RICE ice core nitrate data for the last glacial period (83-26 ka BP)
Roosevelt Island Climate Evolution (RICE) ice core non-sea salt calcium (nssCa) and nitrate (NO3) data, covering last glacial period from 83000-26000 years BP are presented here. RICE is a 764-m long ice core retrieved from Roosevelt Island, a coastal dome in the vicinity of Ross Sea, West Antarctic...

Roosevelt Island Climate Evolution (RICE) ice core non-sea salt calcium (nssCa) and nitrate (NO3) data, covering last glacial period from 83000-26000 years BP are presented here.
