Original scientific research by two recent graduates from the University of Hawaiʻi at Mānoa’s Global Environmental Science (GES) undergraduate program has shed new light on Hawaiʻi’s past and current natural environment. Present day stressors on a traditional Hawaiian fishpond Camilla Tognacchini’s senior research project began with the goal to assess how the removal of invasive mangroves affects the health of ...

Corals worldwide hit by bleaching

The current coral bleaching event began last year in the Pacific Ocean. This reef in American Samoa was healthy in December 2014 (left) but had lost its characteristic colour in February 2015 (right). Image courtesy of XL Catlin Seaview Survey.

From Hawai‘i to Papua New Guinea to the Maldives, coral reefs are bleaching — in so many regions that the US National Oceanographic and Atmospheric Administration (NOAA) officially declared a global bleaching event on 08 October 2015. The event, the third in recorded history, is expected to grow worse in coming months. Warm ocean temperatures, linked to climate change and ...

When the eastern flank of Fogo, a Cape Verde volcano, splashed into the sea some 73,000 years ago, it generated an enormous wave that rose to 170 meters of height before it crashed into a nearby island, geophysicists have discovered. The mega-tsunami, reported on 2 October 2015 in Science Advances, is one of the largest in the geological record. The flanks ...

Three marine mammals that have been involved in hearing and underwater noise studies at the University of Hawaiʻi at Mānoa for more than 20 years have been relocated to Sea Life Park. Kina, a 40-year-old female Pseudorca; Boris, a 26-year-old male Tursiops and BJ, a 29-year-old female Tursiops, came to UH with Paul Nachtigall in 1993, when he founded the ...

Many tropical Pacific island nations are struggling to adapt to gradual sea level rise stemming from warming oceans and melting ice caps. Now they may also see much more frequent extreme interannual sea level swings. The culprit is a projected behavioral change of the El Niño phenomenon and its characteristic Pacific wind response, according to recent computer modeling experiments and ...

U.S. Coast Guard Cutter Healy, home-ported in Seattle, arrived at the North Pole this week, becoming the first U.S. surface ship to do so unaccompanied. This is only the fourth time a U.S. surface vessel has ever reached the North Pole, and the first since 2005. Healy’s crew and science party, including several scientists and a graduate student from the ...
