SGER: Exploratory Research to Calibrate a High-Altitude Lacustrine Geochemical Record to the Instrumental Record of Western Tropical Pacific Convection

该奖项是在探索性研究小额拨款（SGER）计划的支持下，将为西太平洋对流系统的低层自由对流层建立一个独特的代用同位素记录。这个系统在热带太平洋的气候中起主导作用。关岛湖的研究地点毗邻太平洋暖池，位于巴布亚新几内亚Huon半岛高原海拔3600米（南纬6度，东经147度）。研究人员将生成并校准关岛湖碳酸盐沉积物中氧-18和碳-13的同位素记录，以及热带太平洋西部历史大气探测中温度、湿度和风的仪器记录。考虑这一奖励的理由是验证热带太平洋西部对流层下层的第一个高海拔同位素记录和发展该对流系统的第一个代理垂直探测的高风险挑战。

This award, under the auspices of the Small Grants for Exploratory Research (SGER) program, will establish a unique proxy isotopic record for the lower free troposphere of the western Pacific convection system. This system plays a dominant role in the climate of the tropical Pacific. The study site on Lake Guam is situated adjacent to the Pacific warm pool and at an elevation of 3600 meters on the high plateau of the Huon Peninsula, Papua New Guinea (6 degrees S and 147 degrees E). The researcher will generate and calibrate isotopic records of Oxygen-18 and Carbon-13 from carbonate sediments in Lake Guam to instrumental records of temperature, humidity, and winds from historical atmospheric soundings in the western tropical Pacific. The rationale for considering this award is the high-risk challenge of validating the first high altitude isotopic record of the lower troposphere in the western tropical Pacific and developing the first proxy vertical soundings of this convection system.
