The effects on phytoplankton from UV treatment systems is an area of concern as some methods may run into problems when trying to accurately estimate cell counts after UV treatment.  A detailed study by Bradie et al in Journal of Sea Research (2018) explored how well rapid indicative tools can estimate cell counts compared to microscopic analysis for the purpose of estimating phytoplankton cells after UV treatments in actual ballast water samples.  Results using the Ballast-Check 2 showed a very good correlation with microscopic analysis indicating the Ballast-Check 2 does a good job at estimating cell counts in UV treated ballast water samples.

In 2017 the Department of Land and Natural Resources (Division of Aquatic Resources), headed by Julie Kuo, finished testing a Ballast-Check 2 Handheld Fluorometer which is used for rapidly indicating if ballast water is within compliance levels set by D2 discharge standards. Results showed that the Ballast-Check 2, optimized for lower phytoplankton concentrations typically associated with ballast water, can rapidly and reliably measure 10-50 micron sized phytoplankton helping authorities quickly decide how to proceed with managing de-ballasting events for ships at port.

Turner Designs recently developed new data reporting software which ensures data integrity as requested by Saudi Aramco.  The new software writes Ballast-Check™ 2 results directly to a PDF report which cannot be altered.  Saudi Aramco is now able to ramp up their use of indicative compliance tools for collecting data from arriving ships. This data reporting software is included with all new Ballast-Check 2s and is available as a download for previously purchased units.

Ballast-Check 2 evaluates RISK of non-compliance for the D2 regulation using estimates of cell counts and cell viability as independent parameters during ballast water analysis.  This evaluation method has been repeatedly proven to give accurate risk assessments for all treatment types, including UV.

Ballast-Check 2 is a small, lightweight, highly durable handheld fluorometer ideal for quick indicative compliance checks of ballast water. Factory-set, Ballast-Check 2 is ready for use right out of the box, no calibration necessary. Extremely simple one-button measurements display estimates in less than 1 minute of both algal abundance and algal activity, providing ship crew or port state control with an indication of risk for exceedance of the regulation. Small, battery-powered, water-proof, and easy to use, Ballast-Check 2 is perfect for field use. Ballast-Check 2 is ideal for quick on-the-spot assessments of the effectiveness of a ballast water treatment system.

Turner Designs’ Databank Handheld Datalogger is upgraded to include an internal GPS chipset allowing users to log GPS coordinates along with measurement data for location tracking.  Using GPS & GLONASS Global Navigation Satellite System, DataBank provides horizontal position accuracy of 2.5 meters.  DataBank stores up to 9,999 records as well as 16 calibrations and uses an intuitive GUI interface for configuring and calibrating Cyclops sensors; logged data are downloaded via USB.  DataBank’s internal rechargeable battery provides continuous measurements up to 15 hours or continuous GPS data collection up to 5 hours.

Databank comes with one factory-installed cable that supplies power to and communicates with Turner Designs’ Cyclops sensors.  Standard Cyclops sensors are available for detecting: in vivo Chlorophyll, Crude Oil, Refined Fuels, CDOM/FDOM (dissolved organic material), Blue/Green Algae, Fluorescein Dye, Rhodamine Dye, PTSA Dye, Optical Brighteners, Tryptophan, and Turbidity.  Cyclops sensors can also be configured with custom optics for specialized applications per customer request.

Integrated GPS data are important for field work such as conducting dye trace studies, mapping algal blooms, or looking for the presence of optical brighteners as an indicator of wastewater contamination.  Small and lightweight, DataBank is ideal for such remote field work.

Following detailed scientific and technical evaluation by the Environmental Protection Department of Saudi Aramco, the Turner Designs’ Ballast-Check 2 Handheld PAM Fluorometer (USA) is approved as a valid Ballast Water Sampling Instrument.  Saudi Aramco will now accept results from certified technicians using Turner Designs Ballast-Check 2 Handheld PAM Fluorometer in addition to the other previously approved instrumentation.   Saudi Aramco announced in August that all ships calling at its ports and terminals are required to provide ballast water test results to show compliance with the IMO BWM 2004 convention.  It has been a challenge to sample all the arriving ships and Saudi Aramco looks forward to having additional certified technicians and instrumentation performing the tests.

Turner Designs is working closely with several service providers to train and certify them to support Saudi Aramco as more are needed.  Turner Designs is partnered with Wilhelmsen Ships Services to provide worldwide sales and support of Ballast-Check 2 to ship owners and operators.

Environmental conditions are changing leading to significant shifts in algal populations. An example of this is the noticeable worldwide increase in Harmful Algal Blooms, primarily cyanobacteria. Identifying algal groups within a total phytoplankton population is critical as some groups can be toxic, affecting public health and economies. Turner Designs is excited to introduce products facilitating increased understanding of the composition of algae populations.

PhytoFind provides in situ algal classification distinguishing among algal groups using specific fluorescence signatures. Real-time abundance estimates are calculated for PE-containing algae (mixed group), PC-containing algae (Cyanophyceae), and total algae (all other algal groups). Calculations include an automatic correction for interference from dissolved organic materials (DOM) providing more accurate real-time estimates. Optics are optimized to minimize interference from turbidity.  Abundances are displayed and logged as group percentages along with temperature, depth, and accurate chlorophyll (µg/L) concentrations.

PhytoFind’s durable Delrin housing is highly resistant to harsh environments. Additional antifouling materials such as wipers and copper plates can be included to minimize biofouling for long term deployments.  If deploying long-term, a high capacity external submersible battery with an estimated maximum deployment time of three months is available.  All PhytoFinds have a large capacity for internal memory storage (over 60,000 data lines).

PhytoFind is factory-calibrated; no calibration standards or tools are required.  Solid state optoelectronics ensure long term instrument stability.  Solid reference standards are available for users wanting to confirm stability in the calibration.
