For the guys arguing about benefits/problems with chart plotters, this story just came out- real interesting:
Scientists 'undiscover' South Pacific island - CNN.com
CNN) -- An international scientific expedition has revealed a South Pacific island roughly the size of Manhattan and clearly marked on online maps and marine charts
does not, in fact, exist.
The 'undiscovery' of the island -- which until now was midway between Australia and New Caledonia -- highlights how much there still is to learn about the oceans, scientists say.
"We saw this mysterious island on all the scientific maps and weather maps but not on this one navigational chart that was on our ship," Ph.D student Sabin Zahirovic, part of the research team on board the RV Southern Surveyor, told CNN.
"So we decided to go see if it was actually there."
The undiscovery was made during the ship's voyage this month. Although the team had originally planned to check out the existence of the island during the day, they had arrived at the location of the island at night due to a navigational error.
"We were watching all of our depth-sounding equipment. Luckily for us the sea floor turned out to be very deep there," said Zahirovic, who is studying the tectonic evolution of the eastern Coral Sea.
The implications are significant
Although the undiscovery of the island was not part of the original research mission of the international team of scientists led by University of Sydney's Dr. Maria Seton, the implications of the wrong maps are significant.
"All the scientific cartography relies on these maps, and numerical simulations of waves and currents depend on size of these land forms," said Zahirovic.
"It just goes to show the oceans are so underexposed. It's actually really shocking that we haven't not found more islands."
Can anyone pull up this on their chart plotter to see if it shows up, I will try on mine in next few days. Island is called both Sandy Island by Google Maps and Sable Island on others?
