NOAA Ocean Exploration is soliciting proposals for ocean exploration-related projects under two themes: Ocean Exploration and Maritime Heritage. By supporting exploration (i.e., examining unknown or poorly understood areas of the seafloor, sub-bottom, or water column through initial assessments of the physical, chemical, geological, biological, archaeological, or other characteristics), NOAA Ocean Exploration seeks to advance our basic understanding of the unknown ocean. All proposed projects must support priorities in the NOAA Ocean Exploration Strategic Plan (https://oceanexplorer.noaa.gov/about/what-we-do/media/noaa-oe-strategic-plan_fy23-fy27.pdf) and should also consider the Strategic Priorities for Ocean Exploration and Characterization of the United States Exclusive Economic Zone (https://www.whitehouse.gov/wp-content/uploads/2022/10/NOMEC_OEC_Priorities_Report.pdf). Proposed projects are not restricted to waters under U.S. jurisdiction, but proposals should address how projects will provide national benefit.For Fiscal Year 2025 (FY25) funding, NOAA Ocean Exploration is soliciting proposals focused on one of the following two themes:OCEAN EXPLORATION: Ocean Exploration proposals should support exploration of unknown or poorly known ocean areas, processes, or resources in waters deeper than 200 meters or in tropical mesophotic environments. Projects can entail conducting ocean exploration (e.g., mapping and characterizing ocean habitats, combining seismic and acoustic methods), advancing ocean exploration through the use or development of novel technologies (e.g., autonomous systems, nondestructive sensors, artificial intelligence/machine learning), and/or analysis of ocean exploration datasets or samples that already exist and are publicly accessible. NOAA Ocean Exploration is particularly interested in projects that explore the physical, chemical, and biological environments and processes in the deep oceanic water column and projects that will improve genetic libraries for species-level environmental DNA (eDNA) analysis of deep-sea species. All proposals must demonstrate how the proposed project relates to at least one of the exploration variables identified by NOAA Ocean Exploration (https://oceanexplorer.noaa.gov/data/publications/exploration-variables.html).MARITIME HERITAGE: Maritime Heritage proposals should address the exploration for significant maritime heritage resources that improve our understanding of the past and inform decisions about management and preservation. Maritime heritage projects can be conducted at any water depth. NOAA Ocean Exploration is particularly interested in proposals that target conflict archaeology, incorporate Indigenous knowledge, or perform wide-area searches in areas poorly mapped for maritime heritage. NOAA Ocean Exploration welcomes the use of innovative technology and/or methods for quantitative assessment of targets to improve archaeological site identification and documentation.Informational documents about this funding opportunity are on the NOAA Ocean Exploration website at https://oceanexplorer.noaa.gov/about/funding-opps/welcome.html.All links were valid as of the date of the publication of this notice.

These registrations include SAM.gov, Grants.gov, and eRA Commons. All registrations must be completed prior to the application being submitted. The complete registration process for all three systems can take 4 to 6 weeks, so applicants should begin this activity as soon as possible. If an eligible applicant does not have access to the internet, please contact the Agency Contacts (see in Section IV.A.) for submission instructions.Prior to registering with eRA Commons, applicant organizations must first obtain a Unique Entity Identifier (UEI) from SAM.gov, if needed (see Section IV.C). Organizations can register with eRA Commons in tandem with completing their full SAM and Grants.gov registrations; however, all registrations must be in place by time of application submission. eRA Commons requires organizations to identify at least one Signing Official (SO) and at least one Program Director/Principal Investigator (PD/PI) account in order to submit an application.
