Climate change in extreme environments

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, 4000 meters deep in the Northeast Pacific.  In addition to this work, studies in Antarctica measure impacts of melting icebergs on marine biogeochemistry (see published research).  Our recent 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.
