Description: Oxygen is fundamental for life in the ocean. Low oxygen environments occur naturally in some habitats, including oxygen minimum zones, deep basins of semi-enclosed seas or coastal lagoons and coastal upwelling regions. They are often associated with highly productive surface waters, where input of nutrients via upwelling, riverine or atmospheric supply fuels production of organic matter, part of which is subsequently respired and thereby consumes oxygen. The spatial extent and the severity of low oxygen con

"The Ordovician-Silurian transition (OST) is a critical geological interval, during which dramatic climatic, environmental and biological changes occurred. Although expanded euxinic conditions have been regarded as one of the main causes of Late Ordovician mass extinction (LOME), the controls of euxinia remain the topic of debate. In this study, we evaluate the paleosalinity conditions of the inner Yangtze Sea (IYS) during the OST using a combination of paleosalinity proxies (B/Ga, Sr/Ba, and S/TOC). [...]"
