Abstract:
The Station Location data set reports information regarding the planned sampling locations designated by MAIA planners for the 1997/1998 MAIA-Estuaries monitoring program.  One record is presented per station.  Each record reports the planned values of latitude and longitude, the MAIA data group nominally responsible for the station, and the partners' original station identifying code.  Each record also includes the names of the estuary, sub-region and state associated with the station, a parameter classifying the station according to the MAIA sampling design, and various statistical weighting factors (inclusion probabilities) used when performing analyses with the data.

  The Sampling Visit data set reports information regarding the actual sampling events in the 1997 and 1998 MAIA-Estuaries field seasons.  The information provided includes the sampling date, latitude, longitude, water depth, the MAIA data group responsible for the sampling event, and the sample visit number.  All records reflect values measured at the time of sampling.  One record is presented per sampling visit. 

The main objectives of the MAIA-Estuaries program are:  (1) to evaluate the ecological condition of the Mid-Atlantic estuaries by measuring key properties of the water, sediment, and the community of organisms;  (2) to focus attention on small estuaries in order to develop better monitoring approaches for these critical systems; and (3) to develop partnerships among federal and state environmental organizations. 

  The Environmental Monitoring and Assessment Program (EMAP) is an EPA research and monitoring program designed to provide unbiased assessments of the condition of selected resources over a wide region.  A key feature of the program is a probabilistic sampling strategy that randomly selects sampling sites and assigns weighting factors based on area to all measured results.  EMAP's strategy was adopted by the Mid-Atlantic Integrated Assessment (MAIA) program, which was designed to assess the conditions of the estuaries, forests, streams and lakes, and agricultural lands in the eight-state Mid-Atlantic region.  This file contains data measured in MAIA estuaries during the Summers of 1997 and 1998.  Samples were collected for water and sediment analyses primarily in 1997, with a few additional sites sampled in 1998.  Fish samples were collected only in 1998.  Several estuaries were designated as intensive sites and were sampled in greater detail.
 
  The partners in MAIA-Estuaries program are: (1) The U.S. Environmental Protection Agency (USEPA), including both the Atlantic Ecology Division (AED) and the Gulf Ecology Division (GED); (2) National Park Service (NPS) under their project "Maryland Coastal Bays Monitoring"; (3) National Oceanographic and Atmospheric Administration (NOAA) which conducted sampling both in the Delaware Bay (DB) under their "National Status and Trends Program" and in the Carolinian Province (CP); and (4) The Chesapeake Bay Program (CBP), which is a consortium of federal, state, and local governments and nongovernmental organizations.  Each partner was responsible for collecting, processing, and reviewing data.  The USEPA Atlantic Ecology Division was responsible for final assembly and review of all data.  Laboratories contracted to process samples are specified by the parameter LABCODE included in all data files (Section 4.4).
Purpose:
STATION LOCATIONS: To report information about the planned location of sampling stations,
  including: latitude, longitude, and area; the names of the estuaries, sub-regions, and states
  containing the stations; and codes that identify the MAIA partner responsible for sampling a
  station and that classify stations according to the MAIA sampling design.

  SAMPLING VISITS: To report latitude, longitude and water depth measured at the time of
  sampling.
