Abstract. Coastal hypoxia (defined here as Hypoxia alters both the structure and function of benthic communities, but effects may differ with regional hypoxia history. Human-caused hypoxia is generally linked to eutrophication, and occurs adjacent to watersheds with large populations or agricultural activities. Many occurrences are seasonal, within estuaries, fjords or enclosed seas of the North Atlantic and the NW Pacific Oceans. Benthic faunal responses, elicited at oxygen levels below 2 ml L−1, typically involve avoidance or mortality of large species and elevated abundances of enrichment opportunists, sometimes prior to population crashes. Areas of low oxygen persist seasonally or continuously beneath upwelling regions, associated with the upper parts of oxygen minimum zones (SE Pacific, W Africa, N Indian Ocean). These have a distribution largely distinct from eutrophic areas and support a resident fauna that is adapted to survive and reproduce at oxygen concentrations

Tolerance of benthic macrofauna to hypoxia and anoxia in shallow coastal seas: a realistic scenario (2012, background): “This level of detail of mortality extends earlier field observations (e.g. Stachowitsch 1984, Jorgensen 1980) as well as recent reviews (e.g. Levin et al. 2009) and meta-analyses (e.g. Vaquer-Sunyer & Duarte 2008).”
Projected impacts of climate change on marine fish and fisheries (2013, background): “The vulnerability of species to these changes varies considerably (Whitney et al. , 2007; Feely et al. , 2008; Vaquer-Sunyer and Duarte, 2008; Levin et al. , 2009; Ries et al ., 2009; Rabalais et al. , 2010).”
Characteristics of meiofauna in extreme marine ecosystems: a review (2018, background): “The foraminifera species Virgulinella fragilis was recorded in Walvis Bay sediments (Benguela shelf, West Africa), where the sub-thermocline is perennially hypoxic (Tsuchiya et al. 2009; Levin et al. 2009).”
A coupled physical-biological model of the Northern Gulf of Mexico shelf: model description, validation and analysis of phytoplankton variability (2011, background): “, 2002) and is thought to be detrimental to metazoans such as shrimp and demersal fish (Levin et al., 2009; Ekau et al., 2009).”
The Economics of Dead Zones: Causes, Impacts, Policy Challenges, and a Model of the Gulf of Mexico Hypoxic Zone (2014, background): “Our current understanding of the impacts of hypoxic conditions on organisms, populations and communities, and ecosystem function is summarized in several reviews (Diaz and Rosenberg 2008; Levin et al. 2009; Rabalais et al. 2010) and a book (Rabalais and Turner 2001).”
Future ocean acidification will be amplified by hypoxia in coastal habitats (2013, background): “As indicated above, the majority of laboratory experimental work on hypoxia tolerance of marine organisms has been carried out without the simultaneous manipulation of pCO2 (see references discussed in Grieshaber et al. 1994; Gray et al. 2002; Levin et al. 2009).”
Interactive effects of acidification, hypoxia, and thermal stress on growth, respiration, and survival of four North Atlantic bivalves (2018, background): “Individually, each of these processes can affect bi - valves (Weiss et al. 2007, Levin et al. 2009, Talmage & Gobler 2010), but the effects of these stressors may be species- and life stage-dependent (Pörtner 2008).”
Deoxygenation of the Baltic Sea during the last century (2014, background): “Hypoxia directly impacts marine ecosystem function and services through changes in food web structure and biodiversity (25, 26).”
A basin redox transect at the dawn of animal life (2012, background): “…in regions of anthropogenic eutrophication that show deleterious oxygen responses at relatively minor oxygen depletions (Diaz and Rosenberg, 1995; Levin et al., 2009), OMZs have experienced geologically long-lasting dysoxic- to anoxic-conditions, allowing the fauna to adapt to these levels and…”
