The Nature Conservancy and its partners’ staghorn and elkhorn coral recovery project, including Lirman’s nursery in Biscayne National Park, will receive $350,000 to help save U.S. reefs.
The news was announced yesterday by the National Oceanic and Atmospheric Administration (NOAA), who also said that the money, which will come from the American Recovery and Reinvestment Act (ARRA), will be used to further develop large-scale, in-water coral nurseries and restore coral reefs along the southern coast of Florida and around the U.S. Virgin Islands.
The Nature Conservancy will serve as coordinator of the overall project; a project which will include the University of Miami’s Rosenstiel School of Marine and Atmospheric Science, as well as other academic, government and private entities.
The project goal is to grow approximately 12,000 corals in Florida and use them to enhance coral populations in 34 different areas.
Thanks to a system of underwater hydrophones, scientists have been able to document the presence of North Atlantic Right whales in an area where they were believed to have gone extinct.
The North Atlantic Right whale (Eubalaena glacialis), where even the name is a reference to it being the “right” whale to hunt, was heavily targeted by whalers during the 19th and 20th century and the entire species was on the brink of extinction when the moratorium on whaling was implemented in the 1960s.
Being an important whaling area throughout the 19th century, Cape Farewell Ground off the southern tip of Greenland was believed to have no surviving population of Right whales, but when scientists from Oregon State University (OSU) and the National Oceanic and Atmospheric Administration (NOAA) begun investigating the area using hydrophones, they recorded a total of 2,012 Right whale “calls” from July through December 2007.
“We don’t know how many right whales there were in the area,” says David Mellinger, assistant professor at OSU’s Hatfield Marine Science Center in Newport and chief scientist of the project. “They aren’t individually distinctive in their vocalizations. But we did hear right whales at three widely space sites on the same day, so the absolute minimum is three. Even that number is significant because the entire population is estimated to be only 300 to 400 whales.”
During the last 50 years no more than two Right whales have been sighted at Cape Farewell Ground, so even a figure as low as three during the same day is good news.
The project has been using five hydrophones engineered by Haru Matsumoto at OSU, configured to continuously record ambient sounds below 1,000 Hz over a large region of the North Atlantic. These underwater hydrophones are sensitive enough to record sounds from hundreds of miles away. The scientists used previous recordings of Atlantic and North Pacific Right whales to identify the species’ distinct sounds, including a type of vocalization known as “up” calls.
“The technology has enabled us to identify an important unstudied habitat for endangered right whales and raises the possibility that – contrary to general belief – a remnant of a central or eastern Atlantic stock of right whales still exists and might be viable,” says Mellinger.
Results of the 2007 study were presented this week at a meeting of the Acoustical Society of America in Portland, Oregon.
In addition to Mellinger and Clapham, scientists involved in the project include Sharon Nieukirk, Karolin Klinck, Holger Klinck and Bob Dziak of the Cooperative Institute for Marine Resources Studies – a joint venture between OSU and NOAA; Phillip Clapham, a right whale expert with NOAA’s National Marine Mammal Laboratory, and Bryndís Brandsdóttir of the University of Iceland.
Commercial, recreational and party/charter boat fishermen from Maine to North Carolina have all rallied together to deal with an out-of-balance population of predatory spiny dogfish sharks that threatens the recovery of New England groundfish and several others fish stocks living along the U.S. East Coast.
The newly formed Fishermen Organized for Rational Dogfish Management (FORDM) has requested the assistance of Dr. Jane Lubchenco, newly appointed National Oceanic and Atmospheric Administration head, in dealing with the predator.
Spiny dogfish
The disproportionate abundance of dogfish is not a new problem; as early as 1992 Dr. Steven Murawski, now chief scientist of the National Marine Fisheries Service’s, wrote “Given the current high abundance of skates and dogfish, it may not be possible to increase gadoid (cod and haddock) and flounder abundance without ‘extracting’ some of the current standing stock.”
That was over 15 years ago and the situation has not improved. On the contrary, the amount of dogfish now exceeds that of skates, and dogfish comprises over half of all fish taken in the annual trawl surveys carried out by the Northeast Fisheries Science Center.
The spiny dogfish can exceed 150 cm in length and preys on virtually all species of fish smaller than itself. Dogfishes can also create a problem for other species by competing with them for prey fish.
This remarkable abundance of dogfish is most likely the result of countless years of ever increasing over-fishing. Spiny dogfish is not an appreciated food fish and the depletion of other species seems to have favoured it greatly in these waters.
A research boat used by the National Oceanic and Atmospheric Administration (NOAA), a federal agency charged with protecting the endangered North Atlantic Right Whale, collided with one of the whales off the Massachusetts coast this Sunday.
The NOAA vessel Auk was on its way back from a research journey when a Right Whale surfaced just 10 feet in front of the boat. The boat collided with the whale and the propeller cut into the animal’s left tail fluke. According to NOAA spokesman David Miller, the lacerations on the left tail fluke did not appear to be life-threatening. Researchers followed the whale for about 45 minutes after the accident and it appeared to be OK.
The accident highlights how difficult it is to avoid whale collisions and how we must work even harder to learn new ways of keeping these animals safe from boats. Even with the special precautions taken by NOAA vessels, the calamity still happened.
“To me, if it can happen to NOAA, it can happen to anybody,” said Regina Asmutis-Silvia, a Plymouth-based biologist with the Whale and Dolphin Conservation Society. “Therefore, everybody needs to up the ante and up their vigilance and take the issue much more seriously.“
Ship strikes are currently the major threat to the North Atlantic Right Whale (Eubalaena glacialis). This year, a record number of calves were born in U.S. waters, but the population still comprises no more than roughly 400 animals.
A ROV (remote operated vehicle) owned and operated by the oil company Shell have caught video of a very rare squid while filming a mile and a half (two and a half kilometers) underwater on the drilling site known as Perdido in the gulf of Mexico. The squid known as a Magnapinna squid has a unique look due to the fact that it has “elbows” on its arms. Little is known about these enigmatic squids that can grow to be between 5 to 23 feet (1.5 to 7 meters) long.
A total of four species of these squids have been found so far but there are likely more species still waiting to be discovered.
Magnapinna pacifica was the first species to be described and was described in 1998 by Michael Vecchione of the U.S. National Oceanic and Atmospheric Administration (NOAA) and University of Hawaii biologist Richard Young based on juvenile squids. Michael Vecchione and Richard Young later released a report that showed that Magnapinna squids are common in deep sea areas around the world. (Below about 4,000 feet (1,219 meters).)
The second species, M. talismani, was described in 2006 and the year after a third species M. atlantica was described. Both these species have been found in the Atlantic.
The last known species has yet to receive a scientific name.
