The Great Lakes Workshop Series on Remote Sensing of Water Quality brought together international researchers on the remote sensing of inland waters and the end users who put remote sensing products to work monitoring and managing the Great Lakes.
The 2014 series consisted of two workshops, each lasting two days, that included plenary presentations, breakout groups, and networking events. Participants learned about remote-sensing resources and best practices from leaders in the field, connected with other attendees for potential collaborations, and contributed to the development of a working community of practice for Great Lakes remote sensing. Stakeholders gained in-depth insight into how to apply available remote sensing products to their organization’s current challenges and had the opportunity to provide direct input into future priorities for data product development. It is hoped that the series can be continued with annual update meetings in future years.
- Review and update remote sensing data requirements for the Great Lakes
- Compare the approaches and performance of different algorithms/remote sensing models and currently available sensors/platforms for the derivation of water quality parameters
- Review the status, strengths, and deficiencies of approaches currently in use
- Identify and start to prioritize data and technology gaps
- Create a “wish list” of applications for Great Lakes remote sensing, including consideration of resolution, spectral bands/wavelengths, signal-to-noise ratio, and others
- Begin to reach agreement on current research priorities
All plenary presentations loaded onto an interactive website. Breakout group reports at the end of the meeting. Presentation summary of the breakout groups that identifies data gaps. User forums and contact info available on website.

Great Lakes Remote Sensing Community of Practice
Remote sensing of the Great Lakes has been a focus of three previous meetings: a conference held at NASA Glenn Research Center in April 2010 with the objective of defining NASA’s role in advancing environmental science in the Great Lakes, a NOAA GLERL workshop held May 8-9 2012 in Ann Arbor, Michigan, and the Workshop for Remote Sensing of Coastal and Inland Waters, held June 20-22 2012 in Madison, Wisconsin. These meetings were a good start where stakeholders networked, began the process of defining the requirements and providers of derived remote sensing products, and summarized present and anticipated capabilities. However, the needs identified in these meetings, e.g., collecting existing optical and in situ data in a single location to facilitate analysis, developing a standard set of recommended observations, and creating an entity to serve as the clearinghouse for data on inland and coastal waters for all stakeholders, require further collaboration at the level of the research community in order to bring them about. The upcoming workshops will serve to summarize and carry forward the work accomplished at these previous meetings.
NOAA GLERG 2012 Workshop Summary, from Colton 2013
“Current and future remote sensors for the Great Lakes were among the discussion topics at the NOAA Great Lakes Environmental Research Lab (GLERL) workshop held May 8-9, 2012, during which approximately 30 professionals from the Great Lakes region met in Ann Arbor, MI. The diverse group of attendees represented federal (NASA, NOAA, USFWS, and USGS) and state agencies (from Michigan, Minnesota, Pennsylvania, and Wisconsin), academia (MTU-MTRI, UM-TC, UM, MSU, UW), and the non-profit organization GLOS. Meeting topics addressed sensors and platforms, currently developed products, data distribution and management, as well as user and stakeholder needs. The meeting objective was fundamentally focused on renewing and creating professional connections among the individuals actively working in regional remote sensing research, proposing a research and applications working group, and collecting ideas for a conceptual work plan design that would form the basis for a regional remote sensing community of practice.“
Summary of the 2012 Workshop for Remote Sensing of Coastal and Inland Waters
For a recent review of the state of the science of Great Lakes remote sensing, see the Journal of Great Lakes Research’s 2013 Special Issue on Remote Sensing.
Through a series of interactive workshops and use of an interactive web site, establish a network of regional, national and international stakeholders to better utilize remote sensing technologies to address Great lakes issues.
The stakeholders include not only aquatic remote sensing investigators, but managers, regulators, researchers, educators, and the general public and represent federal, state, local agencies, universities and colleges, tribes, and not-for-profit research centers.
The state of the science of remote sensing of inland waters, particularly the Great Lakes, has progressed significantly over the past decade, in step with investments by NASA in next-generation satellite infrastructure, the improvement of freshwater-specific optical algorithms, developments in aquatic applications of radar and lidar data, and the availability of increasingly capable unmanned aerial systems (UASs) and autonomous underwater vehicles (AUVs), among other advances. However, despite efforts by the Great Lakes Observing System (GLOS), the Great Lakes Commission and other entities to coordinate research and facilitate data sharing, the evolution of a regional remote sensing community of practice in the Great Lakes is still in its early stages. In an effort to provide the basis for continuing advances in the state of science and technology of remote sensing of inland water quality, Great Lakes stakeholders, policymakers, and researchers involved in remote sensing science and monitoring are invited to a series of two workshops. These workshops, and their accompanying interactive website and information sharing system, will provide a platform for collaboration between stakeholders and researchers and help to establish a community consensus on scientific and technical gaps and research priorities in this area. Proceedings from the workshops will include a summary white paper and a community website with networking capabilities and access to meeting documents.
