You’re in the tropical South Pacific swimming with dozens of dolphins in cerulean waters sparkling in the
sun’s 90-degree heat. No, this isn’t a luxury vacation; this is your full-time job as a marine scientist. From large
marine mammals to the smallest species of plankton, from freshwater marshes to the deepest depths of the ocean,
fisheries scientists and oceanographers study all aspects of the marine environment. Research, more often than not,
requires scientists to be on location to collect data, so most scientists go to sea or otherwise do field research at
least once in their careers. “It’s an environmental science, so it combines a lot of different aspects: environmental
awareness with science with the adventure aspect,” said Evelyn Lessard, pictured above, biological oceanographer and
associate professor in the UW School of Oceanography. While marine scientists working at the UW are often employed in
the duties of teaching students and writing papers, they are by no means confined to their offices for the duration of
their careers. “I worked in this beautiful field station in north Wisconsin,” said Tim Essington, shown in the second
picture above, marine biologist and aquatic and fishery science assistant professor. “A lot of people were paying money
to stay in similar environments, and this was my job.” Click
Christian Shane and his second-graders are swimming with excitement. Shane, a teacher at McKnight
Elementary, is one of 13 Pennsylvania teachers who were awarded grants from the state Council of Trout Unlimited through
its "Trout in the Classroom Program," which lets students grow and study the fish throughout the school year and release
them in the spring. The first thing Shane did when he found out about receiving the grant was, "I called all my fishing
buddies," he said with a smile. Shane is an active fly fisherman and thinks his students can learn a lot from the
Fish have personalities. Ordinary Canadian brook trout exhibit different traits: some social, others not.
Some risk-takers, others scaredy-fish. And so on. University of Guelph scientists noticed the different personalities as
they sat by the Credit River, west of Toronto, watching trout feed. Then they scooped out the fish and ran them through
six days of personality tests in the lab, and even some swimming tests. And the revelation suggests an answer to an old
question: How can different species, with different types of behaviour, evolve from a single starting point? Click
It's no fish tale -- the two tarp-covered eyesores in the middle of the St. George Ferry Terminal waiting
room will each finally be filled with 1,400 gallons of water and 200 tropical fish. With any luck, the transformation
will occur in time for Christmas. The 8-foot-tall tanks were installed at the end of July, and it was expected they'd be
full of fish by last month. Now, months later, the empty boxes remain under wraps and surrounded by ugly sawhorses. Part
of the long wait was due to a nearly month-long curing process to ensure that the silicone adhesive sealing the
3-inch-thick acrylic walls of the tanks had dried completely. "Sometimes the devil is in the details," explained Borough
President James P. Molinaro, who funded the tanks with $750,000 from his capital program. He allowed as to how he's "a
little disappointed" that the process is taking so long, but he realizes the wait is necessary to "make sure it's done
at Otago University have revealed how a sea creature that often ends up on our plates has provided the key ingredient
for a medical gel. The gel extracted from squid, shown above, helps control scarring and bleeding. This can be used
during different types of surgery, especially tricky operations through the nose such as sinus operations. Around a
third of sinus operations have to be repeated because bleeding and scarring cause adhesions that block the sinuses
again. So Professor Brian Robinson and colleagues at Otago turned to the sea and the squid to find an answer to the
reoccurring problem. They discovered a way of creating a water soluble gel out of an extract from squid. "The first
thing we tried had the required biological properties. We didn't know but we were just lucky it did," says Professor
Robinson. Like a commercial glue, two ingredients are mixed at the last moment and then squirted over the surgical
wounds. "It stops the formation of adhesions and blood clots and it stays in place for about a week and then it
naturally dissolves," Professor Robinson adds. Click
