"At the moment the water temperatures of the Marmara sea for certain days since June of last year is of interest." Any oceanographic institute there? How about a fishing agency? Because the Sea of Marmars is semi-enclosed, you may have some unusual local issues. A steady wind from one side will "roll" the water. For example, a wind from the north will force warm surface waters to the southern shore and dredge up deep, cold water on the northern shore. This can occur on a daily cycle. This sort of thing is common also on the Great Lakes in the US. On some days in Chicago in June, the day will start out hot and humid, and the lake water warm. As the normal mid-day wind from the west kicks up, the warm surface waters are blown east in the afternoon. Then cold water from deeper parts of the lake will take its place, setting up "lake effect" weather in the early evening. This brings chilly breezes from the east and possibly damp fog into the city. The cycle can complete in the middle of the night pushing the cold air back out. Sometimes this cycle --hot and sunny mid-day, chilly and foggy early evening, warm clearing middle night-- can last for weeks. One source for SST (sea surface temperature) data is here: http://www7320.nrlssc.navy.mil/global_nlom32/med.html You could average the temps for the Black Sea and the Aegean. Maybe?? But I wouldn't depend much on this. -FER --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
