This article provides an overview of the Great Lakes Restoration Initiative (GLRI) and the Environmental Protection Agency's (EPA) use of NOAA's hydrographic services for GLRI implementation. It discusses the importance of up-to-date bathymetric information, bottom mapping, and nearshore sampling in the Great Lakes. The article also highlights other NOAA data services that support GLRI implementation.

EPA & GLRI: An overview of the use of NOAA’s hydrographic services Jackie Adams U.S. Environmental Protection Agency Great Lakes National Program Office
Outline • Great Lakes Restoration Initiative Overview • EPA’s use of NOAA’s hydrographic services and future data needs • Other NOAA data services that support GLRI implementation
Great Lakes Restoration Initiative (GLRI) • Funding Years • FY10: $475 million • FY11: $300 million • FY12: $300 million • FY13: $284 million • FY14: $300 million • FY15: $300 million • FY16: $300 million • FY17: $250 million*
GLRI Action Plan II Focus Areas • 1. Toxic Substances and Areas of Concern • 2. Invasive Species • 3. Nonpoint Source Pollution Impacts on Nearshore Health • 4. Habitats and Species • 5. Foundations for Future Restoration Actions
EPA’s use of NOAA Hydrographic Services • Bathymetry • All R/V Lake Guardian surveys utilize Great Lakes bathymetry maps for survey planning and navigation • Targeting specific depths to capture a range of depositional regimes.
EPA’s use of NOAA Hydrographic Services • Nearshore sampling on R/V Lake Guardian (~20m circumnavigation per lake) • National Coastal Condition Assessment (sample frame design ~30m maximum)
Hydrographic Service Needs • Up to date bathymetric information (at the very least Lake Superior) • Bottom mapping • Nearshore • Open water
Updated Bathymetry • Aids various agencies in terms of navigational and environmental services. • Sea Level Fluctuations • Great Lakes Water Quality Agreement - Annex 2 – Nearshore Framework
Bottom mapping in the Great Lakes • Widely acknowledged need for improved information about the lake bottom • International agreements highlight the need • Great Lakes Water Quality Agreement (1978, 2012) • Nearshore framework, habitat and species • Bottom type, geology, bathymetry, sediment dynamics • Great Lakes Fishery Commission Convention; US and Canada (1955) • Bottom habitat, benthic invasive species
Bottom Mapping Workgroup Aim: Harmonize collection, processing, and sharing of continuous high-resolution maps of bathymetry, sonar reflectance, bottom type, and derived products. Objectives: • Inventory available data and data products • Identify and prioritize geographic gaps in data availability • Inventory mapping capacities and instrumentation • Inventory data user needs • Promote the use of technical guidance and standards • Provide a forum to connect data providers with end users • Promote collaboration Near-term Product: White paper for delivery in Spring 2017
Bottom Substrate Classification • Conventional options • Topographic • Lidar (a detection system that works on the principle of radar, but uses light from a laser) • Alternative Methods • Single-beam system sweeps • Ground-penetrating lidarover ice • Time-Domain Electromagnetic (TDEM) methods
NOAA Fleet • Diversity of vessels is needed to generate the necessary data • NOAA GLERL fleet can be much more adept at doing Great Lakes work; investments in regional fleet needed. • Complementary role of AUVs
Other • Operational forecast system for Harmful Algal Blooms. • Runoff risk advisory tools • Annex 4 - Nutrients • Estimates of HAB biomass, aerial extent and surface scum • Triggers for toxin production • Quantification of toxin levels • Circulation modeling
