Seeking partners for a revolution in ocean management
Desert Star's modular line of ocean technology and our business model are breaking the vicious cycle of high costs leading to small markets. Now, we are seeking partners to build a future of comprehensive ocean observation, management and impact mitigation based on affordable, mass deployed smart technology.

W hen University of Miami Professor Neil Hammerschlag tagged a tiger shark in the Bahamas with the rst of a new generation of pop-up archiving satellite tags called SeaTag-MOD in late 2011, the primary purpose of the exper- iment was narrow: to track the migration of the shark. This would be done by tag transmissions to the Argos satellite constellation during brief opportunities when the n-mounted tag broke the surface. In fact, only a few such oppor- tunistic transmissions were received, but internally the tag
scanned and archived sensor readings every 4 min. Timing dawn and dusk via light measurements served as the proxy of the shark’s longitude, and the strengthening or weakening magnetic eld would indicate transitions of latitude. Spurts of acceleration might signal hunting activity, and a pressure sensor along with a temperature sensor would reveal the vertical habitat and temperature preference of the animal.
A year onward, the tag separated from the shark, oated
to the surface and, powered by its solar panels, provided a
continuous stream of position xes and basic status reports
via Argos. Satellite localizing indicated a pop-up position
in the northern Bahamas not far from the tagging location,
with a drift north in the Gulf Stream. The following fall, as
the tiny explorer drifted past Newfoundland, a growing
fuzz of marine fouling dimmed the sunlight reaching its so-
lar panel. Messages and location xes became sparse and
The oceans are among the most important resources of our planet. And while ocean technology is very sophisticated, traditional high cost products, architectures and business models have resulted in low sensor densities. Low sensor densities have left much of what happens in the ocean invisible or uncertain.
At Desert Star, we hear about the consequences of that lack of visibility most every day. The state of some fisheries is poorly known; the risk of a crash clearly present. Navies are struggling to control fishermen turned pirate by the depletion of their resource; as illegal industrial fishing vessels 'go dark' and escape detection. Whales get entangled in growing obstacle courses of pot fishery gear. And, while extraordinary large biomasses have been discovered in the mesopelagic zone, their importance in the ocean food web and function as a carbon sink is poorly understood.
But how could a revolution in ocean sensing be initiated? Twenty-five years ago our young company realized that the key to reducing ocean technology costs dramatically lay in building a broad product line of sensors and systems on the foundation of a single but modular architecture. While demand for any individual sensor type might be moderate, the engineering designs and manufacturing components could be re-arranged and used over and over again, dramatically building economics of scale. Executing on this philosophy, our small company offers a remarkably broad ocean tech product line including satellite reporting tags, acoustic releases, underwater positioning systems, tracking ranges, modems and sound localization capable underwater recorders.
We have introduced products that not only push innovation but are often available at a fraction of comparable devices. For example, our pop-up satellite tags for fish research have now reached a $499 price point, down from competitor's $4000. In response, study sample sizes are going up and the products are enabling new applications, markets and users for whom costs were previously prohibitive or technical capabilities inadequate.. For example, our acoustic releases, a technology previously in the domain of science and large offshore projects, are now improving the business of pot fishermen while reducing the hazard to whales.
This is but a small beginning. A proof of our business concept, and a starting point towards an 'ocean dashboard' that can monitor and interact with our ocean resource in myriad interlinked ways. At the core of such a dashboard will be a small, mass-produced and near universally applicable communicating sensor,the WD-1. Combining elements of our SeaTag-MOD, SonarPoint sound-localizing underwater acoustic recorder, and buoyancy engine technology derived from our ARC-1 acoustic release, this solar powered and small soda bottle sized device will drift with the currents, diving to observe and listen, then surface to report and recharge before submerging again.
Just a few decades ago, microcontrollers, sensors and embedded systems were rare and expensive; or knowledge of everything from the global weather to moisture levels on a particular farmer's field spotty and uncertain. Yet today, it is hard to imagine our world and its responsible management without the myriad of sensors and communicating devices that surround us, monitor our activities, protect our resources and allow us to interact and understand our world in critical detail. While predicting a future ultimately driven by millions of cheap smart sensors deployed from ships or planes in bulk, observing, reporting and ultimately recovered and recycled may appear as a leap of faith now, surely the time will come when the sparse monitoring and poor understanding of this most critical resource today will come to be seen as a reckless and archaic state of affairs. Indeed, our thinking is not isolated. While unique in visualizing very high sensor densities at very low cost and size, it is fundamentally reflected in the thinking of other pioneers such as Liquid Robotics with their concept of the Digital Ocean, or Boeing's recognition of that need as demonstrated by their acquisition of Liquid Robotics and its wave glider.
In time this vision will come to pass, but we also realize that Desert Star is an organization far too small and limited to execute on such a globe spanning scale: Beyond the sensors at sea, implementation of the Ocean Dashboard will require a robust ocean data relay infrastructure,and the AI, back and front end to handle and interpret oceanic data at a massive scale. Thus, in 2017, after 25 years of experimenting and steadily building practical foundations for affordable and scalable ocean technology, we are reaching out to find a large but visionary technology organization with complementary capabilities to jointly take the next steps by implementing regional demonstrators and then global solutions for the most urgent needs in our oceans. While at Desert Star we do not have all the answers, we believe that our extensive line of active products, technology and design database, expertise, industry understanding, business method, reputation and even business advantages such as SBIR phase-3 sole source government purchase rights present an excellent 'tool box' and starting point for Ocean Dashboard. For our partner, this presents a ready opportunity to enter a large, yet specialized and defensible field that is still only lightly contested. One that is supported by a robust ladder of accessible applications starting in our current market and leading through related fields of progressively growing size to ultimately a global ocean information utility of critical importance for the future stability,productivity and security of the oceans.
What could a WD-1 sensor do? This picture sequence shows a SeaTag-MOD first tagged on a tiger shark in late 2011 in the Bahamas (Neil Hammerschlag, RSMAS, U Miami). The tag tracked the shark's migration to Bermuda, New England and back for a year, studying its behavior
. It separated in late 2012, then drifted across the Atlantic for two years (center picture). Arriving in the seas west of Ireland, its data indicated unusual activity. It had 'discovered' the methane seeps of the large and important Porcupine gas field. SeaTag-MOD was designed for the narrow purpose of animal migration tracking, but this episode indicates the capabilities and widespread potential of these tiny autonomous ocean explorers and observers. WD-1 will build on SeaTag-MOD, adding a sound localizing acoustic detector and recorder, a buoyancy engine and more sensor options to arrive at a mass-production device with a universality for ocean sensing not unlike that of the smartphone.
