For FY25, these themes are defined as follows: 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. 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 (Award Ceiling: $1M). 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. 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 (Award ceiling: $750K). Preproposals required: May 30, 2024. Full proposals due: October 3, 2024.
