Mudflat project updates

At College of the Atlantic, students have been developing protocols for measuring the pH on clamflats, and comparing different meters to see which ones are the most precise, and this fall will measure pH on several flats in Bar Harbor. One student, Katie O’Brien, has also buried clam pre-weighed clam at three different sites in look at rate of weight loss of shells as a measurement of the potential threat to clam growth from low pH on clamflats. Those clams are being collected in October and if the technique shows promise, the study will be expanded next year.
