Hello all,

We encourage abstract submissions to our hybrid (online and in-person)
Ocean Sciences Meeting 2022 session.  We are particularly interest in
calcifying ecosystems, including coral reefs, and interacting stressors.
CB12 Coastal Acidification in a Multistressor Ocean

The OSM 2022 abstract submission deadline is 11:59 pm EDT on Wednesday,
September 29th.

The full session description is below and you can find it in the OSM 2022
program with the Coastal and Estuarine Biology and Biogeochemistry sessions
(scroll down to CB12) here
<https://www.aslo.org/osm2022/scientific-sessions/#cb> (

We are very excited for this interdisciplinary session and look forward to
receiving your abstracts!

Ocean acidification refers to the increase in seawater carbon dioxide (CO2)
and accompanying decrease in pH, calcium carbonate saturation state (Ω),
and carbonate ion concentration driven by oceanic uptake of anthropogenic
CO2 from the atmosphere. Ocean acidification, in concert with other climate
change impacts (e.g. warming, deoxygenation, changing current patterns), is
altering the biogeochemical cycling of the global ocean, with numerous
negative impacts on marine organisms, ecosystems, and associated ecosystem
services. In addition to these global stressors, the coastal ocean is
subject to a wide range of local anthropogenic stressors that can
exacerbate or ameliorate acidification of coastal waters. For example,
land-use changes can alter freshwater input, nutrient loading, and
sedimentation, leading to changes in pelagic and benthic production, which
can cause concurrent hypoxia and acidification, and affect seawater CO2,
pH, and Ω. Further, global and local processes interact to affect coastal
acidification in ways that are currently difficult to predict. For example,
changes in precipitation patterns can alter carbon cycling through changes
in freshwater input to the coastal ocean. Increasing tropical storm
intensity and precipitation can enhance delivery of land-based nutrients,
causing changes in biological production. Shifts in large scale wind
patterns may affect stratification, coastal upwelling, and bottom water
acidification. Ocean warming causes coral bleaching events that alter the
metabolism and carbon cycling of coral reef ecosystems. This session
explores the multitude of ways global and local stressors combine to affect
estuarine and coastal carbon cycling and acidification, and the current and
future implications for coastal ocean ecosystems. We welcome observational,
numerical modeling, and experimental laboratory and field studies from all
coastal ocean regions, with particular interest in calcifying ecosystems
and interacting stressors.
