Hawaii 07: Volcanoes Alive!
Learn About Volcanic Activity on an Active Volcano
July 21–27, 2007 TRIP CANCELLED
Join GSA for a specially designed geoscience expedition to the Big Island of Hawaii for an in-depth observation and discussion around the unique geological phenomenon of Hawaii. During your 7-day expedition you will focus on a variety of themes both involving the geological formations of the region and the environmental context of the people and biological communities.
A seamless mix of site-lectures that provide background and field trips that emphasize "hands-on" activities, this program will allow you to spend most of your time outside interacting with the environment. Even transports between sites are designed to allow plenty of time for observation and discussion.
The geology of the Big Island of Hawaii is dominated by Active Volcanism. True, Hawaii Island does display Earth's largest mountain, Mauna Loa, its tallest volcano, Mauna Kea, and the world's most famous active volcano, Kilauea. However, many other geologic features also are displayed on this amazing island. For example, extensive glacial depositsabove 10,000 feet on Mauna Kea represent several stages of Pleistocene glacier development. Huge submarine landslide deposits(Earth's largest) cover major undersea portions of the volcanic mountains and the surrounding seafloor 15,000-18,000 feet below sea level. Above the ocean surface major fault scarpsare visible, especially along the flanks of Mauna Loa and Kilauea. Coral and stony algal growth in the island's warm coastal waters represents incipient reef structures. Sediment erosion, transport and deposition is evident along the shoreline where ocean currents produce volcanic black sand, olivine green sand and coral/algal sand beaches. And, throughout the 500,000 year history of the surface of Hawaii Island, soils have been developing as a result of the interaction of the island's volcanic rock materials with the atmosphere, hydrosphere and biosphere. The result of these many geologic processes is an island that is an ideal geo-science laboratory where geology comes to life.
