Hypoxia and river discharge.

Here is a plot of hypoxia and river discharge. The discharge is measured at Tarbert Landing, and is plotted in 1000 m3/s. The measured bottom hypoxic area is plotted as read lines in terms of area (1000 km2). The length of the lines represent the period over which the data were taken.

New submission of the hypoxia paper

I finally got around to doing my revisions, and sent the hypoxia paper in. You can get it here:

Enjoy.

Test post from Mars edit.

Ok, so my test post from TextMate never amounted to much. Here is another test post from MarsEdit. I think it can handle figures:

(automatically uploaded and linked -- cool). Now I just need better content....

PYROMS on Google code

I have put together some of the python tools I have been writing into a package called pyroms. It is available on google code:

Please contact me if you would like to be on the developer list.

How to make a grid (in python)

I just competed a movie on how to make a grid using pyth0n. The methods, I think, are about the same whatever platform you use. You can watch the movie online, or download the movie.

Simple ROMS case

Below are two movies I made of a seminar on how to create a simple case in ROMS. The case is of a sequentially upwelling/downwelling wind on a shelf. There were some compiler issues, that are not included, so the movie is in two parts (the second part is after the issue got fixed). For the record, it was TS_MPDATA that caused the failure on my laptop (a segfault, then a bus error -- not so good). Using more conventional tracer advection options (Akima 4th order and splines) works great. Here are the links:

• Part 1
  
• Part 2
  

ROMS grid class in Python

I have just finished a beta version of a grid class for ROMS (or other curvilinear C-grids). I have not cut out a release from the svn yet, as I am waiting for comments from others. However, you can see the source code here. You can get the entire toolset from svn with:

svn co http://pong.tamu.edu/svn/python/trunk/ rdh_python

I have also posted an introductory tutorial here. Other tutorials (and a fancier page) will be posted to
