Sonar

or removing water to go up.While the subs are above water they can just use GPS to navigate around but while the subs are underwater they navigate using sonar but they are virtually blind because the sonar requires sound to bounce off of something which is only useful if there is a ship or other subs around. There are two different types of sonar there is aggressive and passive, aggressive is when they send out a wave and passive is when they wait for one to be sent out and basically catch…

government didn’t just randomly pick dolphins and sea lions; they chose them because of their abilities. Dolphins have a biological sonar, a sense that allows them to use sounds to detect things around them. This can be used to detect the mines underwater. The manager of the marine mammals program, Mike Rothe, states “They’ve evolved over thousands of years to have a remarkable sonar. We’ve been developing UUVs for several decades.” Meanwhile, the sea lions are trained to use their enhanced…

The sun drifted high above the USS Maddox as the destroyer surged into enemy waters of the Gulf of Tonkin. Despite the waters being under international authority, the threat level of enemy attack was fairly high. The mission was to relay any intelligence gathered about North Vietnam to South Vietnam.

Rupert Gould published a book called “The Loch Ness Monster and Others”. When the very first photograph of Nessie was taken researchers began to use modern equipment to search the Loch for the monster. During the 1970’s a team of scientist used a sonar to track multiple objects in the loch that were about 20 to 30 feet long (Thomas 1). A.D. 565 is how far back the loch ness…

The priority is to make the ship sturdy and watertight. Submarines are ships that can stay underwater and also float on the surface. As you walk on the top of the submarine, you start seeing how this massive machine is built to remain…

Newly invented AUV’s, autonomous underwater vehicles, and ROV’s, remotely operated vehicles, finally allowed for a bigger look at the wreck. Each of these vehicles contained sonars, digital cameras, and sensors. Archaeologists finally had the technology to look at a whole underwater site comprehensively. With the new resources and a multiagency collaboration, a new expedition set out to create a site map of the Titanic in 2010…

Alfred Wegener is the man that introduced us to the Continental Drift Theory. He spent many years looking for clues from the past to support his idea of drifting continents.

knowledge we can only put forth an experience that we presume a bat is having. We as humans can analyze how a bat perceives its’ world from a scientific standpoint. We know bats use sonar location to perceive the world around them. Sonar location is an example of a phenomenon that we understand based solely upon research. Sonar location, along with other phenomenons are easy for humans to replicate in a scientific…
