Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Assessing net community production in a glaciated Alaskan fjord [PDF]

open access: yesBiogeosciences, 2015
The impact of deglaciation in Glacier Bay has been observed to seasonally influence the biogeochemistry of this marine system. The influence from surrounding glaciers, particularly tidewater glaciers, has the potential to affect the efficiency and ...

Ocean Acidification [PDF]

open access: yesMarine Biology Research, 2011
The ocean helps moderate climate change thanks to its considerable capacity to store CO2, through the combined actions of ocean physics, chemistry, and biology. This storage capacity limits the amount of human-released CO2 remaining in the atmosphere. As CO2 reacts with seawater, it generates dramatic changes in carbonate chemistry, including decreases

Lipid Remodeling Reveals the Adaptations of a Marine Diatom to Ocean Acidification

open access: yesFrontiers in Microbiology, 2021
Ocean acidification is recognized as a major anthropogenic perturbation of the modern ocean. While extensive studies have been carried out to explore the short-term physiological responses of phytoplankton to ocean acidification, little is known about ...

Bioindicators of severe ocean acidification are absent from the end-Permian mass extinction

open access: yesScientific Reports, 2022
The role of ocean acidification in the end-Permian mass extinction is highly controversial with conflicting hypotheses relating to its timing and extent.

Ocean Acidification: An Introduction

open access: yesEDIS, 2018
Ocean acidification (OA) generally refers to the ongoing decrease in ocean pH. Ocean acidification is caused primarily by the oceanic uptake of excess carbon dioxide (CO2) from the atmosphere. Other impacts related to climate change (increased sea level

Advancing best practices for assessing trends of ocean acidification time series

open access: yesFrontiers in Marine Science, 2022
Assessing the status of ocean acidification across ocean and coastal waters requires standardized procedures at all levels of data collection, dissemination, and analysis.

Ocean Acidification and the End-Permian Mass Extinction: To What Extent does Evidence Support Hypothesis?

open access: yesGeosciences, 2012
Ocean acidification in modern oceans is linked to rapid increase in atmospheric CO2, raising concern about marine diversity, food security and ecosystem services.

Ocean acidification in the aftermath of the Marinoan glaciation [PDF]

open access: yes, 2014
Boron isotope patterns preserved in cap carbonates deposited in the aftermath of the younger Cryogenian (Marinoan, ca. 635 Ma) glaciation confirm a temporary ocean acidification event on the continental margin of the southern Congo craton, Namibia.
