On November 13, 2015, the Hawaii Shore and Beach Preservation Association held our 2015 annual members meeting at the University of Hawaii. The meeting focused on the planning and administration of the organization and included reports from our Chapter Committees which include: Legislative, Membership Outreach, Workshop/Conference, and Elections. The meeting included a very informative presentation from HSBPA Board Member, Chuck Blay, PhD (TEOK Investigations, Kauai).
Character and Origin of the Beaches of Hawaii Island: The Big Island’s Geologic Youthfulness and Climate
The geologically very young Big Island of Hawaii constitutes 63% of the archipelago’s land area, yet its 500 km perimeter possesses less than 5% of the island chain’s sandy beaches. Many of the island’s unique black, green and white sandy beaches are famous on a global scale. However, they merely represent sedimentary products resulting from unique combinations of normal geological processes. Quantitative petrographic analyses of the diverse coastal deposits document the controlling aspects of the high volcanic island’s youthful geologic complexity in combination with its trade wind-dominated climatic setting.
