New Tool Helps Fisheries Avoid Protected Species In Near Real Time

June 3, 2018 — New computer-generated daily maps will help fishermen locate the most productive fishing spots in near real time while warning them where they face the greatest risk of entangling sea turtles, marine mammals, and other protected species. Scientists developed the maps, the products of a system called EcoCast, to help reduce accidental catches of protected species in fishing nets.

Funded primarily by NASA with support from NOAA, California Sea Grant, and Stanford University, EcoCast was developed by NOAA Fisheries scientists and academic partners with input from fishermen and managers.

Using the swordfish fishery as an example, EcoCast incorporates data from tagged animals, remote sensing satellites, and fisheries observers to help predict concentrations of target species (broadbill swordfish) and three protected species (leatherback turtle, blue shark and California sea lion).

EcoCast will help fishermen, managers, scientists, and others understand in near real-time where fishing vessels have the highest probability of catching targeted species and where there is risk of catching protected species. In doing so, EcoCast aims to improve the economic and environmental sustainability of fisheries that sometimes inadvertently catch and kill sensitive species.

Getting conservationists and fishers on the same page

May 31, 2018 — Historically, fisheries and the conservation community have struggled to find common ground. The tension between one’s desire to turn a profit and the other’s to preserve endangered or protected marine species that can be killed as bycatch has made it difficult to find solutions that satisfy both. Now, a new online tool developed by researchers at San Diego State University in collaboration with the National Oceanic and Atmospheric Administration (NOAA) and other universities could win support from both groups. EcoCast, developed with funding from the NASA Applied Sciences Ecological Forecasting Program, provides computer-generated maps to help fishermen target productive fishing spots while alerting them to areas likely to harbor protected species.

“This is a really different way of approaching ,” said Rebecca Lewison, a lead scientist on the project from San Diego State University and senior author of the new paper. “EcoCast pioneers a way of evaluating both conservation objectives and economic profitability. Instead of trying to shut down U.S. fisheries, EcoCast is trying to help U.S. fishermen fish smarter, allowing them to meet their set quota of target catch and avoid unwanted bycatch.”

Current protection zones for  are static, meaning authorities declare a zone off-limits to fishermen for some duration of time. But weather and oceanic conditions are ever-shifting, with species constantly moving in and out of protected areas. When protection zones are out of sync with the animals they’re designed to protect, both fisheries and conservation lose.

On North Carolina’s Outer Banks, A Preview Of What Might Be In Store For Mass. Barrier Beaches

August 9, 2017 — The first truly global disaster resulting from climate change may come from rising sea levels.

The United Nations Intergovernmental Committee on Climate Change has projected sea level rise of 1 to 3 feet by the end of the century, and more recent estimates by NASA and other scientists have projected a rise of up to 8 feet.

In Massachusetts, the rising sea will mean more frequent flooding, more severe storms, and dramatic change.

It’s a problem we will share with every coastal community on every continent. A bit farther down the Atlantic Coast, there’s a place that’s on a faster track to where we too may be headed.

‘These Beaches Are Doomed’

Leonardo Da Vinci wrote that “water is the driving force of all nature.”

Fascinated by great storms and terrible floods, DaVinci would have loved the Outer Banks of North Carolina. Nearly 200 miles of low-lying, shifting sand islands link into a high energy system of waves and storms.

“These beaches are doomed,” says Orrin Pilkey, a professor at Duke University and an octogenarian prophet. “The buildings are doomed too.”

Traveling through a shanty town of triple-decker McMansions on stilts, motels and condos too close to the sea, we stop in the town of Nags Head. Pilkey predicts catastrophe in vacationland.

“The future is one of retreat,” Pilkey says. “It’s the only way to save the beach. It’s the only way to save the buildings.”

Idea to cut NASA’s role in climate science could be major loss for Maine, scientists say

November 29, 2016 — Maine scientists are decrying the assertion by a senior adviser to President-elect Donald Trump that the new administration will eliminate or dramatically scale back NASA’s climate research.

The scientists say the elimination of the agency’s earth science programs would be catastrophic for climate science research in Maine, impairing their ability to detect and analyze effects on fisheries, forests and agriculture. Maine is a hub of climate research – especially as it relates to the oceans – and the work relies on data collected by NASA satellites and processed by the agency’s experts.

“If we lose these data sets and capabilities, that will be a major loss to us being able to monitor and track changes here in Maine and in other areas that impact us,” said Andrew Thomas, a professor of oceanography at the University of Maine’s School of Marine Sciences, which receives more than one-sixth of its research funds from NASA. “Basically, you’re chopping off one of your arms and saying, ‘Carry on.’ ” The school’s Satellite Data Lab is using NASA data to analyze effects of melting ice in the Gulf of Alaska and to monitor marine algae production in the California Current.

Bob Walker, a former Pennsylvania congressman who serves as Trump’s space policy adviser, said in interviews last week that the administration would realign NASA’s budget, prioritizing exploration of “deep space” over space-based observations of Earth, which he has previously characterized as “politically correct environmental monitoring.” Earth observations would instead be made by the National Science Foundation or National Oceanic and Atmospheric Administration, two much smaller agencies with little experience or expertise in space-based climate monitoring.

What If We Had All Listened to NASA and Started Eating Krill?

October 5th, 2016 — Way back in 1977—the year Star Wars came out, British Airways launched Concorde SST service between London and New York, and Jimmy Carter signed legislation creating the Department of Energy—NASA published an exceptionally forward-looking report called “The Role of Aerospace Technology in Agriculture.” Its purpose was to figure out how to feed a ballooning world population given the Earth’s limited resources—using space-age technology. Oddly enough, amid high-minded discussions about the aerial application of chemicals and remote-sensing systems, was tucked this suggestion: Perhaps humans could subsist wholly—or partially—on a diet of krill.

The succinct proposal clearly fell to the wayside and remained buried in the NASA report until we happened upon it recently. It got us thinking: What if we humans had actually embraced this notion back in the day and had become a race of krill-eating beings? Was this forgotten report from the 70s a viable proposal for saving the future of mankind?

Krill, of course, are the tiny, shrimp-like crustaceans that are found near the rock bottom of the food chain. They feed on phytoplankton and—because they are protein-rich—are a primary food source for larger fish, which eventually get eaten by us. Although some nations certainly do make use of krill as a food stuff—the Japanese call it okiami, and Norwegians eat krill paste with crackers—in most of the world, krill is just used as fish feed in aquaculture. Vitamins are also made with their oil, and certain enzymes found in krill are used in various food and medical products. However, not eating them is understandable, too—krill are quite salty, and each crustacean’s hard exoskeleton must be removed before being eaten because it contains contains fluorine, which is toxic in high enough concentrations. But still, if humankind’s sustainability problems could be saved by krill, maybe we should figure out a way to use them as sustenance. Who needs Soylent or crickets if the oceans are filled to the brim with underutilized krill, right?

Evidently not.

As it turns out, the harvesting of Antarctic krill has greatly increased since the report was published, and conservationists are now increasingly concerned about its diminishing global supply. Not only do countless fisheries rely on Antarctic krill as feed, but demand for krill oil and its enzymes has skyrocketed. “It is well-known that many proposals in the 1970s were made to greatly increase food production from the sea—including harvesting krill and other zooplankton,” explains Boris Worm, a marine research ecologist and associate professor at Dalhousie University. “At the time, it was still thought that the sea could feed a rapidly growing human population, but by the 1990s, it became clear that wild fisheries could not be increased any more.”

NASA commits $6.5M to Gulf of Maine Research Institute for climate change education

October 21, 2015 — The Gulf of Maine Research Institute in Portland is receiving a $6.5 million grant from NASA to create a new educational program focused on science knowledge and problem-solving related to climate change.

The grant will allow the nonprofit organization to upgrade the technical infrastructure at its Sam L. Cohen Center for Interactive Learning in Portland to deliver the new educational content to the 10,000 Maine 5th and 6th graders who visit each year, GMRI announced Tuesday. The organization will also making the educational programing web-accessible to visitors in other science centers and classrooms in Maine and nationwide.

Through customization of the new content from GMRI’s educational program, LabVenture!, the programming will allow students to investigate how climate change is affecting their local region and the rest of the world. The five-year grant, which will begin Nov. 1, will be shared with national science education partners.

Work at GMRI will begin immediately, and new programming content is expected to be available for the 2018-2019 school year.

Virginia: Menhaden pilot retires, lets NASA crash his plane for science

August 23, 2015 — Bill Corbett spent decades flying his trusty Cessna 172 every workday out of Newport News and up and down the coast, searching out Atlantic menhaden for the commercial fishery.

A professional fish-spotter before retiring last year, Corbett and his aircraft flew together through storms and turbulence. Twice they almost went down in flames. Once, the little four-seater got struck by lightning.

“That airplane and I rode through some nasty stuff together,” Corbett, 63, said Thursday from his home in Poquoson. “And it held together for me. … It was a loyal machine for me, keeping me alive.”

Next Wednesday, their bond will break — literally — when Corbett watches his old Cessna swing and drop tail first from the big gantry at NASA Langley Research Center in Hampton and crash to the ground.

The plane is scheduled to become the third and final crash test article for a study on emergency locator transmitters, or ELTs — the beacons that transmit a crash location to search-and-rescue crews when a plane goes down.
