Book Description
Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated in 2014 at RM 8.6 using dual-frequency identification sonar (DIDSON). Estimates of midriver Chinook salmon passage between and at least 3 m from the transducers were 4,862 (SE 338) fish for the early run (16 May-30 June) and 13,952 (SE 492) fish for the late run (1 July-15 August). Methods and result from a second experimental sonar site located above tidal influence at RM 13.7 are presented in a separate report.

Book Description
Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated in 2013 at RM 8.6 using dual-frequency identification sonar (DIDSON). Estimates of midriver Chinook salmon passage between and at least 3 m from the transducers were 1,439 (SE 138) fish for the early run (16 May-30 June) and 15,185 (SE 566) fish for the late run (1 July-15 August). The early-run estimate is too small to explain weir counts at upriver tributaries. Methods and results from a second experimental sonar site located above tidal influence at RM 13.7 are presented in a separate report.

Book Description
This is the first book on the climate and Quaternary geology of Novaya Zemlya since 1924. This volume also presents the results of a search for sixteenth century navigator Willem Barents along Novaya Zemlya's northern shores, and a synopsis of the exploration of the region after the "Little Ice Age." Appendices and tables summarize the occurrence of bird species and reindeer, as well as the spread of radioisotope contaminants following nuclear weapons tests since 1954. This title is a Rozenberg Publishers title.

Book Description
The fields of fish population dynamics and stock assessment have seen major advances in the 1980s and 1990s, creating the need for a new synthesis. This text attempts that synthesis by presenting a contemporary approach for quantitative fisheries science that incorporates modern statistical and mathematical techniques. It emphasizes the link between biology and theory by explaining the assumptions inherent in the quantitative methods and models. The book covers key topics that are often overlooked in other texts, such as optimal harvesting, migratory stocks, and complex age and size-structured models. Quantitative Fish Dynamics is an ideal textbook for graduate and undergraduate courses in fish population dynamics and stock assessment. It is an indispensable reference work for fisheries scientists and others interested in conservation biology, fish and wildlife management, population ecology, and statistical applications.

Book Description
Broadening its scope to nonstatisticians, Bayesian Methods for Data Analysis, Third Edition provides an accessible introduction to the foundations and applications of Bayesian analysis. Along with a complete reorganization of the material, this edition concentrates more on hierarchical Bayesian modeling as implemented via Markov chain Monte Carlo (MCMC) methods and related data analytic techniques. New to the Third Edition New data examples, corresponding R and WinBUGS code, and homework problems Explicit descriptions and illustrations of hierarchical modeling—now commonplace in Bayesian data analysis A new chapter on Bayesian design that emphasizes Bayesian clinical trials A completely revised and expanded section on ranking and histogram estimation A new case study on infectious disease modeling and the 1918 flu epidemic A solutions manual for qualifying instructors that contains solutions, computer code, and associated output for every homework problem—available both electronically and in print Ideal for Anyone Performing Statistical Analyses Focusing on applications from biostatistics, epidemiology, and medicine, this text builds on the popularity of its predecessors by making it suitable for even more practitioners and students.

Book Description
In 2013, Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated using Adaptive Resolution Imaging Sonar (ARIS) at a newly established site at river mile 13.7. Medium and large Chinook salmon (greater than or equal to 75 cm as measured by ARIS) were directly assessed by the sonar, yielding net upstream passage estimates of 1,724 (SE 93) during the early run (17 May-30 June) and 12,656 (SE 282) during the late run (1 July-17 August). Smaller Chinook salmon (less than 75 cm ARIS length) overlap in size with other species; thus a combination of sonar, netting, telemetry, and weir data from this and other projects are required for assessing the abundance of all Kenai River Chinook salmon regardless of size. During the 2013 early run, telemetry and weir data were used to obtain a net upstream passage estimate of 2,806 (SE 341) small Chinook salmon; this estimate was combined with the ARIS estimate of medium and large Chinook salmon for a total of 4,530 (SE 353) Chinook salmon regardless of size. During the late run, a mixture model was fitted to sonar and netting data to obtain a net upstream passage estimate of 19,373 (SE 583) Chinook salmon regardless of size.

Book Description
Alaska Department of Fish and Game (ADF&G) has monitored Chinook salmon (Oncorhynchus tshawytscha) passage in the Kenai River using side-looking sonar technology from 1987 to present. The historical site at RM 8.6 used dual-beam (1987–1994), split-beam (1995–2011), and dual-frequency identification sonar or “DIDSON” (2012–2014) technology. Starting in 2013, ADF&G began operating adaptive resolution imaging sonar or “ARIS” at a new site located at RM 13.7. The RM 8.6 site was discontinued following the 2014 season in favor of data collection at the RM 13.7 site. This plan covers RM 13.7 project operations for the 2020–2022 seasons.
