included critically dry years and years with above normal and near-record precipitation and discharges from the major rivers
and local streams. Data collection at 15-minute intervals allowed resolution of variability associated with daily tides and other
short-term phenomena. Both local stream discharges to South San Francisco Bay and Sacramento-San Joaquin River
discharges to North San Francisco Bay affected salinity at Dumbarton Bridge. Salinity at Dumbarton Bridge varied with the
daily tides, and the lowest salinity values (annual) coincided with precipitation and freshwater inflows usually in winter.
Short-term and seasonal variations in temperature at Dumbarton Bridge typically followed changes in air temperature and
solar irradiance.

The primary accomplishments of the JOI Cooperative Agreement with DOE/NETL in this quarter was the preparation of
tools and measurement systems for deployment, testing and use on ODP Leg 204, which will study hydrate deposits on
Hydrate Ridge, offshore Oregon. Additional accomplishments were related to the post-cruise evaluation of tools and
measurements systems used on ODP Leg 201 along the Peru margin from January through March, 2002.

The chemical and isotopic (11B/10B, 87Sr/86Sr, 180/160, 2H/H, 13C/12C, 14C, 3He/3H) compositions of groundwater
from the upper aquifer system of the Salinas Valley in coastal central California were invesugated in order to delineate the
origin and processes of groundwater contamination in this complex system. The Salinas Valley has a relatively deep, confined
‘400-foot’ aquifer, overlain by a ‘180-foot’ aquifer, and a shallower perched aquifer, all made up of alluvial sand, gravel, and
clay deposits. Groundwater from the aquifers have different t4C ages; fossil (14C=21.3 pmc) for the 400-foot, and modern
(14C=72.2 to 98.2 pmc) for the 180-foot. Fresh groundwater in all aquifers is recharged naturally and artificially and through
the Salinas River. The two modes of recharge can be distinguished chemically.

Our goal is to improve geophysical imaging of the vadose zone. We are achieving this goal by providing new methods
to improve interpretation of field data. The purpose of this EMSP project is to develop relationships between laboratory
measured geophysical properties and porosity, saturation, and fluid distribution, for partially saturated soils. Algorithms for
