Continuous Greenland Ice Sheet Project 2 glaciochemical measurements, Greenland Ice Sheet, 2019.

The overall goal of the project is to use sophisticated atmospheric models together with ice-core records the to improve understanding of variations in past climate, including during the last glacial period. To provide state-of-the-art aerosol and other ice-core records representative of the last glacial, continuous, high-depth-resolution measurements were made on ~104 meters(m) of archived Greenland Ice Sheet Project 2 (GISP2) ice spanning Dansgaard-Oeschger events 10, 11, 12. The measurements were made using the unique, well-established continuous ice core analytical system at the Desert Research Institute in Reno, Nevada (NV) during December, 2017, with data processing and strict quality control/quality assurance procedures completed in January, 2019. The analytical system consists of a broad range of instruments including two Element2, Inductively Coupled Plasma Mass Spectrometers operating in parallel.

本项目的总体目标是结合先进的大气模型与冰芯记录，加深对包括末次冰期在内的过去气候变化的理解。为获取能够代表末次冰期的最先进气溶胶及其他冰芯记录，研究团队对覆盖丹斯果德-厄施格（Dansgaard-Oeschger）事件10、11、12的约104米存档格陵兰冰芯计划2（GISP2）冰芯开展了连续、高深度分辨率测量。本次测量于2017年12月在内华达州里诺市的沙漠研究所（Desert Research Institute），依托一套独特且成熟的连续冰芯分析系统完成；数据处理与严格的质量控制/质量保证流程则于2019年1月全部完成。该分析系统包含多种仪器设备，其中包括两台并行运行的Element2型电感耦合等离子体质谱仪（Inductively Coupled Plasma Mass Spectrometers）。
