402 Words2 Pages
In the article “Sea-Level Rise Gives Clue to Big Chill” by John Roach, Roach interviews different scientists to see how freshwater impacts our oceans. Previous studies have calculated the amount of freshwater dumped into the North Atlantic based on the size of the ancient Lake Agassiz. Tornqvist and his colleagues were able to get a read on the sea-level rise associated with the 8.2 ka event by studying cores of sediment from the Mississippi River delta in Louisiana. The team retrieved two cores, one with a peat layer dated to just before the 8.2 ka event and one with a peat layer dated to just after. Renssen, the climate modeler, said the study results will help scientists in the climate research better determine the thermohaline circulation,
