Hawaii Ocean Time-series (HOT)

The Hawaii Ocean Time-series program has been making repeat measurements at Station ALOHA since 1988. Such time series observations are necessary for helping to build an understanding of how changes in Earth’s climate are influencing marine life. This video was submitted into the Ocean180 Film Challenge, sponsored by the Florida Center for Ocean Sciences Education Excellence. The video is based on work published in the journal Nature Reviews Microbiology. UPDATE: The video is one of ten finalists! Over 50,000 6–8th grade students will be viewing each video and voting on their favorite. Read more about it in the UH System News.

The University of Hawai‘i at Mānoa reported that it saved $3.4 million on energy costs last year. “When they come to Mānoa, students should know that they are coming to a university that exemplifies solutions to the problems that face us in the 21st century — problems like sustainability and climate change,” said Robert Bley-Vroman, UH Mānoa Chancellor. Over the last eight years, the campus has saved more than nine percent on its projected energy costs by implementing strategic air conditioning, lighting, and building control retrofits. Additionally, UH Mānoa has the state’s first LEED Platinum laboratory facility in the Daniel K. Inouye Center for Microbial Oceanography: Research and Education‘s C-MORE Hale.

Lava flow image The world’s hottest volcanoes

New analysis of satellite observations of 95 of Earth’s most active volcanoes was used to determine which volcanoes on Earth have been the hottest since the turn of the 21st century. The answer depends on how you define hottest, but, in terms of total energy radiated, the prize goes to Kīlauea on Hawai‘i Island. Kīlauea has been in eruption for more than 30 years and spilled lava continuously throughout the study period of 2000–14; flows now threaten the town of Pahoa. Iceland’s ongoing Holuhraun eruption has radiated the most heat for an event. The long-term comparative study was led by Hawai‘i Institute of Geophysics and Planetology (HIGP) assistant researcher Robert Wright and was accepted in Geophysical Research Letters.

“We have actually 41 years of records by now, and we still see a decreasing trend in northeast trade wind frequency,” said Pao-Shin Chu, professor of Atmospheric Sciences and state climatologist, commenting on a follow-up to his 2011 study. The original study published by Chu, a graduate student, and other colleagues gathered wind data from weather stations at four Hawai‘i airports from 1973 to 2009. Four more years of data shows the state’s climate, at least when it comes to prevailing winds, has changed: Honolulu International Airport used to average 200 or more trade days per year, but that has dropped to 150 days or less. Trade winds have shifted more to the east, which may correlate to less rainfall, and increased vog can have negative impacts on tourism, agriculture, and even public health.
