Earth and Space Sciences Informatics (ESSI) is concerned with evolving issues of data management and analysis, technologies and methodologies, large-scale computational experimentation and modelling, and hardware and software infrastructure needs. Together, these elements provide us with the capability to change data into knowledge that can be applied to advance our understanding of the Earth and Space Sciences. This session is for presentations on all aspects of Earth and Space Science Informatics, especially those topics not represented by other ESSI sessions.
