Full description

This data set was collected from a ocean acidification minicosm experiment performed at Davis Station, Antarctica during the 2014/15 summer season. It includes:
- description of methods for all data collection and analyses.
- environmental data logged throughout the experiment; nutrients, temperature, light climate.
- carbonate chemistry data; pH (on Total scale), fugacity of CO2, dissolved inorganic carbon concentration, practical alkalinity, Omega calculations for both araganite and calcite.
- product datasheet (including transmission spectra) of Osram 150W HQI-TS/NDL metal halide lamps.

Context from the public summary for project 4026:
Manmade CO2 has increased ocean acidity by 30% and it is projected to rise 300% by 2100. Antarctic waters will be amongst the earliest and most severely affected by this increase. Microbes are the base of the marine food chain and primary drivers of the biological pump. This project will incubate natural communities of Antarctic marine microbes in minicosms at a range of CO2 concentrations to quantify changes in their structure and function, the physiological responses that drive these changes, and provide input to models that predict effects on biogeochemical cycles and Antarctic food webs.

Lineage

Progress Code: completed
Statement: The minicosm experimental design measured the microbial community growth in six unreplicated fCO2 treatments. Therefore, sub-samples from each minicosm were within-treatment pseudoreplicates and thus, results of statistical analysis must be interpreted conservatively.

Notes

Purpose
This data set contains all environmental and carbonate chemistry data that was logged during the Davis 14/15 ocean acidification minicosm experiment.

Data time period: 2014-11-19 to 2014-12-08
