A carbonate corrosion experiment at a marine methane seep: The role of aerobic methanotrophic bacteria
; ;; ; ; ; ; (Geobiology, 2023-02-12)
Methane seeps are typified by the formation of authigenic carbonates, many of which exhibit corrosion surfaces and secondary porosity believed to be caused by microbial carbonate dissolution. Aerobic methane oxidation and ... -
Planktic foraminiferal response to an early Paleocene transient warming event and biostratigraphic implications
; ; ; ; ; (International Journal of Earth Sciences, 2021-02-22)
The Latest Danian Event (LDE, ~ 62.2 Ma) is characterized by global changes in the carbon cycle as indicated by two negative δ13C excursions of up to ~ 1‰. These δ13C shifts are accompanied by a 2–3 °C warming of both ... -
