Do you work on lakes globally? Check out what is, to my mind, the most complete global database of lakes (~6M) and associated attributes, newly published in WRR. Also the basis for SWOT lake data.

Work with me on getting depth-discrete profiles of water quality using high-frequency loggers and microCTD measurements! And then let’s be creative to infer mechanisms that could improve mechanistic modeling.

We often think of rivers as linear features, but lateral dynamics are just as important and often overlooked! In our paper we present a framework for the study and management of rivers which emphasises lateral connectivity.

The sky above Umeå has been colorful lately (when it's not pitch black that is). Everyone in IceLab has seen these. Except the fish. 🐠 They're just doing their regular fishy things.
