Available in PDF, EPUB and Kindle. Book excerpt: The Queen Maud Gulf Migratory Bird Sanctuary in Nunavut, in the central Canadian Arctic, is an important breeding area for a variety of species of waterfowl and other wildlife. An assessment of the types and spatial extent of land cover, with a particular emphasis upon wildlife habitat capability, has not been available for this sanctuary, preventing an adequate environmental assessment of proposed changes to the sanctuary's boundaries and limiting attempts to evaluate population trends and the distribution of wildlife species within the sanctuary. LANDSAT Thematic Mapper satellite imagery and digital image processing technology were used to prepare a land cover map for this large and remote area. Data from an examination of a variety of possible image enhancements, three field seasons of ground and aerial inspections of land cover types, and image classification were used to generate a thematic map of land cover types. An accuracy assessment of the classification provided an estimate of the reliability of the land cover map.

This book was released on 1993 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: On 23 December 1988, the oil barge Nestucca was damaged off Gray's Harbour, Washington and began leaking, spilling about 875,000 litres of Bunker C oil that drifted northwards, leading to widespread oiling of beaches along the coasts of Washington and Vancouver Island and the heavy mortality of seabirds. This report documents the impact of the Nestucca spill on seabirds based on the data collected from British Columbia. The report documented the numbers, types, degree of oiling, and state of decomposition of the birds recovered on Vancouver Island; compared the species composition of the oiled birds with that of offshore and inshore populations wintering off southwest Vancouver Island; estimated the total number of oiled birds to land on Vancouver Island, taking into account the large numbers of carcasses not tallied; estimated the total at-sea mortality represented by the birds recovered on Vancouver Island, taking into account the losses of carcasses at sea; compared the Nestucca victims with normal seabird mortality off Vancouver Island; and assessed the impact of the spill on predatory and scavenging birds on Vancouver Island.
