Amazon Floodplain Macrophyte Biomass and Phenology Measurements 2003-2004

Monte Alegre Lake region on the eastern Amazon River floodplain in Para, Brazil provides the location for this dataset. It contains field measurements of aquatic macrophyte biomass, phenology, leaf characteristics, and stem dimensions for submerged and unsubmerged plants. Data originates from ten monthly surveys conducted between December 2003 and November 2004, compiled in a comma-delimited file.

Use Cases

• Analyzing seasonal biomass variation of submerged and unsubmerged macrophytes across ten monthly surveys.
• Studying plant phenology and leaf characteristic changes in a tropical floodplain lake environment.
• Modeling carbon storage and primary production based on measured stem diameter and length data.
• Investigating the growth dynamics of aquatic vegetation in response to Amazon River flood pulses.

Strengths

• Dataset provides a complete annual cycle with ten field surveys conducted at approximately monthly intervals.
• Measurements include specific plant traits: biomass, phenology, leaf characteristics, and stem dimensions.
• Cross-platform presence on NASA EarthData and Data.gov indicates established curation and importance.

Limitations

• Column names and exact row count are not provided by any source, limiting immediate analysis.
• Conflicting last updated dates exist: one source reports 2004-12-04, while others report 2026-03-13.
• License is ambiguously listed as 'other-license-specified', requiring further investigation for reuse.
