Hawaii Undersea Research Laboratory

The Hawaii Undersea Research Laboratory operates as a deep-sea research program based in Honolulu, Hawaii, supporting exploration of the Pacific Ocean and adjacent seamounts, mid-ocean ridge systems, and ocean trench environments. The laboratory collaborates with institutions including the University of Hawaiʻi at Mānoa, the National Oceanic and Atmospheric Administration, the National Science Foundation, and international partners such as the Smithsonian Institution and the Woods Hole Oceanographic Institution. HURL integrates human-occupied vehicles, remotely operated vehicles, and manned submersibles to study topics relevant to geology of the Pacific Ocean, marine biology, volcanology, and conservation biology.

Overview

HURL functions as a regional undersea research center within the framework of the NOAA Office of Oceanic and Atmospheric Research, conducting field operations from Honolulu Harbor and deploying vessels into the Central Pacific and along the Hawaiian–Emperor seamount chain. The laboratory maintains capabilities for deep submergence operations using platforms similar to those operated by the Woods Hole Oceanographic Institution, the Monterey Bay Aquarium Research Institute, and the Scripps Institution of Oceanography. HURL's mission supports research priorities set by the National Science Foundation, the U.S. Geological Survey, and the Office of Naval Research while contributing data to repositories like the National Centers for Environmental Information.

History and Development

HURL was established in 1980 through partnerships between the University of Hawaiʻi at Mānoa, NOAA, and the NSF to address scientific needs in the Central Pacific after landmark programs such as the Deep Sea Drilling Project and contemporaneous initiatives by the Woods Hole Oceanographic Institution. Early work built on discoveries at sites like Loʻihi Seamount and investigations associated with the Hawaiian hotspot and the Hawaiian–Emperor seamount chain. Over decades HURL adapted technologies from institutions including the Scripps Institution of Oceanography and the Monterey Bay Aquarium Research Institute and coordinated with agencies such as the U.S. Geological Survey and the National Marine Fisheries Service.

Research Programs and Projects

HURL supports multidisciplinary projects spanning marine geology, volcanology, hydrothermal vents, chemosynthetic ecosystems, and coral reef studies. Investigations have examined Loʻihi Seamount activity, Pāhoehoe and ʻAʻā lava morphologies, and seafloor mapping along the Hawaiian Rift Zone while informing hazard assessments used by the U.S. Geological Survey Hawaiian Volcano Observatory. Biological programs have surveyed endemic fauna like Hippocampus Hawaiianus-related taxa, deep-sea corals, and fauna associated with hydrothermal vent communities documented in collaborations with the Smithsonian Institution and the California Academy of Sciences. HURL contributes observational data to programs led by the National Oceanic and Atmospheric Administration and modeling efforts by NASA and the NOAA Pacific Marine Environmental Laboratory.

Fleet and Technology

HURL has operated human-occupied submersibles and remotely operated vehicles comparable to platforms at the Monterey Bay Aquarium Research Institute and the Woods Hole Oceanographic Institution, enabling dives to abyssal depths near features such as the Hawaii Deep Water areas, Kermadec Trench analogs, and Loʻihi Seamount. The fleet has interfaced with research vessels that include styles of ships used by the NOAA Ship Okeanos Explorer, the R/V Kilo Moana, and the R/V Maurice Ewing to support sea trials, mapping with multibeam echosounder systems, and sampling via benthic corer and ROV manipulators. Instrumentation has included vehicle-mounted CTD rosettes, high-definition video systems similar to those at the Monterey Bay Aquarium Research Institute, and navigation tied to GPS reference frames and acoustic positioning networks.

Partnerships and Funding

HURL's sustained operations rely on funding and programmatic partnerships with the National Oceanic and Atmospheric Administration, the National Science Foundation, the University of Hawaiʻi at Mānoa, and federal partners such as the Office of Naval Research and the U.S. Geological Survey. Scientific collaborations extend to the Smithsonian Institution, the California Academy of Sciences, the Monterey Bay Aquarium Research Institute, the Scripps Institution of Oceanography, and international institutions involved in Pacific research including the Australian Institute of Marine Science and New Zealand's National Institute of Water and Atmospheric Research. Funding models have combined federal grants, university support, and cooperative agreements with agencies including the National Oceanic and Atmospheric Administration and the National Science Foundation.

Notable Expeditions and Discoveries

HURL-led dives have yielded discoveries at Loʻihi Seamount including active hydrothermal venting, previously undocumented microbial mats, and novel invertebrate species noted by researchers from the Smithsonian Institution and the California Academy of Sciences. Expeditions produced high-resolution maps of the Hawaiian Rift Zone and documented deep coral assemblages informing assessments by the Pacific Islands Fisheries Science Center. HURL missions also contributed to rapid response investigations following events such as Kīlauea eruptive episodes that affected nearshore bathymetry and to collaborative projects with the U.S. Geological Survey Hawaiian Volcano Observatory.

Outreach and Education

HURL engages in outreach with the University of Hawaiʻi at Mānoa, regional museums such as the Bishop Museum, educational initiatives linked to the NOAA Office of Education, and public science programs associated with the Smithsonian Institution and the California Academy of Sciences. The laboratory supports student training through internships tied to the University of Hawaiʻi System and contributes multimedia resources for educators participating in programs run by the National Marine Educators Association and teacher workshops coordinated with the Pacific Marine Conservation Council.
