4. NOAA Ocean Exploration Announces FY24 Ocean Exploration Funding Opportunity Awards

NOAA Ocean Exploration selected four projects for financial support through its Ocean Exploration Fiscal Year 2024 (FY24) Funding Opportunity. Totaling over $2.1 million, these projects will explore the mesophotic coral ecosystems off the western coast of Puerto Rico, study the biodiversity of deep-pelagic crustaceans from the waters off Southern California, explore and document a collection of nationally significant shipwrecks in the deep waters of Lake Michigan’s Wisconsin Shipwreck Coast National Marine Sanctuary, and more.

NOAA Ocean Exploration explores the ocean to help us as a society better understand what lives and lies in its great depths and how it supports and affects life on Earth. One of the tools we use to do this is an annual competitive grant program.

For the FY24 competition, we invited proposals for projects under the themes of ocean exploration and discovery, maritime heritage, and technology that support national priorities, including the Strategic Priorities for Ocean Exploration and Characterization of the United States Exclusive Economic Zone and NOAA’s science and technology priorities.

Three of the supported projects are described below (the fourth will be announced later).

Characterizing Mesophotic Fish Assemblages of Puerto Rico’s Western EEZ

Principal Investigator: Richard R. Coleman, University of Miami

Mesophotic (“middle light”) coral ecosystems provide habitat for an array of vulnerable and ecologically and commercially important fish species. At ocean depths between the brightly lit shallows and the dark deep ocean (30-150 meters/98-492 feet) in tropical and subtropical regions, these ecosystems are difficult to access, meaning they’re relatively unexplored, and our knowledge about the fish that inhabit them is limited. Using advanced deep-diving techniques and data collection methods, this research team will explore the mesophotic coral ecosystems off the western coast of Puerto Rico to better understand these ecosystems and how they are used as habitat by their associated fish communities. Technical divers will conduct complementary stereo-video and visual surveys to document fish occurrence, size, and abundance as well as evidence of marine debris, bleaching, disease, and other threats. They’ll also collect samples of select uncommon, rare, and unknown species for further study and water samples for eDNA analysis. The results of this project will inform the conservation and management of Puerto Rico’s mesophotic coral ecosystems and the fish communities they support and serve as a baseline against which to assess future changes.

Exploration and Characterization of Deep-Pelagic Crustacean Diversity in the Southern California Exclusive Economic Zone

Principal Investigator: C. Anela Choy, Scripps Institution of Oceanography

The deep ocean is the largest living space on Earth, and the deep-pelagic (or water column) species that live there are important food sources for marine predators, including ecologically, culturally, commercially, and recreationally important species. Scientists have much to learn about the biodiversity and ecology of deep-pelagic crustaceans and their associated communities. During this lab-based project, the research team will study the biodiversity of crustaceans collected from the deep waters off Southern California, with a focus on three orders of dominant crustaceans (Decapoda, Lophograstrida, and Mysida). Specifically, they will identify — or document and describe if unknown — recently collected crustaceans from five sites based on their morphology (form and structure). These identifications will be complemented with DNA studies. Using this information, they will characterize crustacean community composition in the study area. Upon completion of their research, they will deposit the samples and the associated genetic material and data in national collections and databases and produce a pictorial guide of deep-pelagic crustaceans. This work will support future water column exploration, research, and monitoring throughout the ocean to help us better understand the value and services of our natural marine resources and inform their sustainable management and use.

Exploring the Wisconsin Shipwreck Coast National Marine Sanctuary at Scale

Principal Investigator: Russ Green, Wisconsin Shipwreck Coast National Marine Sanctuary

Well preserved by cold freshwater, the Great Lakes possess some of the most extraordinary potential for archaeological investigation of historic shipwrecks anywhere in the world. Many of these shipwrecks have yet to be discovered or explored. This research team will explore and document a collection of nationally significant shipwrecks — five recently located but not yet documented — in the deep waters (130-480 feet) of Lake Michigan’s Wisconsin Shipwreck Coast National Marine Sanctuary. They will use a hybrid autonomous underwater vehicle/remotely operated vehicle (AUV/ROV) equipped with novel acoustic, imaging, and laser scanning sensors, and develop new archaeological methods to capitalize on the efficiencies of autonomous and uncrewed vehicles. This project will produce baseline data and information — including still and video imagery and photogrammetric and laser-scan models — that will inform the sanctuary’s monitoring and preservation efforts and contribute to the understanding of the role of the Great Lakes in our nation’s maritime heritage.
