Borehole Optical Stratigraphy measurements track temporal and spatial variations in firn compaction at Summit, Greenland. Data collection occurred over two winter and three summer seasons between 2004 and 2008, led by Principal Investigators from the University of Washington and the Desert Research Institute. The dataset informs on accumulation rates from 1980 to 2008.
Use Cases
- Modeling the seasonal cycle of firn densification rates using tracked borehole wall details and temperature data.
- Calculating gas-age/ice-age offsets for paleoclimate records by analyzing firn compaction and pore close-off depth.
- Interpreting remote-sensing mass-balance studies by correlating surface height changes with measured densification and accumulation rates.
- Advancing snow morphology models through in-situ measurements of firn compaction strain and vertical motion.
Strengths
- Measurements span two winter and three summer seasons, capturing seasonal variation.
- Data informs on accumulation rates covering a 28-year period from 1980 to 2008.
Limitations
- Specific row count, column names, and sample size are unknown.
- Data collection ended in 2008, limiting analysis of recent ice sheet dynamics.
- Geographic coverage is limited to a single site at Summit, Greenland.
