Excerpt from the expedition summary:
The northeast coast of the United States is perhaps the best understood example of an offshore freshwater system, and multiple studies have been undertaken to determine the origin and volume of offshore freshwater. Coring and sampling the subseafloor offshore Massachusetts, USA, will provide data for understanding the processes driving emplacement of freshwater lenses offshore New England and elsewhere globally, and lead to a better understanding of this worldwide hydrogeological phenomenon. This is essential for protection and sustainable management of offshore freshwater systems and for better understanding biogeochemical and elemental cycling in continental shelf environments.
With regard to the potential freshwater resources (from the Nantucket Current):
“I’m just excited about the science, and that finally, after all these years, someone’s trying to get the truth,” said Nantucket Water Department director Mark Willett. “Computers predicted it. Everybody thinks it’s there. These guys are the first ones in the world who are going to go drill a hole and prove it.”
Willett and (lead scientist Brandon) Dugan are particularly intrigued by the possibility that the offshore freshwater aquifer could be connected to a lower, untapped aquifer beneath Nantucket that Willett calls “ancient glacier lake Nantucket.”
“If it is connected and it’s young water that’s being recharged actively today, that’s really exciting, because it’s a renewable source,” Dugan said.
