Here are some of the latest happenings in the world of ocean acidification in Canada and beyond!
Call for Abstracts - CB12 Coastal Acidification in a Multistressor Ocean
*Cross posted from the OA Info Exchange (link here).
““Edit: This session is now in the hybrid format and the abstract deadline has been updated below.
The OSM 2022 abstract submission deadline is 11:59 pm EDT on 29 September 2021.
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!
CB12 Coastal Acidification in a Multistressor Ocean
Session Format: In-person
Organizers (find more contact info on the OAIE post here):
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.”
Implementing UN SDG 14.3 Panel Recording
Protecting Communities and Livelihoods from the Threat of a Changing Ocean
Co Hosted by the International Alliance to Combat Ocean Acidification (OA Alliance) and The Ocean Foundation, this panel was held as part of World Oceans Day 2021 on June 8th. The recording is ~1 hour long and features several expert talks from panelists around the world.

Save the Date – OA Week (September 13 – 17, 2021)
Cross posted from the OA Info Exchange:
“Ocean Acidification Week will be back in 2021!
Last September, GOA-ON launched OA Week as a response to the postponement of conferences and events due to the COVID-19 Pandemic. We received such positive responses that GOA-ON, in partnership with NOAA OAP, IAEA OA-ICC, and IOC-UNESCO, is bringing OA Week back this year. We will bring you even more information and sessions from the regional hubs, more presentations by plenary speakers, and more conversations about global ocean acidification research. Please visit the new OA Week 2021 webpage for more details on the event. This webpage will be updated regularly as we continue planning the meeting.
We also need your help: please suggest topics for the Community Discussion Sessions. Think of Community Discussion Sessions as short workshops, listening sessions, interactive presentations, or other platforms for promoting conversations about issues that are relevant to the OA community. Even if you cannot commit to leading a session, we'd still like your thoughts on what topics you'd like to see covered during OA Week 2021. Share your suggestions by commenting on the post on the OA Info Exchange.
Finally, please share this news with your professional networks, and most importantly, don't forget to save the dates: Monday 13 September - Friday 17 September, 2021! If you have other questions about OA Week 2021, please contact us at firstname.lastname@example.org.”
