Ocean alkalinity, buffering and biogeochemical processes

JJ Middelburg, K Soetaert, M Hagens - Reviews of Geophysics, 2020 - Wiley Online Library
Alkalinity, the excess of proton acceptors over donors, plays a major role in ocean chemistry,
in buffering and in calcium carbonate precipitation and dissolution. Understanding alkalinity …

Natural and anthropogenic drivers of acidification in large estuaries

WJ Cai, RA Feely, JM Testa, M Li… - Annual Review of …, 2021 - annualreviews.org

ocean biogeochemistry and threatened the health of organisms through a process known as …

Controls on surface water carbonate chemistry along North American ocean margins

WJ Cai, YY Xu, RA Feely, R Wanninkhof… - Nature …, 2020 - nature.com
Syntheses of carbonate chemistry spatial patterns are important for predicting ocean
acidification impacts, but are lacking in coastal oceans. Here, we show that along the North …

Redox reactions and weak buffering capacity lead to acidification in the Chesapeake Bay

WJ Cai, WJ Huang, GW Luther III, D Pierrot, M Li… - Nature …, 2017 - nature.com
The combined effects of anthropogenic and biological CO2 inputs may lead to more rapid
acidification in coastal waters compared to the open ocean. It is less clear, however, how …

Cable bacteria generate a firewall against euxinia in seasonally hypoxic basins

D Seitaj, R Schauer, F Sulu-Gambari… - Proceedings of the …, 2015 - pnas.org
Seasonal oxygen depletion (hypoxia) in coastal bottom waters can lead to the release and
persistence of free sulfide (euxinia), which is highly detrimental to marine life. Although …

Cable bacteria control iron–phosphorus dynamics in sediments of a coastal hypoxic basin

F Sulu-Gambari, D Seitaj, FJR Meysman… - Environmental …, 2016 - ACS Publications
Phosphorus is an essential nutrient for life. The release of phosphorus from sediments is
critical in sustaining phytoplankton growth in many aquatic systems and is pivotal to …

Emergence of summertime hypoxia and concurrent carbonate mineral suppression in the central Bohai Sea, China

W Zhai, H Zhao, J Su, P Liu, Y Li… - Journal of Geophysical …, 2019 - Wiley Online Library
Abstract The Bohai Sea to the west of the North Yellow Sea in the Northwest Pacific is a
semienclosed shallow‐water marginal sea on a critical path of eutrophication and …

Pathways of methane removal in the sediment and water column of a seasonally anoxic eutrophic marine basin

OM Żygadłowska, J Venetz, R Klomp… - Frontiers in Marine …, 2023 - frontiersin.org
Methane (CH4) is a key greenhouse gas. Coastal areas account for a major proportion of
marine CH4 emissions. Eutrophication and associated bottom water hypoxia enhance CH4 …
