I'm a microbial ecologist by training here for conversations about #ecology, environmental science, decision making, policy, #rstats, #GIS, and all things water quality. Here to discuss those topics for the most part, but would also love to get to know other lgbt scientists in general.
I work in a small firm as an environmental consultant in Florida, where I focus on water quality related issues for a variety of public and private sector clients.
Follow me for that kinda stuff!
Snapshot of how water quality regulation works: Effluent is low in DO, so 3 downstream sites sampled & associated biology examined to determine if designated use is met. It was met by TRIB-1, so site specific criteria can be put forward for the stream section between the effluent and this first station: no more than 10% of DO can be below established healthy conditions (which is same as regional criteria that is violated, just with a data set of only this site instead). Figure made in #rstats
Hello new scholars! :)
A bunch of new friends joined the instance lately, so it's a good time to remember that the rules here are a bit different from Twitter or even from other Masto's

I learned how to do a new thing in ggplot! Not all that complicated but I like it for visualizing events over time. #rstats
Also if you are into spatial stuff and R, check out the geospatial R tutorials over at @datacarpentry's website. Highly recommend.
Idk buddy. Idk. Where are any of us really? Floating on a spec of dust in the cosmos. Staring at screens. Staring out at the stars. No matter what, we are incomprehensibly dwarfed by the universe. And so, giving up, we stare at the abyss. We attempt to make sense of it. We try to answer questions. where am I? Who am i? What am I? But the abyss is hungry and indifferent to our existence.
And so we get overwhelmed. And go look at cat memes.
Some are trying to help by example. But I fear it might be more of an existential question.
I guess some weeks are just rough for self confidence. Got reviews on two different reports: one where I made a mathematical error (using standard deviation instead of variance) and one where I reported pooled technical reps as averaged. Imposter syndrome kicking in pretty hard right now.
What's amusing about this calculation is that it is an urban ditch, and the calculated criteria is lower than the criteria for reference streams (3.2 ug/L AGM chlorophyll a). Kinda strange!
This results in a very low number for chlorophyll a. The criteria calculated does not rely on a relationship to a biological response due to nutrient inputs, so it is possible that the system "fails" in the future, yet there is no observable degradation of inverts, plants, etc.
The default is to use the 80th percentile, but in this case due to the unequal distribution of data over time, that would cause the site to violate based on existing data. Since the philosophy of this standard is to protect existing conditions, that doesn't work.
