Ocean Floor Topography Flow Chart

In this 3 4 day investigation students will develop an understanding of the two basic ways seafloor topography influences ocean circulation patterns steering ocean flows and providing barriers to deep water mixing.

Ocean floor topography flow chart.

Organize information about ocean floor topography by completing the following flow chart. Arctic ocean arctic ocean topography of the ocean floor. Ocean topography off the southeast portion of the united states. This community lives in or near marine sedimentary environments from tidal pools along the foreshore out to the continental shelf and then down to the abyssal depths the benthic zone is the ecological region on in and immediately above the seabed including the sediment surface.

Predict where the oldest rocks in the atlantic ocean are. 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. The under water topography maps have been developed by the study of ocean floor topography. Scientists used multibeam bathymetric data to create a 3 d view of a portion of the charleston bump.

Predict where the youngest rocks are. Researchers today published the most detailed map of the ocean floor ever produced. This study is extensive and it has been established that the ocean floor has similar features of mountains and valleys as on the earth. They will draw and then construct a seafloor model and experiment with solutions of colored saline water to see how they behave when encountering underwater barriers.

3 section 17 2 seafloor spreading 1. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. Multibeam sonar map of the seamounts. Explorations after 1950 revealed the true complex nature of the ocean floor.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Ocean floor topography involves the study of ocean bottom features including the outer continental shelf continental slopes and ocean waves desktops. Sea surface temperature readings. From the late 19th century when the norwegian explorer fridtjof nansen first discovered an ocean in the central arctic until the middle of the 20th century it was believed that the arctic ocean was a single large basin.

Data collected by satellites and remote sensing instruments were used to created a model at least twice as. 18 1 the topography of the sea floor we examined the topography of the sea floor from the perspective of plate tectonics in chapter 10 but here we are going to take another look at bathymetry from an oceanographic perspective. Use maps in your text as a resource. Topographic maps of the sea floor produced at a 1 100 000 scale that contain loran c rates bottom sediment types and known bottom obstructions.

Benthos is the community of organisms which live on in or near the seabed the area known as the benthic zone.
