New Webinar Series


The California Current Acidification Network (C-CAN) is delighted to announce a new series of educational webinars in 2018.  Co-sponsored by NOAA’s Ocean Acidification Program and Northwest Fisheries Science Center, we have scheduled the series to run at 1 PM Pacific Standard Time (4 PM Eastern) on the 8th day of each month beginning in January 2018.

Please join us for our first C-CAN Roundtable discussion of this series on Monday, January 8 2018 at 1pm PST (4pm EST)

Forecasting pH and aragonite saturation state in the Pacific Northwest: progress and needs

Join Drs. Parker MacCready, University of Washington, and Samantha Siedlecki, University of Connecticut, the scientists who have created these models, to learn about these two forecast systems. Joe Schumacker, Quinault Indian Nation, will also share his perspective on the needs and utility of such tools. As noted above, this webinar is co-sponsored by C-CAN and NOAA Ocean Acidification Program and Northwest Fisheries Science Center, with assistance from Dr. Shallin Busch. The host for this presentation is Dr. Jan Newton, Washington Ocean Acidification Center and NANOOS.

Abstract: Ocean acidification of coastal waters is of increasing concern to local fisheries in the Pacific Northwest. This area enjoys a bountiful marine ecosystem that has supported coastal tribes, fishing communities, and a $100 million shellfish industry. The ability to forecast acidification conditions and, further, to develop useful tools for visualization and indices of impact can provide considerable benefit to diverse stakeholders. Implementation of biogeochemical tracers into high-resolution models provides regional simulations that can improve our understanding of processes difficult to observe, investigate relationships between the ecology of marine organisms and ocean health, and generate forecasts and projections of changes to the region. Two such forecast systems now exist on the Washington and Oregon coasts. First, LiveOcean is supported by the Washington Ocean Acidification Center and provides a three-day forecast through the NANOOS portal. For decisions farther out into the future, seasonal forecasting is possible in the region with JISAO’s Seasonal Coastal Ocean Prediction of the Ecosystem, J-SCOPE, (Siedlecki et al, 2016) through the support of NOAA. Results indicate JSCOPE forecasts have measurable skill on seasonal timescales, for variables relevant to management decisions for fisheries, protected species, and ecosystem health. Skill assessment and quantification of model performance for both forecasts systems focus on key variables of interest for local shellfish species: examples include bottom oxygen for adult crab and Ω for oyster and crab larvae. Work now includes implementing a forecast specifically targeting key shellfish species in the region. We plan to showcase our initial results of these pH forecasts and targeted products, including their forecast skill, and discuss the needs of this kind of tool in the region through the eyes of the tribal users from the Quinault Indian Nation.

The Fine Print: Important Notes for participating in the Webinar

1. Plan to log into the Webinar at least 5 minutes before the scheduled start time. GoToWebinar is continually upgrading their software. We want to be sure that your computer has time to access any upgrades and you are able to access the presentation and meeting.
2. When using the VOIP option for this Webinar, you must use a headset or ear bud-speakers. This will keep your output audio from re-entering your microphone, causing distortion
