An airborne geophysical program over West Antarctica was designed to study the linkage between the West Antarctic Rift System and the dynamic evolution of the overlying West Antarctic Ice Sheet. The integrated data acquisition system mounted on a DeHavilland Twin Otter consists of an airborne gravity system, a towed aeromagnetic system, an ice penetrating radar, and a laser altimeter. The aerogeophysical data set covers a 300,000 km2 region in West Antarctica. The survey area is covered by a grid of orthogonal flight lines spaced 5.3 km apart in both directions consisting of 150,000 line kilometers. Flight elevation varied from 1600 m to 2500 m (check here for details).

The NAO is the dominant mode of winter climate variability in the North Atlantic region ranging from central North America to Europe and much into Northern Asia. The NAO is a large scale seesaw in atmospheric mass between the subtropical high and the polar low. The corresponding index varies from year to year, but also exhibits a tendency to remain in one phase for intervals lasting several years. The climate of the Atlantic sector and surrounding continents exhibits considerable variability on a wide range of time scales. Improved understanding of this variability is essential to assess the likely range of future climate fluctuations and the extent to which these fluctuations are predictable, and to assess the potential impact of climate change due to anthropogenic forcing.

The mission of theColumbia Center for Hazards and Risk Research at Lamont-Doherty Earth Observatory is to advance the predictive science of natural and environmental hazards and the integration of science with hazard risk assessment and risk management. It is within the context of a compelling social need for reduction ofcatastrophic events from natural and environmental hazards that a group of Columbia's physical and social scientists are proposing a new program in disaster studies. Drawing from research capacity in the earth and environmental sciences, engineering, social sciences and public policy, the Center for Hazards and Risk Research will have a twofold focus: the assessment of predictive science capability and the integration of science with hazard risk assessment and management. Operationally this will require advances in the geospatial-demographic modeling of physical processes and their potential societal impacts. It will also require a renewed focus on the translation of scientific concepts of probability and uncertainty into a language and set of rules useful to decision-makers.

Dramatic changes in early human evolution occurred in East and South Africa during the last ca. 5 Ma. These evolutionary changes include the gradual emergence of larger and bigger brained species, including the first appearance of our genus, Homo and the development of stone tools near ca. 2.6 Ma. Analysis of the fossil record from East and South Africa suggests that African fauna evolved in series of "pulses", centered near ca. 2.8 Ma, 1.8 Ma, and 1.0 Ma. Paleoclimate evidence from Africa and its adjacent oceans documents significant shifts in African climate towards progressively drier conditions. This "drying" of subtropical Africa occurred as a series of steps, also centered near ca. 2.8 Ma, 1.8 Ma, and 1.0 Ma. These fossil and paleoclimate results lend new support to environmental hypotheses of African faunal evolution, which state that critical junctures in African faunal evolution were mediated by ecological shifts forced by changes in African paleoclimate. As a result of ongoing efforts at this institution and at a number of research groups around the world, we are making progress on the question of how the evolution of hominids and other African vertebrates may have been shaped by past changes in African climate. This web site presents some of the current research topics being addressed at Lamont-Doherty Earth Observatory.
