Who and what are we ???
http://greatlakes.mtu.edu/
The result of a 10 Year Plan…..• University Strategic Planning…• A New Waterfront Facility Dedicated to the Great
Lakes• Designed by Faculty…• Six New Strategic Faculty Hires…• Enable Collaborations across the Great Lakes Basin
and the World

Unique Approach:
The GLRC is a unique structure that brings a rich diversity of expertise from on campus and off, into a productive, multi‐use state of the art facility dedicated to addressing Great Lakes issues.• Shared cutting‐edge equipment.
• Focused on large scale, multi‐year, interdisciplinary funding.– Directed at Grand National challenges.
• The Great Lakes Center is designed to attract a dynamic mixture of student, faculty, researchers and business partners to work in collaboration on these challenging problems.
Major Areas of Focus
• Aquatic Ecology and Ecosystem Dynamics• Aquatic Ecology and Ecosystem Dynamics
• GLRC and Marine Operations
• Marine Technology and Engineering
• Aquatic Resources and Human DimensionsAquatic Resources and Human Dimensions
• Education and Outreach

Focus Area: Fresh Water
• Stewardship of freshwater is one of the most significant grand challenges facing our worldsignificant grand challenges facing our world.
• Approximately 70% of the Earth’s surface is covered by water, but only 2.5% of it is freshwater.
• The Great Lakes are 84% of North America’s surface freshwater with half in Lake Superior.surface freshwater with half in Lake Superior.
• In the Great Lakes region, we face multiple concerns including toxic and nutrient pollution, invasive species, habitat degradation and many others.
What are we… ?
• Shared cutting‐edge equipment:
“Large” and Small Vessel Support
Monitoring Platforms
Advanced Underwater Vehicles
Advanced Sonar Systems

Remote Sensing of Great Lakes Water QualityRemote Sensing of Great Lakes Water Quality
Remote sensing: the collection of data about an object, area, or phenomenon from a distance with a device that is not in contact
ith the objectwith the object.Includes satellite imagery, radar, LiDAR and aerial photos
Several ongoing projects at MTRI apply remote sensing data to g g j y gquestions about Great Lakes ecosystem health Mapping submerged aquatic vegetation (primarily Cladophora) Estimating chlorophyll concentrations & related data across the Great
Lakes (CPAs) Sediment plume mapping Sharing data through GLOS to help monitor Areas of Concern, including
Green Bay Invasive Phragmites mapping Great Lakes coastal wetlands mapping
Partnering with GLOS, NOAA GLERL, EPA GLNPO, NPS, NASA, GLFC, Limnotech, GLC, U-M, USGS GLSC, others
Starting to also share results through GLOS Data Portal (www.glos.us) and NOAA GLERL Coastwatch

Plume Mapping AlgorithmPlume Mapping Algorithm
Generate a robust algorithm for the Great Lakes to map lplumes: Extent
Constituents
Concentration
It can utilize any ocean color aircraft or sensor that has the IR (infrared), Blue and Green bands
In the past sediment plumes were detected with a simple IR/R d ti th MODIS R d b d f th t lIR/Red ratio or the MODIS Red band for the coastal ocean (i.e. Doxaran et al. 2002, Rodriguez-Guzman, Gilbes-Santaella 2009 and Zhao et al. 2011)

Mapping and Monitoring the Extent of Submerged Aquatic Mapping and Monitoring the Extent of Submerged Aquatic Vegetation in the Great LakesVegetation in the Great Lakes
Cladophora, a native, filamentous, green algae that grows in all of the Great Lakes,
i i h 19 0 d hwas a nuisance in the 1970s and has recently staged a comeback
Associated with beach and water intake fouling as well as with the spread of avianfouling as well as with the spread of avian botulism and E. coli
MTRI used Landsat satellite imagery to map the current extent of submerged
ti t ti hi h i i ilaquatic vegetation, which is primarily Cladophora in much of the Great Lakes, in Lakes Michigan, Huron, Erie and Ontario.

Using synthetic aperture radar (SAR) at a 20 m resolution MTRI recently finished mapping theresolution, MTRI recently finished mapping the distribution of invasive Phragmites along Great Lakes coastlines
SAR can differentiate wetland species based on water level patterns, vertical structure, soil moisture, bi d h l i l i ti ( id d b tbiomass, and phenological variation (provided by a set of spring/summer/fall radar images)
•1162 unique field site visits. •796 validation, 366 training
•Phragmites observed at 30% of sites.
• 68% Validation sites• 32% training sites
•Only NWI "Palustrine Emergent"Only NWI Palustrine Emergent polygons used to generate random points for validation sites of these, only 47% were documented as emergent in the fi ld b tifield observations
