Our lab group uses autonomous instrumentation to study ecological responses of marine communities in extreme environments to changes in climate and carbon cycling. The lab conducts an ongoing time-series study at Station M, 4,000 meters deep in the Northeast Pacific.

Station M instrumentation suite.

In addition to this work, studies in Antarctica measure impacts of melting icebergs on marine biogeochemistry (see published research). Our work in the Sargasso Sea has shown a major decline in biodiversity over the past 40 years, during which ocean temperatures and acidity have risen steadily.
