1 U.S. EPA - ORD. NHEERL Atlantic Ecology Division Narragansett, Rhode Island Hal Walker Estuary and Coastal Conditions Reporting Got Data? - Cool Tools for Effective Data Presentation New England Regional Volunteer Monitoring Workshop Friday, November 16th, 2007 EPA New England Regional Laboratory North Chelmsford, MA

2 Got Data? - Cool Tools for Effective Data Presentation Suggested components of presentation 1.Quick intro to what your program is: National Coastal Assessment: 2.Rationale for developing an index (why created) National consistency in reporting on estuarine condition 3.Mechanics of the index (not too much detail – but hopefully with information on how to get more information) NCCR2 4. Examples of how index has been used or will be used National Coastal Condition Reports 5.How successful has it been Outstanding Achievement Award Renewable Natural Resources Fund 6.Lessons learned Consistency in goals, rational, approach, funding. Partnership with States and Tribes key to success. Tech transfer of methods / reproducibility 2

3 Report Cards (Medical example and Watershed Example) National Coastal Assessment Overview (indicators and indices) Example Regional Scale Results (water quality indicators) Example State Level reporting (sediment quality index) “Cool tools” Philosophy (Reproducible Calculations / Flexibility) Computational Approaches (ArcMap, Excel, R-Excel, R script) Excel example, R-Excel example Next steps (adapt computation tools for lakes assessments) Got Data? - Cool Tools for Effective Data Presentation: Defining the Goal, Audience, Computational & Reporting Methods 3 Talk Outline:

4 My son was diagnosed with leukemia at age 6  What are the indicators ?  Do we need additional information on cell type?  What are the treatment options ? Your watershed has problems.  What are the indicators and indices of condition ?  Do we need more monitoring information ?  How do we inform the decision making process ? How doctors think. Dr. Jerome Groopman NPR audio interview Defining the Goal, Audience, Computational & Reporting Methods Have Data: How do we present the data to decision makers ? 4

5 SAMPLES GENES Discrimination between two forms of Leukemia: ALL, and AML From Goulb et at (1999) Heatmap. based on gene expression monitoring by DNA Microarrays. Automatically discovered the AML / ALL distinctions. ALL AML Predicted vs Observed This analysis is reproducible using open source R software

6 Goal for report components: (1) Report, (2) Data, (3) Computational Script “ Smart Monitoring: The River is the Report Card for the Watershed” from Warren Kimball, MA DEP 6

8  Assess the ecological condition of estuarine resources.  Based on unbiased data of know quality  Determine reference conditions for studies on ecological responses / stressors.  Build infrastructure in states and EPA Regions. National Coastal Assessment (NCA) is working in partnership with States Regions and Tribes to: 8

9 Estuarine Assessment & Reporting involves partnerships: EPA ORD NHEERL & OW, NOAA & NMFS, USGS, Fish and Wildlife Service, Coastal States, and Universities Reporting on conditions in Nation’s estuaries and Large Marine Ecosystems Improvement in consistency in assessments required by the Clean Water Act (CWA) 9

10 National Coastal Condition Reports (NCCRs) are based on probability survey and advisory data from regulatory agencies Large Marine Ecosystems (LMEs) NCA receives EPA ORD “Team Work Award”, 2007 Offshore surveys 10

11 NCA Partners in Northeast Chesapeake Bay Program Suffolk County DHS AED receives ORD Statesmanship Award, sampling designs by water body States share sampling regional data sharing frequent meetings

12 Approach:  Utilize consistently measured indicators to assess and help explain estuarine condition  Utilize Probability surveys  Extrapolates to all of estuarine waters  Addresses 305(b) requirements & GPRA  100% assessed waters  Incorporate existing monitoring programs, & develop hybrid monitoring designs National Coastal Assessment 12

13 Surveys in the Northeast estuaries from 2000 thru 2006 Production of a series of National reports Technology transfer from EPA ORD to EPA Regions, Office of Water, States and Tribes Data sharing within the Northeast Region Use of environmental indicators, indices, and tech transfer of “computational tools” National Coastal Assessment 13

14 Analysis and Reporting National Coastal Condition Reports National Estuary Program Coastal Condition Report In Nov 2007 U.S. EPA National Coastal Assessment to receive “Outstanding Achievement Award” Renewable Natural Resources Fund 14

15 Water Quality - dissolved oxygen - salinity - temperature - pH - depth - light attenuation - secchi depth - dissolved nutrients - chlorophyll a - total suspended solids (TSS) Sediment Quality - sediment contaminants. (organics & metals) - sediment TOC - sediment toxicity (amphipod) - percent silt/clay Biota Fish/Shellfish -community structure (fish) - tissue contaminants (organics & metals) - external pathology (fish) Benthos - community structure Habitat - SAV (presence/absence) west coast & gulf coast - basic habitat type (e.g., open water, tidal flat) - marine debris (presence/absence) Consistently Measured Indicators Coastal 2000 / NCA Core Indicators: Not Measured by NCA - SAV SAV condition -Macro algal biomass -Harmful algal blooms -Biomass of sensitive and tolerant taxa 15
