A New Generation of Wildlife Tags

Pop-off Satellite Tags for better science

 SeaTag is about enabling innovative research at a favourable cost that supports studies at a realistic scale. Everything about these tags is designed to squeeze as much data as possible from a versatile, and robust wildlife tag.  We offer a modular family of tags. All start with fundamental capabilities such as solar power, 360 degree light sensing and kinetic release for sea and freshwater use.  We then adding model specific sensors to support your studies.  From a magnetometer for robust direct-measured migratory tracks, accelerometer for behavioural studies, or introducing this year a spawning detection capability.  While other manufacturers may offer hundreds of tag variants, our modular approach provides the cost savings needed to yield scientific results that are supported by robust sample size.

SeaTag-MOD is fully reusable if recovered.  Get more than one go out of your tags, and as many as four go-arounds reported to date.

Non-Species specific approach

A low-drag, versatile 'glove' compatible with most species. 

Always Innovative

Enabling new insights

Fresh and Salt Water Use

Our kinetic release payload section allows use in any water system. 

 Better Drag Coefficient 

Less drag means better tag retention and compatibility with smaller and faster species.

Effects of pop-up satellite tags on the metabolic rate of juvenile Sandbar Sharks - Scott Lynch  

Transparent, directly-measured migratory tracks.

Other tags estimate tracks based on complex algorithms that yield opaque results which while looking entirely believable can be massively incorrect due to model unknowns.  SeaTag yields entirely transparent and defensible direct-measured positions based on the simple intersection of magnetic field intensity for latitude and robust light measurements for longitude.

Innovations for 2019

Teflon Antenna

Teflon sleeve for better reporting rates and transmissions from partially submerged antenna's. 

Extended Depths

 SeaTag-MOD extended depth version for those deeper diving animals. We cover every part of the ocean.

Spawning Detection

Need to know where and when your study species spawns?  Our new spawning detector payload section for SeaTag-MOD answers this important question. 

Odoo - Sample 1 for three columns


Three SeaTag models designed primarily for Stock Assessment and Mortality studies.  Small, low drag, and with a selection of sensors.  Compatible results across a range of capabilities and price points for the best combination of data return and study sample size.


Odoo - Sample 2 for three columns


Designed for penguins and sea-turtles, this tiny but robust tag offers duration unlimited migratory tracks in a low-cost light-weight Argos satellite tag.  


Odoo - Sample 3 for three columns


A cost-effective and reusable tag built for detailed behavioural studies with several sensors including light, temperature, depth, acceleration and a magnetometer.  New for 2019:  a plug-in payload section to detect spawning of the tagged animal.

Tags which have a functional defect. 


 Desert Star’s SeaTag family of electronic animal tags is the result of a NOAA sponsored SBIR program and acknowledges the two fundamental demands of the agency: boosting innovation in tag design and significantly reducing tag cost.

Prior to SeaTag, pop-up satellite tags cost $4000 each severely limiting their use. SeaTag revolutionized the tagging field by offering stored solar power systems augmented by batteries, functionality for freshwater use, magnetic sensing for reliable position estimation, fouling resistant housings and much lower pricing for much larger sample size.

These advances in the field have created two distinct product lines: S.A.M. tags (Stock Assessment and Mortality Tags) and an advanced studies pop-up satellite tag (SeaTag-MOD).

SeaTag’s strong technological and cost advantages are the result of Desert Star’s broad experience in many underwater technologies and economies of scale provided by our multiple product lines. A modular design approach and a large design library underpin all of our products and allow our creative workforce to learn quickly and design new tag versions efficiently using a ‘cut & paste’ approach. Reliability is thus enhanced as new tags ‘inherit’ the field record of established design blocks.

In addition, all SeaTag devices come with an extended warranty (ST-GOLD) option that covers non-reporting, under-reporting or otherwise non-functional tags during and after their deployment periods. If a tag falls under ones of several categories, Desert Star Systems ships a replacement tag at no additional cost.

SeaTag presents a change in the concept of satellite tagging transitioning from studies using 10 or 20 tags to a systematic method of data collection, retrieval and deployment utilizing a complementing line of pop-up satellite tags. No longer should you deploy a few tags of just one type! Instead, use a targeted collection of SeaTag devices to maximize your data return while minimizing study costs.
