From: Bob Denton > >Ice Floats! > Yes, ice floats on salt water. If the water is warmer than the ice, the ice melts producing cold water. Cold water and sea water can mix. The density of water increases as temperature decreases. Perhaps it is possible, with the right conditions for the mixing process to produce water that is slightly denser than the water around it. The slightly denser, cooler and less saline water would then sink. the density tables for sea water as a function of salt content and temperature led me to speculate that this process might occur. so i'm trolling to see if there are observations of hail over the ocean... because i can't find reports of it in journals, on the web, or through discussions with a couple of weather/oceanographer types...by communicating with folks with time at sea in lots of locations, perhaps i'll know more about hail at sea. a former American Meterological Society President discussed with me that he has seen a NOAA salinity time series from a sensor at 30 ft that has a fresh water feature. note that fresh water feature means that the salinity dropped from 34 parts per 1000 to 32/1000. Not a huge change, but noteable in the data record. he claims it is due to rain. i think it was more likely to have been a hail storm. what the hail, talk's cheap. and ice floats. bliven *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************Received on Thu Jan 21 1999 - 15:25:57 PST
