This award, under the auspices of the Small Grants for Exploratory Research (SGER) program, will improve and extend the radiocarbon calibration program (i.e., CALIBRATION) used in the field of paleoclimatology to provide a temporal control for climatic events. Dating geo-biologic samples to establish age control is critical to paleoclimatic investigations. The CALIBRATION program (i.e., CALIB) is fundamental to this enterprise. The CALIB program needs to be periodically updated to take advantage of the latest developments in geochemical measurements and understanding of carbon reservoir effects on radiocarbon dating. This award will help researchers improve the calibration across several critical time periods in the Holocene and Pleistocene time periods that are at the forefront of paleoclimate research intensely supported by the NSF through many Programs and across Directorates. In addition to updating the program, the researcher team will also modify the CALIB software so that it is compatible with Microsoft Windows and Macintosh operating systems. U.S. and non-U.S. researchers, on collaborative international projects supported in part by the National Science Foundation, use the CALIB program extensively. As such, CALIB has great utility and great impact by helping the research community integrate its research efforts.

该奖项在探索性研究（SGER）计划的小额赠款的支持下，将改进和扩展放射性碳校准计划（即，在古气候学领域中用于提供气候事件时间控制的校准。 确定地质生物样品的年代以建立年代控制对于古气候调查是至关重要的。 校准程序（即，CALIB）是这项事业的基础。 CALIB计划需要定期更新，以利用地球化学测量的最新进展和对碳库对放射性碳测年影响的理解。 该奖项将帮助研究人员改善全新世和更新世时期几个关键时期的校准，这些时期是NSF通过许多计划和跨部门强烈支持的古气候研究的最前沿。 除了更新程序外，研究小组还将修改CALIB软件，使其与Microsoft Windows和Macintosh操作系统兼容。 美国和非美国的研究人员，在部分由国家科学基金会支持的国际合作项目中，广泛使用CALIB程序。 因此，CALIB通过帮助研究社区整合其研究工作而具有很大的实用性和影响力。
