Greenhouse gas emissions from ponds and shallow lakes

In a new paper published in the journal Limnology and Oceanography, (pdf here), we looked at spatial and temporal variability in greenhouse gases (methane and carbon dioxide) in 30 ponds and shallow lakes around the world. Led by Dr. Nick Ray (Cornell University), we found that the smallest ponds had the biggest greenhouse gas concentrations, likely due to the the physical mixing (or lack of) in those small ponds. This supports the idea that the smallest waterbodies have a large affect on the role of freshwater in the global carbon cycle.

This research was done in collaboration with scientists from the Global Lake Ecological Observatory Network originated with the Pond Observation aNd Discovery in GLEON (PONDING) group led by Dr. Meredith Holgerson (Cornell University) and Dr. Richardson.

    The “FNF vs. Whitty” mod is one of the most famous expansions. Whitty – the bomb-headed guy – brings fast and powerful music. This is a classic challenge that every fnf game fan has experienced to test their reflexes.

    Reading about the science behind our local ecosystems really makes me think more about the energy choices I make at home. It’s encouraging to know there are companies out there trying to offer cleaner options; for instance, exploring what American Power and Gas offers has been a simple, positive step for my household, helping us feel a bit better about our footprint. It’s one of those small changes that brings a surprising sense of personal calm, knowing we’re aligned with bigger environmental needs.
