The following are some of the RoxAnn studies by various users world-wide.
An investigation of the relationship between
seabed type and benthic and bentho-pelagic biota using
acoustic techniques
Siwabessy, Paulus Justiananda Wisatadjaja
Curtin University of Technology, Department of Applied
Physics
A growing recognition of the need for effective marine
environmental management as a result of the increasing
exploitation of marine biological resources has highlighted
the need for high speed ecological seabed mapping. More...

Marine and Coastal Management - Dealing With
the Past - Mapping and cleaning up 40 years of cast-offs
at McMurdo Station
By C. K. Bretz, P.J. Iampietro, R.G. Kuitek
The United States established its first year-round research
base in Antarctica in 1956 to provide logistical and
operational support for polar science activities as
part of the International Geophysical Year (IGY, 1957-58).
Over the years, the Naval Air Facility McMurdo (renamed
McMurdo Station in 1961) has grown from a few dozen
prefabricated buildings that supported up to 100 men
to the present infrastructure which supports a human
population ranging from 200 over-winterers to a capacity
of 1200 during summer seasons. More...

Purbeck Marine Wildlife Reserve, Dorset
It may seem surprising that until a few years ago we
had only a vague idea of what was on the seabed of the
Purbeck Marine Wildlife Reserve. What little information
we had came from SEASEARCH divers but this only tells
us about small patches of seabed (visibility is generally
less than 10m underwater, even on a good day). The difficulty
comes in trying to work out what is in between. More...

Loch Maddy is a candidate Special Area of Conservation
under the EC Habitats and Species Directive for its
unusual topography and diverse ecology. Scottish Natural
Heritage, one of the UK government's conservation agencies,
commissioned a geophysical and biological survey of
Loch Maddy as part of the UK Marine SACs project. More...

Predicting the distribution of sublittoral
benthic biotopes using acoustic remote sensing
Journal of Coastal Conservation Volume: 8 Issue: 1 Pages:
25-33 Authors: Johnston, C., Davison, A.
To implement the European Directive on conservation
of natural habitats (92/43/EEC), government conservation
agencies, in this case Scottish Natural Heritage (SNH),
must identify areas as possible Special Areas of Conservation
(pSACs). More...

The use of seabed acoustic classification (RoxAnn)
in identifying the distribution of coral structures
Christophe Chevillon, Institut de Recherche pour le
Developpement, IRD (French Research Institute for Development)
- Formally known as Orstom, New Caledonia. As part of
a soft bottom study we used an hydro-acoustic seabed
classification system (RoxAnn‚) in the lagoons of New
Caledonia and Fiji. During our prospecting surveys,
focusing on the nature and distribution of the sediments,
we identified pinacles acoustic signature from that
of the sediments (muds, sands and gravels).More...
