Okeanos Explorer (EX2405): Beyond the Blue: Johnston Atoll Mapping 1 + ORT
Vessel: Okeanos Explorer; Expedition Dates: August 19 - September 7, 2024
Project Principals: Shannon Hoy, NOAA/OAR/OER (Expedition Coordinator)
From August 19 - September 7, 2024 (Honolulu, Hawai'i to Hilo, Hawai'i), NOAA Ocean Exploration conducted mapping operations within the U.S. Exclusive Economic Zone outside of Johnston Atoll and Hawai'i, aiding in closing bathymetric gaps within this region. EX2405 collected 29,750 square kilometers of bathymetry and associated water column data. During mapping operations, NOAA Ocean Exploration simultaneously collected EM 304 multibeam sonar bathymetry observations and Simrad EK60/EK80 split-beam fisheries sonar observations of biologic material in the water column, as well as Knudsen 3260 sub-bottom profiler observations of sub-seafloor geologic structure and sediment. The exploratory mapping operations conducted during this cruise will provide initial characterization of the region, as well as data to support further exploration. Two days-at-sea of this expedition were dedicated to Operational Readiness Training (ORT) for NOAA Ship Okeanos Explorer officers and crew.
