Ecological Data

• Data warehouse of environmental data to support multiple research projects

  • Integrates meteorolgical data from multiple sources

  • River water quality
  • Tides

  • Astronomical data (sun and moon rise and set, phase of moon)

• Quality Assurance/Quality Control Issues in geophysical data

  • Identified and resolved common data inconsistencies such as time zone, daylight savings time, unit of measure conversions.
