Thursday May 9, 2019. 12:00 PM. Webinar: An update to the Gulf of Maine Harmful Algal Bloom (Alexandrium catenella) Forecast System. Yizhen Li, CSS/NOAA. Sponsored by NOAA. More information.

The repetitive Alexandrium catenella bloom causes extensive shellfish closure in New England coastal states each spring and summer. An interesting part of its life cycle is the dormant cyst stage to overwinter, the abundance of which has been found to be crucial to the bloom severity for the upcoming season. Improved understanding of the Alexandrium dynamics enables a quasi-operational forecast system transitioning to operations. Here we briefly introduce the research background of the bloom in the Gulf of Maine, followed by an update on the numerical modeling system. We will present the NCCOS efforts in the cyst cruise, the latest water mass characteristic in the Gulf of Maine, and the architecture of the coupled physical-biological modeling system, and coordinated effort to collaborate with other line offices to transition the system into operations. 

About the Speaker: 

Yizhen Li is an oceanographer at NCCOS HAB Forecasting branch, and an adjunct scientist at Woods Hole Oceanographic Institution. Yizhen got his Ph.D. from North Carolina State University, and was a postdoctoral scholar at Woods Hole Oceanographic Institution during 2014-2016. His research interests include: ocean circulation dynamics, mesoscale eddies, ocean data assimilation, coupled physical-biological interactions (HAB in specific). His is leading the project to transition Gulf of Maine HAB forecast system into operations, and engaged in research of HAB related questions in other areas. Working closely with Dr. Richard Stumpf, his recent research focuses on utilizing satellite images and in-situ observations to study the upper ocean processes associated with Karenia brevis bloom in southwest Florida.
