I wrote an R script for calculating MPN. The Most Probable Number [https://en.wikipedia.org/wiki/Most_probable_number] (MPN) method is a long-standing way of calculating the concentration of bacteria in a sample (usually expressed as cells/100 mL). Its distinctive is that it doesn't require a quantitative
This post is intended to complement the previous one [https://danbscott.ghost.io/diy-co2-aq/] with a more theoretical look at dissolving carbon dioxide in water. I wrote a script in R to draw a Deffeyes diagram. This diagram shows the interplay between CO2, pH, and alkalinity [https://en.wikipedia.org/
One of the highlights of my trip to the West Coast [https://danbscott.ghost.io/seattle-trip-2015/] was spending a long weekend in Olympic National Park with a couple of friends. This enormous park (bigger than the state of Rhode Island, apparently) has everything from mountains, to temperate rainforests, to coastline.
Non-parametric statistics are something that I don't recall learning much about in any classes I took—just picked them up from my advisors and literature I read while I was working on my master's thesis [https://danbscott.ghost.io/my-masters-thesis/]—but they're something I think more people should be aware
I previously [https://danbscott.ghost.io/up-the-creek-with-a-paddle/] blogged about an expedition [http://riogrande.texastribune.org/] to travel the entire length of the Rio Grande, by reporter Colin McDonald. That expedition has now come to an end [http://www.texastribune.org/2015/01/27/disappearing-rio-grande-expedition-recap/] , having reached its destination: the Gulf
This post is a continuation of the previous one [https://danbscott.ghost.io/a-home-made-probe-for-dissolved-solids-in-water/] on making a homemade probe for dissolved solids in water. Here I explain how I calibrated it after I got it working. After printing off a new probe tip [http://www.thingiverse.com/thing:440005], I
