We would like to let you know about the launch of new Global Ocean Acidification Observing Network (GOA-ON) Webinar Series. Webinars will take place every 4-6 weeks at a time that is convenient to the speaker and the speaker's primary audience. All webinars will be recorded and shared on the GOA-ON Youtube Channel. The first presentation in the GOA-ON Webinar Series will be shared by Dr. Sam Dupont and Dr. Steve Widdicombe. Their talk is entitled, "Unifying biological field observations to detect and compare ocean acidification impacts across marine species and ecosystems".

The webinar will take place already this Wednesday, January 27, 2021 at 16:00–17:00 CET (UTC +1). Please register here: https://attendee.gotowebinar.com/rt/2927494101675604495 See below for a brief description of the upcoming webinar.

A Biological Working Group was established within GOA-ON to propose an optimal monitoring strategies (frequency and duration) to observe biological rates of change, allowing combining these data at regional and global scales. We will summarize this strategy focusing on rate of change of biological responses that can then be correlated to the rate of change of OA chemistry. Five fundamental traits and their observable indicator factors were identified: calcified organisms and calcification, autotrophs and primary production, heterotrophs and secondary production, biodiversity and community structure, as well as genetic adaptation.
