We use the position fixes and temperature readings from 56 Tristar-II mixed-layer drifters, in conjunction with advanced very high resolution radiometer images, to provide a description of the mesoscale variability of the flows associated with...

Measurements at the Hawaii Ocean Time-series (HOT) Station ALOHA (22 degrees 45'N, 158 degrees W) have revealed a significant, approximately 50% increase in euphotic zone depth-integrated rates of primary production ( PP; mol C fixed m(-2) d(-1))...

Observations, from the Oregon continental shelf, describe the slumping of a coastal
upwelling front in response to a reversal of winds from upwelling-to downwelling-favorable.
Initially, the front outcropped in a surface mixed layer of depth 10–20...

During March–April 1999, 2 weeks of undulating CTD and shipboard acoustic
Doppler current profiler surveys revealed the variability of the intense internal tide on the
northern edge of Georges Bank. The nature of the internal tide was modulated by...

Velocity measurements from 17 deployments of moored acoustic Doppler current
profilers obtained during four summer upwelling seasons are used to describe the crossshelf
divergence of Ekman transport in the inner shelf off Oregon. For each...

In the northern California Current, the onset of the 2005
upwelling season was five weeks later than usual, and well established
upwelling with a cold surface signature did not
occur until about seven weeks after this. As part of the joint...

Meanders of the shelf break front in the Mid-Atlantic Bight (MAB)
during April and May of 1997 were associated with chlorophyll enhancement along
a hydrographic and a topographic feature. The hydrographic feature was the
surface outcrop of the...

Hydrographic observations made with an undulating vehicle carrying a CTD and
concurrent shipboard ADCP velocity observations over a 12-day period are combined to
investigate vertical mixing and cross-frontal fluxes on the Northern Flank of...

Airborne measurements over the northern Pacific are
evaluated to characterize properties of black carbon (BC) in
cirrus crystal residuals and background aerosols in the upper
troposphere. Although the mass and number concentrations
of BC were 7–25...

The first reliable aircraft measurements of characteristic
cloud drop charges were obtained by utilizing a
counterflow virtual impactor to substantially increase
charge sensitivity and eliminate spurious contact charging
that contaminated previous...

The concentrations of atmospheric gases and condensation nuclei (CN) or aerosol in
the outflow of a storm were measured aboard a NASA DC-8 aircraft, as described in a
companion paper [Twohy et al., 2002]. The data are used here to study the...

Aircraft-based in situ measurements of cirrus cloud ice water content (IWC) are
important for cloud microphysical/radiative modeling and satellite validation studies, yet
the measurements have proven challenging due, in part, to the large dynamic...

A temperature spectrum if heterogeneous freezing nuclei concentrations in continental air in the upper troposphere was determined based on airborne measurements. Numerical model simulations incorporating ice formation by heterogeneous and...

At low latitudes, cirrus are ubiquitous and can be in
excess of 100°C colder than the surface, limiting the
amount of sunlight absorbed by the earth’s atmosphere and
surface, and reducing its loss of heat. Here we present
aircraft measurements...

Measurements of ice water content (IWC) and
mean ice-crystal size and concentration made by two in-situ
probes, C, VI and PVM, were compared on the DC-8 aircraft
during SUCCESS flights in orographic ice clouds. The
comparison of 1WC in these wave...

Microphysical and chemical aerosol measurements collected during DYCOMS-II
research flights in marine stratocumulus clouds near San Diego in 2001 were used to
evaluate the partitioning of 18 organic and elemental components between droplet...

Relative humidity (RH) measurements
acquired in orographic wave cloud and cirrus environments
are used to investigate the temperature dependent
RH required to nucleate ice crystals
in the upper troposphere, RHnuc(T). High ice-supersaturations in...

We have compared in situ measurements
near the leading-edges of wave-clouds observed during
the SUCCESS experiment with numerical simulations.
Observations of high supersaturations with respect to ice (> 50%) near the leading edge of a very cold...

On 3 April 2001, a 20 kg point source of fluorescein dye was released 30 m above the
bottom of the active summit caldera of Vailulu’u submarine volcano, Samoa. Vailulu’u
crater is 2000 m wide and at water depths of 600–1000 m, with the bottom 200...

Over the last three decades the first-order correlation in morphology and orientation of seamount trails
has been called upon to support the concept of a ‘‘fixed’’ Pacific hot spot frame of reference and to explain
the Hawaii-Emperor bend (HEB) by...

Vailulu'u Seamount is identified as an active volcano marking the current location of the Samoan hotspot. This seamount is located 45 km east of Ta'u Island, Samoa, at 169°03.5′W, 14°12.9′S. Vailulu'u defines the easternmost edge of the Samoan...
