Methods Documentation

calc_range()

Calculates range in meters using parameters stored in the .nc file.

calc_sample_thickness()

Base method to be overridden for calculating sample_thickness for different sonar models.

calc_seawater_absorption(src='file', formula_source='AM')

Returns the seawater absorption

Parameters

srcstr

‘file’ will return the seawater absoption recorded in the .nc file ‘user’ will calculate the seawater absorption. Default (Ainslie and McColm, 1998).

Returns

Seawater absorption value

calc_sound_speed(src='file')

Base method to be overridden for calculating sound_speed for different sonar models

calibrate(save=False, save_postfix='_Sv', save_path=None)

Perform echo-integration to get volume backscattering strength (Sv) from EK60 power data.

Parameters

savebool, optional

whether to save calibrated Sv output default to False

save_postfixstr

Filename postfix, default to ‘_Sv’

save_pathstr

Full filename to save to, overwriting the RAWFILENAME_Sv.nc default

calibrate_TS(save=False, save_postfix='_TS', save_path=None)

Perform echo-integration to get Target Strength (TS) from EK60 power data.

Parameters

savebool, optional

whether to save calibrated TS output default to False

save_postfixstr, optional

Filename postfix, default to ‘_TS’

save_pathstr, optional

Full filename to save the TS calculation results, overwritting the RAWFILE_TS.nc default
