With nitrogen pollution a perpetual concern for Vineyard waterways, two towns are hoping that a shellfish experiment will be the latest puzzle piece to fall into place.

Voters in Chilmark and Tisbury will be asked at their respective town meetings next week to fund pilot programs aimed at reducing nitrogen levels in two locations: Chilmark Pond and Lagoon Pond. Through the funding and a partnership with the Martha’s Vineyard Shellfish Group, test reefs of noncommercial oysters will be cultivated, in addition to beds of native ribbed mussels.

The Copenhagen climate summit has been much in the news for two weeks and the media is full of stories about rising carbon dioxide (C02) levels, increasing acidity of the oceans, drastic changes in weather patterns, the warmest decade on record, melting glaciers, rising sea water levels and coastal communities in imminent danger of inundation. And that’s just the tip of the melting iceberg!
