Saturdays Observations

Saturday's Observations

Location: Boston's Inner Harbor / Winthrop's Crystal Cove

Observation conditions: Partly cloudy, 72 Degrees, Light wind from the east

During the morning session we observed the sea life that exists in the area around the Long Wharf. We speculated whether sea life would thrive in this type of area that has had human influence vs coastal island sites. We observed what appeared to be plant life and mussels as well as moss growing on three different types of material - granite from the man made inlet, wood from the man made dock and metal from the cooling device used for the nearby restaurant.

The most intriguing question to me was whether the sunlight had an effect on the growth of the sea life, or was it an optical illusion as the sun illuminated the substance and it's appearance changed.

Due to a personal issue I needed to continue my investigation in Winthrop's Crystal Cove.

Tools used
Pen- Paper- Knife- magnifing glass

I was able to pull growing seaweed from under the dock, some from an area that was in direct sunlight and another from an area that was mostly in the shade.

When comparing the two samples in similar light on top of the dock I saw no visible difference between the two. Coloring of each as well as the texture appeared to be the same.

I am not totally convinced, but do believe that the sunlight has minimum effect on underwater plant life, based on how it appeared to me during my sample evaluation.

After the peer review activity conducted in todays class. I would modify the original post to include specific attributes of the sample specimen.

The size of the Seaweed was 7 to 8inches in lenghth. It was 3 inches in width. The color of the items viewed on the dock was a brownish green.

On future post I would state key observations up front, and would add coments to clarify why I was not convinced that my theory was conclusive. I should have stated that my sample size was to small to come to a conclusive decision and that I would need more data to get to that point.
