Scientists tracked a young #whale's journey before he vanished. What they learned could help save his species.
#Bishop’s story, from birth to presumed death, shows the extreme danger facing right #whales, which could be extinct in 3 decades if they continue to disappear at the present rate. Bishop’s species is not doomed to #extinction …but time is running out.
Bolsonaro appeared at the federal police in Sao Paulo on Tuesday to meet with officers, along with his lawyer and former adviser who was also present at the time of the alleged incident.
For years, great white sharks had been swimming off the shores of South Africa. Then, the creatures often turned up dead in the country’s beaches missing something critical — their livers. Science Alert points out orcas as the culprits, and discusses how the sharks reacted. https://flip.it/.IpSK3 #Science#GreatWhiteShark#Sharks#Oceans#Orca#Whales
The South Taranaki Bight is home to blue #whales, Māui and Hector’s #dolphins, kororā (little #penguins), and key fishing grounds. You may already know that it is under threat once again by the possibility of #SeabedMining. Trans Tasman Resources ( #TTR ) is seeking consent to #mine the seabed of the South Taranaki Bight - to dig up to 50 million tonnes of ironsands a year for over 30 years, dumping 45 million tonnes back onto the seafloor.
I saw a humpback whale in #Wales today which is not something I ever thought would happen. It swam 5m off the breakwater I was stood on. My pictures were pants but SeaTrust have some great ones on their fb. #Whales#HumpbackWhales
"At some #OffshoreWind farm construction sites, loud pile drivers are used to anchor turbine bases to the ocean floor.
But underwater noise and vibration can disturb #whales and other marine mammals swimming nearby.
One strategy is called a #BubbleCurtain. A ship lays a tube on the ocean floor surrounding the construction site. Air is then pushed through holes in the tube to create a vertical wall of bubbles that traps the sound of construction."
"Warming temperatures have led to melting ice cover. That has meant less algae, which grows on the underside of sea ice and which feeds the benthic amphipods that #whales eat. Less algae means fewer amphipods that whales need to survive."
> Microscopic #plastic particles have been found in the fats and lungs of two-thirds of the marine mammals in a graduate student's study of ocean #microplastics. The presence of polymer particles and fibers in these animals suggests that microplastics can travel out of the digestive tract and lodge in the tissues.
Slowly processing photos from #Alaska and here's one of my favourites so far. These are humpback whales engaged in bubble-net feeding and I think I can count eight in the photo but there's no way to be sure how many were on or below the surface. We saw this spectacle a dozen or more times during this whale-watching boat ride during our stop at #Juneau and it's a memory we'll cherish.
The humpback whale was de-listed as threatened in 2018. After bottoming out at 700 individuals, the North Atlantic population is now at around 13,000! Worldwide there are about 135,000 humpbacks. https://en.wikipedia.org/wiki/Humpback_whale#Conservation_status
not for the first time I've been part of a team doing the southern-most direct ocean observations on the planet... we have just emerged from the Bay of Whales (yes there were #whales). Its where #Amundsen took #Fram and set up base for his successful round trip to the pole. It was also mind-meltingly spectacular. We got to around 78o 40'S and took a temperature-salinity profile. Why wouldn't you do all you can to preserve this planet?
"Looks like they knew exactly what they are doing," Captain Dan Kriz told Newsweek after the orcas again hit his ship in the Strait of Gibraltar near Spain.
Sperm whales off the southern coast of Western Australia devised a clever, if smelly and gross, strategy to protect themselves from what could have been a fatal attack by 30 killer whales. Scientists were there to witness it, and Live Science tells us more: https://flip.it/U2Oq1_ #Science#MarineLife#Whales#Orcas#Animals
For #FossilFriday, here’s a big lump of a bone that occurs is so few species that sometimes even professional paleontologists will struggle to identify it.
