In the microscopic life that thrives around coral reefs, a team of researchers, including Katie Barott, postdoctoral researcher at the University of Hawaiʻi at Mānoa’s Hawaiʻi Institute of Marine Biology, have discovered an interplay between viruses and microbes that defies conventional wisdom. As the density of microbes rises in an ecosystem, the number of viruses infecting those microbes rises with ...

During a test dive last week, the Hawaiʻi Undersea Research Laboratory (HURL) recovered a bronze bell from the I-400—a World War II-era Imperial Japanese Navy mega-submarine, lost since 1946 when it was intentionally sunk by U.S. forces after its capture. Longer than a football field at 400 feet, the I-400 was known as a “Sen-Toku” class submarine—the largest submarine ever built until ...

Researchers from the University of Hawaiʻi botany department and Friday Harbor Laboratorieshave discovered and described four new algal species from Hawaiʻi’s mesophotic coral ecosystems. The new species (Ulva ohiohilulu, Ulva iliohaha, Umbraulva kuaweuweu, and Umbraulva kaloakulau) are part of a group commonly known as sea lettuces. Sea lettuces are not well described in mesophotic environments (100–500 feet deep), but are known from shallow waters worldwide. This ...

Helping Hawaiʻi prepare for coastal hazards aim of NOAA grant

Shoreline erosion, North Shore of Oʻahu

To help Hawaiʻi communities reduce their vulnerability to natural hazards and climate change, NOAA’s National Ocean Service awarded the University of Hawaiʻi Sea Grant College Program (Hawaiʻi Sea Grant) $845,160 in grant funding through the Regional Coastal Resilience Grants Program. Hawaiʻi is particularly vulnerable to coastal hazards. Since the state is heavily reliant on tourism, and most of the development and infrastructure in Hawaiʻi are ...

Disaster preparedness the focus of Pacific Risk Management ʻOhana conference

Infrared images from NOAA’s GOFS and IMA’s MTSAT geostationary satellites. For each of the 15 tropical cyclones this season, a daily image was extracted from the period when the cyclone was active in the Central North Pacific basin.

On Wednesday, March 16, the University of Hawaiʻi, a member of the Pacific Risk Management ʻOhana (PRiMO), will be co-hosting a free community event on disaster preparedness at the Hawaiʻi Convention Center from 3:30 to 7 p.m. In addition to expert speakers on topics related to insurance, climate adaptation and making cities more resilient, there will be many displays, demonstrations and activities for ...

Plankton network linked to ocean’s biological carbon pump revealed

The biological carbon pump is the process by which carbon dioxide (CO2) is transformed to organic carbon via photosynthesis, exported from the surface ocean as sinking particles and finally sequestered in the deep sea. While the intensity of the pump is directly correlated to the abundance of certain plankton species—free-floating micro-organisms—the underlying ecosystem structure driving the process has remained poorly ...
