Self-Contained Underwater Breathing Apparatus
What is SCUBA gear?
A vast, flat expanse of the deep ocean floor, typically found at depths between 3,000 and 6,000 meters.
What is an abyssal plain?
A linear lowland area created by the splitting of the Earth's crust.
What is a rift valley?
conical, underwater volcanos that haven't reached the surface yet
What is a seamount?
Process where deep, cool, nutrient-rich ocean water rises to the surface, replacing the warmer, nutrient-depleted surface water
What is upwelling?
Underwater robots deployed from ship to sea to record and collect information from the ocean
A gently sloping surface located between the steeper continental slope and the deep ocean floor (abyssal plain).
What is the continental rise?
The amount of salt in a body of water or soil.
What is Salinity?
Long, narrow, deep depressions on the seafloor, formed when one tectonic plate slides beneath another.
What is a trench?
A process where surface water, influenced by wind and other factors, sinks to deeper layers of the ocean.
What is down-welling?
Acronym for SOund Navigation and Ranging, this technology utilizes sound waves to detect and locate objects underwater.
What is SONAR?
the steep, sloping part of the continental margin that extends from the edge of the continental shelf down to the deep ocean floor
What is the continental slope?
Long continuous mountain range on seafloor formed by plate tectonics, specifically at divergent plate boundaries where new oceanic crust is created
What is a Mid-Oceanic ridge?
openings in the seafloor that spew out geothermically heated water rich in dissolved minerals.
What are hydrogen sulfide geysers?
A warm and swift Atlantic current that originates in the Gulf of Mexico and flows through the Florida Straits and up the Eastern coastline of the U.S., ultimately veering NE towards Iceland and Europe.
What is the Gulf Stream?
The measurement of depth of water in oceans, seas, and lakes.
What is Bathymetry?
the gently sloping, submerged edge of a continent that extends from the coastline to the continental slope.
What is the continental shelf?
A thin transition layer in a body of water where temperature changes rapidly with depth.
What is a thermocline?
A curved chain of volcanic islands located at a tectonic plate margin.
What is an Island arc?
the periodic rise and fall of sea levels caused by the gravitational pull of the Moon and the Sun
What are tides?
Large bowl-shaped depression on the Earth's surface that holds the water of an ocean.
What is an Ocean Basin?
the transition zone between a continent and an oceanic basin, made up of the continental shelf, slope, and rise
What is the continental margin?
a measure of how compact the mass in a substance or object is.
What is Density?
Flat-topped seamounts that have been eroded by waves and currents and then submerged.
What is a guyout?
An apparent force that arises from the rotation of the Earth, causing moving objects to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
What is the Coriolis Effect?
