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

A webinar series will set the foundation for the workshop with 1-2  presentations weekly from mid-June to mid-July.

We aim 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

    Drs. Samantha Siedlecki, Clarissa Anderson, Jan Newton and Barb Kirkpatrick discuss  how 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.

    Acidification, eutrophication and HABs in estuarine waters:  What do long-term data tell us?

    Acidification, eutrophication and HABs in estuarine waters: What do long-term data tell us?

    Hans Paerl of University of North Carolina- Chapel Hill discusses how estuaries receive and process nutrient loads generated in coastal watersheds and often exhibit accelerated rates of primary production (eutrophication), phytoplankton blooms, hypoxia and associated water quality and habitat declines. As such, they are highly dynamic with respect CO2 fixation and mineralization of autochthonous organic matter (OM), which modulate pH. Watershed-derived (allochthonous) OM plays an additional role in mediating carbon fluxes and pH. Increasing anthropogenic activities as well as climatic changes (more extreme episodic rainfall events and increasingly variable wet/dry cycles) impact nutrient and inorganic/organic carbon loading to estuaries.

    Synergies Between OAH and HAB Networks: California as a Case Study

    Raphe Kudela of University of California Santa Cruz shares how the US west coast is experiencing increasing environmental stress, as are all coastal regions globally. Unlike some other regions, eastern boundary currents naturally experience large swings in pH and decadal oscillations in temperature, making the west coast an ideal location for observing the interactive effects of multiple stressors as a precursor to our future ocean. California has been proactive in establishment of observation networks for both ocean acidification/hypoxia (OAH) and harmful algal blooms, supported by local, state, and federal programs.

    HABs and ocean acidification: Additive, synergistic, antagonistic, or otherwise?

    Wednesday, June 17, 2020

    HABs and ocean acidification: Additive, synergistic, antagonistic, or otherwise?

    Dr. Chris Gobler discusses how harmful blooms and ocean acidification have emerged as two expanding threats to coastal ecosystems. Regardless of how acidification affects HABs, it is a clear environmental threat to a suite of calcifying invertebrates as well as other marine organisms including early life stage fish.  While HABs and acidification co-occur on coastal zones, their combined effects on marine life are very poorly understood.  This talk explores interactions between ocean acidification and HABs and implications of their co-occurrence for ocean organisms.
