Island Ferries Take on Role of Research Vessels Collecting Data about Nantucket Sound

31.08.2006
Ferries that connect Cape Cod and the islands of Martha’s Vineyard and Nantucket are taking on another role - research vessels.

Woods Hole Oceanographic Institution (WHOI) biologist Scott Gallager and colleagues have installed a package of sensors on the 235-foot freight ferry Katama to measure water quality and to photograph plankton as the ferry crisscrosses the western side of Nantucket Sound year-round, several times daily.

“Hitchhiking science on a ferry provides a terrific opportunity for us to better understand how water quality and ocean life change over time,” Gallager said. The measurements for the Nantucket Sound Ferry Scientific Environmental Monitoring System began in May.

With the interest and cooperation of the Woods Hole, Martha’s Vineyard and Nantucket Steamship Authority, which operates the ferry service between Cape Cod and the islands, Gallager and colleagues developed a sensor package to measure water temperature, salinity, oxygen, chlorophyll, and water clarity, and take images of plankton living in the water column. Real-time data from the sensors travel over a wireless connection to Gallager’s shore-based lab, where he and WHOI colleagues Steve Lerner, Emily Miller, Andrew Girard, Andy Maffei, and collaborator Kevin Fall from Intel Corporation make them available to scientists and the public on the project Web site, http://4dgeo.whoi.edu/ferries.

The WHOI team will be installing another instrument package on the Steamship Authority ferry Eagle, which runs between Hyannis and Nantucket on the eastern side of Nantucket Sound. Their objective is to build up a detailed, continuous portrait of changing water conditions and plankton communities in Nantucket Sound over long time scales.

Nantucket Sound is a triangular area of coastal ocean between Cape Cod, Martha’s Vineyard, and Nantucket and is known for its changing water conditions and diverse marine life. The cold south-flowing Labrador Current nearby collides with warm water in the relatively shallow Nantucket Sound, creating a perpetual front just inside the eastern Sound. As water shifts with the wind and the tides, warm-water and cold-water species are thrust into the same space. Waters loaded with nutrients, from septic systems and runoff along the developed Cape Cod coastline, also mingle in the Sound with North Atlantic waters that have far fewer nutrients.

Gallager studies plankton, the tiny and abundant swimming animals that serve as food for coastal fish and marine mammals. The numbers and proportions of different plankton in coastal oceans change with the seasons and ocean conditions, and Gallager is interested in the processes and their time scales that control those changes.

The availability of plankton can make the difference between healthy and undernourished stocks of commercial finfish and shellfish. Storms, nutrient runoff from coastal development, and the warming of coastal ocean waters could drastically alter the types of plankton that flourish in Nantucket Sound, and therefore the quantity and quality of food for fish, marine mammals, and ultimately people.

“A long-term archive of how conditions change in Nantucket Sound could provide an early warning about the health and function of coastal regions important to our economy and our quality of life,” Gallager said.

The Nantucket Sound Ferry Scientific Environmental Monitoring System project is supported by the Woods Hole Sea Grant program.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
