fluorometer integration

Introducing C3/VideoRay ROV Integration Kit
The C3 Submersible Fluorometer is now available for integration with the VideoRay Pro 4 Submersible Remotely Operated Vehicle (ROV).  In response to a growing demand for rapid water quality and oil pollution measurements using highly portable and adaptable methods, VideoRay developed an integration kit which mounts the C3 directly below a submersible camera installed on the ROV. C3 data are stored internally, streamed real-time to a terminal window, and recorded to a file using VideoRay’s topside computer.  Those C3 data are time-stamped and include depth and temperature measurements.  Using the time-stamp, C3 data can be cross-referenced to the VideoRay video if the VideoRay’s text overlay is enabled and the video is recorded.  Those data can also be geo-referenced with positioning system data from optional position tracking systems. For more information please view frequently asked questions.


Instruments In Action

Washington State Department of Ecology’s Environmental Use of the Turner Designs C3 Submersible Fluorometer to Assess Water Quality and Validate Satellite Data
The marine waters of Washington, namely Puget Sound, are an important resource for people living in Western Washington.  Toxins, bacteria, eutrophication, and an increasing population are all factors of great concern currently affecting water quality. The Washington State Department of Ecology (WaECY) recognized the importance of monitoring water quality and implemented an impressive system of monitoring, data collection, validation and distribution of information.  On May14th 2010, as part of its Marine Water Quality Monitoring Program, WaECY deployed the Turner Designs C3 Submersible Fluorometer in a seachest system installed onboard the Victoria Clipper IV (Clipper Navigation, Inc). The Victoria Clipper IV is a vessel of opportunity that travels daily between Seattle, Washington and Victoria, British Columbia. The C3 is part of a larger program implemented by WaECY that provides reliable water quality data on a wide-range of scales (present and historic). Sensors onboard the Victoria Clipper IV are controlled using a rugged Dell laptop running Windows XP.  Standard Serial-to-USB cables are used to achieve simultaneous communication with four RS-232 enabled devices.  The laptop is configured with RS-232 data logging software (using Advanced Serial Data Logger) which parses the incoming data and saves the standard ASCII output to text files.  Daily data files from the C3 Fluorometer and a Garmin 17x HVS GPS are stored separately and compressed each evening to minimize bandwidth usage during data transfer.  These data files are later merged during post-processing.

Fluorometer installation area

Turner Designs’ C3 Fluorometer is installed into the Clipper’s port-side seachest using a custom fabricated seachest cover designed by Pacific Fisherman Shipyard and Electric, LLC.  WaECY anticipates the installation of a Citadel TS-NH thermosalinograph into the Clipper’s starboard-side seachest to be completed by mid-March 2011.  Sensors are cleaned and serviced on-board every 6 weeks and additional field samples are collected monthly by WaECY’s marine flight sampling program along the Clipper’s Seattle-Victoria transect.

The C3 installed onboard the Victoria Clipper IV is configured to collect chlorophyll fluorescence, CDOM fluorescence, turbidity, and temperature data. The fluorometer data are used in conjunction with data from various satellites such as the European Space Agency’s MERIS satellite. The primary objective of MERIS is to observe ocean color, both in the open ocean and coastal zones. These observations are used to derive estimates of chlorophyll concentration and suspended sediments. The C3 provides validating data for both the satellite products and WaECY’s other continuous marine monitoring efforts.
fluorometer fluorometer The Washington State Department of Ecology recognizes that the monitoring capabilities of the C3 fill a valuable gap in public service marine water quality monitoring. WaECY anticipates distributing near-real-time and quality controlled data via their website. This website is currently undergoing a major upgrade, in part to accommodate this new Clipper dataset, but also to highlight and distribute some newly developed information products (some of which illustrate the benefits of collecting daily optical data from the Victoria Clipper IV for general environmental monitoring applications and satellite product validation).  They are also exploring the possibility of displaying real-time data to the Clipper’s passengers using an on-board kiosk.


Clipper transect data from 13 June 2010.  Chlorophyll a fluorescence gives an estimate of algal biomass.  Warm colors show larger concentrations.  High algal concentrations extended throughout Whidbey Basin and in Puget Sound as far north as Marrowstone Is.  Lower algal concentrations were found in the Strait of Juan de Fuca.

Turner Designs would like to thank the Washington State Department of Ecology and Dr. Brandon Sackmann for information contained in this article.


New Products and Accessories

DataBank USB Cable
The DataBank Handheld Datalogger now comes standard with a USB communications cable eliminating the need for a separate RS-232 to USB converter.  Customers who prefer an RS-232 cable connection can still order an RS-232 cable by referencing part number 021-2900. 

Cyclops-7 Submersible Fluorometer now available in Plastic
Our C-7 Submersible Fluorometer is now available in a corrosion-resistant plastic housing. The plastic housing is ideal for long term deployments or environments that may degrade or corrode stainless steel sensors. The new plastic body offers the best option in corrosion-resistant material without incurring the higher costs of titanium housings. The plastic C-7 is available with either standard connectors or, for greater corrosion resistance, titanium connectors. The plastic C-7 is available in all the same optical configurations - Chlorophyll, Rhodamine WT dye, Fluorescein dye, Phycocyanin, Phycoerythrin, CDOM, Optical Brighteners, Crude Oil, Refined Fuels, and Turbidity.


New Technical Support Specialist
Introducing Kathleen Henderson
We recently hired a new Technical Support Specialist, Kathleen Henderson. Kathleen came to us from the U.S. Geological Survey where she was a wildlife biologist working out of the Don Edwards San Francisco Bay National Wildlife Refuge in Fremont, California. Kathleen supervised field operations on a large scale and diverse monitoring program for the South Bay Salt Pond Restoration Project. She is experienced in field applications focused on water quality analysis as well as ecological monitoring.  Her strong points are follow-through and coming up with creative solutions to problems. We are continuously trying to add talent and expertise from the field that will add to our diverse research and development team. We are excited to have Kathleen on board!

Tech Corner

Detecting Algal DOM Using the Cyclops-7 Refined Fuels Sensor
The Cyclops-7 Refined Fuels sensor, developed and released in the summer of 2010, is mostly used to detect Refined Fuels in water. This Cyclops-7 uses deep UV excitation wavelengths (
Recent tests have shown that the Cyclops-7 Refined Fuels sensor will also detect fluorescence from algal or plant dissolved organic materials (Algal DOM).  In the plot below, two lab standards were analyzed using a Cyclops-7 Refined Fuels sensor.  Naphthalene disulfonic acid (in blue) is used as a proxy for refined fuel.  Tryptophan (in red) represents one type of Algal DOM.  The fluorometric response for both standards is nearly identical indicating that the Cyclops-7 Refined Fuels sensor can be used to detect an Algal DOM component of natural water samples. 

graph1 To test the response of actual plant DOM, we soaked rice plant in water for a period of 3 days, allowing the plant to release DOM into the water to be analyzed using Cyclops-7 Refined Fuels sensor.  Serial dilutions were made from the 100% leachate solution to generate a response curve.  The plot below shows how the Cyclops-7 Refined Fuels sensor responds to rice leachate. 

Algal or plant DOM is an important parameter for determining algal or macro-algal contributions to DOM pools for researchers looking at impacts, distribution, and cycling of DOM in aquatic systems.  The qualitative data obtained from this Cyclops-7 sensor can be used to rapidly pinpoint areas of interest that require a higher degree of analytical measurements, saving researchers time and money.

DataBank Software and Firmware Version 3.06 Upgrade Now Available
Turner Designs suggests all DataBank users upgrade DataBank software and firmware from version 3.05 to version 3.06, which can be downloaded from Turner Designs’ website at

This upgrade allows users to connect to and communicate with the DataBank at a faster rate.  We’ve also modified the DataBank’s data string to include the gain or range for each sample measured. 

New C3/C6 Firmware Upgrade
The C3 Submersible Fluorometer and C6 Multi-Sensor Platform are versatile in situ instruments that can be configured for real-time data output which is important for monitoring protocols, fluorophore mapping, and integrating with other instrumentation. The current firmware version 2.1 does not allow real-time data output to continue when the instrument’s memory is full. We revised the current firmware and released version 2.2 allowing users to continue capturing real-time data output even when the memory’s maximum capacity is reached. We recommend all C3 and C6 users to upgrade to firmware version 2.2 enabling this feature and keeping up to date with the latest functions available.

Note: Upgrade is not required for customers using the C3 for the SMART protocol.
