AUV Benthic Habitat Mapping in South Eastern Tasmania

Abstract: This paper describes a two week deployment of the Autonomous Underwater Vehicle (AUV) Sirius on the Tasman Peninsula in SE Tasmania and in the Huon Marine Protected Area (MPA) to the South West of Hobart. The objective of the deployments described in this work were to document biological assemblages associated with rocky reef systems in shelf waters beyond normal diving depths. At each location, multiple reefs were surveyed at a range of depths from approximately 50 m to 100 m depth. We illustrate how the AUV … Show more

“…Table I shows the distribution of labels for each dive within this dataset, along with the entropy of this label distribution. 1 In all, 20 dives were performed, but only 11 are used in this study. The remaining dives were either of insufficient length or did not contain a sufficient variety of habitat classes.…”

“…For a reasonably sized mission area, the distribution of the ripple orientations should be unimodal since sand ripples are created mainly by currents and waves [36][37][38]. 2 The result of the ripple detection algorithm effectively performs binary classification, segmenting the mission area according to whether each seabed location is characterized by sand ripple shadows. Let the binary information map, J , at a location (x, y) be equal to unity if the location is not characterized by shadows cast by a sand ripple; otherwise, J (x, y) = 0.…”

“…[3], [4,5], [6],and [2]), which has seen less attention when compared to mapping in other environments. Regardless, there are a large number of significant real life applications that can benefit from such technology including oceanography [7], marine biology [8], and archaeology [6], as well as for robot navigation (e.g. [9,10]).…”
