Recent findings indicate that ENSO may modulate the
strength of the Indian monsoons by altering the meridional
tropospheric temperature gradient between Asia and the
equatorial Indian Ocean. Here we show that during northern
hemisphere summertime...

Port Orford is a small fishing community on the southern Oregon coast. Like many coastal towns in Oregon, Port Orford's main economy is the commercial fishing industry. As such, the community has a high dependence on its nearshore marine...

Under conditions of fixed N-limitation, as with most oligotrophic systems, the process of biological N₂ fixation (diazotrophy) is favored, provided the necessary trace elements and vitamins are sufficient. Despite the well understood contributions...

We used a dynamic hydrology model to simulate water table depth (WTD) and quantify the relationship
between Saint Louis encephalitis virus (SLEV) transmission and hydrologic conditions in Indian River
County, Florida, from 1986 through 1991, a...

We modeled surface wetness at high resolution, using a dynamic hydrology model, to predict flood and
swamp water mosquito abundances. Historical meteorologic data, as well as topographic, soil, and vegetation
data, were used to model surface...

Disease transmission forecasts can help minimize
human and domestic animal health risks by indicating
where disease control and prevention efforts should be
focused. For disease systems in which weather-related
variables affect pathogen...

Much of the observed wintertime increase of mortality in temperate regions is attributed to seasonal influenza. A recent
reanalysis of laboratory experiments indicates that absolute humidity strongly modulates the airborne survival and...

This study presents two new modeling strategies. First, a methodology for
representing the physical process of subsurface storm flow within a TOPMODEL
framework is developed. In using this approach, discharge at quick flow timescales is
simulated,...

Hydrologic processes control much of the export of organic matter and nutrients from
the land surface. It is the variability of these hydrologic processes that produces variable
patterns of nutrient transport in both space and time. In this paper,...

Measurements of the U₃₇ K’ index and the absolute abundance of alkenones in marine
sediments are increasingly used in paleoceanographic research as proxies of past sea surface
temperature and haptophyte (mainly coccolith-bearing species) primary...

We use data from a series of small (three to five stations) overlapping magnetovariational (MV) arrays to
image variations of vertically integrated electrical conductivity in the crust of southwestern Washington. Two
principal structures are...

We assimilate localized mass anomalies inferred from
GRACE ranging measurements into a hydrodynamic model
to improve tidal solutions around Antarctica for the M2, S2,
and O1 constituents. The variational approach used accounts
for the spatial...

Eleven years (1932-1942) of electric potential and magnetic measurement at the Tucson observatory
represent a unique very long period magnetotelluric (MT) data set. We report here on a careful reanalysis of this
data using modern processing...

I derive probability densities for virtual geomagnetic pole( VGP) longitudes for a general statistical model of
local magnetic field variations. I show that even for very
simple statistically homogeneous models of secular variation,
the...

Spectral analysis of the time-varying horizontal magnetic and electric field components yields
the magnetotelluric (MT) impedance tensor. This frequency dependent 2x2 complex tensor
can be examined for details which axe diagnostic of the...

Magnetotelluric exploration has been used to
image along strike variations in the electrical resistivity
structure of the San Andreas Fault at Parkfield, California.
A low resistivity wedge extending to a depth of several
kilometers is continuous...

A magnetotelluric (MT)transect has been obtained near latitude 45øN from the active Juan de Fuca
Spreading center, across the subduction zone and Cascades volcanic arc, and into the back arc Deschutes
Basin region. This paper presents the MT data...
