Project ASCO (Assessing Seaweed via Community Observations)

The goal of Project ASCO (Assessing Seaweed via Community Observations) is to get interested participants out into the intertidal zone to collect data about rockweed while exploring the beauty of the rocky coast between the tides.

Rockweed (Ascophyllum nodosum, or “Asco”) is the dominant species in most of the rocky intertidal zone of Maine and provides habitat for other species living in and visiting the intertidal zone. Rockweed is currently harvested in Maine and sustainable management requires knowledge of the total amount of rockweed throughout the state. Participants in Project ASCO can help answer the question, ”How much rockweed is there?”

Data collected by Project ASCO participants will be analyzed and shared by scientists at Schoodic Institute to inform resource management. Along with rockweed, this project allows for learning more about other seaweeds, periwinkles, mussels, crabs, birds, and the occasional seal or whale.
