6.According to paragraph 4, ice shelf cores helped scientists explain the formation of green icebergs by showing that A. the ice at the bottom of green icebergs is bubble-free ice formed from frozen seawater. B. bubble-free ice is found at the top of the ice shelf ...
R. et al. Ocean heat drives rapid basal melt of the Totten Ice Shelf. Sci. Adv. 2, e1601610 (2016). Presents observations from the calving front of Totten Glacier, East Antarctica, that confirm that warm water enters the ice-shelf cavity through a deep channel, driving high basal-melt ...
Based on our records, we cannot confirm nor rule out disintegration of such an ice shelf as a contributor to freshening at the onset of TII, leading the retreat of Northern sectors of the EIS. However, the modest magnitude of Arctic shelf ice volume suggests that this cannot be the only ...

The ice sheet may also have advanced into the Lake Ontario basin during Stage 4. The position of the northern margin of the Laurentide Ice Sheet during Stage 4 is not known, but it remained an unknown distance behind its maximum position reached during Stage 5. Cores from Baffin Bay ...
因此,芝罘剖面末次间冰期—末次冰期黄土-古土壤沉积序列受东亚冬夏季风格局影响,远源与近源物质交替混杂,各CEM值是探讨该区域气候变化的有效指标。 5. 结论 (1) 芝罘剖面可分为MIS5和MIS4两个阶段。其中,MIS5又可划分为MIS5e(118.5~124.9kaBP)、MIS5d(105.2~118.5kaBP)、MIS5c(94.7~105.2kaBP)、MIS5b(83.4...
More recently, ice shelf basal melt73,157, surface melt56, and subglacial meltwaters15,74,144 from the ice sheet have been proposed as potential sources of Fe to the Southern Ocean, but these melt (and Fe) inputs are likely limited to the coastal zone15. Examination of records of IRD ...
