The LI-8100 Automated Soil CO2 Flux System - Frontiers in Ecology ...

The LI-8100 Automated Soil CO 2 Flux System
LI-COR’s Multiple-Chamber Solution
8100-101 Long-Term Chamber
uses a strut mechanism that
opens and closes the chamber
in a 180° vertical arc.
The data set above was collected with an LI-8100 System and LI-8150 Multiplexer in
a soybean field in eastern Nebraska (USA). Spatial variability in soil CO 2 flux within
the 16-chamber system is significant, with the Coefficient of Variation averaging
more than 20%. Strong temporal variability, a result of diurnal soil temperature
change, is also evident in the data.
Why are Automated, Multiple-Chamber
Measurements Necessary?
High spatial and temporal resolution of soil CO 2 flux rates is
essential in understanding how biological and environmental
variables regulate the flux. Manual measurements often fail to
accurately capture spatial and temporal variations in soil CO 2
flux. Therefore, an automated, long-term, multiple-chamber
solution is necessary; this solution can be found in the LI-8100
System and LI-8150 Multiplexer from LI-COR:
■ Measure up to 16 chambers
■ 30 m diameter coverage
■ Single CO 2 /H 2 O gas analyzer (no measurement bias)
■ Unattended deployment for weeks or months at a time
8100-104 Long-Term Chamber
uses a lift-and-rotate drive
mechanism that lifts the
chamber slightly and then
moves horizontally to any of
6 open positions.
LI-8150 Multiplexer
■ Multiplex up to 16 long-term
chambers
■ Assess spatial and temporal
variability

“The Deep is not only the most stunningly beautiful book about the sea
ever produced, but also a work of scientific substance, articulated by some
of the best, most experienced deep-sea scientists of our time.”
—Sylvia Earle, National Geographic Society

“I know of no other work that provides such a comprehensive review
of the history of deep-sea exploration. The Silent Deep will be readily
understood and appreciated by the general reader.”—Richard Lutz,
Rutgers University
Oceans collects more than thirty articles from the past decade of
Scientific American, including recent pieces written in the wake of the
2004 tsunami. The book features articles that investigate the origins of
the world’s oceans, the diversity of life in the water, the state of global
fisheries, the dangers of natural disasters, and the imprints of humans
on this fragile frontier.
Ethical Issues in Ecology: Case studies is a must for
stimulating lively discussions in a variety of educational
settings, including college classrooms, workshops and
courses, lab group meetings, and in-house seminars.
Jeff Dudycha and Kevin Geedey present a series of
thought-provoking fictional scenarios to highlight the
ethical dilemmas faced by ecologists and other research
scientists today. Linked commentaries give general
guidance to group leaders and teachers, helping them to
avoid common pitfalls and to keep the discussion moving.
Based on the highly popular Ethical Issues series in
ESA’s journal Frontiers in Ecology and the
Environment, this readable introduction to ethical
debate can be used by anyone – no formal training in
ethics required.
“Ultimately, the ecologist’s toolkit needs to include
methods for dealing with ethical issues”

The CI-600 Root Scanner is designed to scan
living roots in the soil. It is operated by a
laptop computer. To obtain an image, insert
the scan head into a pre-installed Plexiglass
tube. The scan head will automatically rotate
a full circle, creating a 21.59 × 19.56 cm highresolution
image of the soil and roots. Users
can move the scan head to different depths,
and move from tube to tube.
A flat scanner model is also now available.
Up to 188 million pixels super highresolution
image.
Linear scanning with no distortion.
Very portable and quick operation.
Zoom in to any area of a
scanned image.
