In situ Magnesium/Calcium (Mg/Ca) and oxygen isotope (d18O) measurements in Neogloboquadrina pachyderma shells collected in 1999 by a MultiNet tow from different depth intervals in the Fram Strait
This dataset includes chemical and isotopic measurements on shells of the planktic foraminifera Neogloboquadrina pachyderma sinistral, collected by plankton tows (MultiNet) from eight stations across the Fram Strait (sites ARK XV/2 77-84). The sampled depth intervals are 0-50 meters (m), 50-100 m, a...
