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

这一奖项是为了支持一次国际研讨会，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，以及这些岛屿如何为生物进化提供框架。研讨会还将讨论夏威夷、留尼汪岛和冰岛等其他海洋岛屿省份的起源和演化，以加深我们对热点火山活动的基本理解，包括深部地幔过程、地球化学库、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勘探在很大程度上是按照学科路线进行的，缺乏对大量和不断增长的现有信息进行令人满意的综合。由于若干因素，加拉帕戈斯群岛为这种综合提供了理想的环境：在加拉帕戈斯地台广泛分布的岛屿上暴露的火山样式和产物多种多样，与加拉帕戈斯热点有关的火山喷发历史漫长且保存完好，羽脊相互作用的明显地球化学和地球物理特征，进行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的影响的独特条件。对加拉帕戈斯地区正在进行和计划中的重要研究推动了一项旨在整合、综合和战略设计未来勘探的投资。预期这次专题讨论会将成为整理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的论坛，这些文章将在AGU地球物理专著中发表。此外，还将编写一份报告，以确定未来勘探的战略目标，包括数据获取和解释。主要建议将侧重于加拉帕戈斯以及其他海洋岛屿遗址的未来工作。预计国际社会对海洋岛屿省份的了解可能会从这次研讨会中诞生。这次研讨会的中心目标是整合不同学科的知识，这些知识有助于我们了解海洋岛屿省份，包括地质学、地球化学、地球物理学和进化生物学。研讨会将是国际性的，将由加拉帕戈斯群岛的查尔斯·达尔文研究站主办。与会者中将有一些厄瓜多尔科学家和官员，他们参与未来对加拉帕戈斯群岛的研究至关重要。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。研讨会还将提供重要的推广机会，将达尔文站、厄瓜多尔机构、各种保护组织以及国际科学界的努力结合起来。这笔赠款将支持参与者的旅费和住宿费，以实现知识综合和社区广泛参与这两个目标。

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.
