Geochemical and isotopic data from the Mendeleev Ridge core HLYHLY0503-11MC8 ...
The data are from samples of core HLYHLY0503-11MC8, which was collected onboard the American research vessel Healy on the Mendeleev Ridge during the Healy-Oden Trans Arctic Expedition (HOTRAX) in summer 2005 (Darby et al., 2005). The core site is located at 83°07.7300N, 174°41.5700W (water depth = 2...

| Summary: | The data are from samples of core HLYHLY0503-11MC8, which was collected onboard the American research vessel Healy on the Mendeleev Ridge during the Healy-Oden Trans Arctic Expedition (HOTRAX) in summer 2005 (Darby et al., 2005). The core site is located at 83°07.7300N, 174°41.5700W (water depth = 2570 m). The data include dolomite and total carbonate, stable isotope data in planktic foraminifers and bulk (18O and 13C), sand and clay content, in addition to 230Thxs and 231Paxs. Data are reported vs. depth (cm). Methods : The multicore was sampled at half-centimeter intervals. The sediment was dried and ground in an agate mortar. Particle-size analyses were performed from wet sieved sediment in the < 2 mm fraction after disaggregating in an ultrasonic bath for 90 seconds. The disaggregated sediment was analyzed with a laser-diffraction particle-size analyzer (LS13320, Beckman-Coulter™). Laser calibration was verified before and after analyses using three standards Latran 300-0.3 mm, G15-15 mm, and ... |
