The Navy have been blasting the sea with louder than rock concert sounds, hunting for Red October. Apparently the U.S. Navy hasn't done enough to ensure its sonar technology isn't hurting whales tho. Regardless this decision being overturned, the Navy had already planned to phase out much of the harmful sound.

“The Court of Appeals understood that the Navy can do more to reduce the risk of its powerful long-range sonar, especially in the vast reaches of the ocean where too little is known,” Michael Jasny of the National Resource Defense Council, one of several organizations behind suit, said in a statement. “Ignorance is no excuse for inaction where commonsense safeguards recommended by the government’s own scientists can prevent avoidable harm.”
The court’s ruling will send both parties back to a district court for further consideration. But time may well run out on the NMFS’s decision anyway; it expires in 2017. The Navy has already agreed to limit its use of sonar in certain locations starting in 2018. Soon, the only waves in the ocean will be the natural ones made of water, not man-made ones that come from sound.

Robyn Malcolm captured this wonderful photo of a fur seal surfing on a humpback whale off Eden, Australia.
"We'd seen some amazing whales coming out of the water, everything was happening so quickly," Malcolm told the Sydney Morning Herald. "And it was when I went back through the photos that I realised I had actually captured the seal on top of the whale."
Geoff Ross, a whale expert at New South Wales National Parks and Wildlife Service said the only other time he'd heard of this happening is when a seal was attempting to escape an orca. Read the rest
Humpback whales doing what they do, off Moss Landing, California. They kayakers were fine. From the YouTube post:
On our 08:00 am Sanctuary Cruises whale tour, just outside the harbor in Moss Landing, two kayakers on a tandam kayak were almost crushed to death by a massive, near full-size humpback whale. We stopped to see a large aggregation of humpbacks feeding and carrying on with random acts of hijinks. There were also a lot of kayakers right in the middle of it all. Humpbacks were coming up next to and in the middle of many kayakers. It was amusing. It's all fun and games until someone gets jumped on. The next thing we knew, this thing launched right on top of these two kayakers. That was heavy. The video was shot by Sanctuary Cruises passenger Larry Plants.

Humpback whales with albinism are extremely rare, so it was a real treat when one appeared off the coast of Australia this week. Read the rest
Did you enjoy Ecco the Dolphin, but wish it had allowed you to commit mass murder? Then Pequod might be for you.
I have taken whale-watching boat rides off Newport Beach many times, and seen many beautiful things. But there's always new beauty nature has ready to surprise us. Read the rest

Mammal penises, including those of cetaceans, are pretty easy to find, while vaginas are more difficult to examine; historically, accounts of animal reproduction have emphasized the features of penises and theories of sperm competition, but a burgeoning scientific emphasis on whale vaginas is revealing structures and strategies that are amazing and wonderful.

Icelandic news outlets are reporting that an Icelandic whaling company, Hvalur hf, "caught its first fin whale yesterday evening," after sailing out yesterday with two boats, both due back in port today.
Fin whales are the second-largest whale, and are classified as an Endangered species.

Ambergris is often referred to as "whale vomit", but that's not really correct. A more accurate analogy would be to say that ambergris is like the whale equivalent of a hairball. It's produced in the whale digestive tract, possibly to protect intestines from the sharp, pointy beaks of squid — you'll often find squid beaks embedded in the stuff. Most of it gets pooped out. But the big chunks of ambergris have to exit the other direction. In the human world, these lumps — which have the consistency of soft rock or thickly packed potting soil — are famous because we use them to make things like perfume. The ambergris washes up on beaches, people collect it, and sell it to make cosmetics.
Anyway, that's what usually happens. Recently, a dead sperm whale washed up on a beach in Holland and the conservationists who dissected it found a huge quantity of ambergris in the animal's intestines.
That news made me realize that I'd never actually seen a picture of ambergris before, so I went hunting around to see what the stuff looked like. That's a photo of a lump of ambergris, above. But it's not really indicative of what ambergris looks like all the time. In fact, as far as I can tell, the stuff comes in a wide variety of shapes and colors — ranging from stuff that looks like small brown pebbles to yellow-green globs covered in bubbly nodules. The diversity is worth perusing. This website, for a company that buys and sells ambergris, has several nice photos. Read the rest
The 52 Hertz Whale
is the cetacean equivalent of a pop-culture phenomenon — a strange creature, known only through recording of whale songs picked up in the Pacific Ocean, who seems to not be a part of any identifiable whale group. Also known as The Loneliest Whale in the World it is a source of pity and fascination among the general public. At PLOS Blogs, Hannah Cheng has a three-part feature on what we do and don't know about the Loneliest Whale. Why, despite 20 years of tracking this thing in sound recordings, do we not have any direct observation of the Loneliest Whale?
She's got the answers. Read the rest

A man from Morecambe believes his dog has found a rare piece of whale vomit while walking on the beach. ... Mr Wilman said: "When I picked it up and smelled it I put it back down again and I thought 'urgh'.
While you were eating Thanksgiving turkey, surrounded by loving family and friends, one whale was all alone, swimming through the Pacific Ocean with no one to talk to and no one to care.
Since 1989, researchers have been tracking this specific whale based on its distinct vocalizations. Baleen whales — a category of cetaceans without teeth, separate from their toothy dolphin/beluga/orca relations — are famous for producing eerie, underwater songs and scientists think those sounds are probably an extremely important aspect of participation in whale society. Baleen whales lack keen eyesight and sense of smell underwater, so sounds are probably how they recognize one another, help each other navigate, and even find mates. But these vocalizations happen in very specific frequency range — between 10 and 31 hertz, depending on the species. The Christmas Whale, on the other hand, speaks at 52 hertz. Imagine brining a piccolo to a tuba party. That is analogous to the awkward position that the 52-hertz whale is in.
Scientists usually pick up the call of the 52-hertz whale sometime between August and December, as it makes its way through a Cold War-era network of underwater microphones in the North Pacific. Although this whale has apparently survived for many years and seems to have grown and matured during that time (based on its voice deepening slightly), it also appears to exist outside of whale social systems. It travels alone. Nobody answers its high-pitched pleas for love. Every so often, non-scientist humans remember that it exists and write sad stories about it. Read the rest
