Methodology

Methods:

The dissolved gas and tritium samples were analyzed at the Rare Gas Lab at the University of Rochester, Rochester, NY

The stable isotope samples were analyzed at INSTAAR, University of Colorado at Boulder .

The major ions were analyzed at the MCM-LTER Laboratory at Crary Laboratory in McMurdo Station, Antarctica.

Maintenance:

This dataset was created March 27, 2009 by MCM-LTER information manager (Chris Gardner, Sue Welch) after email discussion with coPI Carolyn Dowling.

On 2014, the metadata was enhanced for usability with help of the Drupal Ecological Information Management System (Inigo San Gil)

in 2016, metadata was refined
