Portland, Maine:: Rebecca Goodale,, 2014.. Edition of 3. 18.5 x 20.5"; 11 leaves. Drypoints on Japanese paper. Chine collé. Bound in cloth-covered boards. Signed and numbered by the artist. Rebecca Goodale: "Some prints cut out and attached on top of others to create illusion of wading at the edge of the sea and shore. There is also a two-page spread of chine collé larvae. This large clothbound book is read vertically, the pages moving up and down like the surf." Part of Goodale's extensive "Threatened and Endangered Species" series. Casco Bay Estuary: "Horseshoe crab spawning surveys were initiated in Maine in 2001 in response to anecdotal reports that populations were declining. This project involves collaboration among the Maine Department of Marine Resources, Bar Mills Ecological, Maine Coastal Program, and many other organizations to establish quantitative baseline population data to determine whether horseshoe crab populations are stable or declining. Approximately 50-70 volunteers collect data annually at sites ranging from Casco Bay to Frenchman's Bay. Volunteers measure water temperature and survey the number, clustering and location of horseshoe crabs along a transect during predicted dates of peak spawning activity typically associated with the new moon and full moon lunar phases of late May and June.
