Introduction
fluorometer
I’m always smiling when the longest section of our newsletter is Instruments in Action. There’s nothing I love more than learning about how our customers are using our instruments. And, I have to admit, I found special joy in TERC’s approach of using crowd-funding for their project to improve the health of Lake Tahoe. If movie-makers can do it, why can’t scientists? On a non-water related note, read the last article of this newsletter for a fun story about recent tenants in our building.

Thanks to all our customers for keeping us in the loop on how your projects are progressing.

Best Regards,
Pam Mayerfeld

VP of Marketing & Sales

Red Excitation Chlorophyll Sensor ideal for environments rich in Organic Materials

Turner Designs recently developed an in vivo chlorophyll sensor that uses a red excitation light source to elicit a fluorescence response from algae. This sensor is ideal for environments rich in Dissolved Organic Matter (DOM) and blue-green algae. DOM has long been known to interfere with blue excitation fluorometry, minimizing accuracy of chlorophyll concentration and algal abundance estimates because DOM absorbs at similar blue wavelengths as algae.  >>Read More

The Nearshore Network - Instrumenting Lake Tahoe

The UC Davis Tahoe Environmental Research Center (TERC) has been working to launch the world’s first, real-time Nearshore Network comprised of approximately 20 sites around the Tahoe basin. The first six stations, spanning both California and Nevada, were installed in August.

Each station consists of a Turner Designs C3 Submersible Sensor measuring turbidity, algal concentration, and dissolved organic material along with a RBRmaestro multi-channel logger measuring water temperature and conductivity. An underwater cable supplies power to each station and returns data, which are displayed as near real-time and can be accessed via the internet. More stations will be added in the future as additional funding is acquired.

Why are these nearshore data so important? >>Read More

Liquid Robotics and Turner Designs: Real-time oil seep surveillance in the Gulf of Mexico

In the Gulf of Mexico’s Mississippi Canyon, you’ll find undersea salt domes and mud volcanoes, known sources of natural oil seeps that rise to the surface of the ocean, producing oil slicks. These natural seeps can indicate the presence of energy reserves, both liquid and gas, and are of keen interest to the world’s oil and gas companies. Hydrocarbons that rise to the surface form very thin oil patches and surface slicks that are short lived. Traditionally, satellites along with ship-borne sampling have been used for hydrocarbon detection, but these methods are expensive and have limited ability to capture real-time events. The challenge: how to continuously monitor for these time-sensitive oil seeps in deep waters? >>Read More

Lamar Academy Students use Cyclops-7 Sensors for Summer Studies

Turner Designs partnered with students from McAllen Independent School District’s International Baccalaureate Program (IB) at Lamar Academy during the summer of 2014. These students participated in an annual Marine Ecology Camp through the IB school and The University of Texas - Pan American in Edinburg, Texas. This year, in addition to their work on seagrass physiology, mangrove production, leaf fall, and decomposition dynamics, these students used chlorophyll, phycocyanin, and tryptophan Cyclops-7 submersible sensors to assess the water quality of the Arroyo Colorado, one of the most human-impacted streams in the State of Texas. The Arroyo Colorado discharges into the waters of the Lower Laguna Madre, renowned for its abundant seagrass communities and commercial fishing. The biota of the Laguna Madre are sensitive to poor water quality and human waste discharge. >>Read More

Delaware River Dye Study

The Philadelphia Water Department conducted a dye test in the Delaware River between August 5 and August 8, 2014, as part of the validation process for a 3D hydrodynamic model using Environmental Fluid Dynamics Code. They are updating a flow model that will help them better understand how pollutants are dispersed in the tidal Delaware. This flow model is one of the scientific tools used in their Green City Clean Waters Plan to better protect and improve the quality of the Delaware River.

The dye chosen for this study, Fluorescein, is a green-colored fluorescent compound first synthesized in 1871. Fluorescein is the most commonly used dye for both surface and groundwater tracing studies. It is non-toxic, photodegradable, considered harmless to humans and has no environmental impacts, especially for the amounts used for this study. After injection, the dye plume was visible for approximately three hours as a light tinge of green on the surface of the water.  >>Read More

Integrating your C-sense pCO2 sensor to a Campbell Scientific CR1000 Datalogger
With the introduction of our C-sense in-situ pCO2 sensor, we received numerous inquiries about integration with various dataloggers, one of the most popular being the Campbell Scientific CR1000. In response to this, we implemented this integration and created a document outlining the procedure. Because C-sense operation is relatively simple, supplying a 0-5 V analog output signal proportional to pCO2 concentration, the integration is straightforward. The CR1000 handles this type of generic output while also supplying power to the C-sense.

Shade cap recommendation for Cyclops-7s and C3/C6 Submersible Instruments
If you ever sat by the side of the pool and watched the patterns of light play on the bottom, then you have seen the effect which ambient light can have on optical instruments. Turner Designs instruments are optical sensors that can be influenced by extraneous light. In the case of Cyclops-7, C3 and C6 Submersible Sensors, light from shallow and near surface sampling can impact readings. For all these instruments we recommend the use of a shade cap. The shade cap provides a fixed distance for sample measurement and minimizes the effects of ambient light. The shade cap also offers protection for the optics preventing damage during deployment, recovery, or transporting the instrument.
Additionally, the shade cap can be used for calibrating instruments. It acts as an optical backstop for the sensor and requires a smaller volume standard when compared to the alternative. This accessory is recommended for obtaining accurate and reliable data with minimal ambient interference. Links to the shade cap instructions and information are below:

Front & Center in ECO Magazine
ICAM was featured in the June, 2014 issue of ECO magazine in an article written by Lawrence Younan, Turner Designs’ Applications Scientist (view article).
Response to the ICAM from beta users has been positive. We’re particularly excited to share new data showing the minimal effect of scattering on ICAM absorption measurements. For this reason alone, the ICAM represents a superior method of measuring absorption.

New tenants at Turner Designs
Last July, one of our conference rooms was literally buzzing with activity. We pulled the blinds aside and found dozens of bees inside the window. Not wanting to disturb them, we closed the door and called Bee Removal, an environmentally-safe live bee removal company. Their theory was that bees had taken residence in our walls. They asked us to run our hand down the walls and tell them if we felt anything. Sure enough, there was an area of the wall that was incredibly warm. That was the clue they were looking for – bees were building a hive in our wall. They came out the next day to do a live removal of all bees, honey and hive. Dressed in full protection gear, they carefully vacuumed out the queen and waited for all the other bees to follow her into their box.
Several hours later the box was taken away to a safe environment. Bee Friendly rents the bees out to farmers for pollination purposes. Our building is once again bee-free and we are in awe of how carefully the bee keepers worked to protect the bees.
