Download or read book Summer, Fall, and Early Winter Behavior of Beluga Whales, Delphinapterus Leucas, Satellite-tagged in Cook Inlet, Alaska, in 1999 and 2000 written by Kristin L. Laidre and published by . This book was released on 2017 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The following report contains detailed information on the movement patterns of beluga whales that were satellite-tagged in 1999 and 2000 in Cook Inlet, Alaska. The seasonal movements and dive patterns of three whales CI-9901, CI-0001, and CI-0002 were analyzed, and movement data from the whales tagged in 2000 were referenced to in a subsequent paper by Hobbs et al. (2005). However, the detailed analyses of diving behavior and movement patterns of these individual whales were never made available until now. The seasonal movements and dive patterns of three belugas in Cook Inlet, Alaska, were monitored between June and January 1999-2000 using satellite telemetry. One adult male whale was tagged on 30 May 1999 and tracked until 16 September 1999 (109 days), and one juvenile female and one adult male were tagged on 13 September 2000 and tracked until 2 (115 days) and 18 January 2001 (124 days), respectively. Whales remained in the inlet the entire time they were tracked. Mean dive depths across the entire tracking period ranged from 2.6 m (SD = 5.2) to 5.2 m (SD = 8.8). Mean dive durations ranged from 1.4 minutes (SD = 2.0) to 3.1 minutes (SD = 4.1). Overall mean time at surface (between 0 and 1 m) ranged from 23% to 70% and appeared to be related to season and location. Behavioral periods were identified for each whale (4-60 days) based on stationary movements in a particular part of the inlet and unique diving behavior during that time. Significant differences were found between diving behavior and tidal rate of change and direction, as well as whale location and average sea-ice concentration. Belugas in Cook Inlet display seasonal variation in dive behavior and movement patterns, both of which have implications for sightings rates, correction factors, and abundance estimates obtained for the population.

Download or read book Aerial Surveys, Abundance, and Distribution of Beluga Whales (Delphinapterus Leucas) in Cook Inlet, Alaska, June 2016 written by Kim E. W. Shelden and published by . This book was released on 2017 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Marine Fisheries Service (NMFS) has conducted aerial surveys to estimate abundance of the beluga population in Cook Inlet, Alaska, each June, July, or both from 1993 to 2012, after which biennial surveys began in 2014. The current document presents survey results and subsequent analyses yielding an abundance estimate and population trend based on data collected during June 2016. Surveys occurred May 31 - June 9, 2016 (49.2 flight hours). All surveys were flown in twin-engine, high-wing aircraft (i.e., an Aero Commander) at a target altitude of 244 m (800 ft) and speed of 185 km/hour (100 knots), consistent with NMFS' surveys of Cook Inlet conducted in previous years. Tracklines were flown 1.4 km from the shoreline, along the entire Cook Inlet coast, including islands. Additionally, sawtooth pattern tracklines were flown across the inlet in 2016. These aerial surveys effectively covered 40% of the total surface area of Cook Inlet and 100% of the coastline. In particular, most of the upper inlet, north of the East and West Foreland where beluga whales are consistently found, was surveyed seven times (out of seven attempts). Paired, independent observers searched on the coastal side of the plane, where most beluga sightings occur, while a single observer searched on the inlet side. A computer operator/data recorder periodically monitored distance from the shoreline (1.4 km) with a clinometer (angle 10°). After finding beluga groups, a series of aerial passes allowed all observers to each make independent counts of every group. In addition, whale groups were video recorded for later analysis and more precise counts in the laboratory. [doi:10.7289/V5/AFSC-PR-2017-09 (https://doi.org/10.7289/V5/AFSC-PR-2017-09)]

Available in PDF, EPUB and Kindle. Book excerpt: Limited information exists on the foraging behavior of the endangered population of beluga whales (Delphinapterus leucas) in Cook Inlet, Alaska, especially during the winter months with heavy ice-cover. We used satellite telemetry to record the movement (n = 14) and diving (n = 11) behavior of whales across 3 years (1999-2003), including the winter months. Whales remained in Cook Inlet the entire time they were tracked. Mean dive depths across the entire tracking period ranged from 1.6 (SD ± 2.1) to 6.7 (SD ± 10.4) m and mean dive duration ranged from 1.1 (SD ± 1.3) to 6.9 (SD ± 9.5) minutes. Overall, dives were significantly shorter in the near-shore areas of Chickaloon Bay, Susitna Delta, Knik Arm, Turnagain Arm, and Trading Bay. This type of dive behavior, in combination with significantly slower transit rates suggests that whales are likely foraging in these areas. While belugas tended to prefer shallow inshore waters throughout the year, the presence of sea ice between December and May may prevent access to coastal areas. Preference for pack ice, despite the large proportions of Cook Inlet remaining ice-free, may be an indication of belugas attempting to access coastal areas despite increased ice concentration. With the declining abundance of Cook Inlet belugas, identifying potential foraging areas during ice-covered and ice-free periods is critical to the recovery of this endangered population.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past several years, many investigators interested in the effects of man-made sounds on animals have come to realize that there is much to gain from studying the broader literature on hearing sound and the effects of sound as well as data from the effects on humans. It has also become clear that knowledge of the effects of sound on one group of animals (e.g., birds or frogs) can guide studies on other groups (e.g., marine mammals or fishes) and that a review of all such studies together would be very useful to get a better understanding of the general principles and underlying cochlear and cognitive mechanisms that explain damage, disturbance, and deterrence across taxa. The purpose of this volume, then, is to provide a comprehensive review of the effects of man-made sounds on animals, with the goal of fulfilling two major needs. First, it was thought to be important to bring together data on sound and bioacoustics that have implications across all taxa (including humans) so that such information is generally available to the community of scholars interested in the effects of sound. This is done in Chaps. 2-5. Second, in Chaps. 6-10, the volume brings together what is known about the effects of sound on diverse vertebrate taxa so that investigators with interests in specific groups can learn from the data and experimental approaches from other species. Put another way, having an overview of the similarities and discrepancies among various animal groups and insight into the “how and why” will benefit the overall conceptual understanding, applications in society, and all future research.
