Spectacular blooms of Phaeocystis antarctica in the Ross Sea produce some of the world's highest concentrations of dimethylsulfoniopropionate (DMSP) and dimethylsulfide (DMS). This dataset contains physiological and biochemical measurements from a research project investigating DMSP lyases, the effects of radiation and darkness on compound dynamics, and intracellular methanesulfonic acid (MSA). The data was contributed by AMD_USAPDC and last updated in May 2014.
Use Cases
- Model DMS flux to the atmosphere using measurements of DMSP and DMS concentrations from Ross Sea blooms.
- Analyze the relationship between photosynthetically active radiation, ultraviolet radiation, and intracellular DMSP levels.
- Study survival mechanisms by examining changes in DMSP and related compounds during prolonged darkness experiments.
- Investigate radical scavenging functions by detecting intracellular methanesulfonic acid (MSA) measurements.
- Characterize DMSP lyase enzymes using amino acid and gene sequence information from Phaeocystis antarctica.
Strengths
- Focus on a key species in a region with the world's highest concentrations of DMSP and DMS.
- Research design includes controlled experiments on radiation, darkness, and enzyme characterization.
Limitations
- Dataset size, row count, and specific column details are unknown.
- Data is from 2014 or earlier, which may limit relevance for contemporary climate modeling.
- Geographic scope is limited to the Ross Sea, Antarctica.
