Cetacean sightings and acoustic detections in the offshore waters
The Indian Ocean Sanctuary was established in 1979 in an effort to allow exploited stocks of whales to recover from whaling and to facilitate benign research. Further information is required to establish comprehensive management and conservation measures for species within these waters. The current study took place in the offshore waters of Sri Lanka in early 2003. During three research cruises...
متن کاملMarine Seismic Surveys — a Study of Environmental Implications
An experimental program was run by the Centre for Marine Science and Technology of Curtin University between March 1996 and October 1999 to study the environmental implications of offshore seismic survey noise. This work was initiated and sponsored by the Australian Petroleum Production and Exploration Association. The program: • characterised air gun signal measurements; modelled air gun array...
متن کاملModelling heterogeneity in cetacean surveys
Methods for improving estimation of cetacean abundance from line transect and markrecapture surveys are proposed. Using either generalized linear or generalized additive models (GLMs or GAMs), two approaches are suggested which allow heterogeneity in the spatial distribution of cetaceans to be modelled from standard line transect data. In the rst approach, the transect lines are divided into sm...

متن کاملQuasi-cylindrical 2.5D wave modeling for large-scale seismic surveys
[1] The most common form of seismic exploration remains a nearly linear survey with data acquisition lines including the source and receivers. The interpretation of amplitude and waveform information for such linear acquisition requires consideration of 3D seismic wavefields. In many scenarios the structure is approximately 2D, but still modeling is needed for point sources. In recent years 2.5...
