The OA CoP will be in Vancouver, Canada for the Fifth International Marine Protected Areas Congress (IMPAC5), a global forum that brings together ocean conservation professionals and high-level officials to inform, inspire and act on marine protected areas. 3-9 February 2023, Vancouver, Canada. More information can be found by clicking the congress logo.

Canada's OA CoP leadership team is assisting in the creation of the GOA-ON ICONEC group. This groups' goal is to create an network of early career ocean professionals (ECOP) with an interest in marine carbon. Everyone who is an ECOP and working with marine carbon is welcome to join! Through creating an international network of peers, ICONEC will mobilize early career knowledge, opportunities, and will organize international ECOP led products that will be created for the wider marine carbon community. ICONEC just launched their new Slack workspace. This workspace is intended to help kickstand ECOP driven projects and provide a space for ECOP's to meet, communicate, and collaborate. Twitter and Instagram If you are interested in joining this group or have any questions send an email to: iconechub@gmail.com or visit their GOA-ON webpage here .

The Methodology for the Sustainable Development Goal (SDG) 14.3.1 Indicator calls for the "Average marine acidity (pH) measured at agreed suite of representative sampling stations", along with the associated data and metadata files, are now available on the newly remodelled GOA-ON Resources web page. http://goa-on.org/resources/sdg_14.3.1_indicator.php The Methodology provides the necessary guidance on how to conduct ocean acidification observations, what to measure and how, providing standard operating procedures and methods approved by the ocean acidification community. It further provides support on what kinds of data to collect, and how to submit, towards the SDG 14.3.1 Indicator to enable the collection and comparison of ocean acidification data worldwide

Today is International Ocean Acidification Day of Action! (Jan. 8th, or 8.1, the pH of our oceans) To raise awareness, we are excited to share our newest resource for Canada's Ocean Acidification community: an interactive map of Canada's OA resources !

We're excited to share a new resource on OA sensors for Canada's OA community! In this MEOPAR 2020 webinar, Ph.D. student, Patrick Duke, provides us with an overview of the currently available equipment and sensors for monitoring ocean acidification, as well as considerations to make when selecting sensor packages for your needs, including instrument accuracy, drift, and cost. The webinar is ~35 minutes long, and is fully captioned. Watch the webinar here! Subscribe to our YouTube channel for more video content!

New webinar recording: OA CoP guest webinar with Krysten Rutherford, Ph.D. Candidate, Dalhousie University (April 14, 2021). Source or Sink? A numerical modeling study of inorganic carbon fluxes on the Scotian Shelf The webinar is ~45 minutes long, and is fully captioned. Watch the webinar here ! Abstract: Continental shelves are thought to be disproportionately affected by climate change and are a large contributor to global air-sea CO2 fluxes. Additionally, it is often reported that low latitude shelves act as net sources of CO2 to the atmosphere whereas mid- and high-latitude shelves act as net sinks of CO2. Here, we focus on the Scotian Shelf, a mid-latitude shelf in the northwest North Atlantic. Whether the Scotian Shelf acts as a source or sink of CO2 is controversial in the literature. Here a high-resolution regional model is employed to explore shelf-wide pCO2 variability and better understand what processes are underlying the regional air-sea CO2 fluxes. Seasonally, surface pCO2 on the Scotian Shelf is strongly tied to the large drawdown in Dissolved Inorganic Carbon (DIC) during the spring bloom, and temperature effects associated with warming from 0oC in winter to nearly 20oC in summer. Spatially, pCO2 on the Scotian Shelf is relatively uniform, except for coastal upwelling events during the summer which lower nearshore pCO2 in the surface water. The model agrees with regional observations and reproduces seasonal patterns of pCO2. On the Scotian Shelf, the model simulates net annual outgassing of CO2 from the ocean, which is in contrast to the global pattern. Passive dye tracers are used to qualitatively diagnose the dominant transport pathways in the model and their effect on CO2 dynamics. This analysis suggests that the Scotian Shelf is highly influenced by cold, DIC-rich Arctic-originating water that is warmed as it travels, thus becoming oversaturated with CO2 and feeding outgassing from the ocean. Speaker bio: Krysten Rutherford was born and raised in Southern Ontario. She did her undergraduate degree in Engineering Chemistry at Queen’s University in Kingston, ON. While there, she spent a couple summers with the Geography Department doing research on High Arctic watersheds. Shortly after graduating from Queen’s, she joined Dr. Katja Fennel’s lab group at Dalhousie University (Halifax, NS) to do her master’s degree in Oceanography. She enjoyed her work so much that after a couple years working on her master’s thesis, she decided to keep working with Dr. Fennel to complete her PhD. This work has focussed on using a biogeochemical model of the northwest North Atlantic to understand the carbon cycling and transport here. She will be defending her PhD within the next few months.

Registration for the upcoming 3-day BC Fisheries & Aquaculture workshop, Nov 2 - Nov 4, 2021 , is now open! This is the first in a series of 4 workshops that will be hosted by the Government of BC, Ministry of Agriculture Food and Fisheries. The goal of the 3-day workshop is to give a cross-section of the state of the science that is being conducted on ocean acidification and hypoxia research in British Columbia. The workshop hopes to identify gaps in knowledge and to develop regional plans and recommendations to aid BC fisheries and aquaculture with adaptation. To effectively achieve a thorough environmental scan, they consider 4 key themes: Observing Modeling Biological impact Mitigation and adaptation These themes will be discussed during the 6 available sessions and question periods. The sessions available at this workshop are as follows: Session 1: OAH Frameworks & Gaps in Our Knowledge Session 2: OAH Observing Session 3: OAH Modeling Session 4: Biological Impacts from OAH Session 5: Mitigation & Adaptation Session 6: Discussion and Concluding Remarks For more information and registration, click here!

OA Day of Action January 8th 2022 OA Day of Action 2022 is here! January 8 is global OA Day of Action, this initiative was started by the Ocean Foundation and is held annually on the date that corresponds to the current pH of the ocean (8.1). It's goal is to raise worldwide awareness for ocean acidification and it's global current and future impacts. Visit their website by clicking here! The ocean foundation helps to promote and develop ocean acidification education resources that will help raise awareness and understanding of this global threat. They both partner with groups creating and create their own Educational Resources every year! To learn more visit the Ocean Foundation's website page for OA day 2022 by clicking here.
