Coastal & Oceans

Share |

Marine water monitoring is required for a number of purposes: the detection of diffuse pollution; to ensure the compliance of construction projects (especially if dredging is involved); for Environmental Impact Assessments and for scientific research. We can provide monitoring solutions from the surface down to 10,000 metres.

SOOGuard Ferrybox

Aanderaa SOOGUARD Environmental Shipborne Data Collection System

The Aanderaa SOOGUARD FerryBox system provides environmental water quality monitoring from ships of opportunity using Aanderaa Smart Sensors and the SmartGuard data logger. The system is designed specifically to offer a low maintenance, low operating cost system while providing high quality data.


RCM Blue Doppler Current Meter

Aanderaa RCM Blue Current Meter

The Aanderaa RCM Blue is a self contained single point Doppler current meter with Bluetooth for communications and data retrieval. With a large battery and memory capacity, the instrument can be deployed for in excess of one year.


YSI Pro 1030 meter

YSI Pro 1030 - pH / Conductivity / Salinity / Temperature Meter

The Pro 1030 is the latest in the family of the YSI Professional Series. Measuring temperature, conductivity, pH and salinity with cable lengths up to 30m, this rugged meter is ideal for field monitoring programmes


Radar level

H-3611/H-3612/H-3613 SDI-12 Radar Water Level Sensors

The WaterLOG® H-3600 series radars are a family of SDI-12 water level sensors. Typical applications include non-contact measurement of river, lake and reservoir water level. The H-3611/3612/3613 radars are easy to use and interface with any data recorder/logger that is SDI-12 compliant. The sensors measure Stage in units of Feet, Metres or other engineering units.



YSI PeliNet Portable Telemetry

PeliNet is a portable, instantly deployable, telemetry solution for short term and emergency monitoring applications. PeliNet is based on YSI's Econet system allowing the user to make instant, meaningful decisions without the need for additional costly resources or time-consuming trips to the field.


Harbour Buoy illustration.

YSI Harbour Buoy Platform - EMM68

Small buoy for easy access to water quality data. Quickly deployed environmental monitoring buoy with telemetry and data acquisition electronics.  This buoy is ideal for project-based deployments; it simplifies installation by eliminating the need for a crane, divers and large service equipment.



YSI EMM700 Data Buoy Platform

The EMM700 buoy is a medium-sized platform suitable for near-shore and inland water applications.  It is designed around logging, sensors, and remote telemetry.  The bay buoy platform will deliver data for years, making it suitable for research and long-term monitoring applications.


Antifouling technology developments include copper mesh screens, tape and sensor bodies.

YSI Anti-Fouling Kits

YSI's Anti-fouling Kits, designed for 6-Series Sondes, are reliable and affordable ways to significantly lengthen deployment times, reduce operating costs, and ensure high-quality data for continuously deployed monitoring systems.



Photosynthetically Active Radiation (PAR)

PAR measures irradiance -- the amount of sunlight or ambient light that diffuses through water compared to surface light, PAR focuses on the dynamics of the photic zone, typically 1 - 5 meters below the surface and leads to an understanding of photosynthesis, toxic algae blooms and eutrophication (nutrient loading)


650MDS - Multiparameter Display System

YSI 650MDS Data Display / Logger

The YSI 650 is a field rugged display / datalogger capable of communicating with any YSI 6-Series multiparameter instrument


Argonaut MD
