Oceanography and ocean engineering

Navier Yachts, a company founded by two MIT graduates, has developed “a 27-foot long, zero-emissions all-electric hydrofoil yacht capable of flying above the water’s surface at 20 knots,” writes Bill Springer for Forbes.

A new study by MIT researchers finds that the oceans may begin emitting chlorofluorocarbons by 2075, reports Valerie Yurk for E&E News. “Even if there were no climate change, as CFCs decay in the atmosphere, eventually the ocean has too much relative to the atmosphere, and it will come back out," says Prof. Susan Solomon.

Graduate student Lauren Dykman speaks with Atlantic reporter Sabrina Imbler about her quest to investigate the life cycle of the deep-sea trematode, a type of parasitic worm.

Prof. Fadel Adib speaks with BBC reporter Gareth Mitchell about a new battery-free underwater navigation system that his group developed. Adib explains that one of the key developments behind the new sensors is that they can “harvest power from sound.”

MIT researchers have developed a new battery-free, underwater navigation system, reports Darrell Etherington for TechCrunch. “Ultimately, the system and future versions that are based on the same technology could enable future robotic submarine explorers to better map the ocean floor,” writes Etherington, “and perform all kinds of automated monitoring and sub-sea navigation.”

Prof. Fadel Adib has created a new underwater device that not only broadcasts and receives sound, but is also powered by sound, reports The Economist. In the future, Adib and his colleagues hope the device could be used to “transmit information about water temperature, acidity and salinity.”

Researchers from MIT’s Self-Assembly Lab have developed a system of underwater structures to help sand accumulate naturally and elevate islands and coastlines above rising sea levels, reports Jesus Diaz for Fast Company. “Strategically positioned according to currents, these structures will use the energy of waves to accumulate sand in different locations,” Diaz explains.

Fast Company reporter Jesus Diaz writes that MIT researchers have developed a computer model that shows that rising water temperatures will cause the color of the world’s oceans to change.

The Washington Post spotlights an MIT study examining how climate change will alter the color of the oceans. “Changes are happening because of climate change,” says principal research scientist Stephanie Dutkiewicz. “The change in the color of the ocean will be one of early warning signals that we really have changed our planet.”

A study by MIT researchers shows that climate change will have a significant impact on phytoplankton, which will cause the oceans to change color, reports Brett Molina for USA Today. The researchers “developed a model simulating how different species of phytoplankton will grow and interact, and how warming oceans will have an impact,” Molina explains.

CNN reporter Jen Christensen writes that a new study by MIT researchers finds that climate change will impact phytoplankton, causing the color of the world’s oceans to shift. “The change is not a good thing, since it will definitely impact the rest of the food web,” says principal research scientist Stephanie Dutkiewicz.

A new study by MIT scientists provides evidence that climate-driven changes in phytoplankton will cause more than half of the world’s oceans to shift in color by 2100, reports Barbara Moran for WBUR. Principal research scientist Stephanie Dutkiewicz explains that the color changes are important “because they tell us a lot about what's changing in the ocean.”

Writing for The Guardian, Jeff Nesbit highlights Prof. Kerry Emanuel’s research showing that climate change is increasing the risk of extreme storms. Nesbit explains that Emanuel found that the risk for extreme storms in Tampa, Cairns, and the Persian Gulf increased by up to a factor of 14 over time as Earth’s climate changed.

Boston Globe reporter Bette Keva spotlights SeaTrac Systems, Inc., which was founded by MIT alumni Buddy Duncan and James Herman, and has developed an autonomous, solar-powered boat. Herman explains that SeaTrac’s goal is to develop a boat that could be used on “dirty, dull, dangerous, or expensive” missions.

The Economist highlights Prof. Michael Triantafyllou’s work studying how seals employ their whiskers to detect their surroundings. Triantafyllou is using the seal whisker as a model for developing an underwater sensor that would, “detect the wakes of natural objects, such as fish and marine mammals, and artificial ones, such as other robots, surface ships and submarines.”
