Undergrad helps discover new bacterium on way to marine biology degree

Terasakiispira papahanaumokuakeensis, spiral-shaped bacterium grown from a pond on the Pearl and Hermes Atoll in the Northwestern Hawaiian Islands.

A UH Mānoa undergraduate who conducted a research project on her way to earning a bachelor of science degree in 2014 in marine biology was instrumental in the discovery of a spiral-shaped bacterium that is the only known representative of a new genus and species. Vanessa K. Zepeda, 30, is the lead author of a paper published in the current ...

Historically when El Niño events occur, Hawaiʻi has experienced nearly six months of drought, from November to April. Conversely, during La Niña events rainfall has been greater than normal, building up Hawaiʻi’s groundwater supply. New research published this month in the Journal of Climate by scientists at the University of Hawaiʻi at Mānoa, Nanjing University of Information Science and Technology ...

Just below Earth’s surface, beneath the roots and soil, is a hard, dense layer of bedrock that is the foundation for all life on land. Cracks and fissures within bedrock provide pathways for air and water, which chemically react to break up rock, ultimately creating soil—an essential ingredient for all terrestrial organisms. This weathering of bedrock is fundamental to life ...

A paper published this month by University of Hawaiʻi and Hawaiian Volcano Observatory researchers in the Bulletin of the American Meteorological Society details the development and utility of a computer model for the dispersion of volcanic smog or “vog,” which forms when volcanic sulfur dioxide gas interacts with water and coverts it to acid sulfate aerosol particles in the atmosphere. ...

Rapidly acidifying waters pose major threat for Southern Ocean ecosystem

manoa-marine-acidification_cropped

As a result of increasing atmospheric carbon dioxide concentrations, the chemistry of the Southern Ocean is expected to change so fast over the next few decades that tiny creatures at the base of the food web may soon struggle to form their shells. New research by scientists from the University of Hawaiʻi at Mānoa and the University of Alaska, Fairbanks ...
