THE NEW DIMENSION IN
UNDERSEA EXPLORATION

Compiled by
Robert N. Ginsburg MGG

“AUVs, Autonomous Underwater Vehicles will revolutionize sea floor observing, data collection and mapping” so argued Assistant Professor Mark Grasmueck six years ago in his seminar as part of being interviewed to join MGG. His personal confirmation of that prediction finally came six years later when NOAA’s Ocean Exploration Program funded ten days of AUV time to map deep-water coral reefs in the Straits of Florida. Over the last forty years numerous specimens of deep sea corals living at temperatures below 12° C have been recovered by dredging from depths of 400-800 m in the Caribbean (e.g. RV Gerda and RV Columbus Iselin). Until recently, this extensive collection of samples and observations lacked a proper geomorphologic context because existing bathymetric charts could not resolve these coral reefs. Research on these unusual reefs was stalled and efforts to locate and protect these fragile and slow growing oases were stymied by the lack of charts with adequate resolution. To fill that critical gap, Grasmueck assembled an interdisciplinary research team from RSMAS and other Florida institutions to recover a new generation of sea floor images. He and Professor Gregor Eberli selected five sites in the Straits of Florida. The AUV (Fig. 1) was powered by a fuel cell providing a mission endurance of more than 55 hours; it cruises at 1.8 m/s scanning the seafloor in parallel lines spaced 200 m apart like a lawn mower. The AUV mapped the five sites ranging from 14–48 km2 in 590–875 m water depth acquiring 1–3 m resolution bathymetry and acoustic backscatter together with subbottom profiles, current vectors, salinity, and temperature. The processed multibeam data rendered a three-dimensional image of the seabed in unprecedented resolution and show hundreds of coral mounds with heights of 1–120m (Fig.2).

Figure 1

The 40 m cruising altitude of the AUV was too high to record images verifying living corals on the mounds. To fill this gap, Grasmueck designed and assembled a low cost drop camera (Fig 1) just weeks before the AUV cruise. The images from near the peak of the largest mound show living corals, while the slope facing north is covered with dead coral rubble (Fig.2 ).

Just how valuable the high-resolution AUV images are was evident in May when they guided the Johnson Sea Link Submersible of the Harbor Branch Oceanographic Institute. For the first time the dive track could be precisely planned with the 3D AUV images. During the dives the submersible’s position could be followed continuously and even directed from the bridge of the Seward Johnson Research Vessel. Dr. John Reed, a leading biologist of these reefs and Dr. Shirley Pomponi, Head of Harbor Branch and a specialist on deep-sea sponges, both realize how essential these new maps are in guiding the exploration for medicinals in deep sea marine animals. “We could not imagine being without such high-resolution maps in future submersible dives”. The AUV images and oceanographic data are an entirely new foundation for answering questions about coral mound distribution and morphology, biodiversity, and they can guide future exploration and measures to protect these remarkable reefs.

WOMEN IN SCIENCE

RSMAS held the 4th Annual Exploring Marine Science program for 6th to 7th grade females on Saturday, November 11, 2006. For the second year, more than 100 girls from South Florida registered for this event and attendance had to be capped at 50. This year we hosted a very bright and enthusiastic group representing 22 area schools and the home-schooled population.

Hands-on activities were led by Dr. Lisa Beal (MPO), Dr. Lynne Fieber (MBF), Dr. Rana Fine (MAC), Dr. Lora Fleming (MBF/OHH), Dr. Danielle McDonald (MBF), Dr. Lisa Pitman, Tauna Rankin (MBF), Katie Shulzitski (MBF), and Dr. Paquita Zuidema (MPO). Marilyn Brandt (MBF), Deanna Donohoue (MAC), Janet Genz (MBF), Silvia Gremes-Cordero (AMP), Jennifer Grimm (MAF), Julie Hollenbeck (MBF/OHH), Lucy Hynes, Mandy Karnauskas (MBF), Kat Loftus (MBF), Melany McFadden (MGG), Maaike Petrie (MGG), and Terry Pitman volunteered to assist with the day’s activities and interact with the visiting females.

Exploring Marine Science was developed to bring awareness to young women of the increasing opportunities as marine and atmospheric scientists in industry, academia, government, and society. The American Association of University Women (AAUW), whose mission is to promote equity for all women and girls, lifelong education, and positive societal change, partners with RSMAS to present this event.

ENVIRONMENTAL RESEARCH STAR:
MAC STUDENT WINS EPA SCHOLARSHIP

For Deanna Donohue, it was love at first water sample. A Ph.D student in the Marine and Atmospheric Chemistry Division of the Rosenstiel School of Marine and Atmospheric Science, Donohue’s dedication to research has most recently earned her the prestigious Environmental Protection Agency’s (EPA) Science to Achieve Results (STAR) Fellowship for Graduate Environmental Study.

Initiated in 1995, The EPA’s STAR fellowship program was created to encourage promising students to obtain advanced degrees and pursue careers in an environmental field. Students are selected on the merits of their individual research projects within a variety of environmentally related research areas. Since its inception, nearly 1,200 fellowships have been awarded through the STAR program.

Donohue is currently working on a project that aims to develop a way to experimentally measuring rate coefficients for the reactions of elementary mercury and halogen species, research that may have global implications in air quality. Her work has taken her to conferences in Europe and most recently, fieldwork in Hawaii using the Aerosol Sodium Detector (ASD), an instrument developed at the Rosenstiel School, to measure size distribution and composition of sea salt aerosols in marine air. The STAR program will provide Donohue funding of $111,000 over a period of 3-years to assist her with research expenses.

The U.S. Environmental Protection Agency (EPA) offers graduate fellowships for masters and doctoral level students majoring in environmental fields of study. Doctoral Students may be supported for a maximum of three years, usable over a period of four years. The fellowship program provides up to $37,000 of support annually for each fellowship, with plans to award approximately 65 new fellowships by July 20, 2007.

Donohue graduated from Augustana College in Sioux Falls, SD with a degree in Physical and Quantum Chemistry. She has been a member of the graduate student organization executive committee, a bartender at the Rosenstiel School bar, and currently serves as one of the managers of the student Bar.


IMPROVEMENTS TO THE MSC AQUARIUM

Hopefully you've noticed the recent improvements to the aquarium in the MSC Lobby near the entrance to the Commons. The aquarium has been maintained by MPO student Mike McGauley for years with startup funds from numerous patrons and continued funding from the RSMAS Advancement Office. As of recent, MBF student Tammy Laberge MacDonald and her husband, Glenn, have joined in. Together, they've introduced a reverse osmosis system, installed new lights and are slowly integrating new marine life. Others at RSMAS have contributed funding, advice and support and it certainly shows. We hope you all enjoy the ongoing improvements!


UNITED WAY THANKS YOU!

Thank you to all who contributed to this year’s United Way Campaign. RSMAS surpassed its fundraising goal of $26,400 this year with total giving of $26,797.

As a result, the University of Miami continues to be recognized by United Way of Miami-Dade County as a “Good Works” employer, a select group of organizations having year-round community involvement. Together we are providing funds to numerous community organizations to help kids and families lead successful lives, to improve health and independence, to respond to emergency and basic needs, and to encourage neighborhood and civic involvement.

Alumni Lecture

MARINE MAMMAL SCIENCE AND POLICY:
WHERE WE HAVE BEEN AND WHERE WE NEED TO GO

Rosenstiel School Auditorium
Wednesday, January 24, 2006
5:30 p.m. Reception
6:15 p.m. Lecture

Dr. John E. Reynolds, III
Chairman, Marine Mammal Commission

In the United States, interesting feedback exists between marine mammal science and policy. Within the past thirty or so years, roughly since the passage of the Marine Mammal Protection Act and the Endangered Species Act, some marine mammal species and stocks have recovered well. However, there remain some deficiencies in terms of marine mammal science and management if these animals and the ecosystems on which they depend are to be conserved well into the future. This presentation will cover some of the critical research and management needs.

John Reynolds graduated Cum Laude with Departmental Honors in Biology from Western Maryland College (now McDaniel College) in 1974. He earned his M.S. and Ph.D. degrees in Biological Oceanography here at RSMAS in 1977 and 1980, respectively. His thesis dissertation dealt with behavioral ecology and functional morphology of manatees. Following graduation, he served for more than twenty years as Professor of Marine Science and Biology and Chairman of the Natural Sciences Collegium at Eckerd College in St. Petersburg, Florida. He was integral in establishing Eckerd’s renowned marine science major. In 1989, he became a member of the Marine Mammal Commission’s Committee of Scientific Advisors on Marine Mammals and in 1990, became chair of the Committee. John has served as Chairman of the Marine Mammal Commission since 1991 and co-Chair of the IUCN Sirenian Specialist Group since 2001. He was elected to serve as President of the International Society for Marine Mammalogy from 2006 to 2008 and currently works for Mote Marine Laboratory in Sarasota, Florida as Senior Scientist and Manatee Research Program Manager. John is a member of Phi Beta Kappa, has received awards for his teaching, leadership, and scholarship, and has published nearly 200 papers, abstracts, and books. Although most of his research involves subtropical and temperate species, his significant efforts in the Arctic recently led to his being given the Eskimo name, Emuqtannee.

RSMAS and Harbor Branch Oceanographic Institution alternate hosting NOSB each year. A high school “Jeopardy-like” competition, NOSB is designed to enhance students’ knowledge of math and science as they relate to the ocean and prepare the next generation of marine scientists, policy makers, teachers, explorers, researchers, technicians, environmental advocates, and informed citizens for the challenges facing our blue planet. NOSB fosters collegiality and teamwork, competition, imaginative thinking and factual recollection. It also allows students to work side by side with experts in a wide variety of settings. This competition is intended to increase knowledge of the oceans on the part of high school students, their teachers and parents, as well as to raise the visibility and public understanding of the national investment in ocean-related research.

NOSB is nationally coordinated by the Consortium for Oceanographic Research and Education (CORE), a Washington DC based organization, representing 52 member institutions comprising the nucleus of federal, academic and industrial marine research and education efforts, in partnership with the National Marine Educators Association.

Volunteer training sessions will be held next week to make sure that everyone knows what to do and when to do it.
