Over the past three days, the interns have acquired a comprehensive knowledge of over 50 species of fish native to Bermuda waters. By conducting three different types of fish surveys, the interns have learned to apply their new knowledge to the field. 

On Tuesday, the interns conducted belt transect and roving diver fish counts at both Bailey’s Bay Flatts and Crescent Reef.

On Wednesday, they learned how to do stationary point counts along a 30 meter transect. They used this skill to observe fish density at Rock-up Reef and Hog Breaker.

In their own words:

“It rained the first day, but we still leaned valuable skills like how to determine what makes up the ocean floor by randomly placing dots on pictures then recording what was under each dot in each photo. We also started to familiarize ourselves with common Bermudian fish to prepare ourselves for the next day.
On Tuesday, we went out on R/V Rumline to two dive sites and it was a great experience because we did the transect line surveys which is what real scientist do, so that was cool.”

Also, former intern, Eliza Gardner, has been helping out with this MSI session!

24 Hours Cruise on the R/V Atlantic Explorer

Last Thursday I, Kätchen Lachmayr, education intern here at BIOS, was presented with the unique opportunity to venture aboard the Atlantic Explorer and join them on a short two-day cruise to Hydrostation S and BATS.

Saying goodbye to BIOS

The AE departed from BIOS at approximately 11am on Thursday, after a safety meeting where we were instructed on where life jackets were, how to deploy a life raft, and practicing how to put on a survival suit.  The there were a total of 22 people on this voyage, five of them were other BIOS interns: Michel Chang, Ashley Berry, Will Halliday, and David Picton. 

The first stop was Hydrostation, which took about 2 hours to get to from BIOS. Once the AE arrived at Hydrostation, a CTD (left) was lowered into the water, and down to 4,000 meters! On the outside of this contraption were about 40 jugs that open at different depths to collect the seawater. Inside one of the labs on-board there is a computer that displays the depth that the device is at, the temperature and salinity of the water. It took a total of three hours to collect all the samples. The water samples are then used in number of the different labs back at BIOS, including CDOM and biogeochemistry.

The next stop was BATS, 50 miles off the coast of Bermuda! When the AE arrived at BATS a similar operation was conducted and the CTD was again lowered into the water to collect samples, this time only to 1,500 meters.  By the time all the samples at BATS had been collected it was midnight. A few other samples were collected for various labs, however I was not awake to see them. In the morning, we began our voyage back to BIOS a six-hour cruise from BATS.

Thankfully we had calm sea during the whole trip. This was quite the experience! 

MSI Independent Projects

MSI Independent Projects

In the last three days of their internship, the interns completed an independent project where they studied a fish that was of particular interest to them. They had four dives to conduct their research and then discussed their findings on Friday in a short presentation. This project required them to design their own experiments, data sheets, and determine which tools they would need. 

Four-eye Butterflyfish

For Michelle’s project, she was observing what Four-eye Butterflyfish ate. She completed her project by following the Four-eye Butterflyfish and recording what they ate and how many bits of food they took per minute.

Ryan, JD, and Tyler were studying the territory size of the Yellowtail Damselfish. They did this by placing a small weight in what was believed to be the center of the fish’s territory. They then attempted to chase the fish away and measured how far the fish would go with a string attached to a float. The Yellowtail Damselfish never leave their territory so it was assumed that the distance the fish went was the length of the territory.

Jonas was studying the number of piscivores, or fish eating fish, seen per minute. He did this using two methods, baited cameras and roving diver. His research found that the roving diver resulted in a greater number and diversity of piscivore sightings than the baited camera.

Bermudian Interns for 2013 Summer at BIOS!

Meet the Bermudian Interns for 2013 Summer at BIOS!

Jecar Chapman, 21, recently graduated from Bermuda College with an associate in science degree, and is soon headed off to Dalhousie University in Halifax, Canada to study Biochemistry and Molecular Biology. This is Jecar’s fourth year in the Bermuda Program. As a Bermudian intern he is working with Dr. Andrea Bodnar to continue the investigation of sea urchins as a model for a stem cell theory of anti-ageing.  When Jecar is not in the lab he enjoys snorkeling and fishing. One of Jecar’s favorite quotes from the lab is:
“If you don’t fail enough your not trying hard enough” –anonymous

Meredith Bibbings, 19, is going into her third year at McGill University in Montreal, Canada. She is majoring in physiology with a minor in neuroscience. Once she graduates she is considering getting a masters degree or applying to medical school. This is her second year at BIOS. Currently, she is working to continue a project to identify the microbes within the fire sponge.  For this project she is trying to determine the communities of microbes surrounding and on the fire sponges, and if there could be a symbiotic relationship between the fire sponge and microbes. When she is not in the lab or studying she enjoys dancing and rowing.
Favorite math joke:
“Alcohol and calculus don’t mix, don’t drink and derive”

Rachel Barnes, 20, is studying at Bowdoin College in Maine. She is majoring in oceanographic science and economics. This is her first year here at BIOS. She is working with Natasha McDonald studying chromophoric dissolved organic matter, also known as CDOM. In studying CDOM, she is trying to figure out where it comes from and why light penetrates it in such a unique manner. One of her favorite things about BIOS is the diversity of the community. In her free time Rachel enjoys playing squash.
Favorite science joke:
“Two men walk into a Bar. The first man orders some H2O. The second man says good, I’ll have some H2O too. The second man dies.”

Ashley Berry, 21, is entering her senior year at Duke University where she is studying biology. Once she graduates she is thinking of pursuing medical school, or grad school for a masters in biology. This is her first year at BIOS. She is working with Natasha McDonald, using gas chromatography and mass spectrometry of Lignin, the compound that makes up the cell walls in plants. Her findings will be compared with CDOM findings to see if there are any similarities. When Ashley is not studying or working in the lab she runs track, as she competes with the Bermuda Jr. National team running the 1500 and 3K steeplechase.

William Halliday, 21, is a recent graduate from Bangor University in Wales where he was studying geography. This is his first year interning here at BIOS. Will is working on a new project with Dr. Kristen Buck and Dr. Andrew Peters, to identify metals in Sargassum seaweed. The goal of the project is to identify what metals Sargassum seaweed is bringing into the Sargasso Sea and how these metals are contributing to biomagnification within Bermudian ecosystems.  Outside of work Will enjoys rock climbing and gardening.

Michel Johnston, 19, is a second year student at Penn State studying meteorology. Michel became interested in meteorology when he experienced Hurricane Fabian first hand. Once he began studying meteorology, the more he learned about the topic the more interested he became. This is his second year as an intern at BIOS. For his current project he is analyzing sea surface temperature data that has been collected since the 1950s as part of BATS to see if there are any trends that indicate climate change. Michel has also completed a training program with the Bermuda Weather Service and is now a qualified Meteorological Technician/Observer.

Christiana Halliday, 20, is entering her final year a Plymouth University in England studying environmental science. This is her third year here at BIOS. Christiana is working on a new project where she is looking at the pigmentation of corals to see if they can be successfully transplanted to deeper depths. When Christiana is not studying or doing research she enjoys playing ultimate frisbee and can make excellent brownies.
