Twenty two sailors are feared dead in the frigid waters of the Antarctic Ocean, where a South Korean fishing boat has sunk.

The Number One In-Sung sank nearly halfway between New Zealand and Antarctica. Twenty survivors have been found and are now on another fishing vessel. Anyone who fell into such waters would typically be dead in ten minutes without special suits or life jackets, though nearby fishing boats launched a frantic search in hopes some made it into life rafts.

The South Korean boat had 42 people on board when it sank: eight South Korean, eight Chinese, eleven Indonesians, 11 Vietnamese, three Filipinos and one Russian. Four Chinese sailors are missing while four others were rescued.The rescue center says it's still not sure what caused the sinking or why no distress communication was received.

Kim Jeong-do, Director of Insung, said, "The water logging hull is suspected as a cause of the accident. South Korean vessels Hongjin 707, Jungwoo 2, Jungwoo 3 and two New Zealand vessels are on the rescue mission. Also the New Zealand government has mobilized an aircraft to search for the missing."
