Hawaii's main volcano chains--the Loa and Kea trends--have distinct sources of magma and unique plumbing systems connecting them to the Earth’s deep mantle, according to UBC research published this week in Nature Geoscience.

Boulders deposited by an ancient glacier that once covered the summit of Mauna Kea on the island of Hawaii have provided more evidence of the extraordinary power and reach of global change, particularly the slowdown of a North Atlantic Ocean current system that could happen again and continues to be a concern to climate scientists.

Underwater canyons have long been considered important habitats for marine life, but until recently, only canyons on continental margins had been intensively studied.

Tropical Storm Hilda is hanging on to tropical storm force winds, and continues to track south of the Hawaiian Islands.

Tropical Storm Felicia is closing in on the Hawaiian Island chain and its center is now expected to pass just north of the big island before moving through the islands Tuesday and Wednesday.
