LISICOS & CT DEEP Long Island Sound Water Quality Data
• Development of a sustained capability to observe the Long Island Sound ecosystem and an adequate capability to understand and predict its response to natural and anthropogenic changes.
• Provide easier access to this long term water quality data
• Added value to LISICOS research and provide other parties direct access to these data
About CT DEEP Long Island Sound Water Quality Data
• The Connecticut Department of Energy and Environmental Protection (DEEP), on behalf of the Long Island Sound Study estuary program, conducts a Long Island Sound Water Quality Monitoring Program since 1991
• October to May, water quality is monitored by collecting samples once a month from 17 sites
• Bi-weekly hypoxia surveys start in mid-June and end in September with up to 48 stations being sampled during each survey.
How we manage our data
• CT DEEP maintains in-house relational database
• Periodically this database is ingested into the LISICOS data system using a series of set queries
Data Management Successes
• Allowed researchers to easily access, compare and analyze data
• Comprehensive analysis of DO duration
• Analysis of long term trends of nitrate and phosphorous
• LIS bottom temperature
Data Management Challenges
• Once initial framework was built challenges have been minimal
• Delay in data transfer – Security and time limitation
Take home points
• Allowing data collectors to leverage existing platforms to visualize and serve information
• Broadens user base, saves data management time, provided platform to exploit these data
