Greetings!
Chrys

Summer is a busy time for the entire nation's Sea Grant programs - MIT is no exception.

 

Among other responsibilities, our staff of engineers, biologists, mathematical modelers, educators, and social scientists is overseeing an ocean-engineering summer camp, assessing the spread of invasive species in our coastal waters, and advising on the implementation of new catch share policies for commercial fishermen.

 
Please read on for details on our current activities and announcements of events and awards.

THE OCEAN ENGINEERING EXPERIENCE
OEX '10 groupdome
















The MIT Ocean Engineering Experience (OEX), a new, week-long summer academic program, began Monday, July 25, with high school students from Georgia, Washington, Maryland and Massachusetts. OEX is jointly sponsored by the MIT Sea Grant Program and the MIT Center for Ocean Engineering.

 

OEX students, who were chosen in a competitive application process, were engaged in a real world scientific problem that took teamwork, science and engineering to solve. OEX students designed, tested and built an offshore floating wind turbine as well as designed, tested and built a remotely operated vehicle (ROV) that interacted with the turbine. The students successfully demonstrated their projects on Friday, July 30 at the MIT Sailing Pavilion. OEX team turbine and ROV pictured above!

CAPE ANN FRESH CATCH - COMMUNITY SUPPORTED FISHERY
CAFC '10 drop off crop
Cape Ann Fresh Catch, a Gloucester, Massachusetts based Community Supported Fishery or CSF, is well into its second year. CSF members give the fishing community financial support in advance of the season, and in turn the fishermen provide a weekly share of seafood during the harvesting season to shareholders. Cape Ann Fresh Catch offered its first subscription series in summer of 2009. The program proved so popular that additional subscription series were added throughout the summer and extending into the fall. A popular winter series was offered as well featuring winter shrimp. This summer, the program has over 900 subscribers. Cape Ann Fresh Catch is a project of the Gloucester Fishermen's Wives Association (GFWA), with support from MIT Sea Grant and the Northwest Atlantic Marine Alliance.
SEEKING MARINE INVASIVE SPECIES, DIDEMNUM, IN MASSACHUSETTS COASTAL WATERS
OIV on boat

A regional team of scientists is using the MIT Sea Grant AUV Lab's Odyssey IV vehicle to explore George's Bank to identify where the sea squirt, Didemnum vexillum, is found and gather information to better understand the impacts of this marine invasive species.  Didemnum vexillum is a nuisance throughout the region where it grows over many native species.  In deeper waters, such as Georges Bank, Didemnum may interfere with scallop settlement on the sea floor and prevent groundfish from feeding on polychaete worms that live in the sediment beneath the covering of sea squirt. A novel sensor is also being developed by the collaborators, from MIT Sea Grant, University of Connecticut and University of Maine, that will increase the efficiency (when compared to photographic imaging) of identifying where Didemnum is found.

HERRING MANAGEMENT IN THE NORTHEAST
Herring

Herring is the bait of choice for Maine's lobstermen.  A plethora of species, including humpback whales, seabirds, groundfish, striped bass and squid, forage on herring. Humans too have an appetite for herring. Researchers at MIT Sea Grant and UMass-Boston are leading a two-year effort to document the socio-cultural effects of herring management in the Northeast. Joining anthropologist Madeleine Hall-Arber of MIT Sea Grant and economist Sylvia Brandt of UMASS Boston in the project, funded by the National Marine Fisheries' Saltonstall-Kennedy grant program, will be five community researchers.  

CHRYSSOSTOMIDIS APPOINTED TO NAE/NRC COMMITTEE ON DEEPWATER HORIZON SPILL
Xian Luo

At the request of the Obama Administration, the National Academy of Engineering (NAE) and National Research Council (NRC) have formed a committee to analyze the causes of the Deepwater Horizon explosion, fire, and oil spill to identify measures for preventing similar accidents in the future. MIT Sea Grant director, Chrys Chryssostomidis, has been  nominated to this 10 member committee. For full press release click here.


MIT SEA GRANT TRANSFERS eSG SYSTEM TO WASHINGTON SEA GRANT

Washington Sea Grant was the lucky recipient of their own, customized version of MIT Sea Grant's electronic information system, eSG. The system will allow them to manage and track all projects and publications, from the initial call for proposals to the final submission of reports to the National Office, and web publication of all project and program results. Ben Bray, MIT Sea Grant's Technical Specialist, spent a pleasant week in Seattle installing and demonstrating the system. All the software components are widely-used standards: web browser, MySQL, and a FileMakerPro interface for management. MIT has been using eSG for almost two years, and Washington is scheduled to go live in January 2011.


MIT SEA GRANT'S SEA PERCH IN LA SPEZIA ITALY
SP underwater

July 2nd-4th the NATO Undersea Research Centre (NURC) located in La Spezia, Italy hosted a Sea Perch Teacher Training Workshop as part of the 5th Annual European Student AUV Challenge. This workshop resulted from a collaboration between the Office of Naval Research and MIT Sea Grant. Over the course of three days, nine teachers and three students from Northern Italy attended the workshop where they learned about the Sea Perch program and built their own Sea Perch vehicles. All teachers attending planned to incorporate the Sea Perch vehicle into their curriculum this fall. Additionally many of the competition teams and judges were able to observe the workshop and received information about both the Sea Perch program and other MIT Sea Grant projects.

FOUR MIT SEA GRANT PAPERS PRESENTED AT THE GCMS CONFERENCE IN OTTOWA
Xian Luo

MIT Sea Grant's Design Lab presented four papers at the 2010 Grand Challenges in Modeling & Simulation Conference, part of the 2010 Summer Simulation Multiconference in Ottawa, Canada. The papers investigated aspects of the modeling and design of a proposed all-electric ship for the US Navy. Contributing to the papers were MIT Sea Grant director Chrys Chryssostomidis, Prof. George Karniadakis, Julie Chalfant, Mirjana Milosevic, Brenden Epps and Xian Luo (pictured left).

 

The first paper presented an end-to-end simulation of an integrated power system for the all-electric ship, considering the prime mover (a gas turbine), electrical generator, DC power delivery system, propulsion drive (induction motor), and the propulsor. The second paper presented a study of several hybrid AC/DC electrical system configurations, considering electrical efficiency, survivability in various damage scenarios, and weight (which is correlated with both the production and operating costs of the vessel).The third paper presented a fast computational fluid dynamics (CFD) algorithm for the analysis of complex geometry flows, such as the flow through a proposed waterjet propulsion system for the electric ship. The fourth paper presented an open-source numerical tool for the design and analysis of marine propellers, which can be used to estimate the powering requirements for the propulsor of the all-electric ship.

DAN GOETHEL SELECTED FOR NMFS SEA GRANT FELLOWSHIP
Dan Goethel NMFS
MIT Sea Grant candidate, Dan Goethel of University of Massachusetts at Dartmouth, was selected for the National Marine Fisheries Service/Sea Grant Fellowship in Population Dynamics for his project "A Spatially Explicit and Tag-Integrated Stock Assessment Model of Yellowtail Flounder." The program supports Ph.D. students interested in the population dynamics of living marine resources and the development and implementation of quantitative methods for assessing their status.


DEAN A. HORN AWARD WINNER: JOSEPH CONTE
Joe Conte - Horn Award '10

MIT sophomore, Joe Conte has been awarded the 2010 Dean A. Horn Award for Undergraduate Study in Marine Research. The Horn Award  honors former MIT Sea Grant Director, Dean Horn, and his ideals of service, creativity, pursuit of excellence and tireless application to research.


Joe was nominated for his paper, "A Fast Starting Robotic Fish." A simple mechanical system was built to mimic the startle response of the most successfully studied fast-start specialist species, the pike. The body form of the mechanical fish in this work was modeled from a pike species. By using an accelerometer, placed at the fish center of mass, the faststart acceleration of the propulsion was measured. The propulsive efficiency of the mechanical fish was also calculated and a series of flow visualization tests using particle image velocimetry (PIV) techniques was conducted in order to study the flow patterns that accompany the high acceleration start.
