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.

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.
