For those unfamiliar with Chaoborus, the phantom midge, here is a larval one swallowing a copepod.

Chaoborus in lakes - that brings back some fond memories: http://www.nrcresearchpress.com/doi/abs/10.1139/f80-098#.WMxZAEu7YiE Anyway, if these guys are messengers of methane, how about planting some fish to keep their numbers down? World wide aerial planting of fish should do the trick. Maybe we can team up with the SRM planes/rockets - death to global warming from above and below ;-) On the other hand, if Chaoborus do stir up the sediment as bemoaned in the article, that's not a bad thing from a methane standpoint. Stirring up sediment increases aeration and suppresses methane production(?) Test - section off a lake into 4 sections 1)+Chaoborus, -fish, 2) +Chaoborus, +fish, 3) -Chaoborus, + fish, and 4) -Chaoborus, -fish. Which one gives off the least methane? OK, maybe you'd need 4 lakes, each with a different treatment. To be a well-funded, biogeochemistry/ecology graduate student again…. Anyway, I'll be in Geneva in late April, and could check in with the lead author for a full debriefing.

Fly larvae in freshwater The gist: a particular species of fly uses methane to keep its larva near the surface in freshwater. That is about 2k to 130k larva per 1 meter2 of freshwater. But methane use by the larva increases in dirty water. So keep freshwater from becoming dirty e.g. agricultural run-off might decrease methane release from freshwater… Summary at: https://www.sciencedaily.com/releases/2017/03/170314081612.htm Abstract at: http://www.nature.com/articles/srep44478 Question: Is this research being overly hyped or is decreasing methane release even a few percent from freshwater a Very Big Deal? -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
