7.4 Ice cover formation on River Irtysh, Russia

Q. " How ice cover is formed under the influence of air/water temperatures and water currents ? "

A.

For average body water temperature = 4 C and no-wind conditions.
Water - blue, ice - red.

Ambient air temperature = - 1 C
Ambient air temperature = - 3 C
Ambient air temperature = - 5 C
Ambient air temperature = - 6 C
Ambient air temperature = - 7 C
Ambient air temperature = - 8 C
Ambient air temperature = - 9 C
Ambient air temperature = - 10 C
Ambient air temperature = - 11 C
Ambient air temperature = - 12 C
Ambient air temperature = - 13 C
Ambient air temperature = - 14 C
Ambient air temperature = - 15 C
Ambient air temperature = - 16 C
Ambient air temperature = - 17 C
Ambient air temperature = - 18 C
Ambient air temperature = - 19 C

7.5 Oil slick movement underneath of fragmentary ice cover in windy weather.

• River Saint Clair of Great Lakes, Canada
• Instantenous spill of 500 m^3
• Wind of 5 m/sec from right bottom corner
