The presence of low-lying stratocumulus clouds and fog has been known to modify biophysical and ecological properties in coastal California where forests are frequently shaded by low-lying clouds or immersed in fog during otherwise warm and dry summer months. Summer fog and stratus can ameliorate summer drought stress and enhance...

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....

The 1994 Northwest Forest Plan (NWFP) shifted federal lands management from a focus on timber production to ecosystem management and biodiversity conservation. The plan established a network of conservation reserves and an ecosystem management strategy on ~10 million hectares from northern California to Washington State, USA, within the range of...

Multibeam (1 m resolution) and side scan data collected from an autonomous underwater vehicle, and
lava samples, radiocarbon-dated sediment cores, and observations of flow contacts collected by remotely
operated vehicle were combined to reconstruct the geologic history and flow emplacement processes on
Axial Seamount’s summit and upper rift zones. The...

Geologic history of the summit of Axial Seamount, Juan de Fuca Ridge
Clague, D. A. et al
Axial Seamount, an active submarine volcano on the Juan de Fuca Ridge at 46°N, 130°W, erupted in
January 1998 along 11 km of its upper south rift zone. We use ship-based multibeam sonar, high-resolution
(1 m) bathymetry, sidescan sonar imagery, and submersible dive observations to map four
separate 1998 lava...

In the future, Earth will be warmer, precipitation events will be more extreme, global mean sea level will rise, and many arid and semiarid regions will be drier. Human modifications of landscapes will also occur at an accelerated rate as developed areas increase in size and population density. We now...

Stressors associated with human activities interact in complex ways to affect marine ecosystems,
yet we lack spatially explicit assessments of cumulative impacts on ecologically and
economically key components such as marine predators. Here we develop a metric of
cumulative utilization and impact (CUI) on marine predators by combining electronic tracking...

Subtropical marine stratus clouds regulate coastal and global climate, but future trends in these
clouds are uncertain. In coastal Southern California (CSCA), interannual variations in summer stratus cloud
occurrence are spatially coherent across 24 airfields and dictated by positive relationships with stability
above the marine boundary layer (MBL) and MBL...

The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics)
program examined zooplankton populations and their predators in four coastal
marine ecosystems. Program scientists learned that environmental controls on
zooplankton vital rates, especially the timing and magnitude of reproduction, growth,
life-cycle progression, and mortality, determine species population dynamics,
seasonal and spatial distributions,...
