A couple of weeks ago, oceanographers compared the songs of bowhead whales to jazz compositions. They determined that these whales communicate with their relatives by generating fairly complex melodies. Animals are able to change their own "songs" several times during the season. The "songs" of these animals turned out to be more varied than of humpback whales, which repeat the same set of sounds for one season. Let's listen to their songs together on the Shantar Islands!

Пару недель назад океанологи сравнили песни гренландских китов с джазовыми композициями. Они определили, что эти киты общаются со своими родственниками при помощи сложных мелодий. Животные способны менять собственные «песни» несколько раз в течение сезона. «Песни» этих животных оказались более разнообразными, чем у горбатых китов, которые повторяют одинаковый набор звуков на протяжении одного сезона. Будем вместе слушать их песни на Шантарских островах!

The world’s oceans are sweltering. Over the last century, marine heat waves have become more common and are lasting longer. New research suggests the annual number of days that some part of the ocean is experiencing a heat wave has increased 54 percent from 1925 to 2016, researchers report April 10 in Nature Communications.
Typically, scientists define a marine heat wave as at least five consecutive days of unusually high temperatures for a particular ocean region or season. These extreme temperatures can be lethal for marine species such as corals, kelp and oysters, and can wreak havoc on fisheries and aquaculture
In the new study, the researchers searched for such events recorded in sea surface temperature data recorded as far back as 1900 and in satellite data since 1982. Not only have the heat waves become 34 percent more common on average, but they also last an average 17 percent longer, the team found.
That trend is mostly influenced by climate change causing surface ocean waters to warm, rather than by large atmosphere-ocean climate patterns, such as the periodic warming and cooling of waters in the equatorial Pacific called the El Niño-Southern Oscillation. The researchers predict even more frequent marine heat waves in coming decades.

Researchers gathered recordings of bowhead whales from 2010 to 2014 in waters to the east of Greenland. The population of bowhead whales was almost hunted to extinction in the 1600s, and was recently estimated to consist of roughly 200 individuals. Now, these recordings indicate that the population is at healthy levels. “If humpback whale song is like classical music, bowheads are jazz,” says Kate Stafford, an oceanographer at the UW’s Applied Physics Laboratory and lead author of the study. “The sound is more freeform. And when we looked through four winters of acoustic data, not only were there never any song types repeated between years, but each season had a new set of songs.” Learn more at EARTH.COM
Today I’m thinking of adding some more sea creatures to my paper doll collection! A turtle perhaps? A clown fish? A squid? Help me decide what other creatures should join the foray! 💙 You can purchase downloadable paper dolls from my Etsy store: etsy.com/au/shop/MichelleFleurArtist 💙
First, if it is your birthday today: On behalf of the team, I (@mrpocean) am happy to wish you a Happy birthday! 🎂 Cakes on us. Tell us in the comment section.
This week, we will talk about sea organisms with the longest lifespans. 👴👵Organisms that defy death to grow old.

OceanFact: What a better example than to start with the bowhead whale 🐳with a record of 211 years, more or less 35 years. This is twice more than humans. In 2017, a group of researchers started investigate longevity using this whale as their model. They found that despite having 1,000 more cells than humans, their risk of getting cancer is much lower, which implied highly efficient mechanisms were in play. The genome sequencing of the bowhead whale and other long-lived animals will help identify mechanisms maintaining life. Maybe a cure against cancer is on its way.

You might think that only gigantic animals (i.e. whales, elephants) live longer but you will be surprise, this week. You know what to do. Subscribe and stay tuned. Leave a comment and make us happy to do what we do. -----

Bowhead whales son!! The longest-lived mammal and my 2nd favourite whale. Originally thought to have a similar lifespan to humans and other whales, a female bowhead was found in 2007 with an 18th century harpoon still stuck in her side. This lead to further research finding that bowhead whales can live well past 200! Or, born around the same time as the French Revolution. Like Napoleon is an ambitious young officer who sees a baby whale and then that baby whale grows up to see us! Crazy shit.
These whales are large af, newborns weigh 1 ton and then grow 8 metres in a single year, or around an inch a day. The biggest adults can reach 18 metres long and weigh 120 tons. They headbutt sheet ice to get oxygen, able to smash through a metre of it. Hunting led bowhead whales almost to extinction, and today only Inuits can legally hunt them, sustainably as they have for thousands of years. Whales are an important part of arctic tribal culture, represented as powerful spiritual beings. Their blubber is identified as the main reason certain Greenlandic peoples never get heart disease. So yeah, solid whale, good guy, lot of respect.

Oh look, it’s a big bowhead whale! Yep, here’s yet another paper doll I’ve created! I’m having such fun with these! 💙💙💙 You can purchase the template for this beautiful Whaley in my @Etsy downloadable art store. The link is in my profile. 💙💙💙 So, what can you do with these whimsical little paper creations? Well, your imagination is the limit! You can use them as fun bookmarks (and are a nice surprise to find inside a book you haven't picked up for a while!). They make cute cards for a sea loving friend - just write your message on the back. A bunch of paper dolls can be printed out on card, tied together with some twine, and then given as a crafty gift to a whale loving child (put a little envelope of split pins with it so they don't have to go out and purchase them especially). You can make paper buntings out of them, or put them as place cards on an ocean themed table, or pin them up as decorations at a sea themed kids party. The possibilities are endless! 💙🐳💙
We’ve done eyes, we’ve done noses, and now move onto #magnificentmouths ! The largest mouth in the world belongs to the bowhead whale and can measure 5 m (16 ft) long, 4 m (12 ft) high and 2.5 m (8 ft) wide. Its tongue weighs approximately one ton (900 kg). Bowheads are mainly found near the Arctic icepack and feed on planktonic organisms consuming about two tons (1,814 kg) of food every day. As a baleen whale, the bowhead has between 325-360 fringed overlapping plates hanging from each side of the upper jaw, where teeth would normally be found. In fact, the bowhead has the longest baleen of any whale. While feeding, the whale opens its mouth and skims through the water. As the water flows through the mouth and through the baleen, the plankton get trapped inside near the tongue and are then swallowed. That’s one big, plant powered animal!
