Checking PAR sensors before they go into Lake Ontario. While we can't bring the sun indoors, the tunable light source in @AlgaeBurger lab is a great stand in. 6 down, only 10 more to go....

Finally getting around to cleaning up some particulate P samples from the #GrandRiver to explore oxygen isotope signatures in different fractions

#WinterLimnology is cool! Last weekend, my #IceDiving collaborators practised installing my sympagic enclosures on the #LakeIce bottom in #GreatLakes #LakeHuron. They even edited in some inspirational "underwatery" music.

Here is one of many at @LakeErieNorth, and another by @LakeSuperior marching for science, and sharing the @NatGeo article his human dad was in. He's really an ambassador for all lakes - and lake sceince

If you love plants and water, you’re in for a treat on this Valentine's day! My #PhD paper with @Water_Rox is out in @GlobalChangeBio! We looked at global trends and drivers of submerged #macrophyte quantities in lakes. @GRIL_Limnologie @NSERC_CRSNG doi.org/10.1111/gcb.16619

If you ever wondered how much light penetrates through #LakeIce and snow, this is our “unmodified snowpack” site, inside a black ice fishing shelter. The light is what has passed through the ice and reflected. The productivity array is clearly visible 2m down. #WinterLimnology

.@BobbyHristova just said "more fog than a Whitesnake concert" which really should have been the headline
