GLAMR: The Global LAke Metabolism Respository

Advancing understanding of lake metabolism requires more than just data – it requires linking data to the community in ways that provide both credit for contributions and opportunity to engage in team science.

What is GLAMR?

GLAMR is a centralized, public repository of ecosystem metabolism estimates and related data for lakes, ponds, reservoirs, and other lentic water bodies around the world.

GLAMR includes raw data, derived metabolism estimates, lake characteristics, ancillary data, and rich metadata.

Example data — Example GLAMR data: smoothed daily gross primary production (GPP) and ecosystem respiration (ER) for 58 globally-distributed lakes.

The harmonized GLAMR data set will be published as a data package via the Environmental Data Initiative (EDI).

Why GLAMR?

"Ecosystem metabolism” includes the processes of gross primary production and respiration, by which organisms capture, use, and release energy from the sun. These processes support food webs, determine carbon balances, and power biogeochemical cycles.

Data to estimate ecosystem metabolism are now available for hundreds of lakes and thousands of lake-years. These data are scattered among many published and unpublished datasets. With GLAMR, our goal is to bring these data together in one place to facilitate synthetic analyses.
