Out of all the technology mentioned in the passage, by far the most advanced has to be the LIDAR. Light Detection and Ranging is used to find objects above the ground quickly and efficiantly. It is the most useful technology used to make new discoveries.
In Florida Waters Treasure Hunters, Mel Fisher created his own technique of finding underwater treasures. He calls it the mailbox system. "A mailbox is a large metal tube that is bent 90 degrees, like an elbow. The tube has a diameter several inches larger than the width of the boats propellers. One end of the tube is fixed near the propeller and the other is placed in the water, aimed at the ocean bottom. When the boat engine is swiched on, powerful jets of water blow sand from the floor,

This is extremely dangerous. Technology is so far advanced, it is unneccisary for a human being to risk his or her life for data that can be found a simpler and safer way. In paragraph 4, Ralph O'Hair describes the intence winds that beat and endanger the plane "like a stick in a dog's mouth." It must be very unnerving, to be thrown around like that. The reason for brave pilots to do this now is explained in paragraph 10, "As it flies through the eyewall and the hurricane's center, the airplane launches dropsondes, small instruments attached to parachutes. The devices fall to the ocean and transmit bursts of data to the airplane twice every second. The data includes temperature, humidity, atmospheric pressure, as well as the speed and direction of winds." It is neccisary for scientist and meteorologist to come up with a safer way to collect …show more content…
One of these is infrared satellite imagery. This is explained in paragraph 2-"Infrared satellite imagery can locate objects on the ground less than two feet wide. Infrared light also can penetrate about a foot below the surface and detect differences in the soil." At first, this might seem like a great idea. But it has plenty of cons. In paragraph 4, it is explained that infrared satellite imagery needs manual help in order to reveal any discoveries, and that takes lots of time. It goes on in paragraph 6, stating that infrared cannot be used in jungles, which is exactly where many ancient civilizations hide, buried beneath the tree canopies. It also doesn't scan very deep, so anything over a foot below the surface will remain undescoverd. Another technique is brought up in paragraph 11, called Ground Penetrating Radar (GPR). "The GPR sent pulses of microwave energy underground, where it bounced off buried objects. They used state of the art software to analyze the radar echoes and constructed a 3D map," (Paragraph 11). Once again, this technology has serious negatives. Scientists had to drag this bulky lawnmover-like machine in blazing heat across the jungle floor (paragraph 11). This machine is great for a workout, but not it you want to discover lost civilizations
Although the tornado of 10 June 1938 has been known about, at least anecdotally, within the scientific community since it was brought to light in 1939 by Metro-Goldwyn-Mayer, this potentially rich source of historic information has lain fallow. It is within this rich field of mobile, American thinking that we undertake this effort. A team of scientists with courage, brains, and even heart brought the resources to bear on the challenge.
Archaeology is a continuously evolving field where there is a constant stream of new branches 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. Underwater archaeology’s role has increased in recent years as it allows archaeologists to more accurately interpret the past by supplementing information gained through traditional land excavations.

Hurricane preparation is the most important thing in staying safe during a hurricane. Through technology we are able to track these hurricanes and have time to get ready for them. Recovery takes a lot of time and work, but safety and injury prevention should be your number one concern.
Leading up to the hurricane, many scientists expected the storm to dissipate over the ocean and cause little to no harm (Rappaport). The scientists were relying on faulty equipment that said that due to slow air speed and l...
to reduce the number of fatalities in serious storms is to give people more warning time for them to go to a safer place. Many times in hurricanes people are told to evacuate there city or state. The more time that people have to do this the more that people will do this. Throughout the entire hurricane season meteorologists keep a close watch on the Atlantic and the Pacific Oceans. They examine pictures of the area taken by satellites, and also take information on air pressure, wind speed, and temperatures.
Once upon a time, the lone metal detectorist combing the beach was an oddity. These days, they're borderline hip. It used to be that beach essentials meant suntan oil or sunscreen, large and colorful towels, floppy hats, a Frisbee or a volleyball. Now, some can add a treasure metal detector to the list and no one will find it strange or out of place.
The Hurricane Center is trying new ideas on how to better forecast hurricanes, “The Hurricane Center introduced experimental warnings for storm surge, the rise in sea level that can accompany hurricanes and arrives ahead of them” (Main). The experimental warning maps show the meteorologists where the storm surge flooding could likely occur, and how high the water could reach above the ground. The improvement of forecasting is due to, “much of the improvement comes from faster computers and better models, which allows for more accurate predictions of a storm’s behavior” (Main). The progression of faster and more advanced technology has made forecasting more accurate. The development of better computers is leading to more accurate predictions, “As the computers get faster, the computer model’s resolution increases, the ability to see higher and finer detail in the atmosphere increase. So as the models get better, our forecast errors go down” (Casey). Computers are helping lead to lower error percentage for forecasting hurricanes. Although computers are getting better, satellites are also helping the error percentage go down. The computer uses information given by meteorologists, and the meteorologists get their calculations or measurements from satellites, “You have to get the model off to a good start so part of the key to improving predictions is better measurements of the atmosphere
In the hurricane the mixture of the water and winds can be extremely damaging. The winds are extremely dangerous and usually don’t go faster than about 75 miles per hour but have been documented to go as fast as 85 miles per hour. Due to the fact that hurricanes need water to survive they cannot go too far on land, but that does not stop them from causing billions of dollars in damages. Hurricanes are so dangerous that they were listed number 1 on the Department of Earth and Atmospheric Sciences, Hazard and Disasters list.
The hands-on experience and hardship of discovering ruins and ancient tombs are a thing of the past. There are many technological advances used today to discover the unknown, and provide estimates of them. Treasure hunters use water dredges or "the mailbox system." Archeologists use LIDAR (Light Detection and Ranging) or GPR (Ground Penetrating Radar), and most importantly, Hurricane hunters use planes, dropsondes, and satellites to gather information about hurricanes. Dropsondes and satellites are the most important and most technologically advanced system used by modern adventurers, because their information is used to warn citizens of the dangers of individual hurricanes, maybe causing them to evacuate.
"Crash" trees are toppling over and houses are being ripped to shreds. What is happening you may ask? Well, we have enter the mouth of a beast. This is not an average thunder storm that you get every now and then, we are in a hurricane and a tornado. Hurricanes an tornado can both cause extreme damage, can come in a variety of sizes, and can happen at any moment. So now, let's begin the journey of a life time to learn about hurricanes and tornado.
The first step used in excavation is surveying the remote area; it is the controlled exploration of what is to be found underneath the ground. Excavation is usually uses techniques such as making grids of the trenches and shovel testing. Shovel testing it is a standardized test that archeologists use to test their research in a real world setting. Shovel test pits or STPs are small holes dug on a grid that allow archeologists to pick up artifact samples and stratigraph data across large areas of land. Stratigraphy is results based on what geologists and archeologists get using a process where layers of soil and debris are laid down on top of one another over time. An STP survey is a great method for understanding and recognizing important shifts in the patterns of human activity. STP was used in instructive ways enslaved people were working and living throughout the eighteenth and nineteenth centuries. Shovel test pits are a method used by archeologists that can cover an area quickly and are less invasive (shovel test pit methods pg.1). Culture-historical archeology will be a step used in analyzing artifacts and materials found in excavation and from doing shovel testing. Archaeological excavation aims to identify any evidence of past human activity that may be buried below ground at any given site. This evidence usually consists of features, such as buried soil layers, rubbish pits, ditches, graves or parts of former buildings such as postholes, wall foundations and floor surfaces and the finds material that has ended up within the features. Although some finds will have been deliberately buried, such as grave goods or treasure hoards, most of the finds material found by archaeologists is the discarded rubbish from the activities of everyday life and work in a settlement. Due to the small size of a Test Pit you might need a bit of luck to find a proper archaeological feature such as a pit or building
He knew that once “the ground was disturbed, it could never be returned to its original state” (112). In consideration of this fact, he would spend a great deal of time surveying the land. With today’s technology, archaeologists can use ground penetrating radar and LIDAR to find archaeological sites without digging into unknown land. Ground penetrating radar sends an electromagnetic signal into the ground and uses the reflections to determine how far they need to dig. It even has the ability to recognize small objects that are profoundly deep and can be used to plot data and map out the land. Lidar stands for “light radar” and is similar to ground penetrating radar except it uses a laser to detect how much depth there is. Additionally, lidar can pass through tree tops, which is advantageous to archaeologists for mapping the land. A modern advancement in the archaeological technology used today, which would have been helpful to Metz, is magnetometry and the use of magnetometers. Magnetometers can detect brick, iron, or even burned soil within the earth by using a sensor that reads the strength of a magnetic field. Along with advanced archaeological technology, scientific methods have also changed and improved since the 19th
A hurricane is a type of natural disaster that can be harmful and destructive to anything in its way. Every year five to six hurricanes are formed, damaging and destroying people’s homes, landmarks, and anything in its path (“Hurricane”). Before a hurricane is developed it is known as a tropical storm. To be a tropical storm wind speed must be at least thirty eight miles per hour (“Hurricane”). Once wind speeds reaches seventy four miles an hour it can then be classified as hurricane (“Hurricane”). Large scale storms, like hurricanes have a variety of ways to measure the sev...
