The Sonotronics EMT-AR “Accelerometer Transmitter” is designed to provide information pertaining to movement of any animal or target tagged with the transmitter. The EMT-AR contains an onboard 2 dimensional accelerometer. When movement (acceleration) is detected on either axis, the quantity and direction of the acceleration is processed and one of many different possible output algorithms are utilized. EMT-AR ACCELEROMETER BASED ACOUSTIC TRANSMITTER Sonotronics EMT-AR (Angle Reporting) transmitters use an integrated accelerometer to measure and transmit the tilt angle or inclination of attached equipment, enabling real-time monitoring of its orientation. A surface receiver can be used to verify the alignment of instruments such as ADCPs without requiring a diver. With operating lifetimes of up to four years, these transmitters can also mark deployment sites for future relocation. Monitoring is performed using either the USR-23 deck receiver or the UDR diver receiver. Links: EMT-AR Datasheet EMT-AR Manual VIDEOS PRICES

The DH-4 provides the greatest range and precision in locating transmitters from 30kHz to 100kHz. The parabolic reflector provide 16db of gain over a comparable omnidirectional hydrophone, and yields a calculated DI of nearly 25db, reducing the effect of environmental noise. The DH-4 is the primary hydrophone for manual/active tracking. MODEL DH-4 DIRECTIONAL HYDROPHONE The DH-4 provides the greatest range and precision in locating transmitters from 30kHz to 100kHz.

Hydrophones Each hydrophone type has characteristics suited to different tracking needs. Directional hydrophones provide the longest detection ranges and can give an accurate bearing to a transmitter, but their larger, non-hydrodynamic design generally requires the boat to be stopped during use. Towed hydrophones are easier to deploy and can be used from a boat moving at trolling speeds, but they are more susceptible to noise from all directions and do not provide a bearing to the transmitter. For tracking over large surface areas, using both types is often the most effective approach.

Eyelets allow attachment of small weights or diving lures to ensure the hydrophone is kept at depth while trolling. This design, though simple, rivals more elaborate and expensive systems in actual field trials.

The ETN, together with industry (being Thelma Biotel, Sonotronics, and Lotek), have worked on the development of new open tag protocols, which are available for all telemetry users across the world. As stated in the compatibility note , it is now clear that encrypted protocols in acoustic telemetry should be avoided by all means. To move forward towards a much-needed pan-European collaborative network that could provide relevant information in support of decision-making processes related to conservation and management, compatibility between brands and agreements on transmission protocols and ID allocation are imperative. Therefore, the ETN, together with industry (being Thelma Biotel, Sonotronics, and Lotek), have worked on the development of new open tag protocols, which are available for all telemetry users across the world - this technology is NOT restricted to Europe. This resulted in two robust and energy-efficient transmission protocols aimed for the aquatic research community, being OPi and OPs, for ID and sensor tags respectively. The Open Protocol: OPi supports over 1 million unique IDs, while OPs supports over 64 000 unique IDs with up to 4096 data points resolution. Both protocols are short and effective to reduce issues with transmission collisions. The protocols are available for all interested manufacturers after agreeing with the terms of references. Opening the infrastructure networks of acoustic telemetry to all manufacturers of different types of sensors and tags will drive innovation, and boost availability of new solutions for future research. The Manufacturers handed over OP to the ETN, who assigned the Flanders Marine institute as a third party to control the ID allocation related to these protocols.

Acoustic telemetry resources, papers, and information on how to choose transmitters for your study. Resources Depth or Temperature Telemetry Product Comparison A datasheet which shows the comparison of Sonotronics products associated with Depth and Temperature Telemetry Understanding Sonotronics Unique Pinger ID Algorithm A document which explains the algorithm used by Sonotronics for the unique ID of transmitters. Custom transmitter labels Email us to customize the labels in your transmitters. This allows you to leave a visible message that shows through the clear wall of the transmitter telling anglers, etc. where they can send the transmitters if found How to choose transmitters for your study Consider the following when choosing the appropriate transmitter. Size – The commonly used rule is 1.5% – 2% of the animal weight in air is maximum allowable transmitter weight in water . Exceptions to this rule are sometimes made by biologists in the case of robust species, crustaceans, and other animals that are determined to be able to hold a larger transmitter. Lifetime – It is recommended that a lifetime that is 125% of the actual length of the study is used. This allows extra room at the end of the study, and helps guarantee a high output from the transmitters throughout the study. Range – It is recommended that the highest output transmitter available that fits in the necessary lifetime and size categories be used. This guarantees greatest ranges in both automatic and manual tracking. Keep in mind that a number of factors in the environment can limit range. Telemetry – There are a number of telemetry options available on Sonotronics transmitters. Temperature, acceleration (used for feeding and mortality), depth, and tilt. These options are chosen based upon the data desired in the study. The Don L. Brumbaugh Memorial Equipment Scholarship The Sonotronics’ Equipment Scholarship, established in 2005, commemorates Donald L. Brumbaugh’s pioneering work in the development of fisheries and wildlife biotelemetry technologies. The scholarship is designed to aid students in fisheries research projects. Read more…
