Weddell Sea icebergs: 5 years of observations
Since 1999, 59 icebergs have been tagged with GPS buoys in the Weddell Sea to enable monitoring of their position. The icebergs chosen were of small to medium size, with a few icebergs larger than 10 km associated with the calving of icebergs A38 and A43 from the Ronne Ice Shelf. The majority of ice...
