GEOSC 040 Lecture Notes - Lecture 19: T Wave, Wind Wave, Eutrophication
Document Summary
Eutrophication- an environmental nutrient excess that leads to severe reduction of dissolved oxygen: occurs in restricted bays including bodies of water as large as the. Hypoxia- complete loss of dissolved oxygen in seawater: each organism has its own tolerance. Nearly all waves in the ocean are produced by wind (99%) Capillary waves become gravity waves as their wavelength exceeds 1. 74 centimeters: they continue to grow as long as the wind above them exceeds their speed. A wave piles up water and then lets it flow away, dictated by gravity. T= wave period in seconds (time for one wavelength to pass) H= wave height (distance from crest to trough) in meters. T = wave period in seconds (time for one wavelength to pass) D= depth of water column in meters. N = water surface displacement from swl. Water particle motion vs. motion of the wave energy.
