Description
LBA-ECO ND-07 reports dissolved nutrient concentrations, dissolved oxygen, alkalinity, conductivity, turbidity, and pH from water samples collected in Brasilia, Brazil. Data were collected from nine streams across forest, agricultural, and developed landscapes, plus wells, lysimeters, surface runoff, and precipitation from four sites between September 2004 and December 2006. The dataset comprises three comma-delimited files documenting the impact of land cover on freshwater chemistry.
Use Cases
Analyzing the impact of land cover type (forest, agricultural, developed) on stream water chemistry.
Comparing nutrient concentrations and physical parameters (pH, turbidity) across different water sources (streams, wells, precipitation).
Modeling temporal changes in hydrochemistry over a multi-year period with bi-weekly to monthly sampling.
Assessing baseline water quality for forested catchments versus agricultural and urbanized areas in the Cerrado region.
Strengths
Contains data from multiple water sources (streams, wells, lysimeters, runoff, rain) for comparative analysis.
Covers a defined time range of over two years (September 2004 to December 2006) with regular sampling intervals.
Explicitly documents land cover context (natural, rural, developed) for each sampling location.
Limitations
Column names and exact row counts are not provided in the available metadata, limiting immediate usability.
The license is ambiguously listed as 'other-license-specified' without clear terms.
There is a conflict in the 'last updated' date between platforms (2006 vs. 2026), suggesting potential metadata inconsistency.
