CTAHR Cooperative Extension Service convenes the Hawai‘i Extension Climate Forum

Pacific islands contribute less that 0.03 percent of global greenhouse gas emissions, yet they suffer some of the greatest threats of climate change. This was a central point made at the Hawaiʻi Extension Climate Forum, an event organized last month by faculty and staff of the College of Tropical Agriculture and Human Resources (CTAHR). The forum brought together other university and community partners addressing …

Biodiversity loss from deep-sea mining will be unavoidable

Biodiversity losses from deep-sea mining are unavoidable and possibly irrevocable, an international team of 15 marine scientists, resource economists and legal scholars argue in a letter published recently in the journal Nature Geoscience. The experts, including Craig Smith, oceanography professor at the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST), say the International Seabed …

Reptile skin grown in lab for first time, helps study endangered turtle disease

Scientists, including Tina Weatherby with the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST), published a study wherein they reconstructed the skin of endangered green turtles, marking the first time that reptile skin was successfully engineered in a laboratory. In turn, the scientists were able to grow a tumor-associated virus to better understand certain …

UH researchers help community understand and prepare for king tides

Researchers from the University of Hawaiʻi at Mānoa were out in force again this month to document and study the king tides that occurred on June 23 and 24. The water level along the coast, already expected to inundate nearshore areas with the some of the highest annual tides was enhanced by elevated water levels and a large south swell …

New wave buoy off Pearl Harbor to measure ocean conditions

On June 6, the Pacific Islands Ocean Observing System (PacIOOS) deployed a new wave buoy near the entrance to Pearl Harbor, approximately 1.5 miles offshore. The wave buoy provides accurate information on wave height, direction and period, and also measures surface currents and sea surface temperature. Wave buoy data benefit the entire community and are important to make well-informed and …

New evidence reveals source of 1586 Sanriku, Japan tsunami

A team of researchers, led by Rhett Butler, geophysicist at the University of Hawaiʻi at Mānoa, re-examined historical evidence around the Pacific and discovered the origin of the tsunami that hit Sanriku, Japan in 1586—a mega-earthquake from the Aleutian Islands that broadly impacted the north Pacific. Until now, this was considered an orphan tsunami, a historical tsunami without an obvious …
