Formats
This data is available in SMB format (the log file is a internal Neptune Canada format). Log files are created daily at midnight UTC from data acquired throughout the day. Shortly thereafter, the data products are processed from the log files and are made available to data search. Content descriptions are provided below.

Previous versions of the MS1000 software did not directly support the high sample high that our rotary sonars operate at. To make older versions work, right-click on the image and select 'Fit Image To Screen'.
MAT
...
MAT files (v7) can be opened using MathWorks MATLAB 7.0 or later. The file contains four two structures: meta, data, config, and units. Meta : structure containing the following metadata fields.

Data: structure containing the ADCP data, having the following fields.
- date:
- hdr:
- extraHdr:
- overloadCounter:
- sonarData:
- sonarTime:
- sonarAngle:
- settings:
- time: vector, timestamp in datenum format (obtained from time the reading reached the shore station)
- range: vector of distance to start of each bin
- cellDepth: vector, starting depth of each cell calculated from range and deployment depth (may be inaccurate if instrument is vertically mobile)
- u,v,w: 2D matrices, East/North/Up velocities relative to True North, derived using raw velocity matrix, orientation, coordinate system, transformation matrix and one of a) calculated magnetic declination based on time and location (for mobile adcps) or b) meta.deviceHeading (fixed position ADCPs)
- velocity: 3D matrix, corresponds directly to output of instrument and so depends on configuration coordinate system
- amplitude: 3D matrix, amplitude time-series for each of the three receivers
- correlation: 3D matrix, signal correlation coefficient time-series for each of the three receivers (only available for HR-Profilers)
- compassHeading: vector, magnetic compass heading time-series
- pitch: vector, pitch time-series
- roll: vector, roll time-series
- pressure: vector, pressure time-series
- temperature: vector, temperature time-series
- soundSpeed: vector, sound speed time-series (often constant, depending on configuration)
- voltage: vector, battery voltage time-series
- error: vector, error code
