Ocean acidification adaptation and resilience in Africa (video)

Coastal communities in many African countries rely heavily on the sea for economic, social, and nutritional services. Ocean acidification has the potential to negatively affect marine ecosystems important to these communities. The losses would be alarming for the African continent. The IAEA is working with local, regional and international partners to understand and undress potential impacts and solutions to ocean acidification in Africa.

Behavioural responses of fish to high CO2/low pH conditions observed at natural analogues (video & text)

Prof Tim Ravasi and Dr Davide Spatafora present their research on how the molecular basis and behavioural adjustments reveal potential local adaptation to acidifying oceans, a lesson from natural analogues, the second webinar from the International CO2 Natural Analogues (ICONA) Network. The first response by animals to a changing environment is predominantly through modification of their behaviour. In this context, investigating behavioural responses of fish living under low-pH/high-CO2 conditions (e.g. off volcanic seep sites) may contribute to a better understanding of how marine species might adjust or adapt to environmental conditions under projected ocean change scenarios. We carried out field-based observations and translocation experiments in the Vulcano island natural CO2 seep (southern Italy) to assess whether there is evidence for local behavioural adaptation and/or acclimatization of fish after long and short-term exposure to ocean acidification conditions predicted to occur by the end of this century. The responses of two temperate fish species, characterized by a limited home range, have been investigated and compared between fish from low-pH/high pCO2 sites and fish from control sites. Furthermore, understanding the molecular underpinnings responsible for acclimatization to acidified waters, by means of an integrated study of the brain transcriptional program of wild fish species, can elucidate on the variation in responses. We collected 130 individuals of six different reef fish species from a natural volcanic CO2 seep and nearby control reefs in Papua New Guinea. Differences in brain gene expression in fish from CO2 seeps compared to fish from control sites as well as differences among species identified the molecular pathways controlling the cellular responses to elevated CO2. These studies provide a broader understanding as to the behavioural and molecular alterations crucial for coping with naturally elevated CO2 conditions.

Two poles, one common future – Richard Bellerby: ocean acidification (video & text)

In a series of short video interviews, the Prince Albert II of Monaco Foundation together with its partners in The Polar Initiative – SCAR, IASC and the Oceanographic Institute of Monaco – invited polar scientists and specialists to give a voice to polar regions, calling for a greater protection of Arctic and Antarctic regions and for shedding a light on the benefit they represent for the Planet and Humanity.

Richard Bellerby, Director SKLEC-NIVA Centre for Marine and Coastal Climate Research, states that “ocean acidification is one of the biggest challenges that we have to date (…), that will cause the local if not total extinction of some crucial species within the ocean.” According to him, “we have get the message out”, to the media and to the general public, as it is happening faster than ever before.

This is CDR ep.49: MRV for ocean-based CDR methods with Dr. Jessica Cross, NOAA (video & text)

In this episode of This Is CDR, OpenAir welcomes NOAA Research Oceanographer Dr. Jessica Cross to discuss the challenges associated with measurement, reporting, and verification (MRV) of ocean-based CDR methods, and how we can seek to address them in a climate-relevant time-frame.

About our Guest. – https://www.pmel.noaa.gov/people/dr-j…

Dr. Jessica N. Cross is a research oceanographer with the NOAA in Seattle, WA. Her current research focuses on carbon biogeochemistry and ocean acidification in Arctic regions, and especially along the Alaskan coast. The main goal is to better understand how acidification processes interact with natural biogeochemical cycles, and eventually to detect geochemical and biological impacts of acidification in marine systems. Dr. Cross conducts her research across a variety of platforms, including ship-based measurements, moorings, and mobile autonomous platforms like gliders and drones, through NOAA’s Innovative Technology for Arctic Exploration Program. She also broadly participates in the Arctic research community through the North American Carbon Program, the Ocean Carbon Biogeochemistry Program, the Pacific Arctic Group, and the Interagency Research Policy Committee collaboration teams.

An interactive planetary boundaries systems thinking learning tool to integrate sustainability into the chemistry curriculum

Sustainability has a molecular basis that suggests a central role for chemistry in addressing today’s challenges to Earth and societal systems, and this role requires educators to see chemical reactions and processes as integral parts of dynamic and interconnected systems. Despite this prospect, few accessible resources are available for students and educators to facilitate systems thinking in chemistry for sustainability. We have developed an interactive digital learning tool (https://planetaryboundaries.kcvs.ca) based on the Planetary Boundaries framework, which uses interactive visualizations to help users better understand Earth system sustainability challenges and helps chemists and educators connect substances, reactions, and chemistry concepts to sustainability science. The tool highlights the fundamental role that chemistry plays in regulating the individual biophysical Earth system processes and in determining their control variables. It incorporates key features of a systems thinking framework by illustrating the dynamic interconnections among the processes and their control variables and demonstrates change of the Earth system over time. Finally, the interactive tool provides educators with accessible entry points to support the integration of chemistry curriculum content with sustainability considerations.

OA action plan toolkit & guide

The International Alliance to Combat Ocean Acidification (OA Alliance) brings together governments and organizations from across the globe dedicated to taking urgent action to protect coastal communities and livelihoods from the threat of ocean acidification and other climate- ocean impacts.

Facilitated through the OA Alliance, national, subnational, regional and tribal governments are proactively responding to the impacts of ocean acidification as they create OA Action Plans to effectively promote solutions and advancing knowledge into action.

The OA Alliance has created this Action Plan Toolkit as a guide. The OA Action Toolkit contains both regulatory and non-regulatory actions that members might consider when crafting their own OA Action. Not all OA Action plans will have the same framework or structure, as there is no “one- size fits all” approach.

Some members may choose to write a stand-alone plan, while others may decide to integrate ocean acidification mitigation, adaptation and resiliency actions across existing Climate Action Plans, Ocean Action Plans, Biodiversity or Resilience Goals and Targets, Nationally Determined Contributions pursuant to the Paris Climate Agreement, or decide to integrate and strengthen actions across other applicable management tools.
