Description:
The 320 cm long gravity core E25 (Arc7-E25, 179.4°E, 79.0°N; 1200 m) was retrieved from the southernmost Mendeleev Ridge during the 7th cruise of the Chinese Arctic expedition on the R/V Xue Long in 2016. In combination with the 14C ages, U-Th series measurements analyzed at Geotop-UQAM in 2019 have been used to set up the chronostratigraphy. In addition, TOC and its 13C, grain size distribution, and bulk mineralogy have also been analyzed to evaluate the resilience of the East Siberian Ice Shelf/Sheet and to provide a distinct paleoceanographic view of the western Arctic Ocean.
