The Community of Ocean Action on Ocean Acidification held its third webinar on 12 June 2019. Dr Libby Jewett, Director of NOAA’s Ocean Acidification Program and previous co-chair of the Global Ocean Acidification Observing Network, GOA-ON, (VC16542) made a presentation on GOA-ON status, progress and lessons learned.

Published 26 April 2019 Web sites and blogs Leave a CommentThe Community of Ocean Action on Ocean Acidification, led by David Osborn, IAEA Environment Laboratories and Bronte Tilbrook, CSIRO, Australia, and co-chair of GOA-ON, aims to support its members in implementing their ocean acidification-related Voluntary Commitments (VC) by exchanging progress reports, experiences, lessons learned and good practices. There are presently 258 Voluntary Commitments submitted for Sustainable Development Goal 14.3 on ocean acidification. These VCs cover a range of topics including mitigation, capacity building, policy, monitoring, among others.
The COA on OA has held two webinars, highlighting specific VCs and facilitating discussions among members of this community. A recording of the most recent webinar can be found here, and a video presentation by David Osborn providing an overview on this COA can be found here.

Four ocean acidification bills take big bipartisan step toward becoming law
Published 11 April 2019 Media coverage , Web sites and blogs Leave a CommentToday, the House Committee on Science, Space and Technology’s Environment Subcommittee will hold a markup of four bills addressing the impacts of ocean acidification. A markup is an opportunity for all members of a congressional committee to review legislation and “mark” it up with their own thoughts and changes. Here at Ocean Conservancy, we are excited to see these bills take this important step. This legislation has enjoyed broad bipartisan support, and today’s markup will show how leaders on both sides of the aisle recognize the importance of preparing their communities for the impacts of ocean acidification.

Crabby but crabtivating: hermit crabs and ocean acidification

Walking along Tower Beach, you might not realize how many different invertebrates are right below your feet. Giant isopods, small-but-mighty barnacles, common shore crabs, blue mussels, and periwinkle snails.
You pick up what you think is an unsuspecting periwinkle snail, but when you turn the shell over, you find a small bristly claw instead of a slimy muscular foot. You just found a hairy hermit crab!
Otherwise known as Pagurus hirsutiusculus, these hermit crabs are found in intertidal ecosystems from California to Alaska. Fluctuations in conditions, incredible competition and intense predation are just some of the challenges they see on a daily basis in the intertidal zone. It already sounds like these guys have it pretty bad, but there’s more…

New ocean monitoring indicators: ocean acidification (video)
Published 15 March 2019 Education , Web sites and blogs Leave a CommentOcean Monitoring Indicators (OMIs) are free downloadable trends and data sets covering the past quarter of a century. These are key variables used to track the vital health signs of the ocean and changes in line with climate change. Knowing how much heat is stored in the ocean, the pH of the ocean, how fast the sea levels are rising and sea ice is melting, is essential to understanding the current state and changes in the ocean and climate. This information is critical for assessing and confronting oceanic and atmospheric changes associated with global warming and they can be used by scientists, decision-makers, environmental agencies, the general public, and in measuring our responses to environmental directives. The OMIs expand the Copernicus Marine Service portfolio to provide not only ocean data products but also key reference information on the state of the ocean.

You better repeat it: serial ocean acidification experiments on fish early life stages
Published 8 March 2019 Web sites and blogs Leave a CommentTo detect potential effects of acidification on marine organisms, experimenters most commonly use within-experiment replication, but repeating the experiments themselves is rarely done. While the first approach suffices to detect major CO2 effects, other potentially important responses may get detected and robustly quantified only via serial experimentation. A study by Baumann et al. in Biology Letters comprises a meta-analysis of 20 standard CO2 exposure experiments conducted over six years on Atlantic silverside (Menidia menidia) offspring.
The sub-surface automated dual water sampler (SAS) was designed by researchers at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and the University of Miami to help scientists study water chemistry on shallow reef habitats. It was also created to minimize some of the financial hurdles in marine research by serving as a low-cost open-source alternative to existing water samplers. Explore the SAS website, use it to guide you in building and using your own water samplers, embrace the maker movement and improve on our design. If you are a teacher, there are free lesson plans to download that include labs and activities related to science, technology, and engineering. Enjoy this site and please use the SAS to learn about and explore our oceans!
