This post is a quick example on how to use the World Ocean Atlas database.
Recently I found myself re-creating several of the figures I use in my slides for the Introduction to Physical Oceanography course. My final goal is to create a repository with all the slides for the ...
Several people brought to my attention that the current shapefiles hosted at
GADM are not up-to-date as the one I plotted. Well,
they where in the past (just look at their front figure).
Apparently they updated to the same bad boundaries that are present in GMT and basemap. Unfortunately I ...
shapefile.
Every now and then we stumble upon some weird custom binary file containing that precious piece of data. This post show how to read the weirdest one I have see so far.
My former advisor had all his data stored in a custom binary format he called
OASP (instead of ...
I'm re-factoring the python-oceans module. The first step was to create another module just for the CTD tools (python-ctd)
The new module is already at PyPI and the API will remain the same as before.
To install it type:
pip install ctd
Now we can import the module:
This example is a modified version of the inset example from the geophysique blog.
import numpy as np
import numpy.ma as ma
import matplotlib.pyplot as plt
from oceans.datasets import etopo_subset
We need to import Basemap, Polygon and inset_axes:
from mpl_toolkits.basemap import Basemap ...
Jakecob Vanderplas Sketch Path Filter
got into the core of matplotlib 1.3.
Now it is easy to produce plots with the XKCD style with just the following:
import matplotlib.pyplot as plt
plt.xkcd() #<- That's it!
You will need the ...
The easiest way to obtain the ctd.py module used in previous posts is to
download the source code for
the oceans python module and add the python-oceans/oceans directory to your
PYTHONPATH similar to what we done for the python-gsw.
To clone the repository using mercurial type:
hg clone ...
The python-gsw module, used in some of my previous posts, is an incomplete and unstable version for the Matlab gibbs toolbox. Because it is in constant development the best way to obtain it is to go straight to the source code.
The TEOS-10 primer is an excellent place to start ...
AVISO Altimetry data is available in two formats, gridded and along-track data. Sometimes the along-track data is desirable, instead of the gridded data, to augment hydrographic data. The along-track has a higher spatial and avoids the several assumptions made for the grid interpolation.
This example helps to find the nearest ...
