s Custom Projects
Many of AXYS’ standard products are customized to meet the client’s specific monitoring requirements, however occasionally AXYS gets a request for an altogether new monitoring solution that requires an innovative custom design.
Following a thorough analysis of the project’s monitoring requirements, AXYS will design a system that meets all the criteria. Rigorous project management and quality assurance methodology are followed according to an established process in order to ensure that the final system meets the client’s needs. The AXYS Services team is able to provide training on every system delivered, as well as commissioning and deployment assistance.
Examples of some custom monitoring solutions include:
Wave Energy Testing Instrumentation Buoy
To help Northwest National Marine Renewable Energy Center at Oregon State Univeristy reach their goal of an offshore mobile wave energy testing facility, AXYS partnered with them to design a new buoy – the Ocean Sentinel Instrumentation buoy. AXYS engineers worked with NNMREC staff to develop this custom buoy system that interfaces with numerous custom control and monitoring devices, as well as basic meteorological and oceanographic parameters. The system also provides real time communications that monitor all aspects of the system performance.
Sub-Surface Environmental Monitoring
AXYS has provided sub-surface environmental monitoring systems for a variety of challenging marine environments. With an array of sensors, including temperature, dissolved oxygen, and water chemistry, data can be transmitted to a surface buoy for processing using an acoustic modem or an inductive mooring line. Two-way communication capabilities allow remote system management, including configuration and diagnostics of both the buoy and the mooring components. Sub-surface moorings are easily recovered using acoustic releases, which can be triggered at any time, allowing the instrumentation to float to the top and leaving the anchor on the seabed.
Other examples of custom projects:
- HydroLevel Buoy for NAVOCEANO – portable and flexible GPS buoy for water level measurement
- Arctic Lake Monitoring System – year-round monitoring of arctic lakes using a buoy and sub-surface mooring.
- Water Quality Buoy for Environment Canada – automated water quality data collection.
- WatchMan500 for University of New Hampshire – detect, model and forecast changes in the ecosystem.
s Water Levels and Tides
Monitoring water levels, tides and their currents is an important field of study for many applications, including ship navigation and port operations, government defense, coastal zone engineering projects, ecological studies, and even commercial and recreational fishing.
Traditional tide and water level monitoring uses shore-based tide gauges. The limitations to this method include availability of the land when there are permitting, operational, safety, and security challenges. If onshore tide gauges are not available, a combination of techniques such as tidal constituents databases, tidal zoning and hydrodynamic modling produce estimates of chart datums and tide correctors. This modeling is based on best available information and due to this uncertainty of model input, the water level error can be 40-60% of the total depth solution.
AXYS has developed an electronics payload using DGPS to accurately monitor water elevation in any body of water where a surface following buoy can be deployed. In addition to position measurement, a motion sensor on the buoy measures the pitch, roll and heading of the buoy in real time. This data, along with earth tide corrections are supplied to the buoy’s processor, which performs tilt corrections, averaging and filtering. It enables depth positions to be measured on the absolute three dimensions and eliminates the need to estimate water levels The AXYS HydroLevel™ technology is available on many buoy platforms, enabling the system to be used in differing environmental conditions.

s Ports & Harbours
Accurate environmental data is a crucial part of port and harbour planning and operations. Access to timely and meaningful information can assist decision-makers faced with planning, operations, security, and safety.
An ideal environmental monitoring solution for a Vessel Traffic Management System (VTMS) includes moored buoys, fixed platforms and pier-based installations. Typical sensor configurations provide wind speed, wind direction, waves, current speed, current direction, and water level (tide), all managed by one data management system. AIS messages 8 & 21 are broadcast and met ocean data is transmitted in real time to port operation centers, ship operators, bridge crew, and pilots.
AXYS offers custom, self-contained and fully automated weather and water level systems that can be deployed in key locations to facilitate vessel traffic management operations.
s Offshore Wind Resource Assessment
The need for accurate offshore wind data is growing rapidly worldwide. Wind farm developers and financers understand that accurate wind data is critical to the overall success of the site, not only in assessing the potential power of the location, but also in the positioning of the wind turbines.
The traditional approach for gathering wind data is to construct a meteorological mast equipped with anemometers. However, in the offshore environment this practice is both difficult and expensive to implement. Floating LiDAR technology is an innovative solution to these problems. The AXYS FLiDAR WindSentinel™ buoys use a LiDAR to measure wind at turbine hub-height to provide accurate and reliable data on wind speed, wind direction, and turbulence. Additional sensors can be integrated onto the buoy to achieve a full environmental assessment of the location.
s Metocean Monitoring
Metocean monitoring is an important field of study for many applications including, weather forecasting, climate studies, operations & safety, resource assessment, maritime safety and marine domain awareness, among others.
Typical ocean and coastal monitoring buoys gather data on wind speed and direction, waves, currents, atmospheric pressure, air temperature, water temperature, and relative humidity to measure a variety of meteorological, oceanographic and water quality parameters. Data is acquired, processed, logged and transmitted via radio, cellular, or satellite telemetry to the end user. Many buoys provide the dual function of automated weather station and navigational aid. Deployments can be in various locations, from calm, shallow waterways to 5,000m depths in open ocean. Buoys are typically powered by solar panels and rechargeable batteries, which enable them to remain deployed for long periods of time.
AXYS offers a variety of metocean buoy systems to meet specific monitoring requirements and environmental conditions. Custom mooring design, telemetry communications, and data hosting services are available, as well as commissioning and deployment from our experienced services team.
s Fresh-water and Water Quality Monitoring
AXYS provides customized turnkey solutions for continuous water quality monitoring and fresh-water monitoring projects in large rivers, lakes, and reservoirs.
Continuous water quality monitoring has traditionally been an expensive and complex process. However, with new advances in sensor technologies, such as optical dissolved oxygen sensors and anti-biofouling mechanisms, maintenance requirements are diminishing, thus making continuous monitoring much more attractive and beneficial. Applications for continuous water quality monitoring include environmental assessments for natural resource industries, source drinking water protection, NPDES permit compliance, storm water runoff and sewer overflow monitoring, industrial effluents compliance, stream and habitat studies, water quality research, and total daily maximum loads (TDMLs) monitoring.
Met Ocean Monitoring
AXYS’ buoys are frequently deployed in large rivers, lakes and reservoirs to gather meteorological and oceanographic data, such as wind speed & direction, waves, currents, atmospheric pressure, air temperature, water temperature, and relative humidity. The acquired data can be used for many applications, including weather forecasting, climate studies, operations & safety, resource assessment, and maritime safety, among others.
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.
