Book Description
Adaptive resolution imaging sonars (ARIS) are used to produce inriver abundance estimates of Kenai River early- and late-run Chinook salmon Onchorhynchus tshawytscha and Kasilof River late-run Chinook salmon. These sonars can be used to produce inseason estimates of fish 75 cm mid eye to tail fork length (METF) or longer, and when used over the entire run, can be used in conjunction with test fish data to produce postseason abundance estimates of all Chinook salmon regardless of size. Sonar estimates of Chinook salmon inriver passage provide the basis for estimating spawning escapement and implementing management plans that regulate harvest in the competing fisheries for these stocks.

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
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 at historical (1987–2012) and modern (2013–present) sites and with multiple updated sonar technologies. Starting in 2018, a similar sonar program to monitor Chinook salmon at the nearby Kasilof River was begun as well. This plan covers sonar project operations at Kenai RM 13.7 and Kasilof RM 8 for the 2023–2025 seasons with the goal of producing daily inseason net passage estimates of fish 75 cm or longer for the Kenai River and postseason net upstream passage estimates of fish 75 cm or longer for the Kasilof river.

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
DEDICATED TO THE NEXT GENERATION OF WOMEN BOARD LEADERSIn 2018, California passed a senate bill (SB 826) to require publicly held companies headquartered in CA to have at least one woman on their board by 2020. In 2020, Nasdaq proposed a mandate that would require listed companies to have at least two diverse board members with one member who identifies as female. Initiatives like these are helping advance gender parity on boards in many regions, not just the U.S. In late 2020, women held 22.6% of the board seats on the Russell 3000 for the first time, a 6.5 point jump over the past 4 years.Zooming out to the global scale, the picture is similarly improving. In 2020, about 23% of board seats globally were held by women, compared to 20% in 2018. Yet...at the time of this writing, 10% of large global companies do not have a single woman on their board. And the percent of women who chair boards is dramatically smaller. Among the largest 500 public U.S. companies by revenue the share of women who chaired boards remained stagnant at 7.4%. Notably, of those women who chair boards, few of them use the term Chairwoman in their bios or LinkedIn profiles-opting for monikers Chairman, or Board Chair, or occasionally Chairperson. This book features the extraordinary voices and stories of women leaders from around the world who have trailblazed to the board room, as letters to the next generation of women in business and government. With the salutation "Dear Chairwoman," these letters are infused with the energy to inspire young women to both pursue board governance early, and to claim the 'Chairwoman' title in taking the senior-most seat in the Board Room.

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
