How to find satellites from space ships
#Cosmoread: It is estimated that some three million ships in the North Atlantic, possibly a quarter, with the rest scattered across the oceans. Now, according to new research satellites, locating these lost ships could be used to help.
In a study published in the Journal of Archaeological Science, marine geologist and colleagues of the Royal Belgian Institute of Natural Sciences Matthias Baeye explain that production vessels suspended particulate matter (SPM) concentration signals which are detected by high-resolution ocean color satellite data such NASA’s Landsat 8 as can be.
Typical of these particles downstream linear plumes shallow shipwreck sites as far as 2.5 miles of space to expand and therefore are easily identifiable.
“-8 Landsat data free of charge and therefore the acoustic method presented in the study and is an inexpensive alternative to laser surveying techniques, ‘Baeye and colleagues wrote.
Ships Storm history highlights
Researchers at the Belgian coast near the port of Zeebrugge four began their study by analyzing known wreck sites.
In water at least 49 feet from each other on a sandy bottom is located within 3 miles, the ships were all civilian ships.
Two ships, the SS and SS Samvurn Sansip being mined during World War II after the drowned. Swedish steamer Nippon, collided with another vessel in 1938, the SS neutrons, a Dutch steel cargo ship, a wreck, the SS in 1965, went down after hitting Sansip considered.
-8 Tide models and 21 cloud-free Landsat images use a set; the researchers mapped the wreck locations extending from sediment plumes.
22 ships found in the Greek campaign
They found that the SS and SS Samvurn Sansip sites, which were an important part of their structure from unburied SPM plumes, tide and downstream during flood tides could be detected.
An SPM plumes SS and SS Nippon neutrons, which are buried deep in the seabed were recorded in collaboration with.
“SPM plumes that a ship in the sea floor is exposed and buried indicators are certainly not,” Baeye and colleagues wrote.
According to the researchers, it makes the ship wrecks around the pits, scrape the exposed structure. Submerge the fine suspended material is deposited over slacks as the act (relatively still ebb and flood tide currents between periods).
Finds the largest shipwreck in history
Scour the pits again suspended when the current increases as source material for the work. Sediments reach the surface, they create linear plumes.
This in-depth study of all the rest, four vessels in relatively shallow water, since the new method has a limit of detection of wreck that have nothing to do. Satellites image plumes in the deep sea vessels can not.
However, given the millions of ships scattered throughout the oceans is important to find them is another tool.
“The ability to detect the presence of ships from space submerged archaeological scientists and resource managers interested in locating ships is of benefit,” the researchers concluded.
