Raw converted data#
The EchoData
object#
EchoData
is an object that conveniently handles raw converted data from either raw instrument files (via open_raw
) or previously converted and standardized raw files (via open_converted
). It is essentially a container for multiple xarray Dataset
objects, where each such object corresponds to one of the netCDF4 groups specified in the SONAR-netCDF4 convention. EchoData
objects are used for conveniently accessing and exploring the echosounder data, for calibration and other processing, and for serializing into netCDF4 or Zarr file formats.
A few example EchoData
objects are presented below. They show the hierarchical structure of the SONAR-netCDF4 version 1 groups for the sonar models currently supported by echopype.
Click on a group to drill down to variables and attributes and to examine the structure and representative content of an EchoData
object.
Depending on the instrument, data variables contained in each group may be different. See the example data sections below and Data from different echosounders for more information.
The echopype version used to render the EchoData objects below is: 0.7.2.dev50+g451d5ef6
Kongsberg Simrad EK60#
EK60 echosounder transmits narrowband signals (gated sine waves) and therefore the Sonar
group contains only a single subgroup Beam_group1

Kongsberg Simrad EK80#
EK80 echosounder can transmit both narrowband (“CW” or “continuous wave”) or broadband (“BB”, or “FM” or “frequency-modulated”) signals.
In echopype-converted files, there can be at most 2 groups under the Sonar
group. The type of data stored in these Beam_groupX
groups follow the scenarios below:
If only complex data (can be BB or CW signals) exist, there exists only
Beam_group1
and this group may contain CW or BB complex data, or a mixture of both. See example below.If only power/angle data (only valid for CW signals) exist, there exists only
Beam_group1
and this group contains CW power and angle data. The structure is almost identical with EK60 data above.If both complex and power/angle data exist, there exist
Beam_group1
(contaning complex data) andBeam_group2
(containing power/angle data). See example below.
Scenario 1#
The example file below contains both CW complex and BB complex data, both stored as complex data. Therefore, there is only Beam_group1
under the Sonar
group.

Scenario 3#
The example file below contains both narrowband (“CW” or “continuous wave”) “power/angle” data as well as broadband (“BB”, or “FM” or “frequency-modulated”) complex data. Therefore there are two groups under the Sonar
group: Beam_group1
and Beam_group2
.
