The ship Okeanos Explorer, from the National Oceanic and Atmospheric Administration, left the port on O‘ahu last week to begin two months of dives using unmanned remotely operated vehicles, or ROVs, to explore marine protected areas in the central Pacific Ocean.
Since Aug. 1, anyone with an Internet connection can virtually explore deep sea habitats and marine life with scientists and researchers from their computer or mobile device, according to NOAA. The expedition will last until Sept. 30.
The ship and its crew will investigate deeper waters in and around Papahanaumokuakea Marine National Monument in the Northwestern Hawaiian Islands, Johnston Atoll in the Pacific Remote Islands Marine National Monument, and the Hawaiian Islands Humpback Whale National Marine Sanctuary.
“These areas represent some of the last relatively pristine marine ecosystems on the planet,” said Holly Bamford, assistant NOAA administrator for the National Ocean Service performing the duties of the assistant secretary of commerce for conservation and management.
“NOAA explores these regions because the data and information we gather helps scientists and resource managers better understand and protect these biological, geological and cultural resources that we are already aware of and those we will discover in the future,” he said.
The expedition team will explore the seafloor at depths of 1,300 to 16,250 feet (400 to 5,000 meters) with two ROVs, which are tethered to Okeanos Explorer. The vehicles are outfitted with multiple high-definition cameras to capture imagery, which the ship will transmit back to shore. Scientists will participate virtually, guiding the expedition from shore, while the public can tune in and view the exploration in real time at oceanexplorer.noaa.gov.
The work around Johnston Atoll will be the largest scientific effort conducted there since President Obama expanded the Pacific Remote Islands Marine National Monument in September 2014.
“These places provide invaluable habitat for corals, birds and many other species — that’s one of the reasons they’ve been protected — but we don’t know much about what’s in the deep-sea areas,” said Samantha Brooke, manager for NOAA’s Marine National Monument Program in the NOAA Fisheries.
Expedition leaders anticipate finding large deep-sea coral communities known as coral gardens — some with coral colonies thought to be thousands of years old — as well as sponge communities. Both coral gardens and sponge communities provide habitat for a number of other species.
“Given the unexplored nature of these areas, their remoteness and their known status as biodiversity hotspots, I’d be very surprised if we didn’t see many animals and phenomena that are new to science,” said expedition science team lead Christopher Kelley, associate professor of biology and program biologist at the Hawai‘i Undersea Research Laboratory, University of Hawai‘i at Manoa.
Okeanos Explorer just completed two weeks of mapping more than 10,300 square miles (26,700 square kilometers) of seafloor around Johnston Atoll, which is part of the Pacific Remote Islands Marine National Monument.
“Papahanaumokuakea and the sanctuary are home to numerous protected species, undiscovered shipwrecks and sacred maritime landscapes,” said Allen Tom, Pacific Islands regional director of NOAA’s Office of National Marine Sanctuaries. “With live streaming video, we will be providing an exciting way for people to ‘visit’ these special places.”
The Pacific Remote Islands and Papahanaumokuakea marine national monuments were established by Presidential proclamations to protect abundant populations of coral, fish, marine mammals and seabirds. Papahanaumokuakea was also established to protect Native Hawaiian heritage and cultural resources.
The Hawaiian Islands Humpback Whale National Marine Sanctuary was created by Congress to protect humpback whales and their habitat in Hawai‘i.
This is the first expedition of a major three-year effort to systematically collect information to support science and management needs within and around the U.S. marine national monuments and NOAA’s national marine sanctuaries in the Pacific.
NOAA’s mission is to understand and predict changes in the Earth’s environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Join NOAA on Twitter, Facebook, Instagram and other social media channels.
