Document Summary
How the water is being affected by the wind and the spinning of the earth = ekman. Oceanic common water - deep current merged at the bottom of the pacific and indian oceans. Monsoons are a reversal of the wind direction. Monsoons are important because that normally causes changes in where rain will fall. Plastics and other waste accumulate at trash islands in stagnant part of gyres. El nino is a deviation from normal winds (always seen around christmastime in the. Three possible situations: normal winds, el nino (weaker), la nina (stronger) Waves = energy transfer between neighboring particles. Longitudinal waves: push-pull/side to side , particles move same direction as particles. Transverse waves: up and down , waves move the particles orthogonally. Wavelength = how fast the wave is moving. Deep water waves: when depth of water > l/2. Shallow water waves: when depth of water < l/2. Tsunami: mostly caused by sudden changes to the ocean floor.
