Phuket, the study area of this work with 33 sandy beaches, provides about 15% nation’s gross domestic product from tourism industry. Many factors cause shoreline changes affecting beach areas, such as seasonal erosion and rising sea levels. In study, position was key parameter for evaluating changes. The CoastSat open-source software selected to analyze using a publicly available satellite imag...

In this study, we analyze the influence of Great East Japan Earthquake, which occurred on 11 March 2011, shoreline northern Ibaraki Coast. After earthquake, area experienced subsidence approximately 0.4 m. Shoreline changes at eight sandy beaches along coast are estimated using various satellite images, including ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer), ALOS AVNIR...

Shoreline mapping and shoreline change detection are critical in many coastal zone applications. This paper presents results of the semi-automatic mapping of a coastal area of Lake Erie using 4-meter resolution multispectral (XS) and 1-meter resolution panchromatic (Pan) IKONOS Geo stereo images. An overview of the geometric processing of IKONOS imagery is presented. Then, the latest results of...

Barrier islands of Northwest Florida were heavily oiled during the Deepwater Horizon spill, but less is known about the impacts to the shorelines of the associated estuaries. Shoreline sediment oiling was investigated at 18 sites within the Pensacola Bay, Florida system prior to impact, during peak oiling, and post-wellhead capping. Only two locations closest to the Gulf of Mexico had elevated ...

Much of the protected habitat available to the threatened Marbled Murrelet Brachyramphus marmoratus and other old-growth associated species in the Pacific Northwest is in narrow strips along the coast (e.g., parks and scenic fringes). Using data over two years from three watersheds on southwest Vancouver Island, we show that such shoreline strip forests represent suboptimal habitat for murrelet...

In July 1999, California's ocean recreational bacterial water quality standards were changed from a total coliform (TC) test to a standard requiring testing for all three bacterial indicators: TC, fecal coliforms (FC), and enterococci (EC). To compare the relationship between the bacterial indicators, and the effect that changing the standards would have on recreational water regulatory actions...
