Map Of The Ocean Floor Features

The maps were created through computer analysis and modeling of new satellite data from esa s cryosat 2 and from the nasa cnes jason 1 as well as older data from missions flown in the 1980s and 90s.

Map of the ocean floor features.

Typically finely wrought ocean maps have been the result of extensive sonar. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Map showing the geographic extent of the arctic ocean as a darker blue tint. This is expensive and time consuming so sonar maps are mostly only made of places where ships spend the most time.

The northwest passage and northern sea route are two important seasonal waterways that connect the atlantic and pacific oceans. Detailed depth contours provide the size shape and distribution of underwater features. Among the new features they re now able to detect sandwell says are thousands of previously unknown seamounts between 1000 and 2000 meters tall dotting the ocean floor. Topographic maps of the sea floor.

Northwest passage northern sea route. In recent years the polar ice pack has thinned allowing for increased navigation through these routes and raising the possibility of future. This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet.

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 under water topography maps have been developed by the study of ocean floor topography.
