An iceberg has been spotted from the New Zealand shore for the first time in living memory, and scientists are trying to determine where it and several other giant chunks drifting in the country's waters orginated from. Last year, icebergs were seen in New Zealand water for the first time in 56 years, but couldn't be seen from the shore. This year one was visible from Dunedin on South Island on Thursday. It has since moved away, driven by winds and ocean currents. The floating ice blocks have become a tourist attraction, as sightseers pay up to 500 New Zealand dollars (US$332; euro252) each to fly over the icebergs. Theories about where on the Antarctic coastline the icebergs originated have gripped the science community since they were first spotted. National Institute of Water and Atmospheric Researc, says the iceberg could not spefically be linked to global warming.
