First set of students sorting their final catch on the boat. |
The morning broke, and as the first brave set of greenhorns
awoke and prepared for the next few hours ahead of them. As they looked outside
to see what weather would await them, none were shocked to see the 15mph winds,
short showers of rain and the mighty two foot swells of the bay. None the less
all went bravely and upon the boat things did not go much better, unexpected
items came up in the first trawl, and for the second things went a little
smoother. After a much delayed return, they were greeted back to land with warm
sun, blue sky’s and the faces of the next group of students. This next group
crawled upon the 54ft aluminum boat and listed as the boats Captain, first mate
and NOAA scientist told them about the safety rules of the boat and what they
would be doing. The boat casted off the dock, the weather had cleared and
everything seemed well for the time being.

As the students pulled up to their
first trawling site, a CTD was released to record the salinity, temperature and
depth of the water below. The trawling net went out after the return of the CTD
and the weather took a turn for the worse, it started to poor rain and hail on
the students awaiting the nets return and the wind started to blow. It didn’t
let up as the net returned and as the students started to sort their catch and
record the size of any English sole and Speckled sanddab they had caught. Soon
after the catch was sorted the sun and blue sky reappeared, and two bald eagles
flew overhead, the boat moved onward to their next trawling point and half way
there they stopped to take another CTD sample. The boat turned sideways to the
waves and as it rolled back and forth in the swells, the students held strong
and once the data was retrieved they moved onward to their next trawl. The net
lowered and raised in what seemed like seconds but was really six minutes and
soon after sorting the students found a total of five different species. The
boat docked soon after and the tired greenhorns left to rest but only after an
hour all the students were back to lecture and lab. The end of the day came
around 6, and sunny weather ended the day for the students. Light traps were
set out that night by their teacher and TA and as the students lay in their
beds, the ocean was cooking up a new set of mysteries for them to solve.

A New Day
Monster WORM!! |
8:30 the
next morning three of the brave students went out with their teacher and TA to
go collect their traps from the night before. The first two came up with no
fish larvae but instead lots of Amphipods, crab megalopa, and decapods. The
next two showed the real monsters of the deep, four 25cm or larger polychaete
worms. These monsters both creeped out everyone and intrigued them at the same
time. There were four different types of fish larvae in them and as the
students brought the traps back to lab, they couldn’t help but think about the
long day in front of them. To start off the day, students heard a lecture about
how fishes feed and about the different types of sensory equipment they have.
After a quick thirty-minute break, a guest lecture on marine plankton ecology
which was given by Dr. Luo and another guest lecture on animal behavior by a
NOAA scientist. A half hour lunch break was had and students returned for a lab
on the days earlier catch and after 45 minutes of looking at the fascinating
life we had caught in our own back yard, a lecture on writing scientific papers
was given and the students all took a sigh of relief as their day was finally
over. A late night finished the day for the students who didn’t go home and a weekend
of homework and studying was what they had to look forward to.
