Methane Releases from Amazon Hydroreservoirs 2000-2001

Methane fluxes and isotopic data were measured at the water-air interface and in sediment bubbles from two Amazonian reservoirs, Tucurui and Samuel, between June 2000 and September 2001. The dataset includes concentration and isotopic analyses to compare methane cycling in deep versus shallow hydroreservoirs. This study was conducted under the LBA-ECO project and is hosted by NASA.

Use Cases

• Comparing methane oxidation efficiency between deep and shallow reservoirs using concentration and isotopic data.
• Analyzing the relationship between water depth and methane flux at the water-air interface.
• Studying methanotrophic activity levels in Amazonian hydroreservoirs.
• Investigating the isotopic signature of methane released from sediment bubbles.

Strengths

• Data collection spans a 16-month period from June 2000 to September 2001, providing seasonal context.
• Includes comparative analysis from two distinct reservoir sites in the eastern and western Amazon.
• Contains isotopic signals for methane, enabling analysis of microbial oxidation processes.

Limitations

• Exact row counts, column names, and dataset size are not provided by any source.
• Sources conflict on the last updated date: Data.gov lists 2026-03-13, while NASA Earthdata lists 2001-09 -30.
