Understanding the processes that control the terrestrial exchange of carbon is critical for
assessing atmospheric CO₂ budgets. Carbonyl sulfide (COS) is taken up by vegetation during
photosynthesis following a pathway that mirrors CO₂ but has a small or nonexistent emission component,
providing a possible tracer for gross primary production. Field...

The movement of moisture into, out-of, and within forest ecosystems is modulated
by feedbacks that stem from processes which couple plants, soil, and the atmosphere.
While an understanding of these processes has been gleaned from Eddy Covariance
techniques, the reliability of the method suffers at night because of weak turbulence....

Quaking aspen (Populus tremuloides Michx.), a widespread and keystone tree species in North America, experienced heat and drought stress in the years 2002 and 2003 in the southwestern United States. This led to widespread aspen mortality that has altered the composition of forests, and is expected to occur again if...
The BEST (Benguela Source and Transport) project was designed to investigate the form
of the Benguela Current and ratio of the Aguhlhas Current and South Atlantic Current
source waters masses. The transport of the Benguela Current and its variability was
measured by a moored array of instruments, inverted echo sounders...
The Samoan Passage experiment was designed to determine the northward transport of abyssal water through the Samoan Passage (l0°S, 170°W). This topographic constriction forms the major connection for deep (>4000 m) interbasin flow between hemispheres in the Pacific (Figure 1). This report presents current meter data from the six subsurface...
