This winter, a survey on OA was circulated to better understand information needs. Results show questions from residents are aligned with those of researchers.

Early winter has been a busy time for ocean acidification outreach in Alaska, where conversations about ocean acidification and engagement between researchers and the public took place in two communities, a school, a statewide conference, and a multi-state expo.

The Kelley Lab at the University of Alaska Fairbanks is looking for a PhD student to study the physiological impacts of increased pCO2 on clam species that are of subsistence importance to Alaska Native communities.

Last week, the Alaska OA Network met with fishermen at the Pacific Marine Expo in Seattle – an annual event in Seattle that draws thousands of fishermen and fishing industry members from across Alaska and the Pacific Northwest.

Listen to this APRN radio story highlighting NOAA researcher Bob Foy and his ocean acidification lab in Kodiak.

This month, acclaimed Alaska writer Nancy Lord released her latest book called “pH: A Novel“. Lord and AOOS's Darcy Dugan, the director of the Alaska Ocean Acidification Network, will be giving a joint talk at the UAA Bookstore on October 4.

Check out a succinct chart of how OA impacts calcification, growth, reproduction, and survival of the Alaska species that have been studied so far.

Each spring, moorings in the Bering Sea and Gulf of Alaska are "turned around" to download data and check on sensors. This spring's voyage was a success.

Southeast Alaska Tribal Ocean Research, run by the Sitka Tribe, is addressing both OA and Harmful Algal Blooms (HABS) through active research and community engagement.

We are participating in an AMCC program aimed to provide experience to young fishing leaders through mentorship, professional development and hands-on learning. Come work with the network!

This Washington Post article describes the work of Liqi Chen, Wei Jun Cai, and their collaborators that was recently published in journal Nature Climate Change.

The network now has a new executive committee and five working groups to help advance ocean acidification in Alaska.

The paper by Nina Bednarsek and colleagues, published in Ecological Indicators, examines pteropods as a simple, practical indicators of ocean acidification stress.

An ecosystem-scale assessment of the effects of ocean acidification on US West Coast marine organisms suggests Dungeness crabs will likely suffer as their food sources decline. The decline of Dungeness would have some of the most severe economic effects, according to the research.

This Special Feature invites contributions that provide new insights into multiple stressors, ecological and evolutionary processes, systems-level interactions, and policy responses as they relate to ocean acidification. Contributions that address ocean acidification in the context of global ocean change are especially welcome.

Researchers report that over the next 20-30 years, it is likely that ocean acidification will continue to intensify, especially over the shallow Arctic shelves. The rapid rate of this change is likely to impact ecosystems that are already under pressure from rising temperatures and other climate-related factors.

This year's theme is "Impacts of a Changing Environment on the Dynamics of High-latitude Fish and Fisheries" and encourages OA talks. Submit your abstract by Jan 15 for the May 9-12 event in Anchorage.

This article describes 5 ways the Hakai Institute is tracking ocean acidification in the North Pacific. The Alaska OA Network is involved in several of these efforts, from Burke-O-Lators to a new ferry project.

An interactive kiosk, aimed at communicating the issue of ocean acidification to residents and visitors in Alaska’s coastal communities, is about to move to the Sitka harbor.

The Center for Biological Diversity recently sued the EPA over regulating OA under the Clean Water Act. This article in the Atlantic explains why the EPA doesn't enforce OA.

The community of Sitka, led by the Sitka Tribe and the Sitka Sound Science Center (SSSC), is making a concerted effort to monitor ocean acidification in their backyard. Read about five projects currently underway.

The OceansAlaska site is part of a suite of monitoring systems co-located with hatcheries across the Pacific Northwest, strengthening the partnership between OA research and the shellfish industry.

The International Union for Conservation of Nature (IUCN) recently released a comprehensive review on the impacts of ocean warming on fish stocks and crop yields, more extreme weather events and increased risk from water-borne diseases.

An experiment in the Baltic Sea demonstrated for the first time that ocean acidification and rising water temperatures harms the fatty acid composition of copepods in the natural plankton community. As a consequence, fish might find food of poorer quality. Published in ECO.

News outlets across the state, including the Alaska Dispatch, Alaska Public Media, the Arctic Sounder, and Alaska Fish Radio have picked up the Alaska Ocean Acidification Network.

Join the Alaska OA Network and the Alaska Center for Climate Assessment and Policy for a 1-hour webinar on OA monitoring and biological impacts.

Alaska Public Media produced a radio piece on ocean acidification, highlighting Alaska's susceptibility to OA, and the role of the network in responding to changing waters.

Ocean acidification makes it harder for sea snails to escape from their sea star predators, according to a study from the University of California, Davis.

Research conducted by researchers from the University of Chicago show that California mussel shells from the 1970's are 32% thicker. This Science World Report article links the study.

Last summer, NOAA researchers deployed a new type of autonomous vehicle in Alaska waters to test whether long distance, surface level measurements were possible. Watch a video of how the 'sail drone' works in this Alaska Public Media story.

As Siberian permafrost thaws, crumbling Russian coastlines and big rivers flowing north along eroding banks are dumping vast loads of organic carbon into marine waters there, causing much quicker acidification than had been anticipated.
