Geochemistry

The Geochemistry faculty study a wide range of processes and interactions, including products of large-scale Earth differentiation, such as the composition, evolution and age of the mantle and core, the formation and evolution of oceanic and continental crust, interactions between the geochemical environment (soil, water, air) and human health, fundamental questions involving the oceans and continental water systems, global geochemical cycles involving the atmosphere, oceans and Earth's interior, natural and engineered methods for carbon capture and storage, and using a wide range of geochemical archives to understand how and why the ocean and climate have changed at timescales ranging from seasons to millions of years. The faculty has developed strong collaborations with Columbia University engineers, biologists, public health researchers and American Museum of Natural History petrologists, planetary geologists and paleontologists.

My research interests involve the application of trace elements and isotopes, such as noble gases, radiogenic, cosmogenic, and extraterrestrial nuclides as well as oxygen, carbon and hydrogen isotopes, to problems at the interface between climate, biogeochemistry, and environmental studies., Most of my studies focus on marine systems, both modern and paleo. More recently, I have started working with ice cores as an archive of past climate conditions.

Fields of interest: 

geochronology, sedimentary geochemistry, paleoclimate, continental crust evolution

I consider my field to be Historical Geology. Using the record from sediments and sedimentary rocks, I seek to document aspects of Earth's history. Understanding the provenance and processes recorded in the geochemistry of sediments and sedimentary rocks lies at the heart of my research interests. I have strong interest in tectonics and continental crust evolution questions on the longer time scale. I have an active program of applying radiogenic isotopes for tracing the sources of sediments with the goal of understanding Quaternary climate changes and associated changes in winds, currents and glaciers. Provenance studies of ice rafted detritus are key to working out the dynamic relationships among paleo-climate and paleo-ocean circulation and their interactions with the large ice sheets that covered the northern continents during the ice ages. Geochronology is essential to my research and I am actively participating in projects to improve our ability to obtain reliable age estimates on events in Earth's history.

Fields of interest: 

CO2 cycling through oceans and atmosphere; industrial CO2 accumulation.

My main research is aimed at understanding the fate of industrial CO2 released in the air. Since the beginning of the Industrial Revolution in the 1800s, the atmospheric concentration of CO2 has increased by nearly 30% in the 1990s and it is anticipated that it will double the pre industrial level by the middle of the 21st century. This could cause a global warming and changes in climate, which may extensively impact upon the global community. The observed increase in this "greenhouse" gas in the air is half of that which is expected from the full released amount. Thus, this suggests that about one-half the industrial CO2 released is being absorbed by the global oceans and land plants. However, the relative importance of these two CO2 sinks is not understood. Furthermore, the uptake capacity of these CO2 sinks conceivably could be reduced as more CO2 accumulates in the air.

My research group measures CO2 and related quantities in the world oceans, from the Arctic to Antarctic regions, to learn how fast atmospheric CO2 is transferred into the different areas of the oceans. Seasonal and annual changes are being documented. These measurements provide basic information on how CO2 is cycled through the oceans and atmosphere and how these cycles are affected in response to industrial CO2 being accumulated at ever-increasing rates. I hope that my study will lead to a better understanding and hence to a reliable prediction of the oceans capacity to absorb industrial CO2.

Isotope Hydrology, Water Resources, Paleoclimate.

When I was about eight-years-old, I did not speak to my parents for a whole day because they threw a banana peel out of our car, which I found was unacceptable from an environmental point of view. I knew early on that I wanted to dedicate my career to environmental issues and studied Physics, because there was no such thing as Environmental Science back then. My PhD thesis research topic at the University of Heidelberg focussed on novel tracer techniques to study the dynamics of ground water flow, and the use of ground water as an archive of paleoclimate. I have been interested in water issues ever since and can still hardly resist to take a plunge into a thermal spring I encounter or take a sip from a well that might tap an interesting aquifer. I believe that water will play an increasingly important role in our attempts to achieve a sustainable global development. I am also trying hard to be a decent teacher and undergraduate and graduate student adviser, because I think that is where faculty members have the most influence on the future of our planet.

Fields of interest: 

Aqueous Geochemistry, Physical Oceanography, Climate, Contaminant Transport.

My research focuses on the application of noble gases and other isotopes to natural systems with emphasis on the oceans and groundwater. My research is directed to understanding the natural state of these water bodies, the human perturbation of the natural state, and the possibility to design engineering solutions to the problems caused by human impact. The problems we are working on range from basic studies of circulation patterns of water in the ocean and groundwater flow systems to the variability of the oceanic circulation under natural and anthropogenically forced conditions or the transport and transformation of contaminants. Other projects include paleoclimate and paleocirculation studies.

For most of our studies, we use trace substances of natural or anthropogenic origin (isotopes or chemical compounds). In some cases we follow the penetration of such substances into the water bodies of interests in a fashion that is similar to dye experiments, but on a much larger scale. In other cases, we use combinations of isotopes as ?radioactive clocks? (e.g., tritium, the radioactive isotope of hydrogen, and its decay product, the noble gas isotope 3He). In some cases, we deliberately inject small amounts of inert trace gases into specific water bodies (e.g., the Hudson River) and study their spreading and mixing. Such experiments provide the closest analogues to the spreading of contaminants in the environment.

In many cases, we combine our experimental work with modeling studies to understand the underlying physics of the circulation or to explore predictability. Modeling studies also provide insight into management options for certain water bodies.

Role of the oceans in climate change using isotopes.

As I sometimes tell my students My research is directed toward the role of the oceans in climate change. Over the last several hundred thousand years, the folks in the back room who designed our planet were pretty clever. We have clear evidence that different parts of the earth's climate system are linked in very subtle yet dramatic ways.

The climate system has jumped from one mode of operation to another in the past. We are trying to understand how the earth's climate system is engineered climate change has come mainly in discrete jumps that appear to be related to changes in the mode of thermohaline circulation.

We place strong emphasis on using isotopes as a means to understand physical mixing and chemical cycling in the ocean ,so we can understand what it takes to trigger mode switches. Until we do and the climate history as recorded in marine sediments.  ,we cannot make good predictions about future climate change. and the climate history as recorded in marine sediments.
