Hydrographic surveying is a scientific field and career path that many people may not know about. NOAA measures the depth of the seafloor using multibeam sonar from ships. Computers analyze the time it takes for sound waves to travel from the ship to the seafloor and back. This provides amazing detail of the seafloor.

Obtain a 3-dimensional seafloor model in a box covered with paper from your teacher. The paper represents the water surface. If your teacher has not already done so, tape the paper with a 1 cm grid on top of the paper cover.. You have been given the opportunity as a preeminent oceanographer to descend to the ocean floor in a submersible on.

Ocean Trench. Deep, deep below the water's surface lie vast, unexplored regions of the ocean floor: trenches. These underwater canyons are the deepest spots in the ocean. In fact, from sea level, the surface of the earth extends further down than it does up! Mt. Everest is the tallest point on earth (elevation wise) at 8,848 meters (29,029 feet).

Basically, students are instructed to create a model of ocean floor features (continental shelf, continental slope, abyssal plain, trench, mid-ocean ridge, seamount, and volcanic island). The model must be three-dimensional, but the modeling material is student choice. I do provide a salt dough recipe to give students an idea of where to start.

The new map portrays seafloor features as narrow as 5 kilometers (3 miles). An international scientific team recently published a new map of the ocean floor based on Earth's gravity field, and it is a particularly useful tool. The maps were created through computer analysis and modeling of new satellite data from ESA's CryoSat-2 and from.

PDF Tools Share Abstract We present an updated oceanic crustal age grid and a set of complementary grids including spreading rate, asymmetry, direction, and obliquity. Our data set is based on a selected set of magnetic anomaly identifications and the plate tectonic model of Mรผller et al. (2019, 10.1029/2018TC005462 ).
Ocean Floor Model
The sea surface is not flat; gravity causes it to be slightly higher over elevated features on the ocean floor, and slightly lower over trenches and other depressions. Satellites send out radio waves, and similar to an echosounder, can use the returning waves to detect differences in sea surface height down to 3-6 cm (Figure \(\PageIndex{5}\)).

Seafloor Mapping. Our global ocean covers over 70% of the Earth's surface. The marine ecosystem is the largest and most abundant in the world. However, most of the ocean is permanently dark, cold, and incredibly difficult to observe. Only slightly more than 23% of the seafloor has been mapped in great detail, and even less has been explored.

Atoll. A ring-shaped coral reef surrounding a lagoon. It may have low sand islands. Atolls rest on submerged volcanic islands. Bank. A navigable shallow area of the ocean caused either by elevation of the seafloor or by submergence of a landmass. Bay. An inlet of the sea; an indentation in the shoreline, often between headlands or capes. Cape.
