Listen: Tropical Fish Are No Longer Just In The Tropics As Climate Change Affects Habitats
"As the climate changes animals are adapting along with it some land animals are moving towards the planet's Poles and higher elevations and similar changes are going on under the seas from thirty miles off the North Carolina Coast Jay Price of member station W.. UNC Reports on Tropical Fish. That aren't in the tropics. It's a sunny late fall morning on the dive boat. Midnight Express anchored thirty miles off the North Carolina coast in the back of the boat. Scientists launch an ice chest size underwater droll called remotely operated vehicle on a long tether. Maybe down this far offshore. There's nothing to see in any direction except the black blue sea directly under I though there's a lot going on the effects of two major changes for sealife maybe at work in one place a sunken ship. One of these changes is rising sea see temperatures from climate change the other something called Marine Organization and ongoing building boom in human made structures underwater things like dock pilings artificial reefs and the submerged parts of oil drilling platforms offshore wind turbines. These scientists have been finding fish more common farther south and these seem to prefer shipwrecks to say nearby rocky reefs. It's really interesting and we still don't understand fully why they may be enjoying these. This artificial sculptures avery. Paxton is a biologist with the National Oceanic and Atmospheric Administration inside the boat scientists. Concentrate trade on screen showing video from the drone. They're using to steer it around. have visuals of the floor. Per Second Orientate. The wreckage is a tanker torpedoed in nineteen forty two by German submarine. It's thick with sea life now a bustling marine village on an otherwise desert like seafloor in some of the fish here now or more typically found on the coral reefs of southern Florida and the Caribbean what we do know that some of them are at the very northern end. And they're rand or some of them even passing but they're normally documented ranges. Dr Paxton has been studying. Sea Life on North Carolina's numerous shipwrecks for years. And and one of the ause moving forward is whether or not if species are to be moving forward if you could use artificial structures to facilitate so make these corridors Assisi's us if they're moving forward. There's already been some well. Documented habitat shifts by some commercially fished species Black Sea see bass and summer flounder. For example that used to be more common off. North Carolina have moved north. That's caused problems for fishermen all along the Atlantic Coast Paxton than the other. Scientists are studying this wreck though to learn more about how various species interact. Not just those with commercial I we're nearing the phone structure about manship ten. Fica sorry the drone does a slow sweep down the side of the mangled ship. Picking his way through a lot of sharks. The big ones a species called San Tigers high definition cameras record video that later the scientists will use to identify and tally the fish on the run. One of the the main purposes of our mission today is to try to understand. How some of the re- Fisher responding to the presence of these large predators like San Diego Sharks after the first survey is done? The midnight express moves a few miles away to another wreck. A German submarine the youth. Three fifty. Two there are lots more sharks and clouds clouds of other fish to including one species that grabs their attention now as the NHL attention yeah. That's pretty cool in Spanish language Spanish Hog Fisher one of the tropical species often during surveys. The scientists don't even see the small warm water fish until they download the recordings from the drone. Finally the surveys done. RV's and service later on shore. They'll scrutinize that video. Chris Taylor another Noah biologist aboard says the scientists want to better understand the complex roles artificial reefs play for sea life without necessarily promoting brought us in deployment of artificial structures but it is a growing call by commercial recreational fishers alike. What we've learned in the study is it the type of structure you put out there as likely to attract different communities species and one application is whether it's possible to place the right kinds of structures in key places is to help different species whether it's those that fishermen wants target or tropical fish that needs stepping stones they head north in search of cooler water for for N._p._R.?
