Aquatic Habitat Mapping Software

Bathymetry and plant height map created with Visual Habitat 2.0 data. BioSonics has released Visual Habitat 2.0 (VH2), spe- cialized software for the assessment and mapping of aquatic habitat features including seagrass, bathymetry and various substrate types.

This upgraded version includes tools to generate full-color, interpolated maps with bathymetric contours. VH2 allows us- ers to interpolate and form gridded data using three different methods: Triangulated Linear Interpolation, Inverse Distance

Weighting and Ordinary Kriging. Users can print maps directly or export results as KML, shape? le or image ? les for use in

Google Earth or ArcGIS. VH2 also automatically computes grid statistics including the area, water volume and plant and volume. Existing users can download VH2 at no cost and a demo version is available for new users.

Buoyant Hybrid Cables

With the rise of smaller inspection class ROVs, the need for neutrally buoyant hybrid tethers has become clear, says Lin- den Photonics Inc. Linden Photonics has introduced a new buoyant hybrid cable with extreme ? exibility. By carefully controlling the speci? c gravity of the cable, a density can be achieved to allow the cable to ? oat just behind the ROV.

The precise control of buoyancy is critical so that the ROV is neither pulled up nor dragged down. Smaller ROVs are highly maneuverable and their versatility is hampered by a tether with large diameter or low ? exibility. www.lindenphotonics.com
