Ocean Acidification & Harmful Algal Blooms: Defining a Research Agenda

A virtual workshop August 11-13th, 2020

Hosted by NOAA's National Centers for Coastal Ocean Science and Ocean Acidification Program

During June and July a webinar series set the foundation for the workshop - a recording of all of the presentations can be found below!

Contact elizabeth.turner@noaa.gov with any questions about the workshop or webinars!


This workshop aimed to determine a few tractable OA-HAB research priorities for potential  inclusion in an upcoming RFP during our time together by identifying:  

  • gaps in OA-HAB research; and
  • potential useful research products that incorporate OA-HAB interactions

    Modeling and Forecasting OA and HABs to meet stakeholders needs – Regional Perspectives
    Corrosive, hypoxic, and harmful algal bloom (HAB) events in coastal waters are of increasing
    concern to local fisheries and managers. Many important species around the country in coastal
    waters are currently experiencing or are expected to feel effects of ocean acidification and
    harmful algal blooms, both of which have the potential to affect not only marine species health
    but also human health. HAB and ocean acidification (OA) and hypoxia distributions are often
    patchy in both space and time, such that one area might experience a bloom or low dissolved
    oxygen while a nearby area does not, and these conditions can change over the course of a day at
    a single site. Rapid, timely, and spatially extensive detection and monitoring of HABs is vital for
    public health and safety. Similarly, monitoring and forecasts of corrosive conditions are valuable
    for advising shellfish growers. The collective ability to predict the co-occurrence of the intensity
    of harmful algal blooms, hypoxic and corrosive conditions, as well as the spatial variability of
    these conditions, alongside changes in their duration is of considerable benefit to managers.
    Moreover, modeling work can enable scientists to evaluate triggers and possible synergies
    between ocean acidification and HABs to investigate observationally and in the lab. This
    presentation will include recent advances in modeling and forecasting of across different regions
    in the U.S. Nearly all the coastal regions of the US are developing OA forecasts and these
    systems span many habitats relevant to HABs. In some cases, the systems are used for other
    forecasts including HABs. Along the U.S. West Coast, a mosaic of ocean modeling activities,
    run as quasi-operational systems that provide numerous products pertaining to harmful algal
    blooms, ocean acidification, and hypoxia. Along the U.S. Gulf and East coasts, modeling and
    quasi-operational systems focus on hypoxia and HABs.
