The Great Whale Conveyer Belt | Nautilus

It's well known that salmon transfer ocean nitrogen from the sea to the forests, to the extent that 30% of the nitrogen in BC forests historically arrives that way.

But the whale transfer of nutrients is a whole other things. Sysco of the Seas!

#Whales move nutrients from Alaska to Hawaii in their urine, supporting tropical ecosystems phys.org/news/2025-03-whales-n

Migrating #BaleenWhales transport high-latitude nutrients to tropical and subtropical ecosystems nature.com/articles/s41467-025

"in oceans across the globe, great whales—including #RightWhales, #GrayWhales, and #humpbacks—transport about 4,000 tons of nitrogen each year to low-nutrient coastal areas in the tropics and subtropics. They also bring more than 45,000 tons of biomass"

In French Polynesia, boom in whale-based tourism sparks concern

> A giant whale stole the show at the Summer Olympic Games, shooting out of the water as athletes competed in women's surfing semi-finals on the French Pacific island of Tahiti last month.

Human harvesting of #krill in the Southern Ocean could threaten the recovery of #whale species that were nearly wiped out by industrial whaling in the 20th century, according to a Sept. 10 study in #NatureCommunications.

The tiny, shrimp-like crustaceans known as krill are the essential food source for #BaleenWhales such as #blues and #humpbacks. To feed, these giant marine mammals take in great gulps of ocean water, filtering krill through bristly mouth structures.

How the World’s Oldest #Humpback #Whale Has Survived Is a Mystery
First spotted in 1972, Old Timer is now a male of at least 53 years, making him “the oldest known #humpbackwhale in the world,” said Dr. Pack, who is also the co-founder and president of The Dolphin Institute.
#OldTimer was spotted last month near Alaska, enduring in the Pacific Ocean while some other #humpbacks have struggled in a changing environment.

Speak up for WHALE-SAFE FISHING GEAR

We've just begun to understand the lives of awe-inspiring ocean dwellers like massive #BlueWhales, singing #humpbacks and ancient leatherback #SeaTurtles. Sadly hundreds of thousands of these creatures suffer or die every year from #entanglement in #FishingGear.

According to NOAA Fisheries, 446 large whales got tangled in commercial fishing gear between 2017 and 2022 — and that's likely just a fraction of the actual number of entanglements.

These #Whales Still Use Their #VocalCords.
Unusual experiments on organs recovered from three carcasses suggest how #baleen whales call out at #sea. #Toothedwhales, like #spermwhales and #dolphins, use their larynges like a cork to seal their airways; they evolved a way to produce sounds in their nasal cavities instead. But #scientists suspected that filter-feeding #baleenwhales, including the musical #humpbacks and huge #bluewhales, still use their voice boxes. nytimes.com/2024/02/21/science

#OceanOptimism: Australia's #humpback populations rebound
abcnews.go.com/International/m #Whales #ConservationOptimism #Conservation

"A #CitizenScience census recorded 5,116 #humpbacks, a 57% annual increase. It's an incredible recovery for #Australia's humpbacks, whose populations crashed in 1961... Starting in 1948, the #USSR ignored restrictions implemented by the International #Whaling Commission and conducted a 30-year campaign of illegal whaling in the rich feeding grounds of the #Antarctic."

I need to get a joke out of my system. For the niche orca enthusiasts:

Which pod of northern resident killer whales sings the most whale songs

OKAY! There’s lots of variety in how Northwesterners refer to our whale neighbors—from nicknames like Hydra to coded strings of letters and numbers like J14. These names & IDs often tell us a lot about the whales, and just as much about our relationships w them. 🐳

Some quotes from this ^^^ piece:

"There is zero evidence that any pre-construction activity on #offshore wind turbines has caused harm to the #humpbacks that migrate to our coastline."

Capt. Paul Eidman summarized it: “I’m seeing more prey for fish and #whales in near shore habitats, and warming waters are changing the distribution of whales and other marine wildlife, leading to increased interactions in one of the busiest shipping channels in the country.”
