A new study shows that volcanism 56 million years ago released more methane than previously thought, and that methane emissions from hydrothermal vents were responsible for global warming about 55 million years ago. The vents were active in very shallow water depth or even above sea level, which would have allowed much larger amounts of methane to enter the atmosphere. #ClimateChange #MethaneEmissions #HydrothermalVents https://www.eurasiareview.com/06082023-past-climate-warming-driven-by-hydrothermal-vents/

#PaperOfTheWeek w11 is Moreau et al. (2023), freshly out in #Nature. For-profit bad, but these authors are real nice people.

TL;DR: so, cool!
Opportunistic field observation of a large #phytoplankton bloom in the #WeddellSea. Checked past satellite images: actually happening nearly every other year. Most likely fed by iron from #HydrothermalVents and/or #microbes, transported by #ocean currents. Happy local #FoodChain, and great #CarbonSink

“Most people don’t think about the bottom of the #ocean. When you look at #maps, the ocean is portrayed as flat blue with very few features, however, this couldn’t be further from what the ocean looks like. Picture huge #mountains, exotic #HydrothermalVents, forests, and features that seem otherworldly, supporting diverse life that is just as alien."
