The National Marine Fisheries Service (NMFS) has conducted aerial surveys of the beluga population in Cook Inlet, Alaska, each June and/or July since 1993. Results from 1993 to 2000 were published in Rugh et al. The current document is a collection of field reports for the subsequent years, from 2001 to 2004. Surveys were done 5-12 June 2001 (55 flight hours; 29.3 hours good effort), 4-11 June 2002 (45 flight hours; 24.4 hours good effort), 31 May - 12 June 2003 (61 flight hours; 30.5 hours good effort), and 2-9 June 2004 (45 flight hours; 19.0 hours good effort). All surveys were flown in an Aero Commander (twin-engine, high-wing aircraft) at a target altitude of 244 m (800 ft) and speed of 185 km/hour (100 knots), consistent with previous surveys.
