  • What is "Blue Carbon"?

    | December 4, 2014 | Filed under: Opinion

    It sounds cool: Blue carbon. Have you heard of it? What does it make you think?

  • For Peat's Sake

    | October 25, 2014 | Filed under: Opinion

    Three hundred and fifty million years ago, the supercontinent Pangaea floated where you sit today. It was a warm, wet world, bathed in oxygen and soupy seas. The Carboniferous period was a time from which we get a lot of the fossil fuels we now use to power our society.

  • How to Catch 5,000 Green Crabs

    Wells Reserve Contributor | September 11, 2014

    Measuring a green crabThe invasive European green crab is not only a popular topic in the media these days; here at the reserve green crabs are receiving their fair share of attention as well — 5,878 of them so far to be exact!

    The Wells Reserve has teamed up with the University of Maine, Casco Bay Estuary Partnership, and Southern Maine Health Care to study the impacts of the invasive European green crab (Carcinus maenas) on the geology and “stability” of our marshes. Over the summer we have been collecting abundance data that will later be used in conjunction with fyke net data, water quality data, and even geological techniques to better understand the effects green crabs are having on salt marshes throughout southern Maine.

    Create a U.S./Canada working group, identify research gaps, and establish a regional approach to blue carbon science and policy.

  • Science: Building Upon the Work of Others

    | September 5, 2012

    Dr. Jennifer Dijkstra measures a snail with calipers.Jennifer Dijkstra was always going to be a scientist. As a child summering on Grand Manan, she clambered over the island’s rocky shoreline grabbing fistfuls of seaweed and peering into shallow waters to spy on crabs and snails. This summer she’s been doing the same thing, but with three degrees of separation (BS, MS, and PhD), she now calls her objects of interest Ascophyllum, Carcinus, and Littorina.

    For many budding biologists, the journey from tide pool playground to salt marsh research transect stops short. For Dr. Dijkstra, research scientist at the Wells Reserve, the dream came true.

  • Sea level rise redux: Using what we know

    Wells Reserve Contributor | July 1, 2002

    It is probably a rare coastal beachfront property owner who is not aware that beaches are dynamic systems that erode and accrete in response to storms, sediment supply, rising sea level, and the proximity of sea walls, jetties, and other forms of coastal "armor." Many beachfront owners are also aware that "natural" barrier beaches and their dune systems are able to persist in the face of sea level rise by transgressing, or migrating shoreward.
