Autonomous Vehicles Powered by Ocean Waves Support NOAA Fisheries Research

December 4, 2023 — Scientists from NOAA’s Pacific Islands Fisheries Science Center are using autonomous surface vehicles called Wave Gliders to study ocean health in Hawaiʻi. Wave Gliders are circumnavigating each of the Hawaiian Islands. They’re collecting data on ocean conditions that will be used to help estimate the impacts of climate change on marine ecosystems and fisheries across the state.

“We are primarily interested in measuring chlorophyll, which provides a good estimate of phytoplankton biomass in the ocean,” said Dr. Jamison Gove, an oceanographer with the Pacific Islands Fisheries Science Center and co-lead scientist on the project. “Phytoplankton are the basis for productive and healthy ecosystems, so knowing where and how much phytoplankton there are in the ocean aids in understanding the entire marine food-web,” added Dr. Gove.

The Building Blocks of Ocean Ecosystems

Phytoplankton are microscopic plants that live near the ocean surface. They are similar to land-based plants: They contain chlorophyll and require sunlight to live and grow. Phytoplankton are the base of the food chain. Their biomass—the total amount of them in a given region of the ocean—dictates fisheries yields and ecosystem productivity across the world.

NOAA expedition off Kona unearths mysterious deep sea creatures

September 29, 2016 — Nearly three quarters of the Earth is taken up by the ocean but NOAA scientists say less than five percent of its have ever been explored.

NOAA fisheries is on a mission to expand our understanding. Researchers just wrapped up an expedition off the Kona Coast. 20 scientists spent 20 days in waters off West Hawai’i known for it’s thriving ocean environment.

“We’re trying to really pinpoint some of the primary mechanism’s…primary reasons why this ecosystem is so productive,” said Jamison Gove, a NOAA Oceanographer.

Scientists discovered an abundant community of creatures 2,000 feet down that possessed out of the ordinary features.

“Huge teeth… they’re all very strange looking. They have adapted to life where there’s virtually no light, food is incredibly scarce and if you come across a meal you have to be able to grab it,” said Jonathan Whitney, a NOAA Biologist.

The mysterious species are believed to be an important food source to larger marine mammals like dolphins.

Large trawl nets scooped up organisms from the deep depths and near the surface in an area known as the surface slicks. The visibly smooth ribbon like section pulls together floating material and serves as somewhat of a nursery for young marine life.
