s Maritime Domain Awareness

Maritime domain awareness means having timely information about everything on, under, related to, adjacent to, or bordering a sea, ocean or other navigable waterway that could impact security, safety, the economy or the environment. This includes all related activities, infrastructure, people, cargo, vessels, or other means of transport. For marine security, it means being aware of anything in the marine domain that could threaten a country’s national security. And with over 90% of the world’s trade transported by sea, it is more critical than ever to operate secure maritime operations. 

Maritime domain awareness improves marine security by:

  • Quickly identifying actual or potential events
  • Making informed decisions
  • Taking effective action
  • Sharing knowledge with appropriate partners

Arctic Hydrology

There are many hydrological monitoring activities being planned and facilitated in the arctic, motivated by an international need for a better understanding of hydrology in the Polar Regions. Water quality studies are also being undertaken internationally for Arctic lakes and rivers to not only gather baseline data but monitor for natural or anthropogenic transformations to these Arctic aquatic ecosystems.

AXYS is participating in this frontier for Arctic aquatic research by designing and manufacturing remote and automated systems for monitoring hydrometric and water quality parameters in arctic environments. By performing continuous monitoring of these parameters year-round, researchers can use data with unparalleled temporal representation to better understand these dynamic aquatic ecosystems.

 

s Offshore Renewable Energy

Environmental monitoring is a critical factor in the success of an energy capturing device, whether it’s a wind turbine, wave energy converter, or tidal energy converter. Accurate data aids developers in assessing the potential of a location, the positioning of the energy capturing devices, as well as assisting in ongoing operations.

TRIAXYS Directional Wave Buoy

Developers typically work through an initial assessment phase where environmental measurement data is required to pinpoint a location. This data can be acquired from historical sources such as wave watch models, or using in-situ instruments such as wind, wave and current buoys. Buoys provide reliable, highly-accurate, real-time data over a long period of time that allows developers to evaluate the location and make informed decisions about whether to use the site being assessed. The weather data analyzed by oceanographic consultants can be useful in determining if the energy capturing device will stay anchored in place in order to provide long-term energy.

Once the assessment phase is complete and the site has been confirmed, the energy farm is then developed. Given the cost of working in such a harsh environment, accurate environmental weather data is essential to control expenses and protect assets. Knowing the weather in advance from a data buoy transmitting environmental conditions by satellite can save developers time and money during the manufacturing phase.

Once the energy farm is built and in a production stage, it still requires constant monitoring to ensure that the maximum power output is maintained. Monitoring equipment can help developers understand if they are getting the estimated amount of power from their capture device that they were initially expecting.

Environmental monitoring platforms come in a large variety to serve different needs. They also host a wide range of sensors and telemetry devices. Sensors can gather data on winds, waves, currents, atmospheric pressure, air and water temperature, relative humidity and many other parameters.

Types of buoys include, wave and current buoys, meteorological buoys, and wind buoys. As the renewable energy industry begins to develop more offshore resources, it is expected that a significant rise in investment in the ocean monitoring field will occur, with developers relying on these tools to help them improve yields and reduce costs. Environmental monitoring will play a key role in making offshore renewable energy a success in the years to come.
