&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;[https://www.cambridge.org/core/books/climate-change-2021-the-physical-science-basis/annex-vii-glossary/058768DADC00B52E2ED3381D0259B4E0 Climate Change 2021 – The Physical Science Basis, Annex VII: Glossary], written by the Intergovernmental Panel on Climate Change (IPCC) and published by Cambridge University Press in 2023, defines hypoxic as: ‘Conditions of low dissolved oxygen in shallow water ocean and freshwater environments. There is no universal threshold for hypoxia. A value around 60 μmol kg–1 has commonly been used for some estuarine systems, although this does not necessarily directly translate into biological impacts. Anoxic conditions occur where there is no oxygen present at all.&lt;br /&gt;
