Document Summary

Lecture 8 notes: coasts are changing, a million people live in a few feet of high tide, global sea level has change throughout the years, land/sea topography, polar ice caps, seawater density, other factors. River flow rates: between 0 ad and 1900 ad sea level rose about . 1 meter (very little, relative sea level- height of ocean relative to land elevation at a location. Salinity: technology used to detect sea level change and the things that cause it (ice melting, sea temperatures), satellites measure, ocean topography, earth"s g(cid:396)a(cid:448)ity field, sea surface temperature, ocean salinity. Ice sheets: satellites include: jason 1, jason 2, topex. All the above: temperature, salinity, currents: temperature anomaly, reference temp is always changing, measure change of temperature relative to the long term average, measure above and below the mean (box, mean temperature, difference since the measurement started.
