Eel Grass Survey

Eel grass is like the nursery for fish–it reduces greenhouse grasses and stores carbon.
You can find eel grass just outside the Harbor, out at the Glades, Whitehead, or around Sandy Cove.
Here's what eel grass looks like:
Here is the byproduct of our data analysis. We have found that by measuring the length, width
and number of the eelgrass leaves, reproductive shoots and wasting disease in a sample of
eelgrass, we can determine if the eel grass is healthy. Our job is to keep track of where healthy
and unhealthy eelgrass is in our own Cohasset Harbor. Our main worry to eelgrass health is wasting
disease. Wasting disease is a fatal disease that spreads to eelgrass. Once a shoot or leaf of eelgrass
is dead from wasting disease, their leaves turn black or gray, like the pictures above and below.


This is one of our student researchers diving into Cohasset Harbor with a Go-Pro
and quadrat to survey a new found patch of eel grass.
