Geologic resource evaluation of Pu‘ukoholā Heiau National Historic Site, Hawai‘i, part II: Benthic habitat mapping Geologic resource evaluation of Pu‘ukoholā Heiau National Historic Site, Hawai‘i, part II: Benthic habitat mapping
In cooperation with the U.S. National Park Service (NPS), the U.S. Geological Survey (USGS) has mapped the underwater environment in and adjacent to three parks along the Kona coast on the island of Hawai‘i. This report is the second of two produced for the NPS on the geologic resource evaluation of Pu‘ukoholā Heiau National Historic Site (PUHE) and presents benthic habitat mapping of...

Coastal evolution and sediment budget at the mouth of the Columbia River, USA Coastal evolution and sediment budget at the mouth of the Columbia River, USA
The coastal morphology of the Mouth of the Columbia River (MCR) has changed dramatically over the past century. Since the construction of jetties in 1914 and 1917, the inlet deepened and stabilized, the outer ebb delta migrated northward and offshore several kilometers, and the adjacent shorelines to the north and south prograded several hundreds of meters. Recently, high rates of...

Hawaii Beach Monitoring Program: Profile locations Hawaii Beach Monitoring Program: Profile locations
Coastal erosion is widespread and locally severe in Hawaii and other low-latitude areas. Typical erosion rates in Hawaii are in the range of 15 to 30 cm/yr (0.5 to 1 ft/yr; Hwang, 1981; Sea Engineering, Inc., 1988; Makai Ocean Engineering, Inc. and Sea Engineering, Inc.,1991). Recent studies on Oahu (Fletcher et al., 1997; Coyne et al., 1996) have shown that nearly 24%, or 27.5 km (17.1...

Bathymetric change off the Washington-Oregon coast Bathymetric change off the Washington-Oregon coast
Historical hydrographic data from the Washington/Oregon shelf are compared for the first time to identify bathymetric change on a regional scale. Offshore data sets exist for four time periods: 1800s, pre-1950s, post-1950s, and 1990s. Data from only two time periods, 1868-87 and 1926-27, cover the entire offshore region between Tillamook Head, Oregon and Grays Harbor, Washington. A...
