Sea level the warmer water expands. For at least the last 100 years, sea level has been rising at an average rate of about per year. Most of this rise can be attributed to the increase in temperature of the sea and the resulting slight thermal expansion of the upper of sea water. Additional contributions, as much as one-quarter of the total, come from water sources on land, such as melting snow and glaciers and extraction of groundwater for irrigation and other agricultural and human uses. Pilots can estimate height above sea level with an altimeter set to a defined barometric pressure.

Other releases comprised recitations of the unpublished "Earth Ritual" poems collection and two music tapes, "Blueprints from the Cellar" Volumes 1 and 2, which contained home demos of songs, some of which would be released in completed form on the albums "Freq" and "Test Tube Conceived".
