Each year, sea ice forms and melts around Antarctica. Algae living inside the ice fuel food webs from the ocean surface down to the seafloor.

What they work on
- Measure how different sympagic algal species adapt their growth and cell properties to seasonal sea ice formation and melt, using a laboratory ice tank modeled on Antarctic Peninsula conditions.
- Compare primary production measured by carbon dioxide drawdown, oxygen production and variable fluorescence in sea ice versus seawater.
- Test how ice algae alter the physical structure of sea ice and how they contribute to organic matter cycling during ice melt.
More about the research
Sea ice is changing from year to year and with climate change, yet little is known about how ice and its algae affect each other. Climate models also represent sea-ice biology poorly.
Why it matters
Antarctic and Arctic food webs depend on algae in sea ice, but climate and Earth system models lack good data on them. Measurements of how these algae grow, shape ice and cycle carbon could help oceanographers and modelers predict how polar ecosystems and climate respond as sea ice changes.
Known grants
From NIH and NSF research grants. Labs often have other funding we can't see.
