's sea basins built from thousands of surveys. The documentation pages work as sources for marine mapping projects.
- FAOSTATUN statistics on crops, livestock, land use and food security for 245 countries, with free downloads back to 1961. Strong grounding for agriculture research.
- GBIFOpen records of where species have been observed worldwide — hundreds of millions of occurrences. Species and dataset pages cite the original surveys.
- GEBCO – General Bathymetric Chart of the OceansThe standard global ocean depth grid, free to download. Its documentation and cookbook pages ground questions about seafloor mapping.
- Global Human Settlement LayerEU JRC grids tracking built-up land and population worldwide across decades. The technical report PDFs import cleanly and explain each layer's methodology.
- International Energy Agency DataEnergy production, consumption, and emissions statistics by country. Free report PDFs and data explorers; full datasets require a license.
- International Ocean Discovery Program (IODP) DataCore samples, borehole logs, and site data from decades of scientific ocean drilling. Expedition reports are open-access and import well as PDFs.
