Sarah Jayne (Northeastern co-op student) and Kelsey Gosselin (research assistant), both of whom work in Amanda Spivak's lab in Marine Chemistry and Geochemistry. Sarah has the red hair. They are sectioning sediment cores that were collected from several different lakes in the Kennebec river watershed in Maine, with the goal of understanding how damming affects the biological and chemical structure of the lake ecosystems.
Image Of the Day caption:
Sarah Jayne, a guest student from Northeastern University working in the lab of WHOI biochemist Amanda Spivak, breaks down a piece of core sampled from the Kennebec river watershed in Maine. Removal of dams from some parts of the river recently resulted in the restoration of river herring populations. Herring have an important role in the food web, but have previously been unable to migrate to freshwater due to human activities like damming. Spivak is collaborating with biologist Joel Llopiz on an interdisciplinary project to determine the impact of dam removal on biological, geological, and chemical cycling in these environments.
