  3. TIDE CURRENT • Current = the horizontal movement of a body of water. • Causes: • Gravitational effects of sun and moon • Heating and cooling of Earth’s atmosphere • Winds blowing across the ocean’s surface • Changes in salinity due to rain and evaporation • The Coriolis effect Set - the direction of the currents motion Drift - the velocity of the current Set & Drift represent the vector added to ship’s motion by the current

  6. 1410 DR 1400 DR 7th Feb. HW LW BA TIDE DIAMOND SET : 2650 Drift : 2,6 Knot For Spring Tide 1,3 Knot Neap Tide We will check Mean Range and Actual Rangefor Actual Drift Proceed

  7. 1410 DR 1400 DR 7th Feb. BA TIDE DIAMOND SET : 2650 Drift : 2,6 Knot For Spring Tide 1,3 Knot Neap Tide MEAN RANGES Springs = 6 m Neaps = 3,2 m ACTUAL RANGE = 5,5 m We will compare ranges and make a interpolation
