Dr. Eicken's research includes studies of the growth, evolution and properties of sea ice. Hajo is particularly interested in determining how microscopic and macroscopic properties affect larger-scale sea-ice processes and its role in the climate system. He also investigates different uses of sea ice by indigenous communities, the private sector and the public at large and aims to provide data and information that can help decision-makers adapt to a changing Arctic.
Recent and ongoing work and research interests include:
- the evolution of pore and grain microstructure as a function of growth conditions and thermal forcing, using thin-section imaging and magnetic resonance imaging
- studies of brine and meltwater transport within Arctic sea ice through the use of active and passive tracer techniques;
- laboratory and field measurements of sea-ice permeability and its linkage to pore structure and large-scale ablation processes;
- small- and large-scale processes from the isotopic composition of sea ice;
- field and remote-sensing studies of growth, development and dynamics of sea ice
- the ecological significance of sea ice and its role as a habitat;
- resilience and adaptation in marine coastal environments in a changing Arctic (see also http://www.uaf.edu/rap)
