M #AntarcticPeninsula, known as O'Higgins Land in Chile and Tierra de San Martin in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland #Antarctica.

#Antarctic ‘greening’ at dramatic rate

#Vegetation cover across the #AntarcticPeninsula has increased more than tenfold over the last four decades, new research shows.

#Antarctic greening at dramatic rate, satellite data show https://phys.org/news/2024-10-antarctic-greening-satellite.html paper: https://www.nature.com/articles/s41561-024-01564-5

"Vegetation cover across the #AntarcticPeninsula has increased more than 10-fold over the last four decades... greening trend accelerated by over 30% in recent years... The landscape is still almost entirely dominated by snow, ice and rock, with only a tiny fraction colonized by plant life... But that tiny fraction has grown dramatically"

"In the frigid waters surrounding #Antarctica, an unusual seasonal cycle occurs. As #seawater freezes it rejects salts, creating pockets of extra-salty #brine where #microbes live in winter. In summer, the sea ice melts, producing warmer, fresher water at the surface."

in the relatively short amount of time that’s left between now and 2030,” says Bransome.

The three proposed areas — in #EastAntarctic, the #WeddellSea and the #AntarcticPeninsula — would not just help krill but conserve habitat and protect biodiversity for a huge range of the region’s species.

“Adélie and chinstrap #penguins get almost all of their calories from krill,” says Bransome. “Other predators that would benefit include #CrabeaterSeals, #FurSeals, #GentooPenguins, and #whales,

These #shrimp -like #crustaceans occur around #Antarctica but are most highly concentrated in the #AntarcticPeninsula, which also happens to be one of the fast-warming places on the planet. That’s bad news for krill — and everything that depends on them — which is a lot.

Only a few inches long, Antarctic krill (Euphausia superba) may be small, but their contributions to the #ecosystem are massive — much like the swarms themselves.

Great new paper by Dominic Hodgson and Tom Jordan from #BAS.

Using #Lidar, #Radar & #AirbornePhotography data, they identify the rapid drainage and slow refilling of a ~46m subglacial lake on the #AntarcticPeninsula.

Such findings have implications for the connectivity of the surface and #Subglacial hydrological networks, and, the authors hypothesise, the thermal regime of the #Ice.

Figure 2 from Hodgson, Jordan et al. (2022). This figure consists of 4 oblique aerial photographs showing the surface of the collapsed lake, taken in 2011 and 2018. Ice cliffs about 25m high are evident around the lake, which is approximately 250m in diameter. Also visible are surface meltwater streams, crevasses, and a drainage conduit, as well as Mount Phoebe, the Northern Phobos Ridge, and the Mars Glacier in the background of the images.

Figure 8 of Hodgson, Jordan et al. (2022). A scatter plot of the elevation of the collapsed lake floor on the y-axis over time on the x-axis, from January 2013 until December 2019. The floor elevation has increased approximately linearly at a rate of 3.18m per year. Data is taken from REMA for the four points before 2017, and from LIDAR for the four observations in December 2019, when the rate increased.

🏳️‍🌈🇦🇶🏳️‍🌈 4/5 ...are as much a part of, and a significant builder of, Antarctican culture as anyone else has been over time. And that way - the way we are building our lives in the Antarctica I love - is resolution to be part of a world that's getting better, as the people we individually choose to be in this world.

🏳️‍🌈🇦🇶🏳️‍🌈 3/5 There are no original people of Antarctica. There is no one here who really can make much of an argument that some people "belong" here more than other people. In fact, those of us working on this continent now, some of us for decades, from all over the globe...

🏳️‍🌈🇦🇶🏳️‍🌈 2/5 We are pretty new creatures in Antarctica, as humans - our record here is so recent. A few sightings, but more frequent, documented human contact to this continent is only a century - a bit more. My point is, the human historical record here is in its infancy.

Checking in with some scenes from the Antarctic Peninsula this week. It's been stormy and busy, and, as always, beautiful. The R/V Nathaniel B. Palmer has arrived with more scientists and contract workers (like me). My penguin researcher friends are here, more water sampling grantees, and a fresh catch of #Krill, long-studied here. 🇦🇶🇦🇶🇦🇶 #Antarctica #AntarcticPeninsula #PalmerStation #ThisPalmerLife #ThisAntarcticLife this is not the #SouthPole #Antartida #Antarctique #AntarcticaMastodon

#Introduction Hello Mastodon! I've spent the last day looking around and I like what I see, so thanks #fediverse for what you've built, and the warm welcome to new folks like me.

Who am I? I am no one. Just someone who's been lucky enough to work in #Antarctica for 16 years, and is back for another summer season, this time on the #antarcticpeninsula .

I am employed here, but don't represent anyone but me. I'm proud to work in Antarctica, and happy to share with you. Not a #twittermigration .

Here are a few of my favorite things I've seen so far this Antarctica season, including our research vessel's 4- day trip across the Drake Passage and down the Antarctic Peninsula. I work at one of three US science bases, and this is my 16th season on the ice. Here all summer, and just getting to know the platform.
