Interactions of Ocean Acidification and Harmful Algal Blooms

Session ID#: 85201

Session Description:
Both Harmful Algal Blooms (HABs) and Ocean Acidification (OA) are threats to marine ecosystems and human communities in the coastal zone. Although many areas of research have provided insights into the factors that govern HAB bloom dynamics, toxicity and impacts, only a few of these have included OA. Similarly, OA studies have examined ocean biogeochemistry and impacts to marine resources and economies, and have started to expand into multiple stress studies (e.g. with hypoxia and warming). Less is known about the influences of OA – HAB interactions and cascading impacts to coastal ecosystems, communities and economies. In this session, we invite presentations that examine HABs and OA impacts together. Are OA and HAB dynamics linked? Does OA influence growth and/or toxicity of HABs? What are food web impacts of combining OA and HABs? Are some marine species more vulnerable/resilient to combined OA and HAB impacts? What are resulting impacts to fisheries and coastal economies? Can we make projections about future conditions? How can we encapsulate information about combined impacts into useful information for management and policy makers? What are the major gaps in our understanding? We welcome submissions from a wide variety of perspectives to help us shape future research initiatives.
