Гольфстрим
Monthly charts of the Gulf Stream have been published by the US Naval Oceanographic in "Gulf Stream Monthly Summary" from 1966 to 1974, and by the US National Oceanic and Atmospheric Administration in "Gulf Stream" from 1975 to 1980 and "Oceanographic Monthly Summary" from 1981 until 1994. Later charts have been obtained from the US Navy. Each chart gives a snap-shot of the currents path at the end of the month. The monthly charts were analysed by the procedure described in Taylor.
