Researchers Share Surprising Discovery about Coral Reef Ecology

Researchers at the UH Manoa School of Ocean and Earth Science and Technology (SOEST) made a discovery that challenges a major theory in the field of coral reef ecology.

The general assumption has been that the more flexible corals are, regarding which species of single-celled algae (Symbiodinium) they host in coral tissues, the greater ability corals will have to survive environmental stress. In their paper published August 29, 2012, however, scientists at the Hawaii Institute of Marine Biology (HIMB) at SOEST and colleagues documented that the more flexible corals are, the more sensitive to environment disturbances they are.

Scientists Discover Land-Ocean Connections off Moloka’i

*Tree trunks, leaves, and kukui nuts indirectly feed bottom fish in submarine canyons off Moloka’i*

Scientists from UH Mānoa’s School of Ocean and Earth Science and Technology (SOEST) recently discovered that land-based plant material and coastal macroalgae indirectly support the increased abundances of bottom fish in submarine canyons, like those off the north shore of Moloka’i. Less than a few miles from the shore, these underwater canyons connect to deep river valleys that cut across the landscape of north Moloka’i. The high elevation and forested landscapes along Moloka’i’s north shore provide plant material, including decomposing tree trunks, leaves and tons of kukui nuts, which enter the ocean via river valleys and “pile up” on submarine canyon floors.

Scientists Project Changes in Rainfall Patterns for Next 30 Years

Scientists at the University of Hawaiʻi at Mānoa have projected an increased frequency of heavy rainfall events, but a decrease in rainfall intensity during the next 30 years (20112040) for the southern shoreline of Oʻahu, according to a recent study published in the Journal of Geophysical Research.

Chase Norton, a Meteorology Research Assistant at the School of Ocean and Earth Science and Technology (SOEST) at UH Mānoa, and colleagues (Professors Pao-Shin Chu and Thomas Schroeder) used a statistical model; rainfall data from rainfall gauges on Oahu, Hawaiʻi; and a suite of General Circulation Models (GCMs) from the Intergovernmental Panel on Climate Change (IPCC) to project future patterns of heavy rainfall events on Oʻahu. GCMs play a pivotal role in the understanding of climate change and associated local changes in weather. (more…)

Three Year Investigation of Military Munitions Sea Disposal Site Completed

The University of Hawaiʻi at Mānoa’s School of Ocean Earth Science and Technology (SOEST) completed a three-year long investigation of Sea Disposal Site Hawaiʻi Number 5 (HI-05), a deep-water military munitions disposal site in U.S. coastal waters approximately 5 miles south of Pearl Harbor, Oʻahu, Hawaiʻi.
