Book Arctic Report Card 2010

Download or read book Arctic Report Card 2010 written by Jacqueline A. Richter-Menge and published by DIANE Publishing. This book was released on 2011-08 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tracks recent environ. changes throughout the Arctic. In 2010, it is clear that the Arctic is experiencing the impacts of a prolonged and amplified warming trend, highlighted with many record-setting events. The impact of this warming is most evident in the dramatic losses that have been observed in the ice covers that define the region. Since the loss of these ice covers serves to further feed the warming trend, the expectation is that warming will continue. This makes it increasingly unlikely that the Arctic will return to conditions that were considered normal in the later part of the 20th cent. Instead, it is very likely that Arctic climate warming will continue and records will continue to be set in years to come. Charts and tables. This is a print on demand report.

Book An Estimate of the Western Hudson Bay Beluga Population Size in 2004

Download or read book An Estimate of the Western Hudson Bay Beluga Population Size in 2004 written by and published by . This book was released on 2005 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents findings of aerial surveys of belugas that were flown in western & southern Hudson Bay between July 29 and August 6, 2004. A combination of aerial visual line-transect surveys and photographic surveys were used to estimate the numbers of belugas present in that region. These estimates were corrected for availability bias based on a correction factor obtained from a target experiment and beluga surfacing observations conducted in the similarly-silted waters of the St. Lawrence. These aerial surveys have allowed production of a most conservative estimate for this population, represented by the sum of the estimates of the Churchill-Seal and Nelson areas, and rounded to the nearest hundred.
