Millions of gallons of crude oil have now leaked out into the Gulf of Mexico. Everyone is scrambling, working hard to try to contain leaked oil and monitor the areas that are in danger of becoming contaminated. Because oil and water will not mix completely, it's quite easy to see the oil patches or the oil sheen at the surface of the ocean where concentrations are high. But at depths where the oil is trapped by stratification, in areas where the concentration is very low, or when trying to detect the fraction of dissolved oil in water, instrumentation is required.

Turner Designs is doing our part to help clean up the oil spill. We are currently providing many groups with our Ultra Violet (UV) fluorometers specifically designed to detect Crude Oil. Our Cyclops-7 Crude Oil Fluorometer is an analog output device that can be integrated into any datalogger, CTD, or third-party system that is capable of accepting a 0-5 volt signal. It outputs a voltage signal that is proportional to the amount of oil in the water -- the greater the concentration of oil, the larger the voltage output.

The US Coast Guard and other government agencies are currently using our C3 Submersible Fluorometer which houses the Cyclops-7 Crude Oil Fluorometer. The C3 offers real-time data view, data logging, and calibration software. The USCG SMART protocol allows users to obtain a better picture of how oil is horizontally and vertically distributed in water by meshing GPS data with crude oil fluorescence data taken from our C3 Submersible Fluorometer.

Determining how the oil is being moved by currents and tides and its distribution in the water column will greatly help the efforts put forth to try to contain leaked oil and protect the areas that are in danger of becoming contaminated. We're heartbroken at the extent of the damage that is occurring, but find some solace in the thought that we can help in the clean-up. This newsletter is focused on those activities.

Crude Oil Fluorometers

Turner Designs is providing in situ and Laboratory Fluorometers specifically configured to detect Crude Oil for tracking the Gulf Oil spill. Equipment being deployed includes the C3 Submersible Fluorometer as specified in the USCG SMART protocol; the Cyclops-7 Submersible Crude Oil sensor with the DataBank, our handheld datalogger; and the Trilogy Laboratory Fluorometer for discrete sampling.

Instruments In Action

fluorometerU.S. Coast Guard SMART Team
Coast Guard Petty Officer 2nd Class Kurt Stricklen and crew, members of a Coast Guard Special Monitoring of Applied Response Technologies (SMART) team, collect oiled water samples in the Gulf of Mexico using the C3 Submersible Fluorometer. The team of specialists in oil-spill and hazardous substance monitoring use state-of-the-art technology to gather samples and field data which help environmental scientists determine the effectiveness of dispersants used to break down oil in the water.

Seakeepers Society Using the C3 Multi-Sensor Platform to Track the Gulf Spill
The Seakeepers Society has integrated our C3 Submersible Fluorometer configured with oil optics with their SeaKeeper 1000 oceanographic and atmospheric data acquisition system to track the Gulf Spill. Read the article "USA Seakeepers' detection technology embraced for Gulf crisis" published on BYM Marine Environment News.

Sea School in Florida Using Turner Designs Fluorometers to Track the Gulf Oil Spill
Sanibel Sea School in Florida is using the Cyclops-7 Submersible Fluorometer configured with crude oil optics and partnered with the DataBank Handheld Datalogger to check for oil in local waters.

New Products and Accessories

Refined Fuels Optics
Turner Designs now offers Deep UV Optical sensors for detection of Refined Fuels and Oils. Recent developments in LED technology allow for excitation wavelengths down to 260nm. Using BTEX as the standard, the sensors are able to detect as low as 0.1ppm and have a dynamic range of 0 - 2500 ppm. Both the Cyclops-7 and C3 Submersible Fluorometers can be purchased with Deep UV optics offering some of the lowest cost solutions for in situ detection of refined fuels and oils.

C3 Submersible Fluorometer now has Analog Output
The Turner Designs C3 Submersible Fluorometer is now available with an Analog Output Adapter which outputs a 0-5 VDC signal for 1, 2, or 3 channels depending on the C3 configuration. The adapter enables integration with CTDs or any dataloggers that accept a 0-5 VDC signal. It plugs directly into the C3 and is securely held in place by the battery bracket. The C-Soft Windows-based user interface allows for intuitive C3 calibration, data logging, and data management.

Introducing the C-ray
fluorometerThe C-ray (PN 2300-750), an in situ deployment body for the C3 that allows the fluorometer to be towed horizontally through the water at low speeds, is being used as part of the SMART oil spill response protocol in the Gulf of Mexico. Following the protocol, fluorescence measurements, as well as temperature and depth, are integrated with position data from GPS systems providing an accurate picture of the distribution of oil in water that simple profiling can not.

C3/C6 Integration Cables
The C3 and C6 can be set up for autonomous operation; collecting data for days, weeks or months. If, for whatever reason, the PC collecting the data reboots it can interrupt the data transmission from the fluorometer. Turner Designs released the C3/C6 integration cable as a preemptive measure against this potential problem.

fluorometer The Integration Cable is identified by the yellow shrink tube seen here. The Integration Cable can not be used for firmware upgrades.

Lawrence's Corner

This e-mail address is being protected from spambots. You need JavaScript enabled to view it What is Crude Oil?
Crude Oil is simply unprocessed oil found deep beneath the earth's surface. It can range in color from clear to black and can be found as a liquid or solid. Generally, crude oils are made up of hydrocarbon compounds. The main hydrocarbons found in crude oil are Aliphatics, Alicyclics, and Polycyclic Aromatic Hydrocarbons (PAHs). The aromaticity, chemical composition, or molecular structures of these compounds in crude oil play a key role in determining their fluorescence intensities and emission wavelengths (Figure 1 below).

2 - Shell Diala oil
3 - Oil SAE 30
4 - Bunker Fuel oil
5 - Arabian Medium crude oil
6 - Basra crude oil
7 - German crude oil
8 - Nihian crude oil

Fluorimetry is required for detecting low concentrations, determining fraction dissolved, and tracking horizontal and vertical distribution of oil in water. Turner Designs' Cyclops-7 and C3 Submersible Fluorometers are two in situ fluorometers that can be configured with crude oil optics specifically for detecting the fluorescence of crude oil in water. These instruments can be calibrated with specific crude oil standards or samples with known concentration for the purpose of obtaining quantitative values of oil in water. Another option is to simply calibrate the instruments using a blank sample (either de-ionized water or filtered natural water that does not contain oil) and measure relative fluorescence values to qualitatively analyze oil in water. Either calibration proves useful for determining changing oil concentrations in water.

Figure 2 (below) is an example of how Turner Designs' crude oil optics, namely the Cyclops-7 Crude Oil Fluorometer, respond to the addition of Osberg crude oil to de-ionized water. Crude oil was mixed into the water in a stepwise manner increasing in concentration from 0 - 2 parts per million (ppm) of Osberg crude oil (as emulsions) in water. These data are also an example of how users can establish linearity, create a calibration curve, or determine resolution and limits for the oil specific to their study.
