Hydrographic Survey: The science of measurement and description of features which affect maritime navigation, marine construction, dredging, offshore oil exploration/offshore oil drilling and related activities. Strong emphasis is placed on soundings, shorelines, tides, currents, seabed and submerged obstructions that relate to the previously mentioned activities.
Hydrographic survey covers a broad spectrum of disciplines and only a few are covered here. Be it mapping the seafloor, below the seafloor, what is on the seafloor, or the tides and currents above it, the solutions and interests are numerous. Some equipment that can be considered:
Fixing your equipment is important to ensure it is still there when you return. Being able to recover it too is as important and the EdgeTech range of acoustic releases and pop up buoys allow this.
In column ADCP buoys and floats, complimented by the range of bottom frames means that you can get your instrumentation in the exact place that you need it. Combined with inbuilt release systems (such as EdgeTech’s) means that the entire mooring can be recovered, serviced and redeployed.
Knowing where your assets are when underwater, or at night, requires high intensity and reliable lights such as the Novatech flashers. When the assets are recovered by a 3rd party, be it by a weather event, a trawler or through sabotage, being alerted and being able to track it via satellite gives an increased chance of recovery.
Keeping your sensors clean in a marine environment is always the challenge. Zebra-Tech’s range of wipers allows sensors for Tu, PAR, DO, etc. be physically wiped ensuring that the data you collect is as good as possible. A range of wipers for camera systems is also available ensuring your view is not obscurred and service visits by divers can be extended.
