2024年11月28日 · Oxygen-deficient zones (ODZs) are regions in the ocean that contain very low concentrations, or even no, dissolved oxygen. Marine life may not be able to survive in ODZs, so how these zones may be affected by the warmer temperatures that climate change will cause is a question of vital importance.

2022年8月17日 · Dissolved oxygen (O 2) is essential for most ocean ecosystems, fuelling organisms’ respiration and facilitating the cycling of carbon and nutrients. Oxygen measurements have been...

2023年6月28日 · ODZs are water masses characterized by low dissolved-oxygen concentrations (generally <5 μmol kg −1) at roughly 200–700 m water depth. They form in regions in which ventilation is slow and...

2017年9月15日 · We show that in both ODZs of the ETP wind forcing associated with ENSO drives changes in ocean circulation that lead to very large variations in WCD through a cascade of amplifying effects involving changes in ODZ structure and export production.

2023年6月28日 · The eastern tropical Pacific is currently an oxygen-deficient zone (ODZ): a region of ocean that has low subsurface oxygen levels and supports little life besides microorganisms. a, Data...

2024年4月1日 · In this study, we examine the sensitivity to remineralization of the equatorial Pacific ODZ (O 2 < 60 μ m ol/kg) in a model; the NASA GISS Ocean Biogeochemical Model (NOBM-G) embedded in the NASA-GISS coupled atmosphere-ocean model. We find that increasing the remineralization rate shoals the ODZ onset …

2024年11月28日 · Analysis of nitrogen isotope ratio in skeletons shows strong decadal oscillations in the size of the world's largest oxygen-deficient zone (ODZ) over the last 80 years. These findings imply that this ODZ is more dynmaic than previously thought and could respond quickly to climage changes in the coming decades, with important cosequences for ...

摘要 海洋缺氧区 (odz) 包括公海和沿海缺氧区以及富氧海盆。 本综述的主要目标是展示涉及脂质组学和基因组学的新方法如何告知我们如何看待 ODZ。 审查分为五个部分。

Dissolved oxygen (O 2) is essential for most ocean ecosystems, fuelling organisms' respiration and facilitating the cycling of carbon and nutrients. Oxygen measurements have been interpreted to indicate that the ocean's oxygen-deficient zones (ODZs) are expanding under global warming 1,2.

2024年1月19日 · In this study, we examine the sensitivity to remineralization of the equatorial Pacific ODZ (O 2 < 60 µmol/kg) in a model; the NASA Ocean Biogeochemical Model (NOBM-G) embedded in the NASA-GISS coupled atmosphere-ocean model. We find that increasing the remineralization rate shoals the ODZ onset depth (i.e. the regionally averaged upper bound ...
