Students Collaborate on One-of-a-kind Coral Bleaching Study

Thanks to an award from the Rosenstiel School’s Graduate Career Development Fund, a collaborative, graduate student-led research team has a one-of-a-kind opportunity to study how corals recover from mass bleaching events.

Five students – Jay Fisch, Erica Towle, Crawford Drury, Phil Kushlan and Rivah Winter – from three different labs across the Rosenstiel School campus have come together to design and execute a field study of an important reef-building coral, Orbicella faveolata, commonly known as Mountainous Star Coral, that suffered during the widespread coral bleaching event at Horseshoe Reef in the Florida Keys during the summer of 2014.

Historic information previously collected at the site, combined with collections over the next year will allow the student team to study changes in coral symbiosis and metabolism and to measure individual colony response and recovery following a bleaching event. The research project will provide scientists with valuable new information on the relationship between recovery patterns and subsequent reproductive output.

“Recovery of reefs depends on both the recovery of the surviving individuals as well as the input of new individuals through reproduction,” said the students.

The students received a total of $3000 from the Graduate Career Development Fund. The students are Ph.D. candidates in Lirman’s Benthic Ecology Lab, Baker’s Coral Reef and Climate Change Lab and Langdon’s Coral and Climate Change Lab.

Rescue a Reef Update

It’s been over 2 years since Dr. Diego Lirman’s Benthic Ecology Lab at RSMAS began outplanting nursery reared staghorn corals (Acropora cervicornis) to degraded reefs as part of one of the largest Acropora restoration projects along the Florida Reef Tract. Today, those corals are making a significant impact on the structure and function of Miami’s reefs.

The University of Miami Rosenstiel School of Marine and Atmospheric Science began growing colonies of the threatened staghorn coral in underwater nurseries starting with only 200 small fragments collected from existing wild colonies. To date, UM’s nurseries have produced over 6,000 healthy corals. Beginning in 2012, over 2,500 staghorn corals were carefully transplanted to their new homes on local reefs in Miami-Dade County. Over 85% of outplanted corals have survived to become part of the natural habitat and have grown to equal 243 meters of new staghorn! That is over 603% more coral than was originally outplanted! This is a significant increase in the number of Acropora colonies on local reefs and will help bridge spatial gaps between existing populations to enhance sexual reproduction and genetic diversity.The Benthic Ecology Lab has learned valuable lessons from their initial restoration success and has developed methods and techniques to increase the survival and growth of outplanted corals. In addition, important informtion about nursery and outplant site selection, growth and productivity variation between genotypes, effects of predation, and recovery from bleaching have been investigated to provide researchers and managers with essential conservation tools for the recovery of threatened staghorn corals.

Exploring Marine Science Day 2014

Saturday October 25, 2014 marked the 12th anniversary of the Exploring Marine Science Day for middle school girls. The Consortium for Advanced Research on the Transport of Hydrocarbon in the Environment (CARTHE) partnered with the UM Rosenstiel School and the American Association of University Women (AAUW) to host this day of interactive learning. Fifty young women from across South Florida spent their Saturday with Rosenstiel’s female faculty, students, and researchers to get an up close look at what it is like to be a marine scientist.

IMG_1476IMG_1463

  • The girls learned about corals with Stephanie Schopmeyer and helped with coral restoration by planting coral (skeleton) fragments on special nursery plantforms.
  • The amazing women from Marine Geosciences never disappoint! Amel Saied, Anna Ling, Kim Galvez, and Carolina Bardaro taught the girls how to squeeze water from mud samples and they explored some of the amazing organisms found in the ocean.
  • The highlight of the day is always drawing blood from a toadfish with Dr. Danielle McDonald and her students. They learned about red and white blood cells, plasma, and stress hormones.
  • Rana Fine taught the girls about ocean acidification through an experiment in which the girls test the pH of sea water, before and after the addition of a carbonated soda.
  • Aplysia! CARTHE Outreach Manager Laura Bracken taught the girls about the importance of the amazing aplysia and the fascinating details of their life cycle, but the best part was actually getting to hold their slimy new friend.
  • The girls learned about density during a colorful experiment, mixing salt and freshwater with Meredith Jennings and Renellys Perez.
  • Josefina Olascoaga created a spinning ocean in the lab, complete with dyed ocean currents and eddies!
  • Dr. Lisa Beal completed the day with a powerful video of female oceanographers and a reminder to all of us, “Don’t let the boys have all the fun!”

Attendees had this to say about the event:

“Today’s program was awesome! I did not know there was so much science out in the ocean…”
“I love science and everything I did today was amazing”

“Today was one of the best days of my life!”

“I learned that there was a lot more to marine science than I thought.”

The activities are clearly fun and engaging but most importantly the girls left with a greater interest in science and knowing that anyone can be a scientist. Our scientists are also athletes, mothers, community leaders, and artists. According to the evaluations, the majority has an increased interest in studying science!

Thank you to all of the volunteers from CARTHE, RSMAS, and AAUW for making this day a success.

UM coral scientist studies at Centre Scientifique de Monaco

As I write this blog, I am looking out the window at the famous Port Hercule in Monaco and see all of the beautiful yachts and racing sailboats.  And the best part is – I’m in my office!  Allow me to back-track: I am a 5th year Ph.D. candidate in Dr. Chris Langdon’s lab here at RSMAS.  I study indicators of resilience to climate change stressors in Florida Reef Tract corals.  Two years ago I met Dr. Christine Ferrier-Pages at the International Coral Reef Symposium.  Christine is the director of the Coral Eco-physiology team at the Centre Scientifique de Monaco (CSM), and I have admired her work on coral feeding for years.  By maintaining contact with her after we met at the conference, and through another colleague of Chris Langdon’s at a French university, I was offered the opportunity to participate in a seven-week collaboration in Christine’s lab in Monaco.  Together, we are studying the combined effects of nutrient enrichment (eutrophication), coral feeding, and elevated temperature stress on coral growth and physiology.  The lab facilities here are unparalleled, and it is truly an honor and a privilege for me to complete the last chapter of my dissertation at this institution.

Here’s a little history about CSM: it was founded in 1960 at the request of Prince Rainier III, Prince of Monaco, to provide the Principality of Monaco with the means of carrying out oceanographic research and to support governmental and international organizations responsible for the protection and conservation of marine life.  Since the late 1990s, the CSM has been a leader in coral reef biology, specializing in biomineralization research and climate change effects on corals.  The ocean and the issues surrounding it have always been on the forefront of causes important to the royal family of Monaco.  In addition to the CSM, Monaco also boasts an extensive oceanography museum and aquarium which draws international attention.

So what has it been like to work here so far?  One thing I have found a little challenging is learning to run an experiment in another language.  While most of the researchers here speak English (their publications are normally submitted in English,) French is their native language and is most commonly spoken in the lab.  I speak conversational French pretty well, but I have to learn basic experiment terms in French; words like tubes, flow rate, and probe, to name a few, were all new to me in the French language.

For now, my post-work view is the Mediterranean Sea, but I know in a few weeks a sunset view overlooking Biscayne Bay from the Wetlab patio will be calling my name…

Until then,

The Future of Aquaculture

Juvenile Mahi-Mahi

Juvenile Mahi-Mahi

UM Rosenstiel School Professor of Marine Ecosystems and Society Daniel Benetti published an essay on the future of aquaculture in the current issue of The Journal of Ocean Technology.

“In the field of aquaculture, technology has evolved at an enormous pace during the last two decades. Advances in technology are allowing all of us involved in the field, from scientists to operators, to address and tackle most, if not all, contentious issues in aquaculture.”

“Modern aquaculture relies on advanced technologies to produce wholesome seafood for human consumption. Indeed, aquaculture has become as important as farming and agriculture, currently contributing over 50% of wholesome seafood for human consumption worldwide. Aquaculture production continues to increase exponentially and is the fastest growing food production sector, having surpassed beef production in 2012-13 (66 million metric tons vs. 63 million metric tons). “

Scientific Drones Help Understand Formation of Bahamas Islands

University of Miami graduate student Kelly Jackson and Camera Wings Aerial Photography recently teamed up to capture high-resolution photographs of remote islands in the Bahamas using specially equipped drones. The study is aimed at finding new ways to more precisely study the geological evidence preserved inside bedrock during critical events in Earth’s history.

“Drones are changing the way geologists map,” said Jackson, a Ph.D. student in the Marine Geology and Geophysics program at the UM Rosenstiel School of Marine and Atmospheric Science. “It is now possible to acquire high-resolution photographs and elevation data of the hardest to reach locations.”

From the deck of the John G. Shedd Aquarium’s research vessel R/V Coral Reef II, Jackson and her team launched this unmanned aircraft outfitted with high-resolution digital cameras and position loggers over the remote islands of the Exuma Cays. Their goal of the study is to look back in time at the formation of the islands, which was driven by rapid fluctuations in sea level 125,000 years ago during the Pleistocene.

Using this newly available data from the drone technology, scientists can develop more detailed 3-D maps of the complex carbonate deposits, which holds important information about what Earth was like during the last interglacial period, when warmer global temperatures caused glacial melting.

Jackson and her team are currently analyzing the data obtained from the drone mapping survey.
