Antarctic Sea Ice Microbial Community and Environmental Sensor Data

Microbial community data and environmental sensor readings from Antarctic sea ice ecosystems. Data was collected by the SCIOPS organization during field research at Cape Evans, Turtle Rock, and other sites in the 2010-2011 and 2011-2012 seasons. Measurements include CTD casts for temperature, conductivity, salinity, depth, and chlorophyll, alongside PAR, UVB irradiance, and air temperature recordings.

Use Cases

• Analyze correlations between sea ice microbial community fingerprints and concurrent CTD measurements like temperature, salinity, and live chlorophyll.
• Model the relationship between environmental drivers such as PAR, UVB irradiance, and air temperature recorded at solar noon and microbial abundance data.
• Use high-frequency HOBO logger data recorded at 10-minute intervals to study fine-scale temporal changes in ice temperature profiles.
• Compare spatial variations in microbial biodiversity and community structure between field sites like Cape Evans and Turtle Rock using the generated bio-inventory.

Strengths

• Data collection spans two consecutive Antarctic research seasons (2010-2011, 2011-2012).
• Includes high-temporal-resolution ice temperature data from HOBO loggers recording at 10-minute intervals.
• Integrates traditional microbial analysis with modern molecular techniques like DNA fingerprinting and high-throughput sequencing.

Limitations

• Specific row counts, column names, and dataset size are unknown.
• Temporal coverage is limited to two summer seasons over two years.
• Geographic coverage is restricted to specific Antarctic sites (Cape Evans, Turtle Rock).
