Dissolved Organic Carbon and Microbial Diversity in WAIS Divide Ice Cores

Molecular-level characterization of dissolved organic carbon and microbial communities from Antarctic ice cores. The dataset was created by researchers from AMD_USAPDC, with data last updated in April 2015. It serves as a pilot study to optimize protocols for DNA extraction and carbon analysis from deep ice.

Use Cases

• Analyze microbial diversity data from ice core DNA to study ancient microbial communities and their survival.
• Correlate molecular characterizations of dissolved organic carbon with microbial presence to understand carbon cycling in ice.
• Use protocol optimization results on DNA extraction and amplification yields to plan future ice coring projects.
• Investigate the relationship between microbial biomass estimates and carbon content measurements within the ice matrix.

Strengths

• Data generated using advanced techniques like next-generation pyrosequencing and FT-ICR-MS.
• Project designed as a foundational pilot to quantify material requirements for future large-scale studies.

Limitations

• Specific row counts, column names, and sample sizes are not provided.
• Data is from 2015 and may not reflect the most current analytical protocols.
• Geographic scope is limited to the WAIS Divide location in Antarctica.
