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.

美国国家科学基金会的这项大陆钻探规划拨款旨在在危地马拉东部伊萨瓦尔湖盆地 (LIB) 附近建立一个临时地震台阵，为该盆地的深钻项目做准备，提供钻探安全所需的断层和地震活动信息，并优化几个伴随浅井的位置。 LIB 包含已知最长的北部新热带地区构造、气候和环境变化的大陆记录。 LIB 形成于大约 1200 万年前，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) 项目的理想地点。此外，该奖项还将提供与当地钻井公司会面的机会，以确定成功的大陆科学钻井作业所需的技术和程序要求，并促进与当地社区、政府和教育机构的早期接触，以确保钻井规划、许可和运营的顺利进行。通过大陆科学钻探计划在大陆环境中进行钻探和取芯，为引人注目的科学问题提供了答案，使我们能够预测全球地球系统未来的表现。来自大陆地区的长期且连续的记录非常罕见，世界上的一些地区仍未被勘探。这些地区之一是中美洲，那里的地理、地形、地质和生物学在整个地质时期影响了地球系统的多个过程。 LIB 位于危地马拉东部，处于沉积记录中记录所有这些过程的枢纽位置。 LIB是沿北美（NA）和加勒比（CA）板块边界的拉分盆地，自中新世（~12 Ma）以来沉积物持续积累，在一些地方沉积物厚度超过4公里。 伊萨巴尔湖盆地研究奋进钻探项目的重点是：1）调查北部新热带地区已知最长的大陆沉积记录，以调查中新世以来的热带水文气候、生物交换、古地震事件和火山活动； 2）沿 NA-CA 板块边界建立地震观测站。美国国家科学基金会的这项规划拨款提供了获得必要的关键初步信息的机会，以保证钻探项目的成功。其中包括：1）部署临时地震台阵，以帮助识别该地区的活动断层； 2）与国内钻井公司建立联系，包括讨论软沉积物取芯的技术要求和安全考虑； 3) 尽早与当地社区、组织、政策制定者和利益相关者接触，以确保钻井规划、许可和运营顺利进行； 4) 制作教育材料并与教育组织会面，帮助我们规划钻探项目，并扩大和扩大我们在危地马拉的外展工作。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
