Data for the glacier mass balance summaries was submitted by Andrew G. Fountain to the data manager in August, 1997. The column showing "file name" identifies the original file containing that record. These are provenance ascii text files and can be asked to the the McMurdo LTER data manager's office.
Once submitted, the data manager used Microsoft Excel and Access software to produce files that were in more of a relational mode.
In March, 2000, Thomas Nylen revised the existing data, and added new data from the more recent seasons. Instead of lumping all of the mass balance results for each glacier under one file, they were separated into files for each glacier. Results for Hughes and Suess glaciers were also added. Metadata fields were also completed at this time.
In April, 2000, Denise Steigerwald added fields for dataset code and glstkid. Dataset code would allow the data to be linked to the metadata in a relational database. Glstkid is a code that ties stake records to points on a GIS base map being developed by Michael Prentice at the University of New Hampshire.
Metadata was standardized in 2006 using the EML format and distributed throughout LTER and federal clearing houses (Chris Gardner, Inigo San Gil). in 2014, metadata was revamped using the Drupal Ecological Information Management system (Inigo San Gil)
