Ocean acidification

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

Conference Description: The Second International Indian Ocean Expedition (IIOE-2) was launched in December 2015 at the culmination of the Indian Ocean Conference at Goa to mark the completion of 50 years of first International Indian Ocean Expedition. The IIOE-2 is a multi-national, multi-institutional programme to advance our understanding of the physical, chemical, biological, geological and climatological aspects of the Indian Ocean to enhance its role on the socio-economy of the region.

Abstract submission deadline: 15 October, 2019

Sessions:
01: IIOE-2 contribution to sustainable development: toward the UN Decade of ocean science
02: Impacts of climate change on the Indian Ocean
03: Circulation and Boundary currents in the Indian Ocean
04: Ocean observations and data in the Indian Ocean: toward an ocean data information system
05: Biogeochemistry and Microbiology of the Indian Ocean: Recent advances
06: Ecology of the Indian Ocean: Understanding and Predictability
07: Air-Sea interactions, exchange of trace gases and related processes
08: Atmospheric Chemistry and pollution
09: Coastal and estuarine processes: Anthropogenic impacts and vulnerabilities
10: Climate and monsoon variability: Lessons from paleo-climatic studies and links to polar regions
11: Inter-basin interactions in the Indian Ocean
12: Marginal seas of the Indian Ocean
13: Geology, geophysics and seabed mapping of the Indian Ocean
14: Extreme events and their impacts

Date: Tuesday, September 3, 2019 7:00-9:00 pm CEST

Description: The purpose of this webinar is to share an update on a 6-year effort to build an integrated model of the California Current System and apply it to investigations of ocean acidification and hypoxia, including local anthropogenic inputs and climate change. Panelists will:
provide an update on the status of the modeling system;
share early examples of model applications; and,
discuss how the model investments are already being leveraged to applications beyond acidification and hypoxia.

Panelists:
Jim McWilliams, UCLA Department of Earth and Atmospheric Sciences
Curtis Deutsch, University of Washington School of Oceanography
Fayçal Kessouri, Biogeochemistry Department, Southern California Coastal Water Research Project
Daniele Bianchi, UCLA Department of Earth and Atmospheric Sciences

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.
