In 2016, Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated using adaptive resolution imaging sonar (ARIS) at river mile 13.7. Net upstream passage of Chinook salmon greater than or equal to 75 cm as measured by ARIS was estimated to be 6,391 (SE 197) during the early run (16 May–30 June) and 17,447 (SE 403) during the late run (1 July–19 August). Net upstream passage of all Chinook salmon regardless of size was estimated to be 9,851 (SE 355) during the early run and 22,537 (SE 480) during the late run.

Chinook salmon (Oncorhynchus tshawytscha) passage in the Kenai River was estimated from 2017 to 2019 using adaptive resolution imaging sonar (ARIS) at river mile 13.7. Net upstream passage of Chinook salmon greater than or equal to 75 cm as measured each year by ARIS was estimated to be 7,238 (SE = 250), 3,000 (SE = 154), and 4,186 (SE = 160), respectively, during the 2017–2019 early runs (16 May–30 June); and 22,133 (SE = 452), 16,957 (SE = 410), and 11,870 (SE = 310), respectively, during the 2017–2019 late runs (1 July–20 August). Net upstream passage of all Chinook salmon regardless of size was estimated to be 9,696 (SE = 371), 5,390 (SE = 318), and 6,033 (SE = 285), respectively, during the 2017–2019 early runs; and 24,436 (SE = 423), 25,143 (SE = 654), and 18,093 (SE = 547), respectively, during the 2017–2019 late runs.

In 2015, Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated using Adaptive Resolution Imaging Sonar (ARIS) at river mile 13.7. Net upstream passage of Chinook salmon greater than or equal to 75 cm as measured by ARIS was estimated to be 4,212 (SE 168) during the early run (16 May-30 June) and 17,687 (SE 377) during the late run (1 July-20 August). Net upstream passage of all Chinook salmon regardless of size was estimated to be 7,332 (SE 312) during the early run and 28,918 (SE 703) during the late run.

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.

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.

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.

Adaptive resolution imaging sonar (ARIS) was used for the first time in 2018 to estimate the abundance of late-run Chinook salmon (Oncorhynchus tshawytscha) at river mile (RM) 8 of the Kasilof River. The same methods were used to estimate late-run Chinook salmon abundance in 2019 and 2020. In 2019, the sonar was operated from 15 June through 31 August. In 2020, the sonar was operated from 15 June through 22 August. Net upstream passage of late-run Chinook salmon greater than or equal to 75 cm mid eye to tail fork length (METF) as measured by ARIS was estimated to be 4,507 (SE = 184) in 2019 and 3,388 (SE = 165) in 2020. The 2019 cumulative late-run Chinook salmon abundance estimate of fish greater than or equal to 75 cm METF was higher than the 2018 and 2020 estimates. Run timing in 2019 and 2020 was earlier than in 2018.

The Colli Albani Volcano contains 21 scientific contributions on stratigraphy, volcanotectonics, geochronology, petrography and geochemistry, hydrogeology, volcanic hazards, geophysics and archaeology, and a new 1:50 000 scale geological map of the volcano. The proximity to Rome and the interconnection between volcanic and human history also make this volcano of interest for both specialists and non-specialists.
