Endeavour segment ISS (Integrated Study Site) basalt geochemical analyses

Abstract: **This is a new version of a previously submitted dataset.** Excel spreadsheet of >300 major, trace, and isotope analyses of basalt lavas from the Endeavour segment of the Juan de Fuca Ridge. Most samples were collected by submersible and a location map on <1m resolution bathymetry is provided. Most samples are Holocene in age, and all analyses are normalized to common values. Basalts range in composition from highly depleted to highly enriched at short spatial and temporal scale.
