The Geological Evolution of the Galapagos Archipelago and Other Ocean Island Provinces: A Proposal for an International, Multidisciplinary, Field-Based Symposium

该奖项是为了支持一个国际研讨会，以更好地整合我们对加拉帕戈斯群岛的地质，地球化学和地球物理演化的知识，以及岛屿如何为生物进化提供框架。研讨会还将讨论其他海洋岛屿省份的起源和演化，如夏威夷，留尼汪岛和冰岛，以进一步加深我们对热点火山作用的基本理解，包括深地幔过程，地球化学储层，岩石圈变形和岩浆演化。 对加拉帕戈斯群岛和其他海洋岛屿省份的探索主要是沿着学科路线进行的，对现有的大量和不断增长的信息缺乏令人满意的综合。加拉帕戈斯群岛为这种综合提供了理想的环境，原因有以下几个：广泛分布在加拉帕戈斯地台的岛屿上暴露出的各种各样的火山样式和产物，与加拉帕戈斯热点有关的长期和保存完好的火山活动历史，地幔柱-山脊相互作用的独特地球化学和地球物理特征，地震成像研究的优越条件，以及研究地质环境对进化生物学影响的独特条件。加拉帕戈斯地区正在进行和计划进行的重要研究激励了针对未来探索的整合，综合和战略设计的投资。 预计这次专题讨论会将成为一个论坛，整理关于加拉帕戈斯和其他海洋岛屿省份地质和地球物理知识现状的文章，这些文章将在AGU地球物理专题论文中发表。此外，还将编写一份报告，确定今后勘探的战略目标，包括数据采集和解释。主要建议将侧重于加拉帕戈斯群岛以及其他海洋岛屿遗址的未来工作。本次研讨会的中心目标是整合地质学、地球化学、地球物理学和进化生物学等多学科知识，以帮助我们更好地理解海洋岛屿省。该专题讨论会将具有国际性质，将由加拉帕戈斯群岛的查尔斯达尔文研究站主办。与会者中将包括一些厄瓜多尔科学家和官员，他们的参与对今后的加拉帕戈斯研究至关重要。我们将从广泛的相关学科招募与会者，重点是早期职业科学家，他们将受到加拉帕戈斯群岛科学奇迹的启发。作为专题讨论会的一个组成部分，所有与会者将有机会参加有导游的实地考察，包括几个岛屿上的活火山和死火山。专题讨论会还将提供重要的机会，使达尔文站、厄瓜多尔各机构和各种保护组织以及国际科学界的努力结合起来，进行宣传。 这笔赠款将用于支持参与者的差旅和住宿费用，以实现知识综合和广泛社区参与的双重目标。

This award is to support an international symposium to better integrate our knowledge of the geological, geochemical, and geophysical evolution of the Galápagos Archipelago, and how the islands have provided the framework for biological evolution. The symposium will also address the origin and evolution of other ocean island provinces such as Hawaii, Reunion, and Iceland in order to further our fundamental understanding of hotspot volcanism, including deep mantle processes, geochemical reservoirs, lithospheric deformation, and magma evolution. Exploration of the Galápagos and other ocean island provinces has proceeded largely along disciplinary lines, and satisfactory syntheses of the vast and growing body of information available are lacking. The Galápagos Archipelago offers an ideal setting for such a synthesis, owing to a number of factors: The great variety of volcanic styles and products exposed on islands that are distributed broadly across the Galápagos platform, a prolonged and well-preserved history of volcanism associated with the Galápagos hotspot, distinct geochemical and geophysical signatures of plume-ridge interactions, excellent conditions for seismic imaging studies, as well as the unique conditions for studying the influence of geological circumstances upon evolutionary biology. Important ongoing and planned studies of the Galápagos region motivate an investment targeted at integration, synthesis, and strategic design of future explorations. It is expected that this symposium will serve as a forum for the collating articles regarding the current state of geological and geophysical knowledge of the Galápagos and other ocean island provinces to be published in a special AGU Geophysical Monograph. In addition, a report will be written to identify strategic objectives for future exploration, including both data acquisition and interpretation. Primary recommendations will focus on future work in the Galápagos, as well as that in other ocean island sites. It is anticipated that an international community effort directed toward the understanding of ocean island provinces may be born out of the symposium.The central goal of this symposium is to integrate knowledge across various disciplines that contribute to our understanding of ocean island provinces, including geology, geochemistry, geophysics, and evolutionary biology. The symposium will be international in character, and will be hosted by the Charles Darwin Research Station in the Galápagos Islands. Among the participants will be a number of Ecuadorian scientists and officials, whose participation in future studies of the Galápagos is crucial. We will recruit attendees from a broad range of relevant disciplines, with emphasis on early career scientists who will be inspired by the scientific wonders of the Galápagos Archipelago. As an integral part of the symposium, all participants will have the opportunity to attend guided field trips including both active and extinct volcanoes on several islands. The symposium will also provide important opportunities for outreach combining the efforts of the Darwin Station, Ecuadorian agencies, and various conservation organizations, as well as the international scientific community. This grant will support participant travel and accommodation expenses in order to achieve the twin goals of knowledge synthesis and broad community involvement.
