Ocean Acidification

Please consider submitting your abstract to the OA session (SS84) that will be held during the 2021 Association for the Sciences of Limnology and Oceanography conference, before 12 March 2021. 

The session is entitled ‘Ocean Acidification: trends and effects from local to regional scales‘. It will be co-chaired by colleagues from the OA Med-Hub (Steeve Comeau (France), Abed El Rahman Hassoun (Lebanon), Michele Giani (Italy)), but it is not restricted just to OA Med. scientists. So we are looking to receive abstracts from OA colleagues anywhere.

We are waiting the abstracts’ submissions #ASLO2021 here: https://www.aslo.org/2021-virtual-meeting/session-list/

Students who want to attend the 2021 ASLO Virtual Meeting are strongly encouraged to apply for a student award to help cover the cost of registration! Applications due with abstract submission (closes 12 March 2021).

At the upcoming OA Day of Action to be held in Liberia, OA-Africa is hosting a side event event in partnership withThe Ocean Foundation, the IAEA OA-ICC, Future Earth Coasts, Environmental Protection Agency of Liberia, National Fisheries and Aquaculture Authority, and the Liberia Maritime Authority. The objective of the OA-Africa side event is to promote and facilitate a community of awareness around ocean acidification to communicate, develop, and facilitate international activities on ocean acidification, including science, capacity building, and communication. We find that the work on ocean acidification is better appreciated when scientists, industry practitioners, and policymakers collaborate and speak a common language.

The Ocean Acidification Day of Action will be hosted by the National Fisheries and Aquaculture Authority (NaFAA) and Environmental Protection Agency (EPA) of Liberia in cooperation with the Ocean Acidification International Coordination Center (OA-ICC).

Ocean acidification often referred to as “the other CO₂ problem”, is a perturbation of ocean chemistry as a consequence of human CO₂ emission. It has been shown to be a major threat to marine ecosystems worldwide, and is the focus of the UN Sustainable Development Goal (SDG) 14.3. Since 2015, African scientists are actively collaborating to address this issue by advancing ocean acidification research throughout the continent as part of the OA-Africa network.

The 5th International Symposium on the Ocean in a High-CO2 World, 7-10 September 2020 in Lima, Peru, is expected to attract more than 500 scientists in the field. It will maintain the traditional focus of the four previous symposia and will look at ocean acidification and the associated impacts on marine organisms, ecosystems, and biogeochemical cycles, as well as the implications for society. Ocean acidification will be considered in combination with other global changes, such as ocean warming and deoxygenation. More information on the programme can be found on the Symposium website (http://www.highco2-lima.org/).

The IAEA’s Ocean Acidification International Coordination Centre (http://www.iaea.org/ocean-acidification) will support the attendance of selected participants from eligible Member States to present their work and foster international collaboration.

Deadline for nominations through competent official authorities: 6 March 2020

GCAN Webinar Series Presents: Dr. Xinping Hu & Dr. Leticia Barbero

Date: August 21st @ 1:00pm EST

Description: A five-year (2013-2018) time-series of the carbonate chemistry data (pCO2, pH, and carbonate saturation state) collected in surface waters at the Flower Garden Banks National Marine Sanctuary in the northwestern Gulf of Mexico (nwGOM) revealed variable temporal trends. pC O2 and pH showed significant positive (dpC O 2/dt = 5.0±1.1 μatm yr-1) and negative trends (dpH/dt = – 0.0040±0.0010 yr-1), respectively. Both trends were significantly greater than those observed in the open ocean. However, carbonate saturation states with respect to aragonite (Ωarag) did not exhibit statistically significant changes. The difference between these trends (or the lack of) may be partially due to the increase in sea surface temperature (0.25±0.09˚C yr-1), in addition to CO2 induced ocean acidification. In contrast,
significant decadal acidification (ΔpH ~ -0.1) in the subsurface waters (~50-250 m) w as observed in the broader nwGOM based on three separate cruises (2007, 2016, and 2017). Substantial accumulation of respirational CO2 along with atmospheric CO2 uptake may have both contributed to this acidification, but with many unknowns. We will discuss an upcoming project funded by the NOAA’s Ocean Acidification Program (OAP) that targets the ocean acidification problem in the nwGOM.

A Changing Arctic
June 2-5, 2020
Clarion Hotel The Edge, Tromsø, Norway

Description:
Robust evidence now exists for anthropogenically-forced shifts in the Earth’s environment. Observations in the Arctic reveal dramatic reductions in the extent and thickness of the sea ice, rising atmospheric temperatures, widespread permafrost degradation and ocean acidification. These changes bring with them implications for biology, ecosystem services and society in general.
Full understanding of current and projected Arctic environmental change is becoming an imperative in order to minimize and manage corresponding impacts. This conference aims to provide a forum for the three main themes of:

Land – incorporating ecological impacts, permafrost, and landscape evolution
Ocean (coastal and open) – incorporating physical changes, ocean acidification, and ecological impacts
The Future — covering social aspects and including mitigation, adaptation, exploration, and management

The 36th International Geological Congress will be held on 2-8 March 2020 in Delhi, India, and will include a session on ocean acidification under the theme “Oceans in a Changing World”.

Session name: Response of Marine Organisms to Ocean Acidification

Session description: Over the last century, extensive anthropogenic activities on earth led to an unprecedented increase in the atmospheric CO2 concentration and thus warming our climate. The surface oceans absorb a substantial part of the anthropogenically emitted CO2 and increased accumulation of CO2 in the surface ocean waters is increasing H+ and bicarbonate ion (HCO3-1) concentrations, coupled with decreasing pH [acidification (OA)] and carbonate ion (CO3-2) concentrations. The major shift in dissolved inorganic carbon speciation in surface seawater is affecting calcium carbonate saturation state, which is vital for numerous marine calcifying organisms. There have also been examples of resilient species under low pH condition. Autotrophic organism, like phytoplankton may respond differently to this ocean changes since increasing CO2 may be beneficial to them as a substrate for photosynthesis. Our oceans also experiencing warming and hence, under collective (multi-) stress may become deleterious for marine biota. Further, ocean warming is resulting in major changes in ocean physics which may further change nutrient availability and light penetration. These may have potential to impact the entire food chain, fisheries resources and carbon cycling. This symposium intends to include field and laboratory studies on extent of ocean acidification and its impact on marine ecology, with particular emphasis on Indian waters.
