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.

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.

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.

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
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.

The United States Coast Pilot consists of a series of nautical books that cover a variety of information important to navigators of coastal and intracoastal waters and the Great Lakes. Issued in nine volumes, they contain supplemental information that is difficult to portray on a nautical chart. Topics in the Coast Pilot include channel descriptions, anchorages, bridge and cable clearances, currents, tide and water levels, prominent features, pilotage, towage, weather, ice conditions, wharf descriptions, dangers, routes, traffic separation schemes, small-craft facilities, and Federal regulations applicable to navigation. Coast Pilot 1 covers the coasts of Maine, New Hampshire, and part of Massachusetts, from West Quoddy Head in Maine to Provincetown in Massachusetts. Major ports are at Portsmouth, NH and Boston, MA. Coast Pilot 2 covers the Atlantic coast from Cape Cod to Sandy Hook, embracing part of the Massachusetts coast and all of the coasts of Rhode Island, Connecticut, and New York. Coast Pilot 3 covers the Atlantic coast from Sandy Hook to Cape Henry, including the New Jersey Coast, Delaware Bay, Philadelphia, the Delaware - Maryland - Virginia coast, and the Chesapeake Bay. Coast Pilot 4 covers the Atlantic coast of the United States from Cape Henry to Key West. Coast Pilot 5 covers the Gulf of Mexico from Key West, FL to the Rio Grande. Also covers Puerto Rico and the Virgin Islands. Coast Pilot 6 covers the Great Lakes system, including Lakes Ontario, Erie, Huron, Michigan, and Superior, their connecting waters, and the St. Lawrence River. Coast Pilot 7 covers the rugged United States coast of California, Oregon and Washington, between Mexico on the south and Canadas British Columbia on the north. Coast Pilot 7 also includes Hawaii and other United States territories in the South Pacific. Coast Pilot 8 covers the panhandle section of Alaska between the south boundary and Cape Spencer. In this volume, general ocean coastline is only 250 nautical miles, but tidal shoreline totals 11,085 miles. Coast Pilot 9 deals with the Pacific and Arctic coasts of Alaska from Cape Spencer to the Beaufort Sea. General ocean coastline totals 5,520 nautical miles, and tidal shoreline totals 18,377 miles. Coast Pilot 10 consists of excerpts taken from other coast pilots with reference to the Intercoastal Waterway

Book Description
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.
