The Impacts of Ocean Acidification on Marine Ecosystems and Reliant Human Communities

Annual Review of Environment and Resources, Journal Year: 2020, Volume and Issue: 45(1), P. 83 - 112

Published: June 25, 2020

Rising atmospheric carbon dioxide (CO2) levels, from fossil fuel combustion and deforestation, along with agriculture land-use practices are causing wholesale increases in seawater CO2 inorganic levels; reductions pH; alterations acid-base chemistry of estuarine, coastal, surface open-ocean waters. On the basis laboratory experiments field studies naturally elevated marine environments, widespread biological impacts human-driven ocean acidification have been posited, ranging changes organism physiology population dynamics to altered communities ecosystems. Acidification, conjunction other climate change–related environmental stresses, particularly under future change further potentially puts at risk many valuable ecosystem services that provides society, such as fisheries, aquaculture, shoreline protection. Thisreview emphasizes both current scientific understanding knowledge gaps, highlighting directions for research recognizing information needs policymakers stakeholders.

Acidification in the U.S. Southeast: Causes, Potential Consequences and the Role of the Southeast Ocean and Coastal Acidification Network

Frontiers in Marine Science, Journal Year: 2020, Volume and Issue: 7

Published: July 10, 2020

Coastal acidification in southeastern U.S. estuaries and coastal waters is influenced by biological activity, run-off from the land, increasing carbon dioxide atmosphere. Acidification can negatively impact resources such as shellfish, finfish, coral reefs, communities that rely on them. Organismal responses for species located Southeast document large negative impacts of acidification, especially larval stages. For example, toxicity pesticides increases under acidified conditions combination low oxygen has profoundly influences genes regulating consumption. In corals, rate calcification decreases with processes wound recovery, reproduction, recruitment are impacted. Minimizing changes global ocean chemistry will ultimately depend reduction emissions, but adaptation to these mitigation local stressors exacerbate be addressed locally. The evolution our knowledge basic understanding problem emergence applied research monitoring, been facilitated development regional Networks (CANs) across United States.

Here we review issues Southeast, including mechanisms their potential communities. We recommend monitoring priorities discuss role advancing changes.

No effect of ocean acidification on growth, photosynthesis, or dissolved organic carbon release by three temperate seaweeds with different dissolved inorganic carbon uptake strategies

ICES Journal of Marine Science, Journal Year: 2023, Volume and Issue: 80(2), P. 272 - 281

Abstract In a future ocean, dissolved organic carbon (DOC) release by seaweed has been considered pathway for that is not incorporated into growth under dioxide (CO2) enrichment/ocean acidification (OA). To understand the influence of OA on DOC release, 21-day experiment compared physiological responses three species, two which operate CO2 concentrating mechanisms (CCMs), Ecklonia radiata (C. Agardh) J. Agardh and Lenormandia marginata (Hooker F. Harvey) one only uses (non-CCM), Plocamium cirrhosum (Turner) M.J. Wynne. These groups (CCM non-CCM) are predicted to respond differently dependent their affinities Ci (defined as + bicarbonate, HCO3−). Future ocean treatment did drive changes physiology—growth, uptake, production, photosynthesis, respiration, pigments, % tissue carbon, nitrogen, C:N ratios—for any regardless uptake method. Our results further showed method rates OA. show no benefit elevated concentrations physiologies species suggest in photosynthetic fixation these seaweeds will increase with concentration.

Abstract Much has been published on the effects of ocean acidification plankton since original Royal Society 2005 report. In addition to direct primary production, it is clear that also profound consequences for biogeochemistry. Furthermore, although can have grazers such as copepods, induces changes in nutritional value phytoplankton which be passed up food chain.
