Becker ResearchAt the Environmental Remote Sensing Lab, we undertake research which incorporates an interdisciplinary research approach (remote sensing, geochemistry, hydrologic modeling, and field techniques) to investigate a wide range of geological and environmental problems including the assessment of responses of natural systems to climatic and human activities.

Examples of these include: Identifying and mapping potential harmful algal blooms from satellite images, and examining impacts of land use change on blooms and other systems in the Laurentian Great Lakes. In addition we study the impact on the Nubian aquifer in Northeastern Africa and Nile watershed of the construction of the Aswan High Dam, from changing recharge in the system to changing subsidence in the Nile Delta, to investigating the effects climate change has had on this system.

To do this we utilize a variety remote sensing and GIS techniques to investigate water resources and the impacts that human use may have on them.
