Oceana hopes shark study will help reduce bycatches

November 17, 2017 — Between 63 million and 273m sharks are caught and killed every year, often as unintentional bycatch victims, the NGO Oceana said. But the conservation group hopes the use of technology demonstrated in a study released Thursday will help reduce that number, maybe leading to emergency hot spot fishing area closures or gear changes.

For more than three months in 2016, between June and September, Neil Hammerschlag, a professor at the University of Miami, and Austin Gallagher, a researcher at Beneath the Waves, another NGO, monitored the movements in the Atlantic Ocean — from the New England to the North Carolina coasts — of 10 blue sharks tagged with satellite tracking devices, according to an executive summary of the report.

Two of the sharks came in close proximity — within one kilometer– of likely fishing activity on no less than four occasions, the researchers found when they overlaid their movements with that of the more than 60,000 vessels tracked by Global Fishing Watch.

UM scientist awarded grant aimed to increase aquaculture production in the US

November 2, 2017 — University of Miami Rosenstiel School of Marine and Atmospheric Science (UM) Professor Daniel Benetti has been awarded $967,000 by Florida Sea Grant from the National Oceanic and Atmospheric Administration (NOAA).

The funding is just a portion of $9.3 million NOAA has slated for 32 projects around the country to help spur the development and growth of shellfish, finfish and seaweed aquaculture businesses. All projects include public-private partnerships and will be led by Sea Grant programs across the nation.

With each project, every two dollars of federal funding is matched by one dollar of non-federal funds, bringing the total investment to more than $13.9 million. UM successfully leveraged with matching funds from an ongoing research agreement with Aqquua, LLC, a US company investing in advanced technologies to further aquaculture development in the nation.

The projects include basic and applied research to improve efficient production of seafood, permitting of new businesses, management of environmental health issues, and economic success of aquaculture businesses.

NOAA considers moving Miami headquarters amid budget cuts

June 29, 2017 — The federal agency that oversees hurricane research and manages fisheries along the nation’s southeast coast faces an overhaul and potential downsizing that could cripple partnerships that have made Miami a leader in the world of marine and atmospheric science.

While unrelated, the timing of the two moves — possibly relocating the National Oceanic and Atmospheric Administration’s Fisheries headquarters from Virginia Key to St. Petersburg and pending budget cuts to the climate science program there — amount to a double whammy for the research hub and a brain drain for the region.

“It’s a big hit,” said Ben Kirtman, an atmospheric scientist at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science and director of NOAA’s Cooperative Institute for Marine and Atmospheric Studies or CIMAS. Kirtman fears a “tyranny of distance” would all but end collaborations that began when the Fisheries headquarters opened across the street from the university in 1965.

“In science, it’s very difficult to do interdisciplinary work. It’s a real challenge because you speak difference languages. And that’s where a lot of the big breakthroughs come from,” he said. “When you’re separated by floors in the same building, it’s hard to collaborate, let alone if you’re across the state.”

Built at a time when ocean science was rapidly expanding, the Fisheries headquarters on the scrubby island represented years of collaboration between the agency and Rosenstiel. After the university started a marine lab in 1943, federal fisheries officials opened offices first on the Coral Gables campus, then followed the school labs to Virginia Key. In 1972, a partnership was struck for the cooperative institute, which along with 13 other such agreements around the country provide the basic research for NOAA missions. In 2015, NOAA awarded $125 to CIMAS, which includes Florida International University and other university programs in South Florida, to continue its efforts that include weather research for the Oceanic and Atmospheric Research program.

More acidic seawater now dissolving bit of Florida Keys reef

May 4, 2016 — Seawater — increasingly acidic due to global warming — is eating away the limestone framework for the coral reef of the upper Florida Keys, according to a new study. It’s something that scientists had expected, but not so soon.

This is one of the first times scientists have documented long-term effects of ocean acidification on the foundation of the reefs, said study author Chris Langdon, a biological oceanographer at the University of Miami.

“This is what I would call a leading indicator; it’s telling us about something happening early on before it’s a crisis,” Langdon said. “By the time you observe the corals actually crumbling, disappearing, things have pretty much gone to hell by that point.”

The northern part of the Florida Keys reef has lost about 12 pounds per square yard (6.5 kilograms per square meter) of limestone over the past six years, according to the study published in the journal Global Biogeochemical Cycles. Over the length of the reef, that’s more than 6 million tons. The water eats away at the nooks and crannies of the limestone foundation, making them more porous and weaker, Langdon said.
