Response to Comment on “Calcareous Nannoplankton Response to Surface-Water Acidification Around Oceanic Anoxic Event 1a

open access: yes, 2011
Gibbs et al. question our reconstruction of surface-and deepwater acidification around Oceanic Anoxic Event 1a. We answer their criticisms to better substantiate our arguments and original conclusions.

Surface-water acidification precedes deep-water carbonate dissolution and anoxia during Oceanic Anoxic Event

open access: yes, 2010
The Early Aptian (~120 Ma) Oceanic Anoxic Event (OAE)1a was caused by massive addition of volcanic CO2 to ocean and atmosphere that should have lowered seawater pH.

Progressive increase in organic-matter burial and preservation from the “Weissert” event to the Faraoni event in Umbria-Marche (central Italy) [PDF]

open access: yes, 2018
The Cretaceous experienced several Oceanic Anoxic Events (or OAEs). Anoxia in these events is indicated by deposits of black shales, enriched in organic matter (OM) compared to the layers below and above, strong carbon isotope perturbations, often with a

The upper Valanginian of the Oliva section (Prebetic Zone, Valencia): facies analysis, biostratigraphy, C-isotope stratigraphy and organic geochemistry [PDF]

open access: yes, 2014
The Upper Valanginian stratigraphic section of the sierra de la Oliva (Prebetic, Valencia province) records a significant sedimentary episode which has been named as ”Weissert Event”.This event is characterized by a positive excursion in the δ13C ...

(Table S1) Calcareous nannoplankton morphometric analyses performed of Cismon sediment core samples

open access: yes, 2010
Ocean acidification induced by atmospheric CO2 may be a major threat to marine ecosystems, particularly to calcareous nannoplankton. We show that, during the Aptian (∼120 million years ago) Oceanic Anoxic Event 1a, which resulted from a massive addition ...
