The further we dive down from the surface, the less new food is available, making the fight to survive that much more challenging. At this depth, we’ve reached the average depth of the deep-sea floor, a place that may start to get a little muddy. By 13,000 feet (4,000 meters), the temperature hovers just below the temperature of your refridgerator. ![]() Any light still filtering down has diminished to appear completely black, leaving only animals and bacteria to produce the light found here. Dive deeper and the weight of the water above continues to accumulate to a massive crushing force. By 650 feet (200 m) all the light is gone to our eyes and the temperature has dropped dramatically. As you dive down through this vast living space you notice that light starts fading rapidly. But the deep sea remains largely unexplored. However, the introduction of the Synthetic-Aperture Radar (SAR) and its two-dimensional sea surface images helped detect potentially hazardous cross-sea scenarios, even in cloudy and adverse weather conditions.Below the ocean’s surface is a mysterious world that accounts for over 95 percent of Earth’s living space-it could hide 20 Washington Monuments stacked on top of each other. In one of its scientific expeditions, the German research icebreaker vessel RV Polarstern detected and recorded a heavy rolling event created by square waves. Most of them occurred around the time fast temporal variations of sea state parameters were observed and when wind sea and swell were almost perfectly aligned. So, when two wave systems create an oblique angle wave, it can interfere with shipping routes and cause accidents.Īccording to the European Space Agency (ESA), these square waves were responsible for a large percentage of ship accidents from 1995 to 1999. Wave diffraction is the bending of waves due to interaction with coastal features and obstructions like cliffs, headlands, or breakwaters. Wave refraction is the bending of swells and wave trains due to sudden and more or less changes in depth and bathymetry. On a small scale, it was also witnessed by SurferToday in Helsinki's Mustikkamaa island in Finland.Īs we've seen above, a cross-sea state is the result of several oceanographic phenomena taking place near the coastline, including: The picture above shows the checkered wave pattern between two breakwaters near Lisbon, Portugal, but the occurrence has also been spotted at New Zealand's Whangamatā Beach. Nevertheless, it has also been spotted in open waters in the South Pacific and the Atlantic Ocean. The island, located off the coast of La Rochelle, is a tourist attraction even though cross seas only occur during certain times of the year. The most famous place in the world for watching square waves is Île de Ré - Isle of Ré - in France, as seen in the top picture. They can reach 10 feet (three meters) in height.Ĭross seas are relatively rare and can appear and disappear within minutes on many beaches worldwide. Square-shaped waves are fascinating, but these criss-cross ripples pose a real threat to everyone and are too strong to get out of. Swimming or surfing in the middle of a cross-sea is not something you should be doing, even if you're an experienced swimmer or wave rider.Ĭross swells can also cause boating accidents and shipwrecks. Why? Because the phenomenon is usually associated with strong and localized rip tides. If you see square waves in the ocean, get out of the water as soon as possible. The look of square waves is impressive, but they're extremely dangerous, even in small swell conditions. When two opposing swells collide, a unique pattern emerges. In other words, square waves result from the intersection of two seas, also known as cross-sea or grid waves.Ī weather pattern in the region causes the waves to form at different angles. Instead, they're the result of the way the water is moving. However, square waves do not result from any circumstance that is taking place below the water. You can easily spot the strange pattern by climbing to the top of a lighthouse or cliff or flying a drone over the area. Looking at these waves from above, it seems like there's an underwater grid forming square-shaped ripples. The phenomenon is rare yet extremely dangerous. However, in some regions of the world, you may notice the creation of a chessboard-like pattern on the surface of the water. Most waves reach the shore and break horizontally and parallel to the coastline. Have you ever spotted a quadrilateral-shaped wave pattern in the ocean? If so, you've witnessed square waves.
