Susquehanna Shale Hills Critical Zone Observatory Stream water and Porewater Chemistry (2006-2010)

An intense field study was conducted at the Susquehanna/Shale Hills Critical Zone Observatory to use water chemistry to probe the subsurface hydrogeochemical conditions and water flow dynamics. Soil pore water sampled through tension lysimeters suggest that contemporary reaction rates depend on preferential flowpaths and solute residence times, and are limited by dissolution kinetics. Thus...

IEDA: EarthChem Homepage

Welcome to the EarthChem website.

The new EarthChem web site gives you access to all data systems and services for geochemistry that are operated by the Integrated Earth Data Applications (IEDA) Research Group, including the EarthChem Library, PetDB, NAVDAT, and SedDB.

EarthChem develops and operates digital data collections that support the preservation, discovery, access and analysis of geochemical data, and facilitates their integration with the broad array of other available earth science parameters. EarthChem uses advanced information technologies and data management practices in order to advance science and education.

EarthChem data collections are developed, operated and maintained by a joint team of disciplinary scientists, data scientists, data managers and information technology developers at the Lamont-Doherty Earth Observatory as part of the Integrated Earth Data Applications (IEDA) Research Group. IEDA is a collaborative effort of the EarthChem Program and the Marine Geoscience Data System (MGDS) to develop and operate integrated data services for the Earth and Ocean Sciences.
