Deep origins to the behavior of our volcanoes

Kīlauea volcano, on the Big Island of Hawaii, typically has effusive eruptions, where magma flows to create ropy pāhoehoe lava. But Kīlauea sometimes erupts more violently, showering scoria and blocks over much of the surface of the island. To explain the variability in Kīlauea’s eruption styles, a research team analyzed 25 eruptions that have taken place over the past 600 years. Their research shows that the ultimate fate of a magma at Kīlauea — that is if the eruption will be effusive or explosive — is strongly influenced by the variability in composition of the deep magma. In short, more gas-rich magmas produces more explosive eruptions. “Gas-rich magmas are ‘predisposed’ to rise quickly through the Earth’s mantle and crust and erupt powerfully,” Houghton explained.

Bike Commuting Celebrated on Thursday

This year’s “BikeUHM,” the annual appreciation and promotional event for those who cycle and who are thinking of cycling to UH Mānoa, coincides with the University’s Earth Day Festival on Thursday, April 24. “BikeUHM 2014: Earth Cycles” will be held along Legacy Path (near Dole Street) from 8:00 to 10:00 a.m. To further enhance the cycling experience at UH Mānoa, the University has implemented Sharrow lanes (shared by both motorists and bicyclists) and free bike parking in any of the more than 150 racks positioned around campus. Coming soon is the installation of a secure, enclosed bike shelter in the Lower Campus Parking Structure and bike-share stations on campus, as recommended in a recent feasibility study for bike-sharing in Honolulu.

Windward District’s Science Fair Marks 28th Year

More than 200 students from 31 Windward Oahu schools will present over 160 projects at the annual Windward District’s Science and Engineering Fair. Setup begins today at Windward Community College, with judging tomorrow morning and displays open to the public in the afternoon. Winners will be announced on Saturday. This year marks the event’s 28th year, and the three-day program is organized by vice principals from schools spanning from Waimanalo to Sunset Beach. In addition to the competition, it offers sixth- through tenth-graders several breakout sessions and presentations by college professors as a way to inspire Hawaii’s future scientists. [...]

Sheet metal roses return for Valentine’s Day

The annual “Forever Rose” sale by the Sheet Metal and Plastics Program at HCC started as a bet over 15 years ago. “An apprenticeship student challenged me to make a rose out of sheet metal,” recalls Danny Aiu, Associate Professor of the program. “That night with a strip of sheet metal I molded a rose with my hands. Today, our students apply their skills by operating a plasma cutter, chemicals and other tools used in the trade to create each rose one by one.” [...]

Hawaii lab finds dramatic shift in Pacific ecosystem

The Hawaii Undersea Research Laboratory (HURL) 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 observed overall nitrogen fixation in the North Pacific Ocean has increased by about 20 percent since the mid 1800s and this long-term change appears to be continuing today, according to a study published recently in the journal, Nature. Using chemical information locked in organic skeletal layers, the team used these ancient deep corals as detailed recorders of changes at the base of the open Pacific food web over the last 1,000 years. This represents the first detailed biogeochemical records for the planet’s largest contiguous ecosystem. This type of sample is only available using deep-diving submersibles, such as those operated by HURL. [...]

‘Voice of the Sea’ TV series debuts in January

A new television show highlighting ocean and coastal scientists and cultural experts from Hawaii and the Pacific will debut on January 5, 2014. “Voice of the Sea” will be broadcast on on KVFE (Channel 5 and 1005) on Sundays at 6:00 p.m. The show is hosted by Dr. Kanesa Duncan Seraphin, world paddleboard champion, shark researcher, and science education expert. Dr. Seraphin, director of the University of Hawaii Sea Grant Center of Excellence in Marine Science Education and associate professor at the Curriculum Research & Development Group in the College of Education at the University of Hawaii at Mānoa, has traveled across the Pacific to bring stories of relevance to Hawaii. Each half-hour episode profiles local science and cultural celebrities and presents thought-provoking information in an exciting, original, reality-based way. [...]

Battleship Missouri Screens Special ‘Five-0’ Episode

Starting this Saturday, December 7 through December 13, visitors to the Battleship Missouri Memorial will enjoy a special sneak preview of the ‘Hawaii Five-0’ episode that will later air nationwide on Friday, December 13, 9PM ET/PT, on the CBS Television Network. Titled ‘Ho‘onani Makuakane’ (‘Honor Thy Father’), the episode focuses on the attempted murder of a Pearl Harbor veteran that leads ‘Five-0’ to use decades old evidence to investigate a deadly crime committed within the internment camps holding Americans of Japanese ancestry on Oahu during World War II. A remembrance ceremony using actual World War II veterans was filmed at the Battleship Missouri Memorial. The ‘Hawaii Five-0’ episode in its entirety will be projected onto a large video screen in the Missouri’s educational classroom, which is air-conditioned and located one deck below the main deck next to the Mess Hall.
