An international team of geoscientists recently undertook multiple in situ benthic chamber lander experiments to measure abyssal sediment community O2 consumption (SCOC) in the Nauru Ocean Resources Inc. (NORI)-D license area of the Clarion–Clipperton Zone (CCZ) where polymetallic nodules cover extensive areas of seafloor. They consistently found that more O2 was accumulating in the chambers than was being consumed, resulting in net O2 production.

A recent study has stirred up the debate on when the Central American Seaway closed, a pivotal event that altered oceanic circulation between the Pacific and Atlantic and connected the Americas. Traditionally thought to have closed around 3 million years ago in the Pliocene, new evidence suggests the Panamá Arc might have collided with South America much earlier, during the Middle Miocene (15-13 million years ago). An international research team conducted a comprehensive analysis of three stratigraphic transects across the Uramita suture zone and revealed lower offshore to slope conditions in the seaway from 16.4 to 15.1 million years ago. This supports the Middle Miocene closure theory, although deeper parts of the seaway likely persisted in western Colombia, complicating the story.

People are flocking to Paris for the 2024 Summer Olympics (XXXIII Olympiad). The City of Light has been a cultural, historic, and scientific draw for centuries. Read “Exhibiting life history at the Paris Muséum d’Histoire Naturelle (nineteenth–twenty-first centuries)” from GSA Special Paper 535 “Museums at the Forefront of the History and Philosophy of Geology: History Made, History in the Making.” https://lnkd.in/giinPCy6 In this paper, Claudine Cohen analyzes “how the organization of buildings and collections within the Paris National Museum of Natural History (MNHN), and their successive transformations up to the present, have reflected concepts and controversies over [the] history [of life].” Interested in this sort of topic?
