Upcoming webinar from the International Alliance to Combat Ocean Acidification: Preparing for Blue Ocean COP25

Time: 25 November 2019, 11:00am Pacific Standard Time

Description: On October 30, Chilean President Sebastian Piñera announced COP25 would not be hosted in Santiago as planned due to ongoing demonstrations and civil discourses in Chile.

Since then, the Spanish government offered to host the conference—in partnership with the government of Chile who will retain the COP25 Presidency.

Please join us for an update on ocean related planning efforts for the Blue Ocean COP25 taking place December 2-13 in Madrid, Spain.

As President of this year’s COP, the government of Chile has been working with national partners and other platforms to ensure that oceans are highlighted and play a central role in discussions and negotiations. The “Blue Ocean COP,” remains a critical milestone for ensuring that findings of the IPCC Special Report on Ocean and Cryosphere are incorporated across the UNFCCC.

The OA Alliance is planning a number of events at the upcoming Blue Ocean COP25 in Madrid. Join us on November 25 and learn more!

Learn about ocean acidification and hypoxia

The Oregon Chapter of the American Cetacean Society is having its monthly speaker series meeting on Saturday, Nov. 16, from 10 a.m. to noon. The meeting will be held at the Newport Public Library, 35 NW Nye St., Newport.

This event, which is free and open to the public, will feature a presentation titled “Ocean Acidification and Hypoxia” by guest speaker Dr. Jim Sumich. There will also be a silent auction held at this meeting.

Sumich serves on the Oregon Coordinating Council on Ocean Acidification and Hypoxia representing the Oregon Ocean Science Trust. He is currently an affiliate faculty member in Oregon State University’s Department of Fisheries and Wildlife.

Ocean acidification teacher workshop

Date: Monday 30 October, 3.30pm-5pm

Venue: Lab-in-a-Box, Wainui Beach School, 56 Wairere Rd, Wainui Beach, Gisborne 4010, New Zealand

Looking for interesting and practical activities for your science classroom that relate to real world problems? This workshop will provide resources to help your students understand our local marine environment and the pressures it faces. The workshop focusses on the impact of climate change and, more specifically, ocean acidification on the marine environment. The session is aimed at secondary teachers (biology, chemistry, general science) and educators with an interest in environmental issues. Some of the activities and experiments outlined in the resource book will be demonstrated. Free copies of “The Ocean of Tomorrow”, an
educational resource unit for secondary schools, will be distributed.

Webinar recording: Community of Ocean Action on Ocean Acidification

The Community of Ocean Action on Ocean Acidification held its fourth webinar on 25 September 2019. The webinar included presentations from Dr Peter Thor from the Swedish Meteorological and Hydrological Institute (SMHI) on Sweden’s plans to address and support SDG14.3, including through a national ocean acidification monitoring programme, and from Dr Dorothee Bakker, University of East Anglia, UK, who presented on the Surface Ocean CO2 Atlas (SOCAT).

The webinar recording can be found here.

Webinar: Gene regulatory response to end-century temperature and pCO2 in post-larval American lobster

When: Wednesday October 9, 2019 at 1:00 PM ET

Presented by Richard Wahle, PhD. and Maura Niemisto of the University of Maine

Anthropogenic carbon released into the atmosphere is driving rapid, concurrent increases in temperature and acidity across the world’s oceans, most prominently in northern latitudes. The geographic range of the iconic American lobster (Homarus americanus) spans a steep thermal gradient and one of the most rapidly warming ocean environments. Understanding the interactive effects of ocean warming and acidification on this species’ vulnerable early life stages is important to predict its response to climate change on a life stage-specific and population level. This study investigated the interactive effects of ocean warming and acidification on the gene expression response of the planktonic post-larval lobster from southern New England. Using a full factorial experimental design, lobsters were raised in ambient and elevated pCO2 concentrations (400 ppm, 1200 ppm) and temperatures (16°C and 19°C). Overall, we identified 1,108 transcripts that were differentially expressed across treatments, several of which were related to stress response and shell formation. When temperature alone was elevated (19°C), larvae downregulated genes related to cuticle development; when pCO2 alone was elevated (1200 ppm), larvae upregulated chitinase as well as genes related to stress response and immune function. The joint effects of end-century stressors (19°C, 1200 ppm) resulted in the upregulation of those same genes, as well as cellulase, and the downregulation of calcified cuticle proteins, and a greater upregulation in genes tied to immune response and functioning. These first results of the impact of varying conditions on larval lobster gene expression suggest the existence of mechanisms to respond to stressors resulting from a rapidly changing environment.

Webinar: pH measurements for acidification studies: what to do with available data and methods

When: 4th October Time: 16:00 (GMT)

Oceanographer with doctoral studies in Coastal Oceanography at the School of Marine Sciences of the Autonomous University of Baja California and postdoctoral fellow at the Scripps Institution of Oceanography in San Diego, California. Dr. Hernandez is a specialist in Carbon Dioxide System in seawater and marine biogeochemistry. His research has focused on studying the role of coastal zones in the carbon cycle, including the effect of ocean acidification (OA) on marine ecosystems and its relationship with other stress factors such as hypoxia, climate change and CO2 flows in coastal regions. Dr Hernández-Ayón is a member of the IMECOCAL (Mexican Research of California Current) scientific committee and of the GOA-ON Executive Council. He is a representative of the Surface Ocean Lower Atmosphere Study (SOLAS) group in Mexico, serves as Coordinator of the Mexican Carbon Program (PMC), and is the Co-Chair of the Latin American Ocean Acidification Studies Network (LAOCA).

1st ICOS OTC pCO2 instrument inter-comparison

When: 24 August – 04 September 2020
Where: Flanders Marine Institute (VLIZ) in Oostende, Belgium

In recent years, new technologies have been evolving with a whole new generation of sensors and instruments measuring pCO2 in both the ocean surface and sub-surface entering the market. These include «classical» equilibrator based systems with new CO2 detectors to membrane based sensors that can be submerged.

The aim of this exercise is:

  • to compare the performance of instruments and sensors that are (or will be) used within the ICOS community over a range of temperatures and pCO2 levels.
  • to engage instrument suppliers and manufacturers to work together with the observational community to reach a high level of standardization in operating pCO2 sensors and instruments.
  • to give answers to the community of choosing the appropriate sensor for their application.
