Evaluation of an Unmanned Airborne System for Monitoring Marine Mammals (2009, background): “…1994; Harwood et al., 1996; Forney & Barlow, 1998; Bengtson et al., 2005) and ships (e.g., Cattanach et al., 1993; Barlow, 1995; Swartz et al., 2003; Barlow & Forney, 2007) have been the primary platforms for documenting the distribution and abundance of marine mammals over broad geographic areas.”
Inferring trackline detection probabilities, g(0), for cetaceans from apparent densities in different survey conditions (2015, methodology): “Barlow and Forney (2007) estimated g(0) for large whales in the U.S. West Coast study area to be approximately 0.92 (CV = 0.02) using a conditionally independent observer method developed by Barlow (1995) and applied to Beaufort sea states 0–5.”
Marine Vertebrate Biodiversity and Distribution Within the Central California Current Using Environmental DNA (eDNA) Metabarcoding and Ecosystem Surveys (2019, background): “The traditional surveys have not been designed to detect some of the organisms that are detected by eDNA (e.g., large bony fish), as some taxa may evade the trawl net or are difficult to assess via the marine mammal survey [e.g., beaked whales and small porpoises (Barlow and Forney, 2007)].”
Fin Whale: Balaenoptera physalus (2009, background): “The best estimate of fin whale abundance in California, Oregon, and Washington waters out to 300 nmi is the geometric mean of line transect estimates from summer/autumn ship surveys conducted in 2001 ( Barlow and Forney 2007 ) and 2005 (Forney 2007), or 2,636 (CV = 0.15) whales.”
Habitat-based spatial models of cetacean density in the eastern Pacific Ocean (2012, methodology): “…not permitted without written consent of the publisher Endang Species Res 16: 113–133, 2012 Hammond et al. 2002, Stevick et al. 2003, Gerrodette & Forcada 2005, Barlow & Forney 2007) across broad geographic areas, such as waters within the United States Exclusive Economic Zone off California,…”
