Looking Down on the Earth: How Satellites Have Revolutionized Our Understanding of Our Home Planet

scope

Earth is a complex, dynamic system we do not yet fully understand. The Earth system, like the human body, comprises diverse components that interact in complex ways. We need to understand the Earth's atmosphere, lithosphere, hydrosphere, cryosphere, and biosphere as a single connected system. Our planet is changing on all spatial and temporal scales. This presentation will highlight how satellite observations are revolutionizing our understanding of and its response to natural or human-induced changes, and to improve prediction of climate, weather, and natural hazards.

MICHAEL H. FREILICH, Director of the Earth Science Division, Science Mission Directorate at NASA Headquarters. Prior to NASA, he was a Professor and Associate Dean in the College of Oceanic and Atmospheric Sciences at Oregon State University. He received Ph.D. in Oceanography from Scripps Institution of Oceanography (Univ. of CA., San Diego) in 1982. Dr. Freilich's research focuses on the determination, validation, and geophysical analysis of ocean surface wind velocity measured by satellite-borne microwave radar and radiometer instruments. He has developed scatterometer and altimeter wind model functions, as well as innovative validation techniques for accurately quantifying the accuracy of spaceborne environmental measurements. Dr. Freilich has served on many NASA, National Research Council (NRC), and research community advisory and steering groups, including the WOCE Science Steering Committee, the NASA EOS Science Executive Committee, the NRC Ocean Studies Board, and several NASA data system review committees.

地形計測の研究史と地形学の学術出版

scope

地形の計測と、得られたデータに基づく地形の定量的な分析は、地球惑星科学の重要な手法です。本講演の前半では、紙の地形図を用いて手作業で地形を計測していた時代から、DEM(デジタル標高モデル)とGIS(地理情報システム)を活用し、解像度が高く複雑な計測を行う時代に至る研究史を紹介します。また、地形計測の学術的な意義と今後の展望を述べます。本公演の後半では、地形学の国際誌 Geomorphology(Elsevier)のチーフ・エディターを12年間担当してきた経験を踏まえて、学術出版に関する話題を述べます。特に院生やポスドクの方に向けた、国際誌向けの論文の執筆のコツや倫理に関する内容を含みます。

THE HAWAIIAN RIDGE: US-JAPANESE COOPERATION AND NEW PERSPECTIVES

scope

The Hawaiian Ridge is one of Earths most outstanding geologic features, spanning 3500 km in the north central Pacific basin. The Ridge is classified as a Large Igneous Province with its 70 major volcanoes, which produced 5.5 x 106 km3 of new oceanic crust during the last 50 million years. Along the Ridge there is remarkable variation in the magmatic flux (2-16 m3 s-1), and in volcano shape (conical to giant rift zones >100 km long) and size (<1 to 80 x 103 km3). Numerous giant landslides are found along the Ridge. Rapidly formed oceanic islands like Hawaii pose a serious natural hazard potential for people living in and around the Pacific Ocean. JAMSTEC expeditions to Hawaii (1999-2003) lead to many fundamental discoveries about the Hawaiian Islands. Garcia and colleagues have embarked on a new program of discovery to map and chemically analyze rock samples (including dating) from the poorly known section of the Ridge northwest of the Hawaiian Islands. Highlights of this work will be presented.
Michael Garcia

profile

Michael Garcia is a Professor of Geology at the University of Hawaii in Honolulu. He joined the University in 1976 as an assistant professor. His classes include igneous petrology, Hawaiian and California geology and how to write a scientific journal paper. Dr. Garcia’s research group focuses on the origin and evolution of Hawaiian volcanoes, including the active and extinct volcanoes from on land and at sea. During the 1999-2000 JAMSTEC expeditions to Hawaii, Dr. Garcia was the lead U.S. representative and dove on the 500th dive of the Shinkai 6500 submersible. Research by Dr. Garcia addresses the generation, differentiation and emplacement of basaltic magmas as well as giant Hawaiian landslides. His research on dike emplacement has taken him twice to the Dry Valleys of Antarctica and to volcanoes around the world (including Japan). His academic training is in geology (B.S., Humboldt State University, California, 1971, Ph.D., University of California at Los Angeles, 1976). In addition to his academic duties, Dr. Garcia is a part-time Technical Judge for the U.S. Nuclear Regulatory Commission.

The Impacts of Space Weather on Society and the Economy

scope

Modern society depends heavily on a variety of technologies that are vulnerable to the effects of intense geomagnetic storms and solar energetic particle (SEP) events. Strong currents flowing in the ionosphere can disrupt and damage Earth-based electric power grids and contribute to the accelerated corrosion of oil and gas pipelines. Magnetic storm-driven ionospheric disturbances interfere with high-frequency radio communications and navigation signals from Global Positioning System (GPS) satellites. Exposure of spacecraft to solar particles and radiation belt enhancements can cause temporary operational anomalies, damage critical electronics, degrade solar arrays, and blind optical systems such as imagers and star trackers. A complete picture of the socioeconomic impact of severe space weather must include both direct as well as collateral effects of space-weather-driven technology failures on dependent infrastructures and services.
