The National Oceanic and Atmospheric Administration published an updated look at coral reef bleaching around the world, saying that high water temperatures have persisted into an unprecedented third year and will cause an increased number of bleaching events..and that, unfortunately, there s no signs of this slowing down or stopping.Office Copiers & PrintersGet Free Quotes & Compare Copiers.Find the Best Deal & Save Today.buyerzone.com/CopiersThis newest update sheds light on the dire situation — NOAA says there s now a 90-percent change we ll see widespread bleaching among coral reefs near the Federated States of Micronesia and Palau, both of which are Pacific islands.Australia is one notable location, and NOAA says there are several places around the U.S. that will be hit…hard.In addition, NOAA says there s a decent possibility that the Flower Garden Banks National Marine Sanctuary, a deeper reefs region about 100 miles from Texas, will also be hit with the bleaching event.
Scientists have given us another reason to save the reefs -- to protect manta rays endangered by Chinese demand for its gills.A manta ray nursery ground at the Flower Garden Banks National Marine Sanctuary in the US has been discovered by scientists at the University of California, San Diego, the institution announced Monday.The sanctuary, managed by the National Oceanic and Atmospheric Administration, sits in the Gulf of Mexico off the coast of Texas and harbours healthy coral reef ecosystems that researchers suspect are used by juvenile rays to recover body temperatures after "accessing deep,cold waters off the continental slope," it added.In a study published in Marine Biology, the exploration team described the newly discovered ground as an "important habitat" for juvenile rays, which make up 95 percent of manta ray visits to the Banks.Given how rare it is to spot juvenile rays, Josh Stewart, the lead author of the study, decided to find out why it was such a regular occurrence at the Banks.Calling the discovery a huge leap towards understanding manta rays better, Josh Stewart, the lead author of the study, said: "The juvenile life stage for oceanic mantas has been a bit of a black box for us, since we're so rarely able to observe them.
A group of researchers led by Ph.D. candidate Joshua Stewart from Scripps Institution of Oceanography at the University of California San Diego and scientists from the NOAA Office of National Marine Sanctuaries have discovered what they say is the first known manta ray nursery in the world.The manta ray nursery was discovered at the Flower Garden Banks National Marine Sanctuary off the coast of Texas in the Gulf of Mexico.This is the first habitat of its type to be described in a scientific study.During his research, Stewart observed juvenile mantas while conducting research on manta population structure.Stewart says that the challenge is in observing juvenile manta rays, which is rare.He notes that identifying this area as a nursery helps to highlight the importance of conservation and management.
Tucked away in the warm waters of the Gulf of Mexico, the world's first known nursery for baby manta rays has been discovered amid the shallow reefs.Biologist Joshua Stewart, a doctoral candidate at the Scripps Institution of Oceanography in San Diego, noticed several juvenile mantas (Mobula birostris) while conducting research at Flower Garden Banks National Marine Sanctuary, about 100 miles (160 kilometers) south of the Texas-Louisiana border.Noting the rarity of this sighting, Stewart teamed up with sanctuary staff to determine whether this spot really was highly frequented by the little rays.The team combed through 25 years' worth of dive logs and photographs collected by the sanctuary's staff divers, according to a statement released by Scripps.The scientists used the unique markings on the undersides of the rays to identify them, much like matching human fingerprints.They found that roughly 95 percent of the mantas visiting Flower Garden Banks were juveniles.
Marine biologist Joshua Stewart was scuba diving in the Gulf of Mexico when he spotted a baby manta ray — an unexpected find, given that juveniles are extremely rare and seldom observed by humans.After analysing other divers’ juvenile sightings, he and his colleagues determined a specific section of the Gulf to be a nursery for oceanic manta rays, according to their study published recently in Marine Biology.“The juvenile life stage for oceanic mantas has been a bit of a black box for us, since we’re so rarely able to observe them,” Stewart, a graduate student at the University of California San Diego, said in a press release.The nursery could prove useful for better understanding baby manta rays, he said.The nursery is located around 100 miles south of Texas in the Flower Garden Banks National Marine Sanctuary, a 56-square-mile protected area in the Gulf of Mexico.It harbors giant manta rays in addition to corals, jellies, whales, sea turtles, and other animal species.
(Rice University) Extreme storm flooding in Houston washed human waste onto coral reefs more than 100 miles offshore. Rice University marine biologists found fecal bacteria on sponges in the Flower Garden Banks National Marine Sanctuary following 2016's Tax Day flood and 2017's Hurricane Harvey.
