EnvironmentA side scan sonar is used when high resolution information on specific seabed features is required (e.g. habitat mapping or wreck investigations). The unit is towed behind the vessel in close proximity to the seabed and transmits high frequency sound pulses that map the seabed...

EnvironmentThe term bathymetry refers to the ocean's depth relative to sea level, it can also be used to describe submarine topography or underwater terrain. INFOMAR bathymetry data is measured primarily by multibeam (MBES) and also singlebeam(SBES) echosounder devices. MBES transducers...

EnvironmentINFOMAR backscatter data is measured primarily by multibeam (MBES) and also singlebeam(SBES) echosounder devices. MBES transducers transmit multiple a high frequency pulses of sound from beneath a vessel in a fan shape down to the seabed. The amount of energy reflected back...

This is a 5 m resolution bathymetry tif in WGS84 projection. The survey was carried out on the R.V. Keary using a hull mounted EM3002 multibeam echosounder. Data was subsequently processed using CARIS HIPS and SIPS software. Depths in the survey area ranged from 0m to 55m, all...

Water tracing involves tagging water to see where it goes. The time the tracers take to get from one point to the other is also usually recorded. It is most commonly used in karst environments to ascertain groundwater flow rates, directions and catchment definitions (Zone of...
