Title: Assessing the volume and hypsometric changes of the glaciers
in the Tropical Peruvian Andes: Some case studies over Cordillera Blanca
Tropical glaciers are very sensitive to changes in climate due to the low latitude radiation regime and steep vertical mass balance gradients. These mountain glaciers have rapidly retreated over the 20th century, raising concerns about downstream regional water supplies under continued global climate change. Monitoring tropical glaciers using remotely sensed data has drawn a great attention in earth science communities for decades and time-lapse analysis of sensory data has
provided important variability information of tropical glacier recession. The motivation of this study is to refine a surface area to volume relationship for tropical glaciers to enable extrapolation of more detailed inventory of glacier volume and water resources. This study
focuses on the glaciers in the Cordillera Blanca in Peru, within the world’s largest concentration of tropical glaciers, to assess the volume and topographic changes over the late 20th century. A combination of LiDAR (Light Detection and Range) data achieved in 2008, DEMs (Digital Elevation Models) from vertical aerial photographs taken in 1962 by stereo-photogrammetry, and multispectral ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer)
imagery taken during 2001 – 2008 with geospatial techniques are used for this research. These airborne and Spaceborne imagery can reveal both current glacial surface topography and glacial
profiles 46 years back, enabling calculation of the total volume loss trend over the last 46 years.
The resulting improved understanding of how tropical glacier mass changes in response to climate dynamics is critical for global climate modeling, which can reliably predict future glacier changes only after accurately simulating the past.

Abstract
Over the past several years, the Ocean Engineering Laboratory (OEL) of the University of Michigan has been involved in the design, fabrication and deployment of a wide variety of Great Lakes and coastal ocean environmental monitoring platforms. These platforms are all either, semi- or fully-autonomous in the execution of their respective missions and capable of producing real-time data. The development of these platforms offers a glimpse into the possible future of advanced aquatic sensing and long term, open water, measurement persistence. Examples of the utilization of these and other environmental sensing platforms, many developed jointly with MTU, will be provided. Applications to a variety of Great lakes and coastal ocean environments will be discussed including searching for evidence of Paleo-Indian occupation of what is now the submerged Alpena-Amberley, central ridge of Lake Huron.
