History of the course

Early versions taught by Christensen, Peacock. Then no one for a while until the 1997 course!. Ramón taught it again in 1999 and then Ed Garnero took it over in 2000 and it was taught by Garnero, McNamara, or Semken. Ramón taught it in Fall 2007, and then with Matt Fouch in 2009. Fouch and Garnero taught it in 2010. I taught it again in 2011.

2011 statement:


Adam experience and motivation:

I completed my B.S. degree in Geological Sciences at the University of Oregon, and I am currently working on my Ph.D. in Geological Sciences at ASU. My Ph.D. will say “Geological Sciences”, but I am really a hydrologist now who is interested in the interaction of hydrology and the critical zone. The broad topic of my dissertation is investigating how hydrology affects the ecosystem state, and vice versa. I am currently working on a project to test how hydrologic controls give certain plants advantages and affect the process of woody-plant encroachment in the American Southwest. My datasets are very large (I have over 4 billion data points), so I use several different computer programs and scripts to process the data. I measure the full hydrologic cycle (rainfall, runoff, evapotranspiration, and soil water) as well as many meteorological variables, so computers are necessary to process all of this data. I primarily use Matlab to work with this data. I also use computer models to model the hydrology of my study basin. I have used models that run through Matlab, ArcGIS, or are coded in C++ and run through a terminal. I have found that once you understand the basics of how computer language works it is pretty easy to transfer that knowledge to a wide range of applications.

Basic ideas of networking

What is the difference between what is on your computer and what is on a different computer and where is that computer?

Assignment 1: Getting some information

Introductory poll for the class.

Assignment 2: Setting up a web page at ASU

Before coming to class on Wednesday, you must set up your personal web space on the ASU servers: See this link. If you prefer, or you already have something similar running, you may use to build your web space elsewhere.
