Introduction
fluorometer
Introducing several new products last year is making this year particularly busy for everyone at Turner Designs.  Our C-sense pCO2 sensor is getting a great reception from customers while our partners expand options for integration. Our red chlorophyll sensor is deployed at several sites and we should have good data sets to share soon. Ballast-Check 2, our Handheld PAM Fluorometer, will soon be with ACT & USCG for validation testing as a ballast water compliance monitoring tool. This instrument will be critical for verifying compliance when the regulations go into effect. ICAM, our new in situ absorption meter, has been in the field on local oceanographic cruises collecting valuable data. And better than OUR news is YOUR news – many thanks for sending in articles about how you’re using our instruments. We always love seeing our “instruments in action.”

Submersible logger for C-sense pCO2 sensor

Precision Measurement Engineering, Inc. (PME), Turner Designs’ partner who developed the Cyclops-7 Logger, is proud to announce the release of the C-sense Logger, a submersible, portable device that records time, date, internal temperature, and voltages from the C-sense.
C-sense enables pCO2 monitoring over an extended period of time in water, oil, or water and oil mixtures to a depth of 600m. Applications include water quality monitoring, aquaculture, wastewater monitoring, reef monitoring, carbon capture storage monitoring and biofuel production.
Integration with the C-sense Logger enables collection and internal storage of data at a variety of sampling rates set by the customer. Data are offloaded to a computer via a USB cable for easy viewing and analysis. The logger and sensor are powered by the Turner Designs re-chargeable battery pack, potentially powering the C-sense Logger to collect 3,000 samples.

Profiling in situ Absorption in the Monterey Bay with the ICAM
On October 7th 2014, Turner Designs’ Product Specialist Luke Beatman participated in a research cruise on Monterey Bay with the cooperation of Raphael Kudela’s Biological Oceanography Laboratory at UCSC. The intentions of the cruise were to characterize resident phytoplankton populations and make determinations as to how they are affected by the dynamics of Monterey Bay. Cruises such as this one often visit historical ocean stations to monitor how conditions have changed over time with respect to biological variables such as chlorophyll a concentration and the relationship to physical variables such as salinity and temperature. On this cruise, 3 stations were visited with the expectations of encountering significantly different oceanographic environments. At each station, the ICAM was cast down the wire of the R/V John H. Martin to a depth of 50 meters. >>read more

MBARI Engineers Integrate Turner Designs’ Rhodamine Cyclops into Autonomous Vehicles
fluorometer
Monterey Bay is a dynamic oceanographic environment that offers scientists from around the world unlimited opportunities to study the interactions of marine organisms with their surroundings. The Monterey Bay Aquarium Research Institute (MBARI) coordinates and sponsors multi-institutional experiments in a project named CANON (Controlled, Agile, and Novel Observing Network). The main focus of CANON is to understand how microbial communities react to continuously changing physical and chemical conditions. CANON researchers use a wide variety of observations from satellite and airborne sensors, autonomous surface vessels, autonomous underwater vehicles, gliders, drifters, research ships, and moorings. For the most recent field campaign, the scientists were focused on remineralization of organic matter and its environmental controls. A technique valuable to this type of observational science is the use of a tracer, whose evolving distribution provides information about lateral and vertical mixing. This experiment employed fluorescent rhodamine dye as the tracer. In order to track the spatial distribution of the evolving dye patch, MBARI engineers integrated Turner Designs’ Cyclops 7 rhodamine fluorometers into 3 of their vehicles, one ASV and two AUV’s. In the photos below you can see the Cyclops-7 rhodamine fluorometers mounted on the nose of the Tethys AUV and another peeking through the shell of the Dorado AUV. >>read more

Cyanobacteria Research at Southwest Virginia Governor's School

fluorometer
The Southwest Virginia Governor's School (SWVGS) in Pulaski, Virginia recently hosted an annual science fair for gifted high school students. Two SWVGS students, Brandi and Elliott, conducted independent research projects on cyanobacteria using a Cyclops-7 Submersible Fluorometer from Turner Designs. Brandi, a senior, collected phycocyanin data at a recently rerouted stream, a salient part of the local ecosystem and neighborhood community. Brandi intends to make suggestions to Public Works on how to implement a phytoremediation system this summer if cyanobacteria levels are high during the winter months. By averaging multiple readings and running a one sample T-Test, she provided evidence that there was not a significant level of cyanobacteria in the stream above 6 ppb. She recommends that other researchers continue this work to monitor the stream this upcoming summer. >>read more

Benchtop Fluorometry of Phycocyanin as a Rapid Approach for Estimating Cyanobacterial Biovolume
fluorometer
Turner Designs’ Trilogy Fluorometer can efficiently and accurately quantify cyanobacterial biovolume, which has long been considered a major problem for water resource managers plagued with harmful algal blooms. Using a simple extraction process, cyanobacterial abundance can be dependably estimated from measurements of the pigment, phycocyanin, the same day as sample collection. In this way rapid responses to potential water quality threats posed by cyanobacteria are possible.
A link to the abstract can be found here.

Residential Continuous Turbidity Monitoring
fluorometer
fluorometer
While water is the world’s most valuable resource, it is slated to be the scarcest in the years ahead. Faced with increasing demands of a growing global population, dramatic non-revenue water (NRW) losses from aging infrastructure and threats to public health and safety via system contamination, water utilities and regulatory bodies must efficiently manage their operations. >>Read full case study (pdf)

Fondriest successfully integrated C-sense pCO2 sensor
Fondriest Environmental from Fairborn, Ohio recently integrated our C-sense pCO2 sensor into their monitoring station and is now offering it as part of their portfolio. Fondriest included it in their fantastic Environmental Monitor newsletter.  For more information This e-mail address is being protected from spambots.

RBR successfully integrated C-sense pCO2 sensor
fluorometer
RBR from Ontario, Canada also recently integrated our C-sense pCO2 sensor and now offers it as a standard sensor option with many of their underwater data loggers (excluding the RBRsolo and RBRduet series). 
For long term stationary deployments with sampling intervals of 3 minutes or less, the warm-up time of the C-sense dictates that the instrument be powered continuously. In this situation, RBR recommends that the logger be externally powered to account for the additional power required. For more information, This e-mail address is being protected from spambots.

Kentucky University Tryptophan Cyclops-7 Sensor

In August of 2014 we awarded the loan of a Tryptophan Cyclops-7 Sensor to Eastern Kentucky University via our Donation Program. The awarded instrument is being used with a DataBank Handheld Datalogger to determine if E. coli results can be obtained faster using fluorometry. Some field photos are available here. Their work continues so stay tuned for more.

Q&A
fluorometer
One of the most common questions we receive is: What volume do your instruments measure? With some of our instruments, such as the Trilogy, 10AU and AquaFluor, the volume is determined/limited by the cuvette or test tube size. In the case of very high concentrations you will get an “OVER” error message on these instruments, meaning you have saturated the sensor and are outside the detectable range. In this case you need to dilute your samples and do the appropriate calculations to correct the concentration of your sample. With our Cyclops sensors, including the C3 and C6, the answer is a little more difficult to define.  >>read more
