MSI - Meet the Summer 2012 Marine Science Interns:
Rawleigh Tucker Daniel Maguire
Jeral Jackman Joshua Stephens
Kori Jackman Megan Thresh
Our interns arrived with a great
enthusiasm to learn about animal life in the Sargasso Sea. On Monday, they began “Expedition
Sargasso” by practicing the point intercept method of data collection. This method involves laying down
30-meter transect tape along the reef and carefully recording the different
corals they find at each meter as they make their way along the tape. They went
to the dive site Arches along the South shore of Bermuda to collect their first
set of data.
On the way back to BIOS, the
interns participated in a plankton tow.
This involves trawling for plankton using a large wind-sock shaped
filter, then observing the collected plankton in a lab. Through microscopes, the interns were
able to identify a plethora of different organisms, including shrimp, arrow
worms, copepods, krill, and a vast array of fish eggs.
Today, our interns continued their
scientific investigation by collecting data using the belt and video transect
methods at North Rock, the largest coral reef in Bermuda. In addition to collecting data, the interns practiced underwater videography by filming along the path of their
transect lines. The interns were
able to take the data from the two days of research diving to create bar graphs
for both sites showing the distribution of coral colonies per meter squared for
the top 5 most common corals in Bermuda. The
students also practiced coral identification and are looking forward to playing
Coral Jeopardy tomorrow.
In their own words:
Daniel: Today I learned about different types of coral, and
the frequency with which we find those corals along the North Rock… I also saw
trumpet fish.
