1. Benjamin Jessup. Tetra Tech, Inc.
The Ecological Data Application System (EDAS) for upload of biological data to STORET
EDAS first developed in 1997 to support biocriteria development for states.
Since then several state biomonitoring programs have requested customized versions.
Leading to our current release “version 3.2” that has many features to support biological data analysis.

2. Bug-thinking in EDAS ” Why use EDAS? “ Do your Or “Bio-thinking”
EDAS is analytical, interactive (very flexible depending on your knowledge of ACCESS)
Allows you to ask and answer questions about your data (flexible query design)
Biological metrics especially – enumeration of taxa groups and characteristics
18 states and additional regional agencies are now using EDAS

3. Ecological Data Types
Metadata for Programs, Projects, Station, Samples, Replicates, Personnel, and Methods
Taxonomic census data for Benthic Macroinvertebrates, Fish, and Periphyton
Water Quality
Habitat Assessments
Physical Characteristics
Pebble Counts
Cross-sections
Also trips and visits

5. Modified for Alaska /ENRI program

6. Data Entry

7. Taxa Characteristics Review
Navigate and Update the List
Taxon Characteristics
Taxonomic Hierarchy
Graphics
Referential Data

8. Metric Calculations

9. 126 Stations, 312 Samples, 336 taxa collected from 1997-2000

10. Alaska Data Uploads ENRI of UAA working with ADEC
Biocriteria Development project
Cook Inlet as pilot region
5474 biological results
966 water quality results
ENRI under contract to ADEC,
Collecting benthic and field chemistry samples in limited areas (Cook Inlet, Southeast),
Developing biological criteria,
ADEC coordinating statewide STORET input,
Several smaller entities/agencies contributing to data collection efforts (for biological samples),
Database expertise within the smaller agencies is insufficient (?)

11. EDAS and STORET
EDAS incorporates STORET conventions and codes for sample types, methods, etc.
Batch files are prepared in EDAS, exported to a text file, and imported in STORET
EDAS currently supports data transfer for benthic macroinvertebrate and water quality data

12. Preparation for Batch Upload
EDAS
Required fields completed with meaningful data
Sample and Biological units uniquely identified
Sample IDs, Replicate IDs, Method IDs, Personnel
Characteristic Groups and Row IDs
STORET
Metadata entered for:
organization, stations, taxa, personnel, methods, etc.
Determine complete replacement or partial upload

13. Batch File Generation

14. Error Reduction

15. Save batch file to text file

16. STORET Batch Upload
Dialogue from STORET screens

17. Future Developments Support for upload of other data types
Coordination with SIM
EDAS Analysis Pack for STORET
