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
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.

their SeaKeeper 1000 oceanographic and atmospheric data acquisition
system to track the Gulf Spill. Read the article "USA

Products and Accessories
Refined Fuels Optics
Turner Designs now offers Deep UV Optical sensors for detection
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
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
C-ray (PN 2300-750), an in situ deployment body for
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
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.
Integration Cable is identified by the yellow shrink tube
seen here. The Integration Cable can not be used for firmware

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

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
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.

oil mixed into water as emulsions, measured using Cyclops-7
Fluorometer configured with crude oil optics. Readings
were taken on the most sensitive gain setting.
