Sea-level rise online map viewer now available for Hawaii, Guam, and CNMI

Hanalei, Kauai sea-level rise map

The National Oceanic and Atmospheric Administration (NOAA) released a web-mapping tool aimed at visualizing potential impacts from sea-level rise in Hawai’i, Guam and the Commonwealth of the Northern Marianas Islands (CNMI).  Known as the Sea Level Rise and Coastal Flooding Impacts Viewer, the tool serves as a simple and easy to use but powerful planning resource for planners, public officials, ...

[VIDEO] How to launch a 13-ton submarine (Part 1)

Submarine

The Hawai‘i Undersea Research Laboratory (HURL) specializes in providing scientists with the tools and expertise they need to investigate the undersea environment, including submersibles, remotely operated vehicles, and other cutting edge technologies. This Center, within the School of Ocean and Earth Sciences and Technology at the University of Hawai‘i, is funded through a cooperative agreement from NOAA that began in ... Read More »

Female tiger sharks migrate from Northwestern to Main Hawaiian Islands during fall pupping season

Applying a tag to a shark

A quarter of the mature female tiger sharks plying the waters around the remote coral atolls of the Northwestern Hawaiian Islands decamp for the populated Main Hawaiian Islands in the late summer and fall, swimming as far as 2,500 kilometers (1,500 miles) according to new research from University of Florida and the University of Hawaii. Their report is scheduled for ... Read More »

Sea-level rise drives shoreline retreat in Hawaii, study reveals

Coastal erosion

Sea-level rise (SLR) has been isolated as a principal cause of coastal erosion in Hawaiʻi. Differing rates of relative SLR on the islands of Oʻahu and Maui remain as the best explanation for the difference in island-wide shoreline trends (that is, beach erosion or accretion) after examining other influences on shoreline change including waves, sediment supply and littoral processes, and ...

Submarine canyons a source of marine invertebrate diversity, abundance

submarine canyons

Submarine canyons play an important role in maintaining high levels of biodiversity of small invertebrates in the seafloor sediments of the main and northwestern Hawaiian Islands, according to research from the University of Hawai‘i at Mānoa. What’s more, scientists have used this data to draw new connections between the levels of faunal diversity and the heterogeneity of submarine canyon landscapes ... Read More »

Ocean fish acquire more mercury at depth

Anela-opah-auction-web

Mercury—a common industrial toxin—is carried through the atmosphere before settling on the ocean and entering the marine food web. Now, exciting new research from the University of Michigan and the University of Hawai‘i at Mānoa School of Ocean and Earth Science and Technology (SOEST) combines biogeochemistry and direct marine ecology observations to show how the global mercury cycle is colliding ...

New method of estimating fish movements underwater

Monitoring Station - Close Up

How do you track a fish? There’s no “Google Maps” for finding fish. The radio signals that are the backbone of traditional GPS cannot pass through seawater. But sound travels remarkably well, so scientists often use acoustic telemetry to estimate an individual fish’s location. That means attaching an acoustic transmitter to a fish and then using a network of stationary ... Read More »

Carbon emissions to impact climate beyond the day after tomorrow

Calving Glacier

Future warming from fossil fuel burning could be more intense and longer-lasting than previously thought. This prediction emerges from a new study by University of Hawaiʻi at Mānoa oceanographer Richard Zeebe, who includes insights from episodes of climate change in the geologic past to inform projections of man-made future climate change. The study is published in the Proceedings of the ... Read More »

Plastic for dinner? Big fish eat more than you expect

Large, predatory fishes from the offshore waters around Hawai‘i have been ingesting a surprisingly large amount of plastic and other marine debris, according to new research by scientists at the University of Hawai‘i at Mānoa. These observations are the first of their kind in scope and in number, and they suggest that more attention should be given to marine debris ... Read More »

Laser scanning confocal microscope generates artful images of science

Confocal Image of Coral

Corals are beautiful when seen through your own eyes in sunlight, but for scientists at the University of Hawaiʻi at Mānoa, seeing corals in this manner is simply not enough. As part of a new PBS digital video series called UnderH20, viewers see live corals–and their associated microorganisms–from a whole new perspective. Using a revolutionary new tool, a laser scanning ... Read More »
