Carrie
Rinderle's zoology course introduced her to some of the world's
most beautiful and fascinating marine animals. The more she learned
about them, the more enthralled she became. The problem was that
Rinderle had never been to the ocean! Michael Bautsch, on the
other hand, just couldn't let go of sponges. After hearing Dr.
Aparna Palmer talk about marine sponges, Bautsch was hooked. Sponges
are animals? Sponges produce toxins to prevent being grazed upon
by other animals? Most sponges are hard as rocks? Pretty soon
he decided that he really had to see one. So, when Dr. Palmer
announced that she was teaching an intensive, one-week course
on marine invertebrates on the Oregon Coast in the summer of 2004,
Carrie and Michael jumped at the chance to take it. In August,
Rinderle and Bautsch joined eight other Mesa State students in
traveling to Charleston, Oregon to experience the rugged coastline
of the Pacific Northwest firsthand. Housed on the quaint campus
of the Oregon Institute of Marine Biology (OIMB), Dr. Palmer and
her students immersed themselves in surveying the abundance of
life that exists on Oregon's south coast.
Day One began at six in the morning. Sunrise and the low tide
revealed a vast array of colorful animals hidden among the rocky
tidepools and seagrass beds at Cape Arago. Here, students discovered
iridescent sea slugs, purplish seastars, and, of course, bright
orange sea sponges. Afternoon took Dr. Palmer and her students
to the quiet, wooded trails of the South Slough Estuarine Reserve
at high tide. Sonya Ortega had spent the spring semester learning
about estuaries in one of Dr. Palmer's courses; now she and the
other students could see for themselves how an arm of the Coos
Bay estuary is a delicate interaction between the ocean and the
Coos River. After eating dinner together in their cottage at OIMB,
everyone adjourned to the classroom; there, a short lecture by
Dr. Palmer was followed by time allotted for studying the collected
organisms. Later, students participated in "night-lighting."
This unusual ritual involves submerging a lamp two feet below
the surface of the water and then waiting to see which marine
organisms would be attracted to the light. Minute sea worms at
the peak of reproduction were immediately drawn to the underwater
lamp. Once back at the lab, with the help of teaching assistant
and Mesa State alumna Corri Heiss, the students were able look
into a compound microscope and see the bright blue eggs held within
the bodies of these delicate, translucent creatures.
Each
day brought new discoveries! Day two took the students to a Charleston
area mudflat at low tide and a rocky jetty in Bandon, Oregon at
high tide. The morning of day three revealed a spectacular sandy
beach habitat made all the more picturesque by the sight of an
old lighthouse in the distance. Here, biology majors Gina Farrell
and Lindsey Anders saw living sand dollars for the first time.
That afternoon, the Mesa State group invaded the local docks to
sample the life that abounds on the submerged edges of the structures;
large, ivory sea anemones and bright purple feather-duster worms
kept the students occupied. Day four took the students out on
OIMB's research vessel, the Pluteus; a bottom trawl of the bay
yielded such animals as dungeness crabs and sunflower stars. Students
Kara Fossey and Jessie Rains were especially thrilled when the
boat started heading for the large swells on the open ocean before
returning to the docks. That night, lab time was spent finishing
up the exhaustive task of identifying the collected specimens
and preparing for the next day's oral presentations. By the end
of the intensive, one-week course, Colleen Cooper-Vanosdell and
Nichole Stephens, like the other students, had become experts
at using dichotomous keys to identify collected specimens and
had come to appreciate the diverse fauna that exist on the Oregon
coast. Never had they learned so much in such little time!
