Dynamics of carbon export from Maine watersheds to the Gulf of MaineSSP

Coastal ecosystems are highly influenced by the presence of organic matter in the form of carbon, nitrogen, and phosphorus. Dissolved and particulate organic carbon (DOC/POC respectively) are produced in terrestrial ecosystems and transported to the coast by rivers and streams through runoff processes. Carbon mobilization and transport is expected to change drastically in the near future due to changes in land use, temperature, and precipitation. The changing flux of carbon to the coast will alter the biogeochemistry of coastal ecosystems and affect many respects of their functionality, including the severity and frequency of harmful algal blooms and the productivity of local fisheries. To better understand how the changing flux of carbon will alter coastal ecosystems in Maine, we must first investigate the processes that factor into carbon mobilization and transport. I’m looking at how carbon export from tributaries draining watersheds  changes with different land use types and across three major river systems in Maine (Androscoggin/Kennebec, Penobscot, and St. John), how the seasonal dynamics of carbon export change from spring thaw to summer, how direct measurements of DOC/POC correlate with optical proxies, estimating the flux of carbon to the coastal waters of the Gulf of Maine and the Bay of Fundy, and how do these values compare to what is known from satellite-based estimates of carbon delivery to the coastal ocean.

Pecha Kucha

These presentations are in PechaKucha format. PechaKucha is Japanese for ‘chit-chat’. It is a presentation methodology devised in 2003 in which 20 slides are shown for 20 seconds each. The slides auto advance to keep the presentations concise and quick paced. Each presentation is (about) 6 minutes and 40 seconds long.
