The Profiler II offers researchers the unique opportunity to use this system as a free fall profiling device or in conjunction with a detachable float for near-surface measurements (HyperTSRB). The Profiler II is designed to interchange Satlantic’s hyperspectral or multispectral optical sensors making this system the most versatile platform for measuring the apparent optical properties of the ocean.

The Profiler II system comes complete with a molded flotation collar that is easily mounted to the profiling frame for real time, near-surface measurements. Upwelling radiance and irradiance measurements can be collected as close as 5 cm from the sea surface.

The optional integration of Wet Labs ECO series sensors offers a new combination for concurrent determination of chlorophyll fluorescence and optical backscattering in either profiling or surface mode.

Our Surface Acquisition Systems (SAS) are designed for above-water measurements of ocean colour using Satlantic's multispectral or hyperspectral digital optical sensors. The system consists of two radiance sensors and one irradiance sensor. The main advantage of the MicroSAS system is it's small size and extremely fast sampling rate. Special adapters can also be mounted to the MicroSAS radiometer to narrow the field of view to a half angle of 1.5º to 0.75º. The HyperOCR SAS radiance sensors are designed with a narrow field of view compared to the in-water version and provide 136 channels of Li and Lt data.

The SAS can be mounted on a variety of vessels to provide continuous monitoring of ocean colour along the ship's track, on towers or other platforms to provide time series observations, or the system can be used for airborne remote sensing of ocean colour.


Applications:

• Estimate concentrations of dissolved organic matter, suspended sediments, and chlorophyll
• Bio-optical algorithm development and modelling
• Satellite calibration and validation
• Environmental monitoring
• Data products include water leaving irradiance, remote sensing reflectance, and energy fluxes

Features:

• Precision measurements of Li, Lt & Es
• Adjustable viewing angles from Nadir to Zenith
• Multiple radiometer options - multi, hyperspectral or combinations
• Full ancillary suite - tilts, sea-surface temperature, GPS
• Data logging and processing software included

The Bioshutter II is an autonomous underwater shutter attachment designed for use with Satlantic radiometers. The primary purpose of the shutter is to prevent marine bio-fouling of the sensor optics in moored, time-series applications. Copper, and copper-based alloys have long been known to have good resistance against bio fouling and have been used in a diverse variety of commercial applications. Scientists working at the University of California Santa Barbara Ocean Physics Lab under the auspices of the National Ocean Partnership Programs’ (NOPP) Ocean-Systems for Chemical, Optical, and Physical Experiments (O-SCOPE) project developed an underwater shutter device for use with instruments such as Satlantic’s OCR-500 and HyperOCR series instruments. The Satlantic Bioshutter II device builds upon the success of this instrument by combining an innovative copper shutter and an input power controlled motor drive assembly to ensure robust operation in harsh marine environments.

Features:

• Restricts marine growth on sensor optics in moored applications
• Robust mechanical design  
• Completely autonomous - only external power required
• Simple operation – opens when power is applied, closes when power is removed 
•  Fast operation – 4 seconds to open, 6 seconds to close (typical)  
• Low current consumption (1 mAh to open shutter; 0.16 W thereafter)  
• User-selectable 180 degree (default) or 90 degree shutter movement

The SAT-THS (Satlantic Tilt-Heading Sensor) is an advanced pitch/roll compensated compass/magnetometer system. The instrument is well suited for numerous oceanographic applications requiring precision orientation, navigation and leveling information.

The SAT-THS gives the user a continuous 360-degree azimuth heading, combined with angular directional tilts from the horizontal plane. The SAT-THS is compatible with SATNet, Satlantic’s proprietary instrument networking protocol. Telemetry can be obtained by PC-based acquisition software such as SatView, or by embedded systems such as DacNet. 

Features:

• Monitor mooring direction and orientation
• Track surface buoy movements
• Record ship movements to compliment primary instrument data

Satlantic’s ISUS V3 nitrate sensor is a real time, chemical free sensor designed to overcome the traditional challenges associated with reagent-based nitrate analysis in aquatic environments. The ISUS technology uses advanced UV absorption technology to provide accurate nitrate concentration measurements in real-time.

Applications:

• Long term nitrate monitoring
• Water quality assessment in estuaries and coastal environments
• Freshwater nutrient loading studies
• Watershed TMDL assessment
• Phytoplankton bloom prediction
• Wastewater monitoring

The MBARI-ISUS technology was developed by Dr. Kenneth Johnson  and Mr. Luke Coletti of the Monterey Bay Aquarium Research Institute and published as Johnson and Coletti 2002, In situ ulrtaviolet spectrophotometry for high resolution and long-term monitoring of nitrate, bromide and bisulfide in the Ocean.

The new ISUS V3 now comes with full speed USB capability and the ISUSCom windows-based software package.  ISUSCom allows users to log and view real time data, download files, set sampling schedules, and much more all through an easy to use interface. (MBARI).

The ISUS-X is a combination of the Satlantic's chemical-free ISUS nitrate sensor with the STOR-X data logger system. The ISUS is a robust, proven technology that provides real time in-situ nitrate concentration measurements using chemical-free UV absorption technology. ISUS has been field proven in a wide range of challenging conditions and is available with an effective biofouling probe cover for moored applications. In mooring mode, the ISUS-X provides power, sensor and telemetry control as well as data processing and storage.

Capabilities:

• Provides chemical-free Nitrate concentrations using UV absorption technology
• Provides input data/power ports for up to 5 sensors
• Provides user interface to set and modify data collection schedule
• Combines all sensor data into data packets
• Data packets are in engineering units and time/date stamped for accurate correlation of data
• Data packets can be stored internally on a 256 MB flash drive and/or transmitted via GSM modem
• Commands can be sent to the ISUS X to change scheduling and to trigger sensors to collect data (water sampler control for example).
• The ISUS sensor retro probe is protected with a specially designed copper/nitex shield to reduce fouling during long term deployments
