Solar Eclipse Data from LI-COR

Solar Eclipse Data from LI-COR

On Monday, the LI-COR campus was in the path of totality for the August 21, 2017 solar eclipse. Here are data collected during the eclipse at our campus in Lincoln, Nebraska, USA. Even though cloud cover obscured our direct view of the eclipse, there were observable differences in light intensity, photosynthesis measurements, and environmental flux during totality.

The partial eclipse began around 11:37 AM CST, with totality happening from 1:02 PM to 1:04 PM. The eclipse was over by 2:37…

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.

LI-6800 Leaf Temperature Thermocouple Height

LI-6800 Leaf Temperature Thermocouple Height

Leaf temperature is an important input to many parameters calculated on the LI-6800, including stomatal conductance (gsw) and leaf intercellular CO2 concentration (Ci). The LI-6800 leaf temperature probe is a Type E thermocouple mounted on flexible material (Figure 1). The thermocouple junction is a ~0.008” diameter bead. The bead is too small to be seen without magnification (Figure 2).

Accurate measurement of leaf temperature requires that the thermocouple bead be high enough to ensure it is making contact with the…

Photosynthesis Modelling Researcher Awarded 2015 Prime Minister’s Prize for Science

Photosynthesis Modelling Researcher Awarded 2015 Prime Minister’s Prize for Science

Professor Graham Farquhar, Australian National University, was awarded the Prime Minister’s Prize for Science for his work on better understanding photosynthesis. His research has led to the creation of more water-efficient crops, and his models of plant biophysics have enhanced the understanding of plant cells.
