The International Ocean Discovery Program (IODP) aims at studying the seafloor through scientific drilling in order to improve our understanding of past oceans and subseafloor processes. IODP was launched in October 2013 and is the successor of earlier marine scientific drilling programs including the Deep Sea Drilling Project (DSDP, 1968 - 1983), the Ocean Drilling Program (1983 - 2003) and the Integrated Ocean Drilling Program (IODP, 2003-2013). The overall objectives of the new program are summarized in the science plan "Illuminating Earth´s Past, Present and Future". This science plan comprises four major themes subdivided into 14 challenges which in turn address new, forward-looking questions, methods and models: 1) "Climate and Ocean Change": One of the most important scientific challenges is to better understand rates and causes of global climate change and its consequences. Studying paleoclimate archives from the deep-sea will allow better constraining past climate change including the sensitivity of ice sheets and sea-level. This in turn can help to reduce uncertainties in predicting future climates. 2) "Biosphere Frontiers": This theme addresses the biosphere below the sea-floor, specifically to understand the global importance of microbial communities and its participation in the global carbon cycle, but also the physical and chemical limits for reproduction and dispersal. Another major challenge in this theme is the study the sensitivity of marine ecosystems and biodiversity to environmental change. 3) "Earth Connections": Within this theme geochemical exchange processes between the subsurface, specifically the upper mantle, and the exogenic system are addressed. These processes include the interaction of the Earth surface and subduction zones as well as oceanic crust production and alteration. 4) "Earth in Motion": This theme aims at short-term geodynamic processes that are of direct societal relevance like seismogenic zones, landslides and tsunamis. In addition, this theme also facilitates studies of sub-seafloor carbon sequestration and the installation of subseafloor observatories.

国际海洋发现计划（IODP）旨在通过科学钻探研究海底，以提高我们对过去海洋和海底过程的理解。IODP于2013年10月启动，是早期海洋科学钻探计划的继任者，包括深海钻探项目（DSDP, 1968 - 1983），海洋钻探计划（1983 - 2003）和综合海洋钻探计划（IODP, 2003-2013）。这项新计划的总体目标在“照亮地球的过去、现在和未来”科学计划中得到了总结。该科学计划包括四个主要主题，分为14个挑战，依次解决新的、前瞻性的问题、方法和模型：1)“气候和海洋变化”：最重要的科学挑战之一是更好地了解全球气候变化的速度、原因及其后果。研究深海的古气候档案可以更好地约束过去的气候变化，包括冰盖和海平面的敏感性。这反过来又有助于减少预测未来气候的不确定性。2)“生物圈前沿”：该主题涉及海底以下的生物圈，特别是了解微生物群落的全球重要性及其在全球碳循环中的参与，以及繁殖和扩散的物理和化学限制。这一主题的另一个主要挑战是研究海洋生态系统和生物多样性对环境变化的敏感性。3)“地球联系”：在这个主题中，讨论了地下，特别是上地幔与外生系统之间的地球化学交换过程。这些过程包括地球表面和俯冲带的相互作用以及洋壳的产生和蚀变。4)“运动中的地球”：该主题针对与社会直接相关的短期地球动力学过程，如地震带、山体滑坡和海啸。此外，这一主题还有助于海底碳固存的研究和海底观测站的安装。
