The LIBRE (Lake Izabal Basin Research Endeavor) Scientific Drilling Workshop provides the opportunity to promote and explore science in two broad and interdisciplinary fields regarding Lake Izabal Basin (LIB) located along the southern border of the North American Plate in Guatemala. First, the basin formed along a fault analogous to the San Andreas Fault in California. Despite significant scientific efforts to understand the likelihood of such faults to rupture and cause significant structural damage and loss of human life, there are still fundamental scientific questions that remain unsolved. This workshop facilitates science experts coming together to discuss current knowledge and remaining unsolved questions of this plate boundary. Second, drilling the sediments in the basin would provide the opportunity to answer questions related to climatic, biologic, ecologic, and volcanic changes in the tropics for 1 million years. The workshop convenes experts from around the world to discuss these research endeavors and to recommend a scientific plan that results in significant contributions to the Earth Sciences and society. The LIBRE (Lake Izabal Basin Research Endeavor) Scientific Drilling Workshop provides a forum for scientists and students to discuss the scientific importance and societal significance of drilling and coring the Lake Izabal Basin (LIB), an active pull-apart basin that developed along the North American and Caribbean plate boundary. Drilling the northern fault of the plate boundary and collecting cores from the thick sedimentary cover in the LIB can improve understanding of regional tectonics and associated geohazards along strike-slip plate boundaries; paleoclimate and tropical feedback on climate change across multiple glacial-interglacial cycles; associated paleoecological and paleobiological changes; and geohazards associated to the Central American Volcanic Arc. Further, discussions on climate, biology, ecology, and volcanology can lead to development of specific scientific questions related to the response of tropical ecosystems to environmental changes. Funds for the workshop ensure that students from groups typically excluded from geosciences and early career scientists can attend the workshop and participate in the discussions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

LIBRE （Lake Izabal Basin Research Endeavor）科学钻探研讨会为促进和探索位于危地马拉北美板块南部边界的Izabal湖盆地（LIB）的两个广泛和跨学科领域的科学提供了机会。首先，这个盆地是沿着一条类似于加州圣安德烈亚斯断层的断层形成的。尽管科学上做出了巨大的努力来了解这种断层破裂的可能性，并造成重大的结构破坏和人员伤亡，但仍有一些基本的科学问题尚未解决。本次研讨会促进科学专家聚集在一起，讨论当前的知识和尚未解决的问题，这一板块边界。其次，钻探盆地中的沉积物将提供机会回答与100万年来热带地区气候、生物、生态和火山变化有关的问题。研讨会召集了来自世界各地的专家来讨论这些研究工作，并推荐一个对地球科学和社会有重大贡献的科学计划。LIBRE （Lake Izabal Basin Research Endeavor）科学钻探研讨会为科学家和学生提供了一个讨论Izabal湖盆地（LIB）钻探和取心的科学重要性和社会意义的论坛，LIB是一个沿北美和加勒比板块边界发展的活跃的拉分盆地。通过对板块边界北部断裂的钻探和对LIB厚沉积盖层的岩心采集，可以提高对走滑板块边界区域构造和相关地质灾害的认识；多个冰期-间冰期旋回对气候变化的古气候和热带反馈相关的古生态和古生物学变化；以及与中美洲火山弧有关的地质灾害。此外，关于气候、生物学、生态学和火山学的讨论可以导致与热带生态系统对环境变化的反应有关的具体科学问题的发展。研讨会的资金确保来自通常被排除在地球科学和早期职业科学家之外的群体的学生能够参加研讨会并参与讨论。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
