This NSF continental drilling planning grant seeks to establish a temporary seismic array in the vicinity of the Lake Izabal Basin (LIB) in eastern Guatemala to prepare for a deep drilling project in the basin, providing information on faults and seismicity required for drilling safety and to optimize the location of several accompanying shallow boreholes. The LIB contains the longest known continental records of tectonics, climate, and environmental change in the northern neotropics. The LIB developed around 12 million years ago and today holds more than 4 km of sediment, making it an ideal location for an International Continental Scientific Drilling Program (ICDP) project. Additionally, this award will provide for meeting with local drilling companies to establish the technical and procedural requirements necessary for successful continental scientific drilling operations and enable early engagement with local communities and governmental and educational institutions to ensure smooth drilling planning, permitting, and operations. Drilling and coring in continental settings through continental scientific drilling programs has provided answers to compelling scientific questions that allow us to forecast how global Earth Systems might behave in the future. Long and continuous records from continental regions are rare and several areas of the world remain unexplored. One of these areas is Central America, where geography, topography, geology, and biology have influenced several Earth System processes through geologic time. The LIB, located in eastern Guatemala, is at a nexus location to record all these processes in its sedimentary record. The LIB is a pull-apart basin along the North American (NA) and Caribbean (CA) plate boundary with continuous sediment accumulation since the Miocene (~ 12 Ma), in some places with accumulated sediment thickness of over 4 km. The Lake Izabal Basin Research Endeavor drilling project focuses on: 1) investigating the longest known continental sedimentary record from the northern Neotropics to investigate tropical hydroclimate, biological interchanges, paleoseismic events, and volcanic activity since the Miocene; and 2) establishing a seismic observatory along the NA-CA plate boundary. This NSF planning grant provides the opportunity to obtain necessary key preliminary information to guarantee the success of the drilling project. These include: 1) deployment of a temporary seismic array to help identify active faults in the region; 2) establishment of connections with drilling companies in the country, including discussing technical requirements for soft-sediment coring and safety considerations; 3) early engagement with local communities, organizations, policymakers, and stakeholders to ensure smooth drilling planning, permitting, and operations; and 4) producing educational material and meet with educational organizations to help us plan for the drilling project and spread and multiply our outreach efforts in Guatemala.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.

NSF大陆钻探计划赠款旨在在危地马拉东部的伊扎巴尔湖盆地（LIB）附近建立一个临时的地震阵列，以准备盆地中的深入钻井项目，提供有关钻井安全性所需的缺陷和地震性信息，以优化几个伴随着伴随的浅滩的位置。 LIB包含北部新型新兴技术中最长的构造，气候和环境变化的大陆记录。 LIB大约在1200万年前开发，如今拥有超过4公里的沉积物，使其成为国际大陆科学钻探计划（ICDP）项目的理想场所。此外，该奖项将授予与当地钻探公司会面，以建立成功的大陆科学钻探行动所必需的技术和程序要求，并能够与当地社区以及政府和教育机构进行尽早参与，以确保平稳的钻井计划，许可和运营。通过大陆科学钻探计划在大陆环境中进行钻探和训练，为引人入胜的科学问题提供了答案，使我们能够预测全球地球系统将来如何行事。大陆地区的长期和连续的记录很少见，世界上几个地区仍未开发。这些领域之一是中美洲，地理，地形，地质和生物学通过地质时代影响了几个地球系统过程。位于危地马拉东部的LIB位于Nexus的位置，在其沉积记录中记录所有这些过程。 Lib是沿北美（NA）和加勒比海（CA）板块边界的一个小型盆地，自中新世（〜12 mA）以来，在某些地方的沉积物厚度超过4 km。 伊扎巴尔湖盆地研究努力钻探项目的重点是：1）研究北部新型新型北部已知的大陆沉积记录，以研究自中新世以来热带氢化气候，生物互换，古糖震动事件和火山活动； 2）沿着Na-Ca板块边界建立地震天文台。这项NSF计划赠款提供了获得必要的关键初步信息的机会，以确保钻探项目​​的成功。其中包括：1）部署临时地震阵列，以帮助识别该地区的主动故障； 2）与该国的钻井公司建立联系，包括讨论有关软化加油和安全考虑的技术要求； 3）与当地社区，组织，政策制定者和利益相关者的早期互动，以确保平稳的钻探计划，许可和运营； 4）生产教育材料并与教育组织会面，以帮助我们为钻探项目计划，并在危地马拉进行宣传并繁殖我们的外展工作。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的审查标准通过评估来进行评估的。
