Operates: On a cable or line (free fall) or by hand without a messenger Exchanges across the air-sea interface, including heat and fresh water, couple the ocean and atmosphere and are of major interest in studies of global climate. For many years, current meters have been attached to moorings as described above, left for a time to collect data, and then retrieved. As scientists try to understand movement of materials through the oceanic system, they moor sediment traps at various depths for many months to collect samples of particles sinking through the water column. These springs slowly let water out through loose soil or rock and are often found in land depressions or low in valleys. The largest water bottles, called Gerard barrels, collect 250 liters. Near the equator, the tropics receive lots of rain constantly, which helps decrease the salinity of the surface water in that region. nick point basically this just refers to a steep and rapid change in gradient; this is usually marked by a waterfall. endobj *GHQumI ( p:7+
