Page 4: About This Guide
1 About this guide This guide begins with a ‘Quick start’ section to help you get going with your new SoundTrap, including software installation and basic deployment instructions. This is followed by several sections containing more detailed information around operation, deployment, maintenance and troubleshooting. It is highly recommended you read the entire guide to ensure you have a good understanding of the instrument and how to get the most from its capabilities. -

2 Quick start guide 2.1 Opening and closing the housing Before opening an underwater housing always check for flooding by shaking and listening for water sloshing around inside. If flooding is suspected, then be aware that the housing may be pressurised and therefore potentially dangerous. - Page 6 • Engage the locking screw by turning anticlockwise with supplied hex key until screw is snug against the housing. • Warning - over tightening the locking screw can cause the housing to leak. Stop once it is snug against the housing, no force is required.

Page 7: Batteries
2.2 Batteries BATTERY WARNING. Lithium ion batteries may explode or burn due to improper use. Careful attention should be paid to your battery suppliers safety recommendations. The SoundTrap ST600 is powered by up to 12 Panasonic NCR18650B (flat top) lithium-ion batteries. These are loaded individually, meaning you can use anything from 1 to 12 batteries depending on desired length of deployment. -
Page 8: Memory
2.3 Memory The SoundTrap ST600 series have capacity for up to 4 microSD cards. Important things to note about memory: 1. You should only use the recommended memory cards – Samsung Evo MicroSD (up to 512GB). All Evo card types are fine, including Evo, Evo plus, Evo Select. Counterfeits of these cards exist, so only source from reputable suppliers. -

2.4 Install the SoundTrap host on your PC To start using your SoundTrap you’ll need to install the SoundTrap Host software. For correct operation of your ST600 it is critical to use SoundTrap Host version 4.0.0 or later. • Pre-installation Notes: o The SoundTrap host software supports Windows 7,8 &... - Page 10 Figure 4 - The Device List...

2.6 Check SoundTrap Status Note the ‘Status’ panel on the right (Figure 4). Carefully review the state of memory and batteries in the right-hand pane, checking that all batteries show 100% charge and all memory show 0% used.

• For faster download in the field, or to save disk space, un-check the ‘Decompress’ checkbox. This will disable the decompression step of the offload process, meaning you will end up with ‘sud‘ files only. These can be decompressed into wav files at a later time using the ‘File Extraction’... -
Page 16: Calculation Of Deployment Endurance
3.2 Calculation of deployment endurance An excel spreadsheet is provided on the website to help with the calculation of deployment times for differing deployment parameters. The spreadsheet provides deployment estimates, as well as identifying one of three possible deployment constraints: battery capacity, memory capacity, or file count. -
Page 17: Clock Details
Compatible hydrophones can be obtained from High Tech Inc USA with model code: HTI-96-MIN/3V/Low Noise/SoundTrap/-165dB. This model has bandwidth of 30 kHz. For higher frequency models we recommend discussing your requirements with HTI. Is is critical that unused channel connectors are protected with dummy wet plugs. Failure to do so will result in damage. -
Page 18: Depth Rating And Prv Requirements
The anchoring scheme used is very dependent on the goals of the data collection in combination with the deployment environment. Thankfully SoundTraps are more easily deployed than traditional acoustic recorders due to their small size. A SoundTrap ST600’s weight in water is approximately 1.2 Most often the hydrophone is located near the sea floor, using an anchored line. -

250 Hz, performed for both low and high gain settings. The calibration data is not shipped with the hydrophone, but instead made available online from the calibration page of the Ocean Instruments website http://www.oceaninstruments.co.nz/ The calibration data is provided as an end-to-end value. This measure is provided for both high and low gain settings, and represents the SPL that will result in a normalised (±1.0) wav file with a... -

as 2.0 V. PAMGuide PAMGuide provides several convenient calibration schemes. For SoundTrap data select the end- toend calibration type and enter a system sensitivity of the calibration value * -1.0 (eg -176.0). Audacity Audacity reports SPL in units of dB re full scale. To scale SoundTrap data use the following: Value in dB re 1 uPa = audacity value + end-to-end calibration –... -
Page 23: Soundtrap Hf Click Detector (St600Hf Only)
SoundTrap HF Click Detector (ST600HF Only) The SoundTrap ‘HF Click’ Detector is a general purpose high frequency click detector followed by a snippet extractor. The detector is designed to detect most odontocetes and is intended to be used as a first pass, guiding you to times in your recordings with lots of transients. You would typically use the detector with a low detection threshold so that it makes a lot of false detects but also detects most genuine clicks (i.e., high sensitivity, low specificity). -
Page 24: Snippet Extractor
4.1.2 Snippet extractor For each detection, an entry is added to the detection log and a snippet of wideband sound surrounding the detection time is saved. The snippet starts and ends a user-selectable time before and after the detection (user parameters: pre-trigger and post-trigger). Evidently, saving longer snippets per detection means that the memory is used up more rapidly so this feature allows the user to trade-off the amount of context that is saved for each detection against the total recording time. -
Page 25: Output File Formats
Blanking time: Time that must then elapse after a detection before another detection can be made. Useful to avoid detecting echoes from a click or to prevent detecting a large number of clicks if an animal is buzzing near the recorder. Store Snippets: Select to enable storage of detection snippets. -

interval, they will be reported in the BCL file (see below) but no snippet will be saved. This puts an upper limit on the memory usage rate making it easier to calculate for how long the SoundTrap will be able to record. •... - Page 27 While every care has been taken in producing the SoundTrap Click Detector, this is free software offered ‘as is’, in the hope that it will be useful: there is no warranty, implied or otherwise, nor implication of fitness for any particular purpose. Please use responsibly! Test that the code functions correctly on your SoundTrap before deploying it, e.g., by setting the RDT to 12 dB and then tapping lightly on the hydrophone with a finger nail.
