Changing Biogeochemistry of the Southern Ocean and Its Ecosystem Implications
Frontiers in Marine Science, 2020 The Southern Ocean plays a critical role in regulating global climate as a major sink for atmospheric carbon dioxide (CO2), and in global ocean biogeochemistry by supplying nutrients to the global thermocline, thereby influencing global primary ...

Winter Limnology: How do Hydrodynamics and Biogeochemistry Shape Ecosystems Under Ice?
Journal of Geophysical Research: Biogeosciences, 2021 The ice‐cover period in lakes is increasingly recognized for its distinct combination of physical and biological phenomena and ecological relevance. Knowledge gaps exist where research areas of hydrodynamics, biogeochemistry and biology intersect.

Linkages between geochemistry and microbiology in a proglacial terrain in the High Arctic
Annals of Glaciology, 2018 Proglacial environments are ideal for studying the development of soils through the changes of rocks exposed by glacier retreat to weathering and microbial processes. Carbon (C) and nitrogen (N) contents as well as soil pH and soil elemental compositions

Spatial continuous integration of Phanerozoic global biogeochemistry and climate
Gondwana Research, 2021 It is important to understand how Earth's surface conditions have changed over geological timescales and what has driven these changes. Much of this understanding comes from combining geological and geochemical data with global biogeochemical models, but

Ocean biogeochemistry in the Canadian Earth System Model version 5.0.3: CanESM5 and CanESM5-CanOE
Geoscientific Model Development, 2021 . The ocean biogeochemistry components of the Canadian Earth System Model v. 5 are presented and compared to observations and other models. CanESM5 employs the same biogeochemistry module as CanESM2 whereas CanESM5-CanOE (“Canadian Ocean Ecosystem model”)
