Dead men walking: search and rescue in US National Parks.
OBJECTIVE To identify search and rescue (SAR) trends in US National Park Service (NPS) units. METHODS A retrospective review of the US National Park Service Annual Search and Rescue Reports from 1992 to 2007 and the SAR statistics for all NPS units in 2005. RESULTS From 1992 to 2007 there were 78,488 individuals involved in 65,439 SAR incidents. These incidents ended with 2659 fatalities, 2...
متن کاملMonitoring the condition of natural resources in US national parks.
The National Park Service has developed a long-term ecological monitoring program for 32 ecoregional networks containing more than 270 parks with significant natural resources. The monitoring program assists park managers in developing a broad-based understanding of the status and trends of park resources as a basis for making decisions and working with other agencies and the public for the lon...
متن کاملAnthropogenic and natural sources of ambient noise in the ocean
Ocean ambient noise results from both anthropogenic and natural sources. Different noise sources are dominant in each of 3 frequency bands: low (10 to 500 Hz), medium (500 Hz to 25 kHz) and high (>25 kHz). The low-frequency band is dominated by anthropogenic sources: primarily, commercial shipping and, secondarily, seismic exploration. Shipping and seismic sources contribute to ambient noise ac...
متن کاملAcoustic correlated sources direction finding in the presence of unknown spatial correlation noise
In this paper, a new method is proposed for DOA estimation of correlated acoustic signals, in the presence of unknown spatial correlation noise. By generating a matrix from the signal subspace with the Hankel-SVD method, the correlated resource information is extracted from each eigen-vector. Then a joint-diagonalization structure is constructed of the signal subspace and basis it, independent...

Piekie U.S. National Park Service land managers face a variety of challenges to preserving the biodiversity in their parks. A principle challenge is to minimize the impacts of surrounding land use on park c...
