Underwater sound has a huge effect on marine mammals. That’s why it’s so important to pay attention to how much noise we as humans are creating. Sound travels fast and far underwater: #Repost@noaaocean
Have you heard of SOFAR? It’s an acronym that means SOund Fixing And Ranging transmission. SOFAR is an ocean “channel” that allows sounds to carry great distances.
Here’s how it works. Think of the ocean as consisting of various zones, or layers — sort of like oil and vinegar salad dressing before it’s shaken up—except that ocean layers occur due to differences in salinity (salt content) and temperature variations. Saltier water, and colder water, lie beneath less salty, warmer water.
TURN ON YOUR SOUND and enjoy this beautiful video by @taslishaw Next week is Superpod 6 and I’ll be posting a lot of killer whale content! #Repost@taslishaw
Two things are featured in this video that are not typical of Bigg's killer whales: high-energy surface behaviours and vocalizing. These two things are infrequent in this population presumably because both would decrease their chances of successfully hunting (marine mammal such as seals have excellent hearing and are always on alert for killer whales). Although, with the incredible numbers of these whales in the region as of late, we have been witness to more socializing, surface active, and vocal Bigg's killer whales, possibly more than ever before in recent history. This video is living proof!
All footage shot within the last week.
The big belly flop at the beginning is T065A2, followed by T036A1, T049A, and the little firecracker that is T036A3 (who was vocalizing at the peak of every breach!!).
The recording is of a post-kill T036As and T099s
(BBC News) - At least two suspected rhino poachers have been mauled to death and eaten by lions on a South African game reserve, officials say.
Rangers discovered the remains of two, possibly three, people in a lion enclosure in the Sibuya reserve.
A high-powered rifle and an axe were also found.
Sibuya reserve owner Nick Fox said in a statement on the reserve's Facebook page that the suspected poachers entered the reserve late on Sunday night or early on Monday morning . "They strayed into a pride of lions - it's a big pride so they didn't have too much time," Mr Fox told AFP news agency.
"We're not sure how many there were - there's not much left of them."

Happy Fourth of July from the bald eagle, national bird of the U.S. Though they're capable of capturing their own prey, they also scavenge many meals. They eat mainly fish, but also hunt mammals, gulls, and waterfowl. Bald eagles usually do not breed until four or five years of age and may mate for life. Both males and females work to construct the huge stick nests they live in, which are often reused and enlarged year after year. Eggs are incubated by both parents for 34 to 36 days. This species is a conservation and environmental protection success story, seeing an increasing population over the last 40 years in North America. In the late 19th century and first two thirds of the 20th century, the population seriously declined over most of their range. With the population in serious danger of disappearing, the bald eagle was one of the first species to receive protections under the precursor to the Endangered Species Act in 1967, the species was later delisted when deemed stable in 2007. This protection and the efforts that followed, along with the banning of the insecticide DDT in 1973 (which impairs normal egg development in birds of prey), are all responsible for today's more plentiful populations.
