Design and Analysis specifics and examples for Estuaries
Information on Estuaries is organized in the following categories: Objectives & Questions, Target Population, Design, Response Design/Indicators, Analysis Approach, Results. In addition, an example application of the population estimation algorithms is presented based on two year's data for South Carolina's Tidal Creeks and Open Water Coastal Estuaries.- Clean Water Action Plan: Coastal Research and Monitoring Strategy assesses national needs for coastal research and monitoring, and recommends an integrated framework for protecting vital coastal resources.
- South Carolina
- Determine the quality of the ambient environment
- Provide comprehensive, reliable data to SCDHEC and EPA
Target Population, subpopulations
- Florida - Example
- 18 coastal sampling units
- State-wide and Regional Scale
- Strata correspond to Florida's 5 Water Management Districts (WMD) and reporting units (see IWRM Network)
- South Carolina - Example
- Tidal Creeks, identified as < 100 m wide on GIS cover
- Open Water areas, identified as > 100 m wide on GIS cover, represent larger estuarine rivers and sounds
- Estuarine area based on GIS coverages of NWI maps. Monitoring stations represent 41 sq.mi. Tidal Creeks and 243 sq. mi. Open Water areas..
- Oregon Coast Example Sample Sites
- So. California Bight Example Sample Sites
- Florida - Example
- Regional: 5-year Rotating Basins - 30 sites for one Basin per WMD annually
- Statewide: 25 Randomly selected annually, plus 5 randomly chosen trend sites
- South Carolina - Example
- 5-Year Panel Design
- Approximately 30 Tidal Creek and 30 Open Water sites sampled per year
- Biology sampled 15 Sites once/yr, Non-biological sampling monthly all sites
- Two sub-populations, Beaufort and Charleston areas, w/ intensified sampling
- Sampling Sites for 1999-2000
- National Coastal Assessment 2005-2006 Sampling Sites
- South Carolina
- All stations sampled once during index period (mid-June to August)
- Most measures within 2-3 hrs (some time-series up to 25 hrs)
- Water Quality prior to deployment of bottom sampling gear
- Replicate grab samples for sediment and benthic
- Fish & large crustacean trawls -- 0.5 km, open water sites; 0.25 km, creek sites
- South Carolina (Illustrated Example)
- Statistical estimates of proportion of South Carolina's target population within established parameter values
- Estimates from analysis of cumulative distribution functions (CDFs)
- Florida - Example - IMAP Annual Report - Year Two
- South Caroilina - Example
- Integrated Sediment Quality Score
- Percent of Habitat Benthic-IBI
- Integrated Habitat Quality Score
- Overall Habitat Quality Score at Sampled Sites: Northern, Central, Southern Regions
