When the Costa Concordia struck a rock and capsized off the coast of Isola del Giglio, Italy, on the night of January 13, 2012, the Mediterranean water temperature was approximately 14°C (57°F). While this might not seem "freezing" compared to the Arctic, it is cold enough to induce cold water shock and hypothermia within a relatively short period. For passengers who were forced to swim or were submerged while waiting for rescue, the temperature was a critical survival factor. Exposure to 14°C water can cause a person to lose dexterity in their fingers within 10–15 minutes, making it difficult to grab onto ropes or life vests. The search and rescue operations were further complicated by these temperatures, as the survival window for anyone trapped in air pockets or submerged in the lower decks was drastically shortened by the rapid loss of body heat to the surrounding sea.
