Ice on Galway Docks

Saturday, January 30, 2010

The photo above showing ice at the docks in Galway, Ireland was captured in the early afternoon of January 9, 2010. The Atlantic coast of Ireland hasn't experienced seawater freezing in its dock area since the early 1980s. The freezing temperature of seawater varies according to the salinity of the water: the greater the concentration of salts, the lower the initial freezing temperature. Seawater typically has a salinity of at least 35 parts per thousand or 3.5 percent. Given this level of salinity water will normally freeze at a temperature of approximately 28.6 degrees F or -1.9 degrees C.
