Rogue waves, also known as freak waves or monster waves, are large, spontaneous ocean surface waves that occur far out at sea and threaten large ships and ocean liners. Rogue waves can reach heights of over 30 meters and exert phenomenal pressure. While once considered a legend, recent testimonies and scientific research have confirmed their existence in all oceans of the world. Scientists do not fully agree on what causes these giant waves to emerge but are developing computer modeling techniques to better forecast where and when rogue waves may occur. Ships are being built stronger and satellites installed to monitor oceans for rogue wave activity.

2. Presentation
Rogue waves, also known as freak waves, monster waves, killer waves…are large and
spontaneous ocean surface waves that occur far out at sea, and are a threat to large ships
and ocean liners.
One of the few pictures of a rogue wave
Formerly considered as a legend, testimonies and scientific researches have recently confirmed
their existence. Rogue waves have been observed in all oceans of the world.
Rogue waves can reach heights of over 30 meters and phenomenal pressure. The rescued
sailors who have encountered them describe them as a wall of water that strikes the ship.
Scientists don’t always agree on the various theories about the emergence of these giant waves.
Means are put in place to fight against this phenomenon: Satellites have been installed to
supervise their appearances in oceans and ships are built stronger.

4. Why this subject?
I chose this subject because I think this
phenomenon is fascinating. An Internet watch
would collect all the information on this
phenomenon which seems to be increasing.
For whom?
This Internet watch is for fans, scientists and sailors.

What are rogue waves?
Author: Beth LEBWOHL Date of publication: October 13, 2012
Abstract:
Presents an article, in a blog about Earth Sciences, which defines the specifications of rogue
waves. Lev Kaplan, a professor of physics, explains how these waves appears and why it's difficult
to predict their advents.

6. TOOLS
● Netvibes:
I created 2 dashboards:
- « Rogue waves » and - « Freak waves ». I can be informed about news, videos, and
conversations around the themes i chosed. It's quick and easy.

● Google news

7. ● Google alerts
● I created 3 Google alerts : « Rogue waves », « Freak waves »and « Monster waves ».

8. ● RSS Feeds + Google reader
● I frequently receive newsletters from the site www.windfinder.com. We can find
observations and forecasts of wind, waves and weather on this site.
