is one of the first complete representations of the ocean floor. But as detailed as this map appears, it is hardly an accurate depiction of seabed topography. Instead, it is the product of educated guesswork: At the time of the map's creation, reliable seafloor data was scarce. ...
Topography and Seismic Effects The many islands in the Caribbean create lots of areas of shallow water, which can be treacherous to ships [source: NOAA]. But at the same time, some of the deepest trenches in the world are found in the area of the Bermuda Triangle, including the Puerto Ri...
The island was discovered by Columbus in 1493, during his second voyage to the New World. Mona Island has been a nature reserve since 1919 and uninhabited for more than 50 years. Due to the islands’ unique topography and ecology, Mona, Desecheo and Monito have been nicknamed “The Galápago...
“Doppler” part allows us to get an estimate of wind speed. Things get interesting when we see a velocity couplet, or two opposing wind speeds next to each other, as this can sometimes be a signal of a developing tornadic storm. But, the radar also shows all kinds of non-meteorological...
there are certain characteristics of welded fall deposits that separate them from phonolitic lavas: welded fall deposits grade laterally and vertically into non-welded deposits, have mantle topography, contain lithic clasts and do not have autobreccias at their margins unless they have become rheomor...
It’s not the Hawaii you picture when you close your eyes—it’s nowhere near the beach, and there’s more red rock than rainforest— but that’s exactly why I love it. All the other islands have those beautiful beach hikes or volcanic terrain; this 5.3-mile adventure is one of a ...
Our users around the world practice The Science of Where, by mapping the ocean floor; by making organizations smarter; by implementing retail loca- tion strategies; by building strong, resilient economies. They understand and embrace the knowledge and commitment to make these kinds of projects ...
all of which originated as separate submarine volcanoes emerging from the floor of the Atlantic Ocean. The two most easterly islands—Fuerteventura and Lanzarote—appeared about 20.2 million years ago. However, the three middle islands—Gran Canaria, Tenerife, and La Gomera—date to much later in ...
“The way we’re doing that is to use a satellite altimeter (高度计), a radar to map the topography (地貌) of the ocean surface. Now that seems sort of strange that you’d map the topography of the ocean surface when you really want to get at the sea floor. But, the ocean surfac...
