Case Study: The Hayes Echo Sounder

Introduction

The well known assumption is that a safety of a ship is executed by having a proper disposal of navigational chart and a device or method fixing position on this chart in a vessel. The first great era of sea investigation finished in mid 1920s, offering rise to new techniques born of the fledging Electronic Age. Dr. Harvey Hayes of the U.S. Navy designed an echo sounder called the Hayes echo sounder, which in 1922, it is equipped in the USS steward. The advancement of echo sounding proceeded in the resulting years. By 1925 Submarine Signal Corporation was creating developed echo sounding devices called fathometers. (“Age of Electronics(1923-1945)” 2013). The efficiency of Echo sounder should affect your voyage by detecting other

This part focuses on the different topics that are needed on the study as solution. The different topics begin with an introduction basically needed to make the study successful, followed by the history or methodology used by people, and ended by different studies related. Related topics for the study: The first topic is Marine Radars. It is usually short range radars that are used by ships to pinpoint locations about the other ships and land in the area. The x-band or s-band are the frequencies with which these radars are operated. The x stands for secret, as the ship radar was mainly hidden frequency while used for the purpose of tracking ship during the Second World War. The second type is s-band which stands for small range. (Sharda, 2011). Radar was the result of research during the mid- and late-1930s by scientists and engineers in eight countries: Great Britain, Germany, Holland, France, Italy, USSR, Japan, and United States. Each nation believed that this was its own particular advancement and held the technology in highest secrecy. Great Britain gave the essentials to four advanced Commonwealth nations: Canada, South Africa, Australia, and New Zealand, and indigenous systems emerged in each before WWII. Hungary independently developed its own particular framework during the war. (Jr, Watson,

First one is measuring the depth. It is important for several different reasons, most significant is so that the vessel does not run ashore. There are accurate charts for all of the world’s major ports but our research ships sometimes visit poorly charted regions such as Antartica and so they need to be able to measure the depth is so that they don’t hit the sea floor. Second is looking for objects such as fish, icebergs or bubbles from deep sea vents in the water column. Echo sounder works by transmitting a pulse of sound directly downwards from the bottom of the ship. The pulse of sound travels down through the water, bounces off the sea bed and then travels upwards until the reflection is heard by the
