Ocean heat waves increasing

This is a map showing a huge pool of warm surface water that formed in the North Pacific Ocean from 2013-2015. This pool of warm water was so stagnant that many weather scientists and forecasters casually started referring to it as “The Blob”, and it took the monster 2016 El Niño event to force the extra warm water to disperse. This huge pool of warm water likely contributed to some of the extreme weather events that hit North America in that timespan, as there was nothing like it in the North Pacific Ocean in the available weather records. Although this event was unprecedented in this location, newly available science shows that this type of event is happening with increasing frequency around the world as a result of the warming triggered by human release of greenhouse gases.

Darwin is most famous for his theory of evolution. But did you know that much of his life’s work was influenced by his time at sea? 

In the spirit of Darwin Day, here is one of his observations of bioluminescent plankton while aboard the HMS Beagle on October 24, 1832:

“The night was pitch dark, with a fresh breeze. — The sea from its extreme luminousness presented a wonderful & most beautiful appearance; every part of the water, which by day is seen as foam, glowed with a pale light. The vessel drove before her bows two billows of liquid phosphorus, & in her wake was a milky train. — As far as the eye reached, the crest of every wave was bright; & from the reflected light, the sky just above the horizon was not so utterly dark as the rest of the Heavens.” Charles Darwin

Pyrosome passing through #ClearAPathPeople⁠

Pyrosomes are colonial tunicates made up of thousands of individuals known as zooids. Each zooid is housed in the common gelatinous tunic that makes up the larger cylindrical “body” of the pyrosome. Zooids filter phytoplankton through branchial baskets by creating feeding currents through the tunic. Although each zooid is only a couple of millimeters in size, pyrosomes can reach up to several meters in length. While alive, these organisms spend the majority of their time in the upper water column, but their remains have been found as deep as 4,000 meters (13,120 feet), where they provide food for a variety of deep-sea animals. ⁠ ⁠

Pyrosomes are bioluminescent, producing brilliant blue-green light. Each zooid can detect light and emit light in response, creating waves of bioluminescence up and down the organism’s body. The bioluminescence of one pyrosome can trigger others in surrounding waters, producing beautiful light shows. The name Pyrosoma comes from the Greek term meaning “fire body.”

What if we told you that a group of gelatinous animals helps control the planet’s climate? Your disbelief would be salp-able! 

Salps are filter-feeding gelata related to pyrosomes that pack up plankton produce into poo pellets that precipitate into the deep, capturing carbon from the atmosphere and tucking it away in the depths of the hydrosphere.

Thanks to local photographers Michelle Manson and Joe Platko for the salp selfies! Joe’s photo on top shows a solitary Pegea confoederata ready to birth the same kind of long chain that Michelle found in her lower photo! 

(The pink orbs are the salps’ guts, and these tubular animals are essentially a passing pasta strainer for plankton!)
