New York State Mercury Synthesis: Sample Event Records (1969-2017)

Sample event data from a statewide synthesis of environmental mercury concentrations and loads in New York State, compiled from recent NYSERDA-sponsored monitoring and historical research. The dataset contains records from 1969 to 2017, detailing sampling events, locations, and subjects. It is one of eight related datasets produced by the New York State Energy Research and Development Authority (NYSERDA).

Use Cases

• Analyzing temporal trends in mercury sampling by filtering and grouping records by the 'Year' column.
• Mapping the spatial distribution of sampling sites using the 'Latitude' and 'Longitude' coordinates.
• Identifying the types of environmental media sampled, such as water, fish, or birds, using the 'Medium' and 'Subject' columns.
• Correlating sampling events with specific research projects via the 'Project_ID' and 'Institution' fields.
• Assessing sampling frequency and location context using the 'Waterbody_Type' and 'Capture_Loc' columns.

Strengths

• Provides a multi-decade temporal scope, covering sample events from 1969 to 2017.
• Includes precise geospatial coordinates ('Latitude', 'Longitude') for mapping and spatial analysis.
• Compiles data from multiple monitoring projects and institutions, indicated by 'Project_ID' and 'Institution'.
• Is part of a broader eight-dataset synthesis effort, suggesting a structured research framework.

Limitations

• Key metadata such as total row count, file size, and specific license are not provided by any source.
• The 'last updated' dates provided by the platforms (2026-03-30, 2026-04-04) are implausible future dates, casting doubt on metadata accuracy.
• One source (datagov) lacks column information, preventing a complete column-level analysis from that platform.
