Bermuda Program Interns Part 3

Welcome back to our blog!  We would like to introduce 4 more Bermuda Program interns who attended BIOS this summer!

The Bermuda Program offers a unique opportunity for Bermudian students, ages 18 and older, to broaden their knowledge of marine and atmospheric sciences and learn about the daily operations of an active research station.  Since 1976 more than 130 young Bermudians have taken part in this exciting program, with many applying their summer experiences toward further university studies.  Beyond that, some Bermuda Program graduates have successfully translated their summer internships into employment opportunities at BIOS and other related organizations in Bermuda.  See more at: http://www.bios.edu/education/bermuda-program

Andreas Ratteray
Andreas is a rising junior at Stanford University majoring in Earth Systems and minoring in Middle Eastern Languages, Literature, and Culture.  This summer he is working with Dr. Gretchen Goodbody-Gringley (http://www.bios.edu/about/team-members/gretchen-goodbody-gringley/) in Lionfish research.  Andreas has been coming to BIOS since age 11 when he participated in the Waterstart program.


1. How would you describe the project you have worked on at BIOS?
I’m surveying the density of prey for Lionfish to help Gretchen figure out what is going on with the Lionfish.  Another intern is looking at the Lionfish density, and I am looking at the density of the fish that the Lionfish eat.  We are varying the depth of the field research sites to see what patterns appear when you dive on a shallow rim reef to a reef crest and then to a deep fore, a range of depth of 30 ft to 100 ft. 

2. Why did you decide on this internship?
I wanted to apply what I was doing in university and learn more about the environmental issues unique to Bermuda.  I’ve always wanted to work at BIOS because it is a privilege to find a world-class institute right here in my backyard in the middle of the Atlantic Ocean. 

3. Has your time thus far at BIOS changed your thoughts on what you might want to do in the future?
It is encouraging to see people for whom science is a career.  BIOS has shown me that you don’t have to be a professor in order to contribute to the wealth of scientific knowledge.


Rachel Barnes         
Rachel is a recent graduate of Bowdoin College where she double majored in Earth and Oceanographic Science and Economics.  For the past 2 summers she has worked with BIOS researcher Natasha McDonald to analyze Bermuda Atlantic Time-series Study (BATS) oceanographic data.  Read more about BATS here http://www.bios.edu/research/projects/bats/


1. How would you describe the project you have worked on at BIOS?
I’ve spent the last few weeks learning how to do multivariate data analysis, data mining, and time series analysis in a statistical software program called R.  I’ve mostly been analyzing large data sets (from BATS mostly) in an effort to understand trends in chromophoric (light-absorbing) dissolved organic matter (cDOM), nutrients, and various other water qualities over time and space. The overarching goal is to model large-scale datasets and to be able to interpret ocean processes.

2. Why did you decide on a Bermuda Program internship?
I really enjoyed working with Natasha for the past 2 summers in the Bermuda Program.  I also learned how to use R last summer at BIOS and have used the program more this year in a few different classes at my university.  I wanted to come back to BIOS to continue using the statistical software this summer.


Shane Antonition
Shane is working towards a Bachelor of Science in Environmental Science at Plymouth University in the UK.  This summer Shane is working with Dr. Mark Guishard to test the efficacy of shark oil weather barometers.  Read more about Dr. Guishard’s risk prediction work with RPI 2.0 here www.bios.edu/research/projects/rpi/  


1. How would you describe the project you have worked on at BIOS?
My project this summer at BIOS is to investigate the accuracy of shark oil barometers in predicting weather conditions. This is then compared to our modern metrological forecasting tools. In order to achieve this, I have set up a camera with two shark oil barometers, which take photographs every ten minutes. Then in comparing the behaviors of the oil to observed weather conditions, we hope we can determine both what causes the behavior of the changing shark oil, as well as how the oil reacts to the changing weather.

2. What did you hope to gain or learn from your internship, and did you achieve this?
I hoped to gain experience in running an experiment and further my skills in conducting a research project. While I've had to troubleshoot experimental issues, I've learned a lot that will help me in future projects and in the rest of my university degree.


Leandra Stracquadanio
Leandra is a Zoology major at University College Dublin.  This summer she is working with Natasha McDonald in the Bermuda Bio-Optics Project’s lab.   Learn more about the project here http://www.bios.edu/research/projects/bbop/

  
1. How would you describe the project you have worked on at BIOS?
My project is interested in all of the pigments that are produced by plankton in the sea, but in particular, chlorophyll. I’m comparing levels of chlorophyll from the open ocean to inshore samples and analyzing them, including the different conditions, such as oxygen and carbon dioxide.

2. What did you hope to gain or learn from your internship, and did you achieve this?
When I was first told about this project I was informed it would be mostly chemistry based, which being a Zoology major, it was an area in which I did not have much experience.  Therefore, right from the beginning, I hoped to strengthen my chemistry skills. I also wanted to learn about data analysis because that’s such a large part of any science career. I feel like I’ve really learned a lot in both those fields while working on research in the real scientific world.

Fitch High School, Cane Toads, and Cahows



For Connecticut science teachers Charmaine and Kevin, Bermuda has always been special.  The couple fell in love with the island during their honeymoon, and soon returned with groups of Fitch High School students.  The pair began a Bermuda ecology course in Connecticut, which culminates in a fieldwork-based trip to the island.  Now, after 18 years of bringing students to Bermuda through BIOS, the island still hasn’t lost its charm. 

During their week-long stay at BIOS, the Fitch High School students snorkeled at Whalebone Bay, learned about the conservation project at Nonsuch Island Nature Reserve, explored North Rock, and much more.  I was able to join the group on their trips to Nonsuch Island and North Rock to document their trips, and learn why they look forward to returning to BIOS each year.     

On Thursday afternoon I met the group down by the docks.  After the safety briefing, we headed out to Nonsuch Island in the Castle Harbor Islands Nature Reserve.  Nonsuch Island is a reserve and wildlife sanctuary where conservationist David Wingate has spent his lifetime restoring and helping bring the endemic Bermuda Cahow sea bird back from near extinction. 


I spoke with Charmaine and Kevin on the boat ride over about their experiences bringing students to BIOS. Both couldn’t say enough good things about BIOS, and explained how the program has a significant impact on the students that they bring. “The people at BIOS have been great,” Charmaine said.  “For a lot of kids this is the only time they get to go to Bermuda.  The students learn to appreciate different cultures, see the beauty of the island, and for a lot of students this trip is the first time that they have been on their own.”  

The pair explained that some of the students who participate in the trip return the next summer with a new group, and help by teaching some of the classes and mentoring the students.  Kevin said that this becomes a valuable leadership opportunity for the students. 

  

Soon we caught sight of the light turquoise-colored waters surrounding Nonsuch, and the students excitedly got their dry bags ready.  Because the water is too shallow to dock, the captain anchored a little off shore, and the students helped load up the kayak with their dry bags. We all jumped in and swam to shore as Kyla, the Program Assistant for BIOS Ocean Academy, brought the loaded kayak in with her.  Once the students were ready, Kyla began the walking tour of the island.  She stopped along the way to point out some of Bermuda’s unique flora and fauna.

Eradicating the invasive cane toads
At one point, Kyla stopped to point out a black plastic wall enclosing a pond.  She asked the students what function they thought the barrier served.  The students were quick to guess that it was to keep an animal out.  That animal, as we found out, was a toad.  


We were all in awe as Kyla explained that the cane toad, Bufo marinus, has been observed swimming all the way from the mainland in search of fresh water!  Amazingly, the cane toad can smell the freshwater across Castle Harbor. These determined toads are the same ones that Bermudians commonly refer to as ‘road toads’ because they frequently are seen squashed in the road.

David Wingate published a paper in 2010 describing the success of the barrier in eliminating the invasive cane toads from the island.  Wingate explains how the cane toads threatened the endemic Bermuda skink and the seriously endangered Bermuda petrel, or cahow.   To try and rid the nature reserve of the invasive cane toads, Wingate and his team came up with a “non lethal method of removing toads” by installing “a toad barrier around the freshwater pond, constructed of robust high density polyethylene (HDPE).”  Because the toads rely on freshwater as breeding sites, they were unable to breed and consequently captured by Wingate’s team during the night.  Amazingly, Wingate and his team carried out the nighttime toad raids for 5 years until all toads were removed before they reached reproductive maturity.  After the 5 years, an impressive 1,244 toads were returned to the mainland. 

The barrier remains to discourage any more toads from coming to the island and Wingate estimates that only one toad per year tries to migrate to Nonsuch.  Because that rogue toad can be captured quickly, Wingate reports that the toad is now gone from the island and that his research paper “is the first published report of a successful eradication of the species from an island with breeding habitat.” 

Devils Isle and Cahows
Further along in the walking tour, Kyla said that the reason that Bermuda was called Devils Isle was because of the screaming cahows that people heard from aboard the ships.  It was thought that their screeches sounded like ghosts of people killed in shipwrecks.  Kyla also explained that in the 1620’s there was a widespread famine on the island and the settlers essentially eradicated the cahow.  With her arms stretched out, Kyla said how the cahows would mistake humans (which they had never encountered before) as trees, and would land on their limbs.  This made the cahows an easy target for the starving settlers, who would simply pick them off their arms and legs and cook them.  

In less than 20 years of settlement, the Cahow declined to the point where it was thought to be extinct, a belief that persisted until the rediscovery of 18 remaining nesting pairs on four offshore islets in 1951.  A 15-year old David Wingate, who was with the group when they found the pairs, left inspired.  After university studies, Wingate returned to Bermuda, driven to help bring the Cahow back from extinction. 
Kyla showed us some of the artificial nesting sites that the Cahow Recovery Programme has installed in order to encourage Cahows to reproduce.  Although remaining critically endangered, there is now hope for the Cahow on Nonsuch Island.  Wingate's conservation and recovery program on Nonsuch Island has successfully increased the number of Cahow breeding pairs from 18 in 1951 to 92 pairs in 2010.  The Cahow Recovery Programme is now recognized as one of the most successful restoration projects for a critically endangered species, and was highlighted in the first World Seabird Conference in Victoria, British Columbia, in September, 2010.  
 

The BIOS experience
The students seemed to really enjoy the tour of the island, and got a chance to do some snorkeling before heading back to the boat.  Once aboard the boat again, I spoke to a few of the students about their experience at BIOS.  One student, Alex, said, “I think it’s cool to be around all of the scientists here, and see the type of work that they are doing.  It’s so interesting to hear about their latest research.”  Another student, Sam, had the opportunity to experience some of the friendly Bermudian spirit, “One thing that struck me is how nice the people are here.  They smile and greet everyone they see."


Lauren is on her second trip to BIOS and told me, “It’s an amazing experience to see a lot of things that most people don’t get to see.  It has been a really unique experience.” Lauren explained that her favorite part of her time at BIOS has been being able to go diving, “It’s so amazing that I get to have this opportunity and I’m only 17.”  It was Mackenzie’s first year at BIOS and also her first time out of the country. “This trip has changed what I thought I wanted to do,” she said. “ Now I am interested in pursuing a career in marine biology.”

It is evident that the love that Charmaine and Kevin have for Bermuda and for BIOS is now shared by so many of their students.  We can’t wait to welcome next year’s group, and show them all why Bermuda and BIOS are so special.
