Three countries developed a new technology – High-resolution 3-D maps of Antarctic sea ice (below sea level)

Scientists from the USA, UK and Australia developed an underwater robot; they said “this mission provides a perfect ice thickness measurement from areas that were previously not easy to access.”

With the help of satellite, they can measure the large-scale thickness of the ice above the sea level. But it’s difficult to measure ice thickness – below the surface of the sea. With the help of this mission AUV (Autonomous Underwater Vehicle) known as SeaBED is easy to measure.

SeaBEDBefore the mission, they measurements made on the sea ice by slicing outlets, together with visual notes from ships are not easier for building a more complete picture; sometimes the data are not clear in getting access to thicker areas of sea ice leaves gaps. SeaBED has an invaluable new tool to fill this gap. This mission is operated at a depth of 20-30 meters and was driven in a lawn mower pattern, which is weighs nearly 200 kilograms and has a twin-hull design that gives the robot to have better stability for low-speed photographic surveys.

Hanumant Singh is an engineering scientist at the WHOI (Woods Hole Oceanographic Institution) who operated the AUV, says “Putting an AUV together to map the underside of sea ice is challenging from a software, navigation and audio communications point of view.”

Co-author for BAS (British Antarctic Survey), Dr Jeremy Wilkinson says that “’The AUV missions have given us a genuine insight into the nature of Antarctic sea ice – similar to looking through a microscope. Now we can calculate the ice easily in a distant with better facts and were animated to measure ice up to 17 meters solid.”

Auto starts Control Module – Deep Sea Electronics 5110

OS: Windows 95, 98, 2000, Me, NT, XP, Vista, Windows 7
Version: 1.26a

The DSE5110 is an Automatic Start, Control Module planned to automatically start and stop diesel and gas generating sets that include non electronic engines. The module also provides outstanding engine monitoring and security characteristics.

DSE 5110

The module has the facility to monitor over speed, under speed, charge failure, emergency stop, low oil pressure, high engine temperature, fail to start, fail to stop and loss of the speed sensing signal. The module displays fault conditions on the LCD display and via the LED pointers on the front.

The modules are controlled using the front STOP, AUTO and MANUAL push buttons and also includes TEST button. An additional PUSH button lying on both modules permits the user to scroll through the LCD instrumentation display. LCD displays with the following Instrumentation displays, accessed via The SCROLL push-button:

  • Generator Volts L1-N, L2-N, L3-N
  • Generator Volts L1-L2, L2-L3, L3-L1
  • Generator Frequency Hz
  • Generator Amps L1, L2, L3
  • Engine Temperature (Degrees in Celsius and Fahrenheit)
  • Engine Speed RPM
  • Engine Oil Pressure (PSI & Bar)
  • Plant Battery Volts
  • Engine Hours Run
