I'd like to announce the recent publication of the following paper:


Daniel R. Zeh, Michelle R. Heupel, Colin J. Limpus, Mark Hamann, Mariana
M.P.B. Fuentes, Russel C. Babcock, Richard D. Pillans, Kathy A. Townsend,
Helene Marsh. Is acoustic tracking appropriate for air-breathing marine
animals? Dugongs as a case study, Journal of Experimental Marine Biology and
Ecology, Volume 464, March 2015, Pages 1-10, ISSN 0022-0981,


Marine animals face increased pressure through expanded shipping and
recreational activities. Effective conservation and management of large
species like marine mammals or sea turtles depend on knowledge of movement
and habitat use. Previous studies have used data collected from either
satellite or acoustic telemetry but rarely both. In this study, data from
satellite and acoustic technologies were used to: determine the efficacy of
satellite and acoustic telemetry to define dugong movement patterns; compare
the benefits and limitations of each approach; examine the costs of each
approach in relation to the amount and type of data provided; and relate
telemetry data to the boundaries of a Go Slow area designed to protect
dugongs and turtles from vessel strike within an urbanised coastal embayment
(Moreton Bay, Queensland, Australia). Twenty-one dugongs were captured in
seagrass habitats on the Eastern Banks of Moreton Bay in July-September 2012
and July 2013 and fitted with GPS and acoustic transmitters. Both satellite
and acoustic telemetry produced reliable presence and movement data for
individual dugongs. When the dugongs were within the range of the acoustic
array, there was relatively good correspondence between the overall space
use measures derived from GPS and acoustic transmitters, demonstrating that
acoustic tracking is a potentially valuable and cost-effective tool for
monitoring local dugong habitat use in environments equipped with acoustic
receiver arrays. Acoustic technology may be particularly useful for species
that establish home ranges with stable residency especially near large urban
or port environs. However, the relative merits of the two technologies
depend on the research question in the context of the species of interest,
the location of the study and whether the study site has an established
acoustic array.
