PyXPR (Python-based eXpendable Probe Reader) offers functionality for reading data produced by expendable oceanographic profilers/probes and stored in Lockheed Martin Sippican MK21 Export Data Format (EDF).
The following probe types are currently supported, and the code can be readily extended to handle new types:
- eXpendable Bathymetric Thermograph (XBT) probe
- eXpendable Conductivity, Temperature, and Depth (XCTD) probe
- eXpendable Current Profiler (XCP) probe
In addition to the Python 3.x environment, PyXPR depends on the NumPy module. This can be installed using the Python package manager pip:
pip install -r requirements.txt
Installation can be achieved using Python's setuptools module by running:
python setup.py install
Alternatively, on Linux platforms, add the module to your PYTHONPATH environment variable:
export PYTHONPATH=$PYTHONPATH:/path/to/pyxpr
The relevant module for the probe type of interest must first be imported and an object instantiated. The read method should then be called with the path to the EDF file provided as an argument. The data for the different fields, such as temperature, will then be stored as attributes.
An example is given below for the case of XCTD probes:
from pyxpr.xctd import XCTD
xctd = XCTD()
xctd.read("/path/to/edf_data_file.edf")
print(xctd.temperature)
