Jakob Lindaas Named 2020-2021 AGI Fisher Congressional Fellow

ALEXANDRIA, Va. - The American Geosciences Institute (AGI) congratulates Jakob Lindaas on his selection as the 2020-2021 William L. Fisher Congressional Geoscience Fellow. The Fisher Fellowship offers geoscientists the unique opportunity to spend a year in Washington, D.C., working as a staff member in the office of a member of Congress or with a congressional committee.

Mapping Displacement and Subsidence with Time-series Radar

Wednesday, April 15, 2020


Two related developments have moved the use of radar imagery into the operational realm. The supply of available data has increased greatly, especially with the freely-available Sentinel-1 satellites. And the analysis algorithms are now tested and established, producing reliable and standardized Information Products. One application in particular has benefited greatly from these synergistic developments; centimeter-scale measurement of surface motion on a regional scale. The ability to produce time-series displacement maps with a high point density has revolutionized the monitoring, and mitigation, of subsidence due to subsurface extraction of resources such as water or hydrocarbons.

2019-2020 AGI Fisher Fellow Raleigh Martin

Raleigh Martin is an Earth-surface process geoscientist interested in enabling open knowledge, data, and policy in the geosciences. Prior to serving as the 2019-20 William L. Fisher Congressional Geoscience Fellow, Raleigh is completing an American Association for the Advancement of Science (AAAS) Science & Technology Policy Fellowship in the Directorate for Geosciences at the U.S. National Science Foundation (NSF). At NSF, Raleigh is helping to allocate infrastructure investments and to refine public access policies to advance geoscience research discovery through improved data access and reuse. Prior to NSF, Raleigh was a postdoctoral researcher at the University of California, Los Angeles (UCLA), where he studied wind-driven sediment transport processes shaping coastal and desert sand dunes and generating atmospheric dust. Raleigh earned his B.S.E. in Geological Engineering from Princeton University and his Ph.D. in Geology at the University of Pennsylvania, where his doctoral research focused on understanding the statistical variability of sediment transport and geomorphology in rivers.


Improving Earthquake Resiliency Through the Use of Post-Earthquake Clearinghouses

Thursday, November 14, 2019


Since 2000, there have been 51 significant earthquakes that have caused over $3.4 billion dollars in damages and 31 deaths in the United States.1 While large earthquakes pose a substantial threat along the West Coast and in Alaska, they also can affect the Central and Eastern United States, as they did during the 1811 and 1812 New Madrid earthquakes and 1886 Charleston, SC earthquake. Earthquakes can have wide ranging impacts, such as the 5.8 magnitude earthquake in Mineral, VA that happened in 2011 and was felt across multiple states along the East Coast, causing $200-$300 million in damages and this year’s 7.1 magnitude earthquake near Ridgecrest, CA that was felt in Nevada and Arizona, and cased $100 million in damages.1,2,3 A single event can be devastating: for example, the 1994 Northridge, CA, 6.7 magnitude earthquake caused at least $40 billion in direct damage and killed around sixty people.3

As population continues to expand into risk-prone areas, improved risk management practices are increasingly necessary to improve emergency preparedness and response by providing information on earthquake processes, assessing the adequacy of built infrastructure and building codes, and providing insight on how to improve future recovery and urban development efforts. Post-earthquake technical clearinghouses are a successful strategy for tracking the collection of information about ground failures, structural damage, and other impacts from major earthquakes, reducing duplication of effort in data collection, and disseminating information about events to emergency response managers. In this webinar, our speakers discuss earthquake risk in the U.S., the importance of coordinated post-earthquake response, and the effectiveness of post-earthquake technical clearinghouses in improving earthquake resiliency.

Geoscience Policy Internships and Fellowships: Pathways to Science Policy Careers

Saturday, December 1, 2018

Student and early-career geoscientists commonly seek professions with high societal impact, but pathways to alternative geoscience careers can be difficult to navigate, particularly in science policy and outreach. Many geoscience policy leaders enter the profession through the gateway of policy internships and fellowships. These opportunities crafted for those interested but inexperienced in science policy provide training in government processes, tangible experience in policy analysis, and integration into robust networks of professionals.

Bridging the Gap: Tailor-made Information Products for Decision Makers

Thursday, December 1, 2016

The American Geosciences Institute (AGI) is launching a new information platform designed to link decision makers with information generated by geoscientific research. Decision makers, especially those at the state and local level, frequently need scientific information but do not always have easy access to it, while scientists create new knowledge but often lack opportunities to communicate this knowledge more broadly to the people who need it the most. Major differences in communication styles and language can also hinder the use of scientific information by decision makers.

Navigating the boundary of science for decision making at the state and local level

Tuesday, December 1, 2015

Scientific information should play a vital role in many decision making processes, yet issues incorporating geoscience information often arise due to inherent differences between how scientists and decision makers operate. Decision makers and scientists have different priorities, produce work at different rates, and often lack an understanding of each others institutional constraints.
