Integrating ocean acidification into coastal benthic ecology

Thursday, February 14, 2019 – 11:00am – 12:00pm

Event Location Schmidt Conference Center

Speaker: Alex Lowe, Smithsonian Environmental Research Center

Pre-registration Required No

Description: Ocean acidification from rising atmospheric CO2 poses serious threats to coastal ecosystem services. Seawater pH can impact physiological processes of many aquatic organisms, including valuable aquaculture species like Pacific oysters. Yet increasingly, researchers are finding that local ecological processes may be altering some of these global trends.

Ecologists have started to realize that that not only does pH affect organisms, but that organisms also affect pH. This discovery is changing the way we view coastal ecosystems. Understanding 1) how environmental factors or ecological processes drive variation in seawater pH; 2) whether this results in spatial variation of long-term ocean acidification; and 3) the effects of this pH variation on coastal organisms are critical research needs for climate change adaptation and management of important natural resources.

In this talk, Alex Lowe will discuss research that explores these questions at different scales in the Salish Sea, Washington, where scientists found that biological processes were the key driver of pH variation at daily, seasonal and decadal scales. In this system, seawater pH changed with phytoplankton and suspended detritus composition, seagrass cover and, to a lesser extent, temperature and salinity. Using experiments with native and aquaculture oysters as examples, Lowe will discuss the potential for integrating observations of carbonate chemistry into coastal ecological studies.

Ocean acidification, climate change, and you: a Casco Bay matters event

Event organizer: Jeff Fetterer

Event Date & Time: March 25, 2019 5:30 pm until March 25, 2019 6:30 pm

Contact email:

For more information:

Location: Southern Maine Community College, Fort Road, South Portland, ME, USA

We are seeing the impacts of climate change in our coastal waters. Friends of Casco Bay invites you to “Ocean Acidification, Climate Change, and You,” three community events. Staff scientist Mike Doan will talk about the warning signs we see in our monitoring data. Casco Baykeeper Ivy Frignoca will inspire the audience to help us respond to these threats to Maine’s coastal environment and marine economy. Learn more.

This is such an important issue that we will offer this presentation at three locations around the Bay in the coming weeks. Come to the event nearest to you, or all three! Free and open to the public.

Webinar: Community of Ocean Action on Ocean Acidification

Time: Tuesday 5 February at 16h00 Eastern Time (ET)

Description: The second webinar of the Community of Ocean Action on Ocean Acidification will take place on Tuesday 5 February at 16h00 Eastern Time. Jessie Turner, OA Alliance Coordinator, will present the International Alliance to Combat Ocean Acidification (VC15195). The presentation will be followed by a discussion about opportunities for the COA on OA to work together to advance progress on SDG 14.3.

Webinar: National marine sanctuaries webinar weries: learn how ocean acidification could affect Dungeness crab

Time: Thu, Oct 18, 2018 12:00 AM – 1:00 AM CEST

DescriptionWhat is ocean acidification? And how could it affect the future of Dungeness crab, one of our favorite seafoods? Join us as we walk through a new educational toolkit to equip you for teaching others about what ocean acidification could mean for the ​Dungeness crab, how this is currently being investigated, and resources to get more involved.

OA Alliance Event at the Global Climate Action Summit

Time:  8:00 am – 10:30 am, breakfast buffet served at 7:30 am

Location:  Aquarium of the Bay (Pier 39 – Embarcadero and Beach Street), San Francisco, CA, USA

The International Alliance to Combat Ocean Acidification invites subnational, national and civil society leaders who are working to support coastal communities impacted by ocean acidification to come together to discuss actionable steps to address changing ocean conditions. Governments from the local to national levels will share policy solutions they have developed within their regions and across climate agreement frameworks through “OA Action Plans.”  Global Climate Action Summit delegations will also announce their commitment to join the OA Alliance and work toward local to global policy commitments.

SOARCE webinar: Beyond dissolving shells in acid new approaches to teaching ocean acidification

Time: Wed, Sep 19, 2018 12:00 AM – 1:00 AM CEST

Description: During this webinar, Brian Erickson of Oregon State University, will provide insight from a review of 90 + existing ocean acidification teaching resources, pointing out key gaps and highlighting an effectie. He will also introduce a brand new education resource to effectively convey ocean acidification to students.

NECAN industry webinar series: OCA impacts on shellfish hatcheries

Time: Tue, Sep 18, 2018 8:00 PM – 9:00 PM CEST

Presentation Abstracts:

Michael Congrove, Oyster Seed Holdings
In Search of a Solution to the Shellfish Hatchery Water Quality Puzzle
Shellfish aquaculture production has seen a steady rise worldwide for the last 40 years. Integral in this has been the ability to consistently produce vast amounts of shellfish larvae in increasingly sophisticated shellfish hatcheries. The fact that these hatchery’s primary task is culturing a calcifying larval organism, a fraction of a millimeter in ultimate size, make them uniquely susceptible to the effects of ocean acidification and/or coastal acidification. Increasing frequency of unexplained poor larval production has spurred commercial shellfish hatcheries in Virginia to loosely organize around the common goal of better understanding the effects of variable ambient water quality on larval production success. Carbonate chemistry being one, albeit big, piece of the total water quality puzzle. This presentation will explore the water quality puzzle and efforts to solve it, as it pertains to shellfish hatcheries from the perspective of Oyster Seed Holdings, a commercial oyster hatchery located on the western shore of Chesapeake Bay in mesohaline waters.
