Factors affecting aerial surveys of marine fauna, and their relationship to a census of dugongs in the coastal waters of the Northern Territory.
Austral. Wildl. Res. 13(1): 27-37. 5 tabs. 3 figs.
–Reports on experiments to determine the effects on survey results of environmental conditions and survey techniques, and to derive correction factors. A dugong census of the Northern Territory, Australia, between the Daly River and Millingimbi in December 1983 yielded a minimum estimate of 2593 ± 530 and a total population estimate of 38,000, the highest densities being associated with shallow and sheltered waters.

Seasonal distribution and abundance of dugongs in the western Gulf of Carpentaria.
Austral. Wildl. Res. 16(2): 141-149. 5 tabs. 4 figs.
–Aerial surveys in 1984-85 showed no major seasonal changes in distribution and relative abundance. Mimimum population sizes of 16,816ñ2946 (dry season) and 16,846ñ3257 (wet season) were calculated. Abundance was correlated with area of available seagrass beds. Catch rate by Aboriginal hunters declined from about 60 to 10 per year between the 1960s and 1985, possibly due to excessive hunting, but the present harvest rate appears to be sustainable.
