Tools to load hydrographic data as DataFrames

python-ctd

Tools to load hydrographic data as pandas DataFrame with some handy methods for data pre-processing and analysis

This module can load SeaBird CTD (CNV), Sippican XBT (EDF), and Falmouth CTD (ASCII) formats.

Quick intro

conda install ctd --channel conda-forge

pip install ctd

and then,

import pandas as pd
import ctd

cast = pd.DataFrame.ctd.read_cnv('g01l06s01.cnv.gz')
downcast, upcast = cast.split()
fig, ax = downcast['t090C'].plot_cast()

We can do better:

downcast, upcast = cast.split()

temperature = downcast['t090C']

fig, ax = plt.subplots(figsize=(5.5, 6))
temperature.plot_cast(ax=ax)
temperature.remove_above_water()\
           .despike()\
           .lp_filter()\
           .press_check()\
           .bindata()\
           .smooth(window_len=21, window='hanning') \
           .plot_cast(ax=ax)
ax.set_ylabel('Pressure (dbar)')
ax.set_xlabel('Temperature (°C)')
