deepest depths of the ocean using special equipment produced by the military and commercial companies such as sonar to measure the ocean bottom. What is sonar? Sonar which is short for Sound Navigation and Ranging, uses sound waves to calculate distances from objects in water. This information can be used to produce maps of lake bed or sea floor. Sound waves are produced from an active sonar transducer. The sound wave travels outwards from the transducer and bounces off objects on the sea floor.
volume 27 number 3: 319-328. The article by the various authors listed above concentrated on the various techniques that are used to locate and then to excavate these sites. They list and discuss the various techniques that they use. These vary from side-scanning to locate the sites to high resolution video to see how the site appears and the various locations of the artifacts. The Titanic and the Bismarck were just two of the examples that were given for recent excavations. The article also discussed
Science, Marine Technology program. I have worked with the ROVs that Northwestern Michigan College has acquired and it has only fueled my admiration of the technology that goes into them. Along with ROVs, I have also worked with; multibeam, side scan, and profiling sonar systems, and I am amazed at the capabilities they have. When these systems are implemented they allow us a new and better understanding of the world below our lakes and oceans. I have worked several hours on NMC’s research vessel the
ocean. The navy using SLS side looking sonar was able to detect an aerodynamic fin longer than a football field and longer than any known wingspan. Also using the fusel lodge extra high resolution SLS bottom scan they figured out that the spacecraft was buried under 8 yards of quarrel. Knowing that the pacific quarrel grows at a rate of an inch a year they were able to calculate that the spacecraft crashed about 300 years ago. Also there is a low level hum that the sonar can pick up. ...
The archaeology of shipwrecks is an academic field that focuses on studying and exploring shipwrecks of the past. The shipwrecks discovered all around the world serves as a bridge to understanding the past and the lost cultural heritage, and teaching lessons on “how the environment and human error can damage each other.” One of the most famous and historic shipwrecks that helped shape the United States’ maritime warfare is the USS Monitor. Through the help of modern underwater technology, the shipwreck
Humanity was and always is attracted to the concept of an artificial being that would make life easier and more enjoyable. The word Robot was introduced in 1921 by Karel Capek, who was a check writer in his play "R.U.R" (Rossuum's Universal Robots ) that originally meant compulsory labor. Then in 1927 Fritz Lang, in his movie Metropolis was the first to project a robot in the modern meaning. Nowadays the general understanding about robots, according to the Robot Institute of America as of 1979,

Archaeology is the closest thing we have to a time machine. It is the only way we can know the unrecorded, and sometimes even the recorded, past. History may be written by the victorious, but archaeology is about the common people. There are archaeological sites ranging in age from thousands-of-years-old prehistoric habitations, to the Egyptian pyramids, to World War II military bases. As a means of obtaining knowledge about our collective past, archaeology has been unsurpassed. It is the literal
and excavation methods. Due to the influx of new technologies and innovations in recent decades, archaeologists have been able to excavate previously inaccessible areas. For example, new diving equipment and tools such as proton magnetometers, side-scan sonar, sub-bottom profiler, and miniature submarines have allowed archaeologists to dive into the deep depths of the ocean. As a result, the branch of underwater archaeology was created to search for shipwrecks and other artifacts on the ocean floor
It features a tiny telescope, which is placed inside an incision in the patient’s body. The telescope takes images from two points, which are relayed back to a console so the surgeon has a 3D image on-screen while he operates (Fig. 3). • The patient-side cart comprises three or four robotic arms, two or three instrument arms and one endoscope arm that perform the commands as dictated by the surgeon. • Wrist instruments enable the surgeon to perform tasks such as clamping and stitching as they are
Joe Reschke 8E #19 December 9, 2013 Research Paper There are about 3-4 million shipwrecks in the world. The shipwrecks are mostly spread in the Great Lakes and in the Oceans. Great Lakes Shipwreck Museum estimates that about 6,000 ships are wrecked on the bottom of the Great Lakes. The United Nations estimates about 3 million shipwrecks on the ocean floor. The great lakes, which can be seen from space, are the largest freshwater system in the world. The lakes are home to 3,500 species of plants
For over one hundred and fifty years inquiries and research projects, some more beneficial than others, have been made into the preserved remains of lake dwellings found across Europe. The unique discoveries of pile dwellings in Lake Zurich in 1854 ignited the frantic search for more prehistoric sites, attracting interest from antiquarians seeking to better our understanding of the past (Menotti, 2004). Hundreds of new sites were found and the works of early archaeologists like Munro and Keller provided
Everyone thinks they know the tragic story of the RMS Titanic (Titanic). Everyone thinks they know the statistics. But there is so much more than meets the eye. Few know whose fault it was that 1,518 people died or that only 706 lived. Few know the stories behind all of these people. Few know the story of the band and their last efforts to calm the passengers. Some know of Dr. Robert Ballard and his amazing discovery. And most have seen the movie. What follows is information about “that fateful night”
