HB4047, the Coastal Communities Ocean Acidification Act of 2025, amends the Federal Ocean Acidification Research And Monitoring Act of 2009 to require the Secretary of Commerce, through NOAA, to collaborate with state and local governments and Indian Tribes on vulnerability assessments, research planning, and related activities. The bill also expands NOAA's advisory structures, creates a formal ongoing input mechanism for on-the-ground stakeholders, and elevates Indian Tribes and Native Hawaiian organizations within the governance of ocean acidification research and monitoring, with a focus on informing coastal management and adaptation.
At a Glance
What It Does
The bill amends the OA Act to establish an ongoing input mechanism for affected industry members, coastal stakeholders, Indigenous groups, non-Federal resource managers, and scientific experts to provide input on research and monitoring. It also expands NOAA’s Advisory Board by adding two representatives from Indian Tribes and Native Hawaiian organizations, and requires a policy on engagement and coordination with Indigenous communities.
Who It Affects
NOAA leadership and staff, state and local governments, Indian Tribes, Native Hawaiian organizations, coastal communities, fishery management councils and commissions, and non-Federal researchers and community networks involved in ocean acidification work.
Why It Matters
By embedding local and Indigenous perspectives in OA research and planning, the bill aims to produce more relevant data and more effective adaptation strategies for coastal areas that are most at risk from acidification.

What This Bill Actually Does
This bill updates the Federal Ocean Acidification Research And Monitoring Act of 2009 to place greater emphasis on collaboration with state and local governments and Indigenous communities. It creates a formal mechanism for ongoing input from industry representatives, coastal stakeholders, Indigenous groups, and non-Federal scientists to inform NOAA’s research and monitoring in a tangible, on-the-ground way.
The act also expands the NOAA Advisory Board to include two representatives from Indian Tribes and Native Hawaiian organizations, and it revises board composition and appointment processes to ensure Indigenous participation. In addition, the bill requires NOAA to engage with state/local and tribal partners on vulnerability assessments, research planning, and related activities, with the aim of improving coastal resilience to ocean acidification.
The legislation also makes a set of technical corrections to ensure language around adaptation, mitigation, and collaboration is consistent and clear. Together, these changes are meant to align federal OA activities more closely with local needs and Indigenous knowledge, and to prioritize underserved communities in planning and resource allocation.
The Five Things You Need to Know
The bill creates an ongoing input mechanism for stakeholders to advise NOAA on OA research and monitoring.
The NOAA Advisory Board gains two representatives from Indian Tribes and Native Hawaiian organizations, and some board seats are reallocated.
NOAA must collaborate with state/local governments and Indigenous groups on vulnerability assessments and research planning.
The act directs better collaboration on vulnerability assessments and related activities, with a focus on underserved communities.
Technical corrections modernize language on adaptation, mitigation, and coordination across the OA program.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Section 1 designates the act as the Coastal Communities Ocean Acidification Act of 2025, establishing its formal identification within the U.S. code and signaling its policy focus on coastal resilience to ocean acidification.
Definitions
Section 2 adds and clarifies terms crucial to implementation, including Indian Tribe and Native Hawaiian organization, and it introduces terms like Subcommittee and United States to standardize references across the OA Act. These definitional updates widen stakeholder recognition and pave the way for broader collaboration.
Improvement of Collaboration on Ocean Acidification
Section 3 expands the collaboration framework. It creates an ongoing input mechanism (liaison structures, standing meetings, or an online platform) for affected industry members, coastal stakeholders, community acidification networks, and independent scientific experts to contribute to research and monitoring. It also broadens and adjusts the Advisory Board to include Indigenous representatives, and requires establishment of a policy for engagement with Indian Tribes within one year. The section further directs NOAA to integrate vulnerability assessments, research planning, and related activities with state/local and Indigenous partners to support on-the-ground management and adaptation.
Technical Corrections
Section 4 makes editorial and structural updates to the OA Act, tightening language around development, coordination, and implementation; aligning references to adaptation and mitigation; and ensuring that expansions to advisory and collaboration mechanisms are reflected consistently across sections.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Coastal communities gain access to more tailored research and planned adaptation informed by local and Indigenous input, improving resilience to ocean acidification impacts.
- Indian Tribes and Native Hawaiian organizations gain formal representation on the NOAA Advisory Board and a policy framework for engagement, ensuring their perspectives are integrated into OA research and management.
- State and local governments obtain clearer channels for collaboration with NOAA, enabling more coherent vulnerability assessments and community planning.
- Fisheries management councils and commissions benefit from direct input from Indigenous groups and coastal networks, supporting better co-management and adaptation.
- Non-Federal researchers and community acidification networks gain a structured avenue to influence data collection and monitoring aligned with local needs.
Who Bears the Cost
- NOAA will incur increased administrative costs to operate the ongoing input mechanism and expanded Advisory Board.
- State and local governments will devote staff time and resources to participate in the new consultation processes.
- Indian Tribes and Native Hawaiian organizations will need to allocate personnel to engage with the Advisory Board and participate in vulnerability assessment activities.
- Some private sector stakeholders may incur costs to participate in advisory activities and to share data or coordinate with federal programs.
- Non-Federal researchers and community networks may face time and resource costs to align with new reporting and coordination requirements.
Key Issues
The Core Tension
The central dilemma is balancing broad, inclusive collaboration with practical capacity and funding constraints. Expanding participation promises more relevant research and more equitable decision-making, but it also risks slowing processes or diluting priorities if resources do not keep pace with the expanded governance structure.
The bill meaningfully broadens who participates in OA research and planning, which can improve the relevance and usefulness of the data and the resulting management actions. However, it also increases the coordination burden on federal agencies, state and local governments, and Indigenous partners.
Without adequate funding and staffing, the expanded input mechanism could become aspirational rather than transformative. Realizing the intended benefits will require sustained resources, careful governance to avoid tokenism, and a clear process for reconciling diverse local needs with national OA priorities.
Questions remain about funding levels, data sharing standards, and how Indigenous knowledge will be integrated alongside scientific data in a way that respects tribal sovereignty.
