I am wondering if anyone knows of an R package to aid to common limnological calculations. I am specifically interested in calculating the position of the thermocline, sizes of the epi, meta, and hypolimnions, thermal stability, etc. I have found the "wq" package which deals with water quality monitoring data on a temporal scale, probably more applicable to lotic (streams, rivers) than lentic (lakes, ponds) systems. I recall coming across something about two years ago which ran these functions through R but at the time I was not familiar with R so passed it up.

What are R Packages? 1 1. Car. This package is Companion to Applied Regression. It is a big package that provides various functionalities for statistical analysis. Importing ... 2 2. Corrplot. 3 3. DataExplorer. 4 4. Gmodels. 5 5. Gplots. More items
At this point, you should be able to install and get the most from your R packages, but there still is one final question the air: where do you find the packages you need? The typical way of discovering packages is just by learning R, in many tutorials and courses the most popular packages are usually mentioned.
If keeping up with the growing number of packages you use is challenging, consider RStudio Package Manager. The tidyverse is an opinionated collection of R packages designed for data science. All packages share an underlying philosophy and common APIs.
dplyr package is used for data manipulations and its providing lots of functionalities like select (), arrange (), filter (), summarise (), and mutate (). If you are dealing web scraping or extracting data from online source then xlm will become handy. XML used For read and create XML documents with R.
It seems like AquaEnv will do all of the things you mentioned (indeed, those are pretty much core functions of this Package.
i don't believe this package is available on CRAN, rather it's on R-Forge; hence, you can download and install it by:
install.packages("AquaEnv", repos="http://R-Forge.R-project.org")
The most recent version (available on R-Forge) was released in 2010-04-09.
I Have used it for simulation work (though it's not a general simulation package) and i was impressed with the numerical stability and with the documentation.
