Upcoming webinar: We’ve got chemistry! Leveraging partnerships and the Ocean Acidification Information Exchange to advance ocean acidification and MPA science

Event Date: Wednesday, September 25 at 1 pm US EDT/10 am US PDT/5 pm UTC

Description: Marine protected areas (MPAs), sanctuaries, and reserves offer refuge to a wide variety of marine species, but can they also protect vulnerable organisms from the effects of ocean acidification (OA) and other climate-related stressors? Increasingly, OA scientists and MPA managers are working together to explore questions of adaptability in marine protected areas to explore this question and sharing their ideas on a dynamic new online platform called the OA Information Exchange (OAIE). In this webinar, we will: 1) provide an orientation to the OAIE to the MPA community and other new users, 2) describe how innovative collaborations between researchers and volunteer scientists are advancing both OA and MPA science in the Oregon Marine Reserves, and 3) provide examples of efforts to document changing ocean conditions and understand potential impacts of ecosystem change in Olympic Coast National Marine Sanctuary, including how the development of a sentinel site for ocean acidification on the Olympic Coast supports OA coordination and collaboration in Washington.

Upcoming webinar: Integrated modeling of OAH: supporting management in the California Current

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

Upcoming webinar: Ocean Acidification in the northwestern Gulf of Mexico

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.

Registration open: A Changing Arctic conference, 2-5 June 2020, Tromso, Norway

The FRAM Centre, Nature Climate Change, and Nature Reviews Earth and Environment are pleased to present

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

Session on ocean acidification, 36th International Geological Congress, 2-8 March 2020, Delhi, India

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.
