| 内容記述 | To determine annual layers for reconstructing the past environment at annual resolution from ice cores, we employed snow-stake data back to 1972, tritium content, solid electrical conductivity measurements (ECM) and stratigraphic properties for the 73 m ice core at the H72 site, east Dronning Maud Land, Antarctica. The average annual surface mass balance at H72 is 307 mm a-1 w.e. during the last 27 years from continuous accumulation data, 317mm a-1 w.e. according to the densification model and 311mm a-1 w.e. according to the average surface mass balance for 167 years based on annual-layer counting. The ECM age is closely coincident with tritium age, and corresponds with the snow-stake record back to AD1972 from the surface to 15m depth. The H72 ice core is dated as AD1831by ECM at 73.16m depth. The time series of yearly surface mass balance at H72 shows an almost constant 311mm a-1 w.e. for the last 167 years. The oxygen-isotope records indicate a significant trend to lower values, with negative gradient of 1.7 (100 years)-1. | |||||
