There are five of these boundary currents. %# , #&')*)-0-(0%()( C Towards the polls, freshwater from melting ice decreases the surface salinity once again. Operates: At the surface by hand Affected by: slows the movement of water and increases evaporation from reservoirs; may hold water back, store water, control flooding, and generate electricity. when the amount of sediment becomes greater than the carrying capacity of the force that is moving it; sediment from eroded materials settles. =non-biodegradable trash and plastic The key answer is that the shape of the gyre is determined by whether the winds torque the water in a clockwise or in a counterclockwise direction. B. S;xMx /S A fan created as an underwater current deposits sediment. Process in which sediment is laid down in new locations. Notes: Samples from the Ekman Grab and Soft Bottom Modified Petersen Grab are often processed with this in studies looking for organisms living in the sediments, the wash bucket gets rid of most of the sediments and all that is left are the critters (worms, snails, clams and small crustaceans) that live in the mud or sand. 136 0 obj +high gradient = rapid flow of water Chambers are then inserted into the sediment and sealed to isolate portions of the bottom from surrounding seawater. A large stream of moving water that flows through the oceans. +Commonly associated with limestone, streams that terminate abruptly by seeping into the ground, a deep, hollowed-out area under the earth's surface.

However, the connection between the atmosphere and ocean (atmospheric circulations and wind driving ocean surface currents) is one key thing (see explanation above). Recently developed dual-frequency sidescan sonar can even be used to distinguish rock types. Water gets pulled down through the ground until it reaches a layer it can't penetrate. This information is important for understanding how water tracers and pollutants are transported by the ocean. . ]zT8S %HFO$e@ endobj Operates: At any depth on a cable or line by free fall (no messenger needed) Notes: Racks on side for reversing thermometers that record temperature of water when rotated 180 degrees (thus, when bottle rotates, temperature at that depth is recorded), Samples: Water The distance and direction that a wave travels, The type of animal to most likely live on a sandy beach, A common toxic substance found on all muddy beaches.

Teams will then be asked to answer questions, perform calculations, and otherwise solve the tasks they are given. Floats can be weighted to be neutrally buoyant at a particular depth, where they drift in the current while emitting periodic sounds. A system in a steady state since forward reaction and backward reaction occur at the same rate; the rate of loss is equal to the rate of gain. Anchors are connected to holding lines with acoustic couplings that are released to recall the instruments. When one river 'robs' another of its water (see image), wetlands that form as rivers empty their water and sediment into another body of water. of a reaction by lowering the activation energy, but it c.

This zone is saturated with water. develops where streams flow away from a common high point on cone- or dome-shaped geologic structures, such as volcanoes (opposite is centripetal). Probably the most commonly used water sampler is known as a CTD/rosette: it is a framework designed to carry 12 to 36 sampling bottles (typically ranging from 1.2- to 30-liter capacity) and a conductivity/ temperature/ depth sensor that sends information to the laboratory so that the water bottles can be closed selectively as the instrument ascends.

These waves move through water shallower than 1/20 their wavelength, These waves travel though water deeper than 1/20 but shallower than 1/2 their wavelength. At the instrument's maximum depth of 1,000 to 6,500 feet (300 to 2,000 meters), the wire breaks. =acid rain Movement of saltwater into freshwater aquifers in coastal and inland areas as groundwater is discharged/withdrawn faster than it is recharged by processes like precipitation. About 3.5% of the weight of seawater comes from the dissolved salts; in a cubic mile of seawater, the weight of the salt in the form of sodium chloride would be about 120,000,000 tons. Drifting sediment traps are used to study surface layer sedimentation, and such instruments as an acoustic backscattering device for collecting long-term data on plankton distribution are mounted on drifting buoys.
