Bathymetry and sidescan sonar imagery together reveal a slow-spreading ridge segment that has a large composite volcanic plateau at its center.
In the mid-1950s and on into the early seventies, researchers used sonar equipment with mixed results.
Despite using sonar equipment and modern technology, to date, scientists have found no conclusive proof of the monster's existence.
These poles are placed in concrete anchors, otherwise known as sonar tubes, to keep the building's structure secure.
They point to the odd sonar readings taken during numerous expeditions and the credibility of eyewitness accounts.
However, many sonar contacts were recorded, and the researchers generally found the evidence to be positive that something large inhabited Loch Ness whether or not it was a descendent of a long-necked aquatic relative of a dinosaur.
Although many experts dispute witness sightings, the modern video recordings and sonar recordings, Nessie remains a popular urban legend and the most documented example of cryptozoology.
Modern equipment, such as radar and sonar, have also increased the likelihood that if a large, 25-foot long creature lurked in the dark waters of Loch Ness, someone would find it.
While there is a great deal of anecdotal evidence, photographs, sonar readings and even video footage, many experts dispute these as hoaxes perpetuated by people who either want to make money or who want to continue the myth and legend.
On the other hand, sonar scans of Loch Ness have been inconclusive with no indisputable evidence pointing to a creature residing within even the deepest depths.
