Gift - Tropic of Charlie (Island TF)

The seas conceal many mysteries, and while sailors might not be able to explain them all, here's one I can clear up for you: that strange island you might have seen or heard of, one that's curiously shaped a lot like a deer? Yeah, well, that landmass actually used to be one - in particular, my reindeer sona, Charlie! Now, his bright red nose only lights up whenever the volcano it went on to form starts stirring... This older piece was drawn courtesy of my good buddy @Boteusz, who is also the poor sap seen here who has found himself caught ashore just in time for the aforementioned eruption!

"By testing core samples, an international team of geoscientists and geologists has found evidence that much of what is now West Antarctica was a river delta or estuary 34 to 44 million years ago. Their findings are published in the journal Science Advances."

"In 2017, another team of researchers sought to learn more about the ancient history of West Antarctica by venturing to the Amundsen Sea Embayment, near the area where the ice sheet covering the region flows into the sea. They drilled and collected multiple core samples from several middle and inner shelves. For this new study, the research team conducted an extensive analysis of several of those core samples.

They found sections of sandstone dating back to the middle to late Eocene, approximately 34 to 44 million years ago. They also found that the sandstone revealed evidence of a milder past. Using isotopic analysis and other techniques, the researchers found evidence of an ancient river delta or perhaps an estuary.

The core samples showed that sediment was carried from the mountains to the sea by a large river, perhaps one as large as the modern Rio Grande in the U.S., a finding that showed the region was entirely above sea level.

The research team also found evidence of organic compounds, showing that the region had once hosted freshwater bacteria, and perhaps a wide variety of plants and animals—and it may have had temperatures as high as 19°C during the summer months."
