Field Notes
We got on the bus at 8:30 am and arrived at Todd’s Landing around 8:50 am At Todd’s Landing, we found a good amount of crabs. Then, we got back on the bus to head to Griffin’s Landing. At Griffin’s Landing, we went down to this tiny peninsula to put our quadrant there. We heard the waves crashing, the water rippling, and of course the rain. Once we started looking for crab, it smelled like saltwater. Once we finished our quadrant work, we went up to the lagoon and took out the third trap. We found three juvenile lobsters, a cunner fish, and a bunch of green crabs. Even though it was raining, we had a great time.
