Analyzing the Indian River

Today we left our spot on the dock at Drop Anchor and moved to Portsmouth, Dominica. While en route we practiced both the man over board and fire safety drills. Will spotted our man over board ring and kept watch until it was rescued by Ben and first mate Monika in the dinghy Irv. Then for our fire drill Bridget led us with the hose in putting the fire out on port bow. After our drills I made it up to the crows nest for the first time since I have been on Ocean Star. Aylee and I stayed up there for about an hour while the chefs made lunch and the boat made its way into Portsmouth. From the crows nest we spotted a huge turtle swimming next to the bowsprit as Brooke and Bridget sat bow watch. Once we arrived in Portsmouth we got ourselves ready for our Oceanography lab on the Indian River. For this lab we boarded two traditional rowboats, half the shipmates in one and half the shipmates in the other, and tested the temperature and salinity as we traveled three quarters of a mile up the river. Considering the Indian River is an estuary, we gathered some interesting data when testing its brackish waters, finding the salinity at the surface to be around 3.2 parts per thousand when the salinity two meters down could be 33.3 parts per thousand due to the density stratification of the fresh and salt water. For any fans of the Pirates of the Caribbean movies, the Indian River is also a river that was used in the second movie. There is a hut off one of the tributaries that appeared in the background. Day 50 ended with a cloudless sunset, dinner, and a Marine Bio class with Nick. It was a great day to begin our last month here in the Caribbean.
