ASTRIIS to assist the studying of large fish and cetaceans with non-invasive underwater device

Although significant improvements in marine data acquisition and processing have been made during the past decades, there is still lack of information and knowledge on in-situ observation infrastructures, as well as on new algorithms built in Earth observation applications retrieved from various platforms. These existing gaps of information about the various marine environments have a negative impact on the sustainable growth of key sectors with high development potential and value creation in the sphere of the blue economy, such as tourism, offshore renewables, and aquaculture along with marine safety.

ASTRIIS is a mobilizing project that intends to mitigate insufficiencies by developing technical and scientific knowledge to conceive and implement a batch of information services and products portfolio emerging from data collected in situ or via remote sensing, combined with forecasting numerical modelling.

The ASTRIIS mission focuses on market needs within the scope of regulation of the maritime space, and on the sustainable exploitation of the oceans and coastal zones. The project also aims to equip society with digital products for training and educational purposes. It is thus intended to contribute to the implementation of the UN 2030 Agenda for Sustainable Development, through the SDG 14 “Life Below Water” and the UN Ocean Decade, by contributing to overcome some of the challenges associated to the protection of the world’s ocean and the boosting of the global blue economy.

A good example of such contributions deals with the ongoing ASTRIIS work on in-situ observations, monitoring and inspection services, which is led by CEiiA. The aim is to develop and manufacture a new generation of in-situ data acquisition systems fostering the sustainability of the ocean in several application areas. The project will thus contribute to further align the blue economy with 5 of the 17 SDGs.

Among these systems are the marine animal tagging devices, which will be equipped with a bunch of sensors capable of recording physiological and biological data as well as live sharing the tag positioning and the corresponding tagged species. These tagging devices, based on a non-invasive and self-recovery concept, will also integrate sensors for blood oxygenation levels and heart-beating measurements to be deployed on fishes and cetaceans.

ASTRIIS is currently working on the mechanical development of the tagging devices, from the materials choice to its manufacturing. During this product development cycle, the ASTRIIS team will be responsible for the following technical areas:

  • Requirements and specifications definition along with partners and end-users
  • Materials choice, rated up to 2000-meter depth
  • Instrumentation definition
  • Mechanical design, from conceptual to detailed designs
  • Weight and buoyancy calculations
  • Hydrostatics and hydrodynamics studies

How can ASTRIIS help improve search and rescue of castaway people at sea?

In a typical search and rescue mission a distress call is made, and a lifeboat is sent to meet the people in distress. The Portuguese Institute for Lifesaving (ISN) has 31 lifeguard stations along the country’s coastline and rescue equipment in about 80 fire brigades. According to this source, in 2020, 985 resources were activated at sea and 613 lives were saved. The question therefore is how to improve the response capacity.

The development of an ASTRIIS search and rescue system has been going on since the beginning of the project. CEiiA and the +ATLANTIC CoLAB joined forces to conduct exhaustive research on buoys and rescue techniques in use, and came to the conclusion that it would be more efficient to develop a system of their own. As a fruit of this collaboration within ASTRIIS and with this goal in mind, a demonstration scenario of the technology and its requirements was defined.

The CEiiA’s autonomous surface vehicle (ASV) type ORCA was chosen as the basis for this activity. The ORCA can reach speeds of 9 km/h and 24h autonomy and operates in coastal regions. It is designed to adapt to the needs of each application, including for now a multibeam sonar, GPS, AIS identification, navigation lights, a 360º camera and a Wi-Fi antenna to be remotely controlled. To meet the ASTRIIS requirements, it will have to accommodate a self-propelled buoy and drop it in a specific location.

In practical terms, a part of the search and rescue mission will have to be ensured by the ASTRIIS platform, which receives the call for help, calculates the estimated operation and rescue times and returns a result (“GO” or “NO GO”) depending on whether there is a reduction of the rescue time compared to the usual procedure. If the decision is to go ahead, the rescue buoy is launched and will reach the castaway at sea shortly after the call for help has been launched on the platform. By being remotely controlled and monitoring its battery levels, we will be able to conclude in real time if this part of the mission was a success or not.




As for the ASV and buoy control, CEiiA is developing a remote control software (ground station). This system will represent an important component for the ASTRIIS project, since it will use prediction models, being able to estimate the displacement of the castaway according to the currents and consequently its position, and calculate the waypoints of the buoy.

The demonstration of the system is planned to take place in Matosinhos in June 2023. Stay tuned to the ASTRIIS website and LinkedIn for further developments on this and other ongoing project activities.
