plot of area of Earth's surface above any given elevation or depth above or below sea level
submerged outer edge of the continent
deep seafloor beyond the continental margin
Atlantic-type margins & face the edges of diverging tectonic plates. Very little earthquake/ volcanic activity here.
known as Pacific- type margins, are located near the edges of converging plates. Site of volcanic/ earthquake activity.
shallow, submerged edge of the continent
transition between continental shelf and the deep-ocean floor, has the steepest slope
abrupt transition from continental shelf to continental slope
accumulated sediment found at base of continental slope
cut into continental shelf and slope, often terminating on the deep-sea floor in a fan-shaped wedge of sediment
current propelled by gravity; underwater avalanche of sediments
fractures where lithospheric plates slide horizontally past one another. Active part of fracture zones
flat-topped sea mounts eroded by wave action
region of water flow influenced by proximity to surface
biogeneous sediment containing more than 30% of shells of planktonic organisms
composed of single-sized particles, energy fluctuates within a narrow range, deep-sea floor
poorly sorted sediments
mixture of sizes, energy fluctuates over a wide range, near submarine canyon by turbidity current
Autonomous Benthic Explorer
underwater robot, first AUV used by US
measures sea surface topography
Acoustic Doppler Current Profiler
used to measure how fast water is moving across water column
Conductivity, Temperature, and Depth Sensors
determine physical properties of water
