Summary

Abstract: Earth sciences describe the Earth as a chemical, physical and biological system. This dynamic system accreted 4.6 billion years ago from the solar nebula and it evolved into a set of distinct chemical and physical reservoirs. These reservoirs include the Earth's core, mantle, crust, ocean and atmosphere and they continue to evolve through the continuous exchange of mass and heat. These processes result in major natural hazards to mankind (floods,draught, meteor impacts, volcanic eruptions and earthquakes), but they also created a habitable planet that provides an environment and resources that are favorable for the development and the maintenance of (human) life. The mandate of Earth sciences is to study the Earth, its chemical, physical and biological reservoirs and the processes that control the make-up and interaction between these reservoirs. It is becoming increasingly clear that chemical, physical and biological Earth processes interact in rather complex ways and require true integration of these disciplines. The mission of the PACER center is to help integration of the Earth sciences through supporting scientific communication and the development of global physical and chemical reference models.
