CA Ocean Protection Council Prop 68 and California Sea Grant Competitive Call for Monitoring, Research, and Synthesis Projects that Support Improved Understanding of Chemical and Ecological Sensitivity and Adaptation to Ocean Acidification and Hypoxia.


Letters of Intent: August 30, 2021 – 5 p.m. PT
Full Proposals*: October 7, 2021 – 5 p.m.  PT
*Only applicants who have submitted a letter of intent may submit a full proposal.

A consequence of increased global carbon dioxide emissions and nutrient loading, ocean acidification and hypoxia (OAH) trigger a wide range of marine ecosystem impacts and often co-occur, thus presenting a collective management challenge for the West Coast region. The impacts of ocean acidification disproportionately affect sensitive species, mainly calcifying marine organisms, many of which support important commercial fisheries, though additional evidence indicates that such impacts may extend throughout food webs. Similarly, low dissolved oxygen or hypoxic events are increasing in frequency and extent across the West Coast, threatening the resilience and stability of marine ecosystems. High temperatures can also cause or exacerbate hypoxia, as can high nutrient loadings, the the latter of which occurs independent of greenhouse gas emissions. Further investigation is needed to understand the interactions between such covariates, specifically field-based research and monitoring. The main findings from awarded proposals will be used by the state to support actions on OAH (e.g. establishing water quality objectives and nutrient loading standards) by 2025. 

California Sea Grant and the California Ocean Protection Council (OPC) are now soliciting proposals for monitoring, research, and synthesis projects that will enhance our understanding of ocean acidification and hypoxia on biological vulnerability. This funding opportunity will support the collection of new chemical or ecological observations or species response data. Synthesis efforts that promote broad access and sharing of OAH data and information are also eligible.

California Sea Grant and OPC are soliciting proposals for projects of up to 3 years in duration, with a maximum budget of $1,000,000 per project (to include indirect costs, if any).  Two to seven projects will likely be funded and range from a minimum of $200,000 to a maximum of $1,000,000, contingent upon receipt of anticipated funds from NOAA. The anticipated start date of these projects is approximately February 1, 2022. There is a total of $2.2 million available for this research solicitation. California Sea Grant will fund $400,000 worth of projects and OPC will provide an additional $1,800,949. 

The intent of the planned solicitation is to meet OPC’s Strategic Plan Objective 1.2 to minimize causes and impacts to ocean acidification and hypoxia and Objective 1.3 to improve understanding of climate impacts on California’s coast and ocean. The solicitation will also be aligned with the recommendations made by the California Ocean Acidification and Hypoxia (OAH) Science Task Force report “Enhancing California’s Ocean Acidification and Hypoxia Monitoring Network”, a joint effort led by the OPC and Ocean Science Trust (OST). California Sea Grant will contribute NOAA Sea Grant funds and administer the solicitation which will be focused on projects of up to 3 years in duration that enhance our understanding of OAH impacts to biological, economic, and social vulnerability through enhanced monitoring, research, and synthesis. California Sea Grant will also lead grant administration on behalf of OPC.
