Rare species of North Pacific right whale carries a tune across the

first_imgCrance says the songs recorded are in many ways similar to the common gunshot calls. Federal researchers in the Bering Sea have released recordings of songs by some of the rarest whales in the world. While this is exciting news for marine science, it could point to heartache for North Pacific right whales. This isn’t to say North Pacific right whales don’t make sounds. “We know that they are in the southeastern Bering Sea in the summer,” she said, “but where do they go when they leave or if they leave the Bering Sea is still unknown.” First, it’s important to understand that North Pacific right whales are critically endangered. The name “right” whale is a vestige from the commercial whaling era,  when they were considered the “right” species to hunt. Slow moving and buoyant, right whales remained afloat after being killed. That’s the working theory for now and the one put forward this month in an article published in the Journal of the Acoustical Society of America. They were nearly wiped out in the early 20th century. “It’s difficult for us to know for certain why they’re singing,” Crance said. “But our best guess and our current hypothesis is that it appears to be some kind of a reproductive display.” “This behavior has not been documented yet in any of the other right whale species or populations,” said Jessica Crance, a NOAA marine biologist at the Alaska Fisheries Science Center’s Marine Mammal Laboratory in Seattle. In 2009, researchers in the Bering Sea first noticed these sounds during summer surveys. Long-term data from acoustic recorders over eight years showed evidence of right whale songs — something heretofore unknown for the species. “But they’re producing it in a very regular rhythmically pattern consistent manner. So the same number of gunshots, the same timing in between, and those patterns are repeated over and over for hours,” she said.center_img But Crance told CoastAlaska there’s so much about these whales that’s not understood. Now, with an eastern population of just 30 animals — they could be lonely. All of the confirmed recordings were from males possibly seeking female companionship.

So far it seems limited to the Bering Sea. “Within our population the most common call type is what’s called the gunshot sound,” she said. Even their migration routes and their breeding grounds remain a mystery. An eastern North Pacific right whale, the world’s most endangered great whale, spotted in the southeastern Bering Sea in 2004.

But contemporary threats persist — mostly vessel strikes and entanglement in fishing gear.last_img read more

Bungie and AMD working to fix Destiny 2 on Ryzen 3000 CPUs

first_imgPlayers have reported problems with running Destiny 2 on the recently released selection Ryzen 3000 CPUs. But no fear, AMD is working with Bungie on a hotfix.Having launched very recently, many eager players popped the AMD Ryzen 3000 line of processors into their gaming rigs hoping for improved visuals, performance and other bells and whistles. Sadly, if you were logging into Destiny 2 to tackle your daily quests, it might not have launched. This was the case for some according to Reddit and the Bungie forums. “Literally everything else works great on my new 3600 except for Destiny 2 which won’t even try to load” said one user, echoing an issue that many others seem to be having. At the time of writing, this problem seems to be isolated to Destiny 2 when using an processor in the AMD Ryzen 3000 line, which likely means a patch will need to be issued to fix things.Players have said that removing the component and returning to an older setup fixes the problem, otherwise Destiny 2 doesn’t seem to launch at all.  ‘AMD is aware of the recent report between the Destiny 2 game title with the latest 3rd Gen AMD Ryzen desktop processors and we are working closely together with Bungie to address this as soon as possible to enable gamers to fully enjoy their gaming experiences on AMD platforms, the company said in a statement to Trusted Reviews.To be fair, the AMD Ryzen 3000 CPUs have only just left the starting line, so some teething pains are to be expected. However, if you’re an avid Destiny 2 player with an eye for new hardware, this situation is a little unfortunate. Have you been having any issues with Destiny 2 lately?
