Environmental Sciences and Energy Research

 

Brian Berkowitz, Head
The Sam Zuckerberg Professorial Chair

Research in the department includes both experimental/field and theoretical studies focused on understanding the complex inter-relationships among the major Earth systems, and on the human need for non-polluting energy sources.

Scientists in the department have expertise in a range of Earth-Science disciplines, including climate dynamics, oceanic circulation, hydrology, paleoceanography and the study of past climatic patterns, plant-environment interaction, atmospheric chemistry and earth system dynamics. These disciplines, and topics studied in each one of them, are ultimately integrated as a means to understand and predict local, regional and global changes.

Our main objective for the future is to develop scientific activities that explore the critical interfaces coupling the Earth systems. These include the biosphere-atmosphere, ocean-atmosphere, ocean-sediment, and land surface-groundwater interfaces. We also aim to offer solar energy sources as alternative to those which are adversely affecting our environment.

Research topics in the Department of Environmental Sciences and Energy Research include:

Atmospheric chemistry: Analytical chemistry of the atmosphere; Aerosol physics and chemistry including surface and heterogeneous chemistry; Aerosol optical properties; vegetation-climate interactions; Aerosol-climate interactions, Nano-particle chemistry in the atmosphere(Principal investigator: Yinon Rudich)

Clouds and cloud-aerosol interactions: Using remote sensing to study the radiation transfer in the atmosphere, cloud microphysics, inversion of the physical properties of the clouds and aerosols. Remote sensing and patterns and texture in clouds are also used to estimate manmade impacts on the radiation and the thermodynamic balance of the atmosphere, as well as on the water cycle. (Principal investigator: Ilan Koren)

Hydrology: Integration of laboratory and field studies with theoretical models to understand flow of water, and transport of conservative and reactive chemicals, from the ground surface, through the unsaturated zone, and within saturated geological formations. Transport in porous media. Development of chemical methods for remediation of contaminated water. (Principal investigator: Brian Berkowitz)

Biogeochemistry: Plant-atmosphere interactions; Environmental influence on the exchange of trace gases and energy between land ecosystem and the atmosphere; Climatic influence on the natural abundance of carbon; oxygen and hydrogen isotopes in CO2, H2O and organic materials; Scaling biological processes from cellular to global scales. Tracing photosynthetic CO2 fluxes with Carbonyl Sulfide (COS).(Principal investigator: Dan Yakir)

Physical Oceanography and climate dynamics: Interactions between ocean biota and climate; Climate dynamics and paleoclimate; Dynamics of the Gulf of Eilat; Radio-wave oceanography. (Principal investigator: Hezi Gildor)

Paleoceanography and climate change: Global climate change reconstructions from stable isotope records in marine and continental sediments; Southern Ocean paleoceanography. Oxygen isotopes in biogenic silica; Stable isotopes in diatom records; Carbon and oxygen stable isotopes in corals. (Principal investigator: Aldo Shemesh)

Energy Research: Focusing mainly on finding methods of utilization of concentrated solar radiation for efficient, cost-competitive solutions affecting

This includes the development of new solar thermal systems; solar derived 'clean' fuels; concentrated photovoltaic systems; high temperature water splitting and carbon dioxide dissociation; high temperature water splitting; high temperature catalytic processes.
