RFA: Environmental Indicators in the Estuarine Environment Research Program (2000)
Research Category: Ecological Indicators/Assessment/Restoration
Description:
Objective:The objectives of this research project are to: (1) enhance the archive of existing data for these systems with remotely sensed and time-series information on key water quality and habitat condition variables; (2) exploit detailed knowledge of ecosystem structure and function to synthesize this archive and develop candidate indicators; and (3) test the ability of these indicators to gauge ecosystem health and unambiguously detect trends resulting from both natural variability and anthropogenic stresses in multiple estuaries.
Progress Summary:We report on continuing progress on the development, testing, and application of integrative indicators of ecological condition, integrity, and sustainability across the four representative estuarine systems on the Atlantic coast of the United States (see Figure 1) and other estuarine systems where these indicators are being employed in water quality monitoring and habitat characterization programs. The Atlantic Coast Environmental Indicators Consortium (ACE INC) core estuarine ecosystems include the Nation’s two largest estuarine complexes, Chesapeake Bay, MD/VA, and Albemarle-Pamlico Sound, North Carolina; a small estuary, the Parker River, situated in the Plum Island National Science Foundation (NSF) Long-Term Ecosystem Research (LTER) site in Massachusetts; and a river-dominated system in the southeast Atlantic Bight, the North River Inlet, South Carolina. These sites are representative of three primary producer bases (intertidal marsh—Plum Island and North Inlet; plankton dominated–Chesapeake Bay and Pamlico Sound; seagrass dominated—portions of Chesapeake Bay and Pamlico Sound). These systems also support ongoing, long-term water quality/habitat monitoring programs, serving as the databases for indicator development and testing. These systems contain both pristine and anthropogenically impacted waters. In addition, ACE INC investigators have established collaborations with university, U.S. Environmental Protection Agency (EPA), and other agency (National Oceanic and Atmospheric Administration [NOAA], National Aeronautics and Space Administration [NASA], U.S. Department of Agriculture [USDA], U.S. Geological Survey [USGS]) researchers working in Galveston Bay, Texas; Florida Bay, Tampa Bay, Appalachicola, Pensacola, and Escambia Bays, and the St. Johns River Estuary, Florida; the Mississippi Delta and adjacent Northern Gulf of Mexico; the San Francisco Bay-Delta region, California; and the Great Lakes region where additional testing and application of these indicators are underway.
Figure 1. ACE INC Research Sites Include: (A) The Plum Island Estuary in MA, an NSF LTER Site; Two of the Nation’s Largest Estuarine Complexes: (B) Chesapeake Bay and (C) Albemarle-Pamlico Sound (Both Designated Coastal Intensive Site Network [CISNet] Sites); and (D) North Inlet, a Pristine Marsh-Estuarine Complex in the Southeast Atlantic Bight (Also a CISNet Site, a NOAA National Estuarine Research Reserve System [NERRS] Site, and an NSF Long-Term Research in Environmental Biology [LTREB] Site)
Key areas of research progress that will be elaborated on in this report include:
- The development of indicators of bacterial, microalgal, and macrophyte functional groups controlling primary production, nutrient cycling, ecosystem integrity, and health.
- The development of indicators capable of determining plankton and fish community structure (organization) and function (i.e., indices that relate to trophic transfer and sustainable higher trophic levels).
- The development of biological indicators coupled to physical-chemical and remote sensing assessments of ecosystem function, trophic state, and change.
- The development and application of indicators and assessments within a national coastal indicator framework (EPA-Estuarine and Great Lakes [EaGLe] Program) by establishing collaborations with other EaGLe Centers and EPA/NSF/NOAA-supported ecological indicator research efforts.
The indicators we are examining form the backbone of ecosystem, regional, and national water quality, habitat assessment, ecosystem integrity and health, and living resources monitoring and modeling efforts (see Table 1). These indicators are used to calibrate and ground truth aircraft and satellite remote sensing of estuarine and coastal resources, including plant community structure, function, ecosystem function, and overall ecological condition. Microbes, microalgae, marsh, and seagrass proxies are being linked with metrics of trophic structure to provide indicators of living resources status.

Collaborative Efforts With Other EaGLe Centers and EPA Cooperative Centers
- Development of bio-optical and ecological indicators of seagrass community productivity, structure, and health (with C. Gallegos, Atlantic Slope Consortium [ASC]).
- Use of neural network analysis to predict phytoplankton community structural and function responses to hydrologic and nutrient stressors in estuaries (with P. Noble, Consortium for Estuarine Ecoindicator Research for the Gulf of Mexico [CEER-GOM]).
- Application of diagnostic photopigments as indicators of phytoplankton functional groups in estuarine and coastal ecosystems (R. Axler, Great Lakes Environmental Indicators [GLEI] Project, R. Snyder, CEER-GOM, D. Millie, Florida Marine Research Institute).
- Exploration of the use of diagnostic photopigments as indicators of benthic and epiphytic microalgal community structure (with G. Cherr, Pacific Estuarine Ecosystem Indicator Research [PEEIR], R. Snyder, CEER-GOM).
- Coupling of estuarine phytoplankton, seagrass, and turbidity indicators to aircraft-based advanced high-resolution imagery (Pamlico Sound, NC with R. Lunetta, EPA-Research Triangle Park).
- Molecular indicators of ammonification and nitrification dynamics in coastal waters (with J. T. Hollibaugh, PEEIR).
- Statistical approaches for utilizing phytoplankton functional group as indicators of hydrologic and nutrient forcing features in estuaries (with R. Regal, University Minnesota, Duluth, GLEI).
- Application of neural network analysis to classify land cover (with investigators from CEER-GOM and ASC).
- R. Torres is working with the NSF-sponsored National Center for Airborne LiDAR Mapping to create a LiDAR Digital Elevation Model of the North Inlet Marsh.
- Biomass size spectra approaches to categorize ecosystem status (with C. Rakocinski, CEER-GOM).
Other Collaborative Products
ACE INC is teaming up with the ASC (H. Paerl, R. Torres and D.H. Wardrop, Co-Chairs) to organize a Special Session at the 2004 American Society of Limnology and Oceanography (ASLO) Summer Meeting in Savannah, Georgia (June 13-17, 2004), entitled “ Indicators of Environmental Condition and Change Along the Freshwater-Marine Continuum.”
More than 20 abstracts from EPA EaGLe and numerous other investigators have been accepted, and this session will run for 2 days (June15-16). In addition, at least 10 poster abstracts have been received. As of April 1, 2004, it was the most heavily subscribed session for the ASLO meetings, attesting to the broad interest and work in this research and management area.
EaGLe Data and Metadata Archiving Effort
Postdoctorate L. Valdes of ACE INC has been working closely with data representatives from each EaGLe Center to develop ways to archive adequately the data and metadata collected by EaGLe investigators during the funding period. The EaGLe data committee (EDC), which is comprised of one data manager from each EaGLe Center, was created immediately following the 2002 EaGLe Annual Meeting, where the need to archive and store the large amounts of high-quality EaGLe data that are being collected became apparent. This way, the data can be made available to future investigators. This was particularly necessary for the long-term monitoring data sets that can be used as important baseline information in future studies. To make the data sets useful and to ensure their correct interpretation in the future, each data set requires proper metadata. Metadata is information about the data set and includes items such as purpose of data collection, geographic coverage, reasons for station selection, and so on. The EDC thus has collaborated with the EPA Environmental Information Management System and the Computer Sciences Corporation to develop an EaGLe modified version of the Federal Geographic Data Committee metadata standards that represent not only geospatial data, but also other EaGLe data types, including biological data. The EDC has been involved in the development of Web-based metadata tables based on these standards. The EDC will begin to archive EaGLe data sets and their associated metadata during 2004.
Future Activities:We will continue to: (1) enhance the archive of existing data for these systems with remotely sensed and time-series information on key water quality and habitat condition variables; (2) exploit detailed knowledge of ecosystem structure and function to synthesize this archive and develop candidate indicators; and (3) test the ability of these indicators to gauge ecosystem health and unambiguously detect trends resulting from both natural variability and anthropogenic stresses in multiple estuaries.
