As a carbon #biogeochemist who is mostly aquatic and focused on organic matter I love being able to dust off my min/pet brain cells and consider a change in focus area.

Ace Frehley, may he rest in rock, was my favorite guitarist. A nice article, but c'mon (and love me) - "I Was Made for Loving You" was not "sparking a metal fever" in its prime. It's disco.

Ace Frehley, legendary Kiss guitarist, dies at 74
The cause of death wasn't immediately released. Frehley fell in his studio in September and had recently canceled his 2025 tour dates.

Federal research funding isn’t just for the benefit of scientists.
A key part of many NSF grants requires researchers to share their findings with the public, including K-12 students. This “broader impacts” component helps make science more accessible while benefiting society🧪

Basic research advances science, and can also have broader impacts on modern society
Basic research that doesn’t have a specific industrial or experimental application still adds value outside the lab by engaging people with exciting research.

Happy to share our new paper in Biogeochemistry!
We show that CDOM changes at low salinities due to flocculation, potentially making it a less reliable tracer in estuaries. We also introduce a new fluorescence metric: the red shift ratio.
