A Selected Review of Impacts of Ocean Deoxygenation on Fish and Fisheries
Fishes, 2023 Oxygen is crucial for the survival of marine species. Yet, the ocean has experienced a loss of approximately 2% of its oxygen inventory since the last century, resulting in adverse impacts on marine life and ecosystems.

Deoxygenation of chalcogen oxides EO2 (E = S, Se) with phosphaWittig reagents [PDF]
, 2022 In here we present the deoxygenation of chalcogen oxides EO2 (E = S, Se) with phosphanylidene-σ4-phosphoranes, also referred to as phospha-Wittig reagents.

Contrasting responses of the ocean’s oxygen minimum zones to artificial re-oxygenation
Environmental Research Letters, 2023 Studies assessing potential measures to counteract the marine deoxygenation attributed to anthropogenic activities have been conducted in a few coastal environments and at regional scale, but not yet on a global scale.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 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.

Regional projection of climate warming effects on coastal seas in east China
Environmental Research Letters, 2022 The coastal region in east China experiences massive anthropogenic eutrophication, and the bottom water off the Changjiang River Estuary in the East China Sea faces the threat of severe seasonal hypoxia. We find that projected future climate changes will
