Remote sensing of trace gases from ground and space based instruments
Lecturer: Abstract:
Remote sensing of the atmosphere is an invaluable tool to understand the earth’s atmosphere. The talk gives an introduction to state of the remote sensing in the ultraviolet to the short wave infrared spectral region. Many key players of atmospheric chemistry can be measured, which includes e.g. O3, NO2, SO2, HONO, HCHO, Halogen compounds, Glyoxal, CO, CO2 and CH4. Applications are discussed at the example of measurements of volcanic plumes, Arctic bromine explosion and Ozone depletion events, as well as observation of greenhouse gases from space.

"Certezas e incertidumbres sobre el impacto de los extremos térmicos sobre la salud y de otros factores ambientales asociados a las altas temperaturas"
Dr. Julio Díaz, Instituto de Salud Carlos III
Date: 30th of April, 2014
Time: 10:00
Venue: BC3 offices
Language: Spanish
Es evidente que desde que se produjo la ola de calor del año 2003 en
Europa se ha producido un gran avance en el conocimiento de cómo los
extremos térmicos afectan a la salud de la población, pero aún sigue
habiendo discrepancias en el seno científico que afectan a cuestiones
tan básicas como la propia definición de ola de calor. Este mayor
conocimiento ha traído en paralelo el planteamiento de cuestiones de
gran importancia para el establecimiento de los Planes de Prevención
como medida de adaptación ante estas temperaturas extremas: ¿Las
temperaturas a las que se articulan los Planes de Prevención se
mantienen constantes en el tiempo? ¿Cambian los impactos en salud como
consecuencia de las variaciones sociodemográficas? Por otro lado, y para
el caso del calor extremo, se está avanzando en el conocimiento de los
impactos que otros factores ambientales, concomitantes con las altas
temperaturas, pueden tener sobre la salud de la población como es el
caso de las intrusiones de polvo sahariano o la advección de material
particulado como consecuencia de la combustión de biomasa en los
incendios forestales. Ante el cambio climático presente urge dar
respuestas a estos interrogantes que se plantean y que van a ser claves a
la hora de articular las medidas preventivas necesarias para minimizar
los efectos que estos factores ambientales tienen sobre la salud de la
población.

The molecular structure of ice grain boundaries and its role in the dynamics of polar ice sheets
Lecturer: Abstract: The polar ice sheets that cover Greenland and Antarctica play a crucial role in the global climate system. Discharge of ice into the ocean by massive creep flow affects global sea level and the ocean/atmospheric circulation patterns that govern the climate of Earth. During the past two decades, several deep ice drilling projects have been conducted in Greenland and Antarctica, in order to investigate the physical and chemical properties of polar ice. From these investigations it transpires that molecular processes occurring within polycrystalline ice and at its grain boundaries play a decisive role in the dynamics of polar ice sheets, because they may determine the dominant deformation mechanisms of ice in situ. The fact that the creep of ice sheets occurs at extreme conditions (stresses lower than 100 kPa, temperatures down to −50ºC, strain rates about 10−12 s−1, and total shear strains exceeding 1000%) makes it very difficult to reproduce and clarify the mechanisms of polar ice deformation in laboratory. For these reasons, we decided to investigate the mechanics of ice sheets by understanding the microscopic behavior of water molecules within ice grains and at their boundaries. In this seminar I will talk about the physical properties of the grain boundaries of polar ice and their role in the dynamics of polar ice sheets. To this aim I present our recent experimental results of ultra-slow ice-creep tests by using a modified phase modulation homodyne interferometer and the results of creep tests with very fine polycrystalline ice obtained by a new method that exploits ice polymorphism.
Speaker’s Short Vita (By S.H. Faria, BC3): Prof. Nobuhiko Azuma is Professor of Mechanical Engineering and Executive Director/Vice-President of the Nagaoka University of Technology, Nagaoka, Japan. He earned his Dr.Eng. degree in 1986 from the Department of Applied Physics, Hokkaido University, Sapporo, Japan, under the supervision of Prof. Akira Higashi. After that he worked as Research Assistant at the Department of Geological Sciences, State University of New York at Buffalo, USA, where he started his career as an ice core physicist in the group of Dr. Chester C. Langway, Jr., a pioneer of ice core research. Then, he returned to the Department of Applied Physics, Hokkaido University, Japan, to participate in the Japanese project of deep ice drilling at Dome Fuji, Antarctica. In the period 1988–1994 he visited Antarctica and Greenland several times performing tests and experiments for the deep drilling project and in 1994 he effectively started the deep drilling at Dome Fuji over the winter (deep drilling at Dome Fuji successfully finished in 2007, after retrieval of two deep ice cores amounting to more than 5 km of ice). In 1990 he was appointed Associate Professor of the Department of Mechanical Engineering, Nagaoka University of Technology, and became full professor in 2004. His research interests include ice core analyses, ice physics and ice drilling technology. He is regarded today as one of the leading names of polar ice physics worldwide.
