U.N. task force says new ocean telecom cables should be ‘green’

global undersea communications cable infrastructure

The global system of submarine telecommunications cables that supports our connected world is deaf, dumb and blind to the external ocean environment – and represents a major missed opportunity for tsunami warning and global climate monitoring, according to UH scientists and a United Nations task force. “For an additional 5-10 percent of the total cost of any new cable system ...

New study shows the importance of jellyfish to deep-sea ecosystem

Jellyfish baits in the deep sea

This week, researchers from University of Hawai‘i, Norway, and the UK have shown with innovative experiments that a rise in jellyfish blooms near the ocean’s surface may lead to jellyfish falls that are rapidly consumed by voracious deep-sea scavengers.Previous anecdotal studies suggested that deep-sea animals might avoid dead jellyfish, causing dead jellyfish from blooms to accumulate and undergo slow degradation ...

Ocean’s most abundant organisms have clear daily cycles

Planktonic microbes

Imagine the open ocean as a microbial megacity, teeming with life too small to be seen. In every drop of water, hundreds of types of bacteria can be found.  Now scientists have discovered that communities of these ocean microbes have their own daily cycles—not unlike the residents of a bustling city who tend to wake up, commute, work, and eat ...

New study reveals whales as marine ecosystem engineers

Whale feeding habitats

Baleen and sperm whales, known collectively as the great whales, include the largest animals in the history of life on Earth. Though large in size, whales have long been considered too rare to make much of a difference in the ocean, and the focus of much marine ecological research has been on smaller organisms, such as algae and planktonic animals. ...

Fostering Hawaii’s young marine scientists one expedition at a time

Student with MOCNESS net

On Thursday, June 19, 2014, University of Hawai‘i marine science students returned from the last of three research expeditions aboard Schmidt Ocean Institute’s R/V Falkor. The group sailed to Station ALOHA, a long-term ocean sampling site 60 miles north of O‘ahu. The 11 students on this past cruise makes a total of 58 UH students (graduates and undergraduates) who have ... Read More »

Antarctic ice-sheet less stable than previously assumed

Iceberg in Scotia Sea

The first evidence for massive and abrupt iceberg calving in Antarctica, dating back 19,000 to 9,000 years ago, has now been documented by an international team of geologists and climate scientists. Their findings are based on analysis of new, long deep sea sediment cores extracted from the region between the Falkland Islands and the Antarctic Peninsula. The study in the ... Read More »

Precursor volcano to the island of O‘ahu discovered

Map showing volcanoes thought to have made up the region of O‘ahu, Hawai‘i

  Researchers from the University of Hawai‘i at Mānoa (UHM), Laboratoire des Sciences du Climat et de L’Environment (France), and Monterey Bay Aquarium Research Institute recently discovered that O‘ahu actually consists of three major Hawaiian shield volcanoes, not two, as previously thought.  The island of O‘ahu, as we know it today, is the remnants of two volcanoes, Wai‘anae and Ko‘olau.  But ...

UH Mānoa graduate student John Burns has been selected as a finalist for the Rolex Awards for Enterprise. From a pool of more than 1,800 applicants from 129 countries around the world, Burns is one of 22 finalists.  The award is targeted to innovators under 30 years of age. The Papaikou resident is one of only three finalists from the United ... Read More »

The Pavel’s $10M gift invests in premier UH expertise in ocean, earth and sky

Guenther Hasinger

When Victor and Margaret (Peggy) designated the University of Hawai‘i Foundation as the primary beneficiary of their estate, they wanted to keep their identity private and preferred no personal publicity for what would turn out to be the largest estate gift to UH in UH history. Fortunately, they gave us permission to posthumously acknowledge them, and let Hawai‘i know who ... Read More »

HURL enables discovery of dramatic long-term shift in Pacific Ocean ecosystem

Hawaiian gold coral

The Hawaii Undersea Research Laboratory (HURL) at the University of Hawai’i at Mānoa School of Ocean and Earth Science and Technology (SOEST) has enabled scientists to determine that a long-term shift in nitrogen content in the Pacific Ocean has occurred as a result of climate change.   Researchers from the Lawrence Livermore National Laboratory (LLNL) and the University of California – Santa Cruz analyzed ...
