Workshop for teachers: carbonated water – teaching climate science and ocean acidification

A professional development workshop for middle and high school teachers.

Participants in this workshop will:
• Gain knowledge of climate change and ocean acidification in the Pacific Northwest
• Explore sources of local environmental data and work towards incorporating data into inquiry-based science learning experiences;
• Receive materials and activities included in the Ocean Sciences Sequence (OSS) curriculum on Climate Change developed by UC Berkeley Lawrence Hall of Science
• Become familiar with and utilize Next Generation Science Standards (NGSS) to foster “three dimensional” learning through Cross Cutting Concepts, Core Disciplinary Ideas, and Science and Engineering Practices.

Studying the acidification of Alaska’s waters (video)

Ocean acidification is a looming threat to Alaska fisheries. One of the major concerns is how shellfish may be harmed as the ocean grows more acidic due to climate change.

To further the scientific community’s understanding of how ocean acidification affects bivalves, Alaska Sea Grant funded Amanda Kelley, a leading expert in ocean acidification and a researcher at the University of Alaska College of Fisheries and Ocean Sciences, to conduct an experiment on littleneck clams and basket cockles. She is also conducting nearshore-monitoring of ocean acidification in Kachemak Bay in a collaboration with NOAA’s Kasitsna Bay Lab.

Alaska Sea Grant created this video to convey some of the professional and citizen-scientist work that is being done in Alaska to better understand ocean acidification and its effects on marine life.

Understanding the effects of ocean acidification on shellfish and other species is part of Alaska Sea Grant’s mission to support healthy coastal resources, communities and economies in Alaska.

Carbon dioxide, shell building, and ocean acidification

To build shells and skeletons, marine organisms, such as this hypothetical clam, extract calcium ions and carbonate ions from seawater, combining them into solid crystals of calcium carbonate that are laid down to make shells.

Podcast: Acidificação dos oceanos (in Portuguese)

In this twenty-eighth episode the topic is the increasing acidification (or lowering of pH) of the oceans and the impacts that acidification will have on marine life and the future of the planet.

PhD opportunity: ocean acidification reduction through effective port policies

Location: University of Tasmania, Australia

Closing Date: 11th August 2019

Description: Ocean acidification is a process whereby carbon dioxide (CO2), mainly from the atmosphere, dissolves in seawater and form carbonic acid. This weak acid triggers changes in the seawater chemistry that lead to the decrease of ocean’s pH. It is estimated that oceans absorb about 30% per cent of CO2 produced by humans. As such, CO2 emissions reduction is probably the only sustainable way to minimise this acidification process. However, the present trend of CO2 release to atmosphere does not support this effort. According to the Third IMO Green House Gas Study 2014, the mid‐range forecasted scenarios project a potential increase of CO2 emissions from international shipping between 50% to 250% by year 2050. The magnitude of this increment depends on the aggressiveness of world economic growth as well as energy developments.

In line with the effort of Goal 14 (Life Below Water) of the 2030 Agenda for Sustainable Development, target 14.3 to “Minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels”, the goal of this research is to establish potential port policy that can effectively contribute to the reduction of carbon dioxide emissions from maritime activities within port limits through efficient port operations.
