Boston Dock's Observation.
With a nice clear sky and light breeze from the ocean our class met again outside of the Marriot hotel at Boston Long Wharf . At low tide and temperature around 80 degrees we divided in groups of four and beginning our observation around the harbor. With the inter tidal zone exposed I saw what appeared to be rock seaweeds along the protecting wall. There were also evidence of brown and black seaweeds in different areas suggesting a longer exposure to the sun and occasional drying. The sand around the area looked rough and rocky . As we move along, the water seems clear with visibility about 3 to 5 feet enough to see green vegetation at the bottom. At the bottom I also spotted what appeared to be a green grab and small fish.
First site: Long Wharf North
We made a closer observation on our second location under the docks around the Boston towers. There we looked at species that lives under the floating docks and pillars. I observed different colors of vegetation ranging from green, orange, black and brown. The visibility was roughly 4 feet allowing us to see what appeared to be different colors of tunicate. Yellow tunicates were closer together and concentrated in one spot where as the orange tunicates were scatter around the pillar. We then move to the other side of the dock to look at a rope that was pulled out of the water holding different species attached to it. There were about 100 blue mussels attached together along with some light brown and green seaweed.

Around noon we moved to our third location at Barking grad dock. At that time the temperature was around 90 degrees and in groups again we conducted our last observation. Under the floating dock I found green and purple weed and orange sponges looking species. I also found oysters shell, blue mussels and greed crab. As I was pulling things off the dock I came across what appeared to be a green sea lettuce with small bugs on it. When I took a closer look with magnifying classes they looked like sea roaches and very small skeleton looking shrimp. I referred to my guide book for a more descriptive explanation and I found what they call northern sea roaches and linear skeleton shrimp. Once we gather enough data we compared notes as a group and ended the hands on observation for the day.
