Sentences with phrase «underwater gliders»
"Underwater gliders" refers to autonomous vehicles that can travel underwater, similar to how gliders fly in the air. They are designed to move smoothly through the water using wings or fins instead of engines, making them energy-efficient and capable of collecting data from various depths. Full definition
Called the Slocum underwater glider, the sub's mission was to bring back critical data on how much sea ice is melting due to the rise in ocean temperatures and, ultimately, to help researchers build a digital model to predict sea level rise.

Combining the classic but usually disparate physics of airplane wings and golf balls, the surprising reversal might serve to make a new type of mechanical switch that would flip off or on depending on how fast fluid flows past it or perhaps to stabilize machines like underwater gliders.
Perhaps most speculatively, Bot says, such switches might control and stabilize an aircraft or underwater glider in a completely mechanical way, without the need for electrical sensors and powered control systems.
AUVs such as underwater gliders are valuable research tools limited primarily by their energy budget — every bit of battery power wasted via inefficient trajectories cuts into the time they can spend working.
The Office of Naval Research is supporting Mahmoudian's effort with a $ 125,000 grant to build the four low - cost underwater gliders.
In addition to changes in the penguin populations, Palmer Station researchers track changes in sea ice and the marine food web, and pioneered the use of underwater gliders to explore below the Antarctic waters.
The dead zone's return was discovered by oceanographers at Oregon State University, who deployed robotic underwater gliders and other monitoring devices over the past few months to assess oxygen levels in the water.They discovered that oxygen levels on reefs previously devastated by past dead zones had dropped to 0.5 mL / L by the end of June — a far cry from the 1.4 mL / L level considered to be hypoxic for most marine life.
Called the Slocum underwater glider, the sub propels itself through water with a single - stroke piston, thereby conserving most of its energy for data collection.
The MIT researchers tested their system on an autonomous underwater glider, and demonstrated that the robot was able to operate safely among a number of other autonomous vehicles, while receiving higher - level commands.
Spray Function: As with Argo, an adjustable oil pack enables this underwater glider to sink and rise, while wings on each side propel it forward at 10 inches per second.
Underwater gliders and other types of AUVs already play an important role in addressing some of today's most pressing environmental, safety and biological challenges.
Mahmoudian's AUVs, named ROUGHIEs (for Research Oriented Underwater Gliders for Hands - on Investigative Engineering) will be underwater gliders.
CORA includes data from additional research vessels, buoys, underwater gliders, and other on - location sources.
