Fertile Soil for Teaching

Fertile Soil for Teaching

It’s not every researcher that wears a hard hat and works around dynamite. But Dr. Holly Dolliver of the University of Wisconsin—River Falls embraces the unique parts of studying soil at a frac sand mining site. Wisconsin law requires that land used for mining must be reclaimed, so Dr. Dolliver is part of a five-year research program to see how soils react to being stripped, stockpiled, and respread. “Our emphasis is to understand holistically how the soil responds to disturbance,…

Eddy Covariance Port Forwarding and Blocking

Eddy Covariance Port Forwarding and Blocking

Why does remote connectivity through a cell modem to a LI-COR eddy covariance system work from certain Internet connections and not from others?

LI-COR eddy covariance systems can have several devices which use the TCP/IP protocol, and they can all be connected to a modem which has access to the Internet. A port forwarding rule is set up in the modem, so that communications arriving through certain ports are forwarded to specific instruments. For example, the LI-7200RS CO2/H2O analyzer communicates…

R3 and HS Sonic Anemometer Configuration

R3 and HS Sonic Anemometer Configuration

The Gill R3 and HS series of anemometers can be connected to the LI-7550 to collect data on a USB drive.  This can facilitate remote data monitoring and collection through the available Ethernet connectivity.

The anemometer will have to be preconfigured to send data out in the required format. This can be achieved using any serial communication software like Windows HyperTerminal or Tera Term (which can be downloaded for free here). You can also use the WindCom or RCom2…

Using the LI-6800 in Undergraduate Environments

Using the LI-6800 in Undergraduate Environments

Dr. Jason Kilgore, an associate professor of biology at Washington & Jefferson College, has been using top-notch research instrumentation to enhance undergraduate learning. As a member of the Ecological Research as Education Network (EREN), which is a collaborative network of schools that are primarily undergraduate institutions, Dr. Kilgore and other EREN faculty “use authentic research as a model for students to learn about biology.” He does so by incorporating an LI-6800 Portable Photosynthesis System into his coursework and student research.

7200-101 Flow Module – High Frequency Noise Reduction

7200-101 Flow Module – High Frequency Noise Reduction

In some situations, the 7200-101 Flow Module may emit high frequency noise through its exhaust port. This may occur if the motor drive of the Flow Module is ramped up to maintain the flow rate as pressure drops in the flow path.

Inline filters that clog up over time may cause a significant motor drive increase, especially if the inline filter is not replaced before the motor drive reaches its maximum at 100%.

Silencer

The silencer shown below in Figure…
