Crops close to small water bodies may exhibit changes in yield if the water mass causes significant changes in the microclimate of areas near the reservoir shoreline. The scientific literature describes this effect as occurring gradually, with higher intensity in the sites near the shoreline and decreasing intensity with distance from the reservoir. Experiments with two soybean cultivars were c...

4 Humans are increasingly altering the Earth’s surface, and affecting processes that shape and 5 reshape landscapes. In many cases, humans are reacting to landscape-change processes that 6 represent natural hazards. Thus, the landscape is reacting to humans who are reacting to the 7 landscape. When the timescales for landscape change are comparable to those of human 8 dynamics, human and ‘natur...

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...

Shorelines are critical information in a Coastal Geographic Information System (CGIS). Shorelines have a dynamic nature. Hence, their definition, mapping, and subsequent utilization are a more complicated issue than people usually think. Different approaches to shoreline mapping are described and analyzed in this paper. In particular, a new method is presented in which tide-coordinated shorelin...

BACKGROUND Ecosystem management requires organizing, synthesizing, and projecting information at a large scale while simultaneously addressing public interests, dynamic ecological properties, and a continuum of physicochemical conditions. We compared the impacts of seven water level management plans for Lake Ontario on a set of environmental attributes of public relevance. METHODOLOGY AND FIN...
