Research team discovers intact ‘ghost ship’ off the coast of Oahu

The USS Kailua, 1943.

Researchers from the University of Hawai‘i at Mānoa and NOAA’s Office of National Marine Sanctuaries today announced the discovery of an intact “ghost ship” in 2,000 feet of water nearly 20 miles off the coast of Oʻahu.  Sitting upright, its solitary mast still standing and the ship’s wheel still in place, the hulk of the former cable ship Dickenson, later the ...

Climate researchers discover El Nino’s fueling effect on intense hurricanes

Typhoon Vicente

El Niño, the abnormal warming of sea surface temperatures in the Pacific Ocean, is a well-studied tropical climate phenomenon that occurs every few years. It has major impacts on society and Earth’s climate – inducing intense droughts and floods in multiple regions of the globe. Further, scientists have observed that El Niño greatly influences the yearly variations of tropical cyclones ... Read More »

Another human footprint in the ocean: Rising anthropogenic nitrate levels

boat deck

Human-induced changes to Earth’s carbon cycle – for example, rising atmospheric carbon dioxide and ocean acidification – have been observed for decades. However, a study published this week in Science showed human activities, in particular industrial and agricultural processes, have also had significant impacts on the upper ocean nitrogen cycle. The rate of deposition of reactive nitrogen (i.e., nitrogen oxides ... Read More »

CT scans of coral skeletons reveal ocean acidity increases reef erosion

Colony of rare corals

Coral reefs persist in a balance between reef construction and reef breakdown. As corals grow, they construct the complex calcium carbonate framework that provides habitat for fish and other reef organisms.  Simultaneously, bioeroders, such as parrotfish and boring marine worms, break down the reef structure into rubble and the sand that nourishes our beaches. For reefs to persist, rates of ... Read More »

Study reveals tiger shark movements around Maui and Oahu

Shark_Tag1_web

UH Mānoa researchers are using tracking devices to gain new insights into tiger shark movements in coastal waters around Maui and O‘ahu. The ongoing study reveals their coastal habitat preferences “We need to understand tiger shark movements in our coastal waters to gain a clearer comprehension of the circumstances bringing sharks and humans together,” said Dr. Kim Holland, senior shark scientist at the ...

EPA grants recognize two grad students working with corals

Colony of rare corals

The U.S. Environmental Protection Agency (EPA) announced $168,000 in fellowship grants to two graduate students at the Hawai‘i Institute of Marine Biology (HIMB). John Burns and Raphael Ritson-Williams were named as recipients of the Science to Achieve Results (STAR) fellowship. Burns’ research will focus on the relationship between land-based sources of pollution and coral reef ecosystem function off the Hamakua ... Read More »

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 ...

Seafood substitutions can expose consumers to unexpectedly high mercury

Fish market

New measurements from fish purchased at retail seafood counters in 10 different states show the extent to which mislabeling can expose consumers to unexpectedly high levels of mercury, a harmful pollutant. Fishery stock “substitutions”—which falsely present a fish of the same species, but from a different geographic origin—are the most dangerous mislabeling offense, according to new research by University of ...
