Terrigenous Fe input and biogenic sedimentation in the glacial and interglacial equatorial Pacific Ocean

Creator:: Murray, R. W., Leinen, M., Murray, D. W., Mix, Alan C., and Knowlton, C. W.
Abstract:: Many ocean regions important to the global carbon budget, including the equatorial Pacific Ocean, have low chlorophyll concentrations despite high levels of conventional nutrients. Iron may instead by the limiting nutrient, and elevated input of terrigenous Fe during windy glacial episodes has been hypothesized to stimulate oceanic productivity through time...

Export production and carbonate dissolution in the central equatorial Pacific Ocean over the past 1 Myr

Creator:: Murray, R. W., Knowlton, C. W., Leinen, M., Mix, Alan C., and Polsky, C. H.
Abstract:: In order to quantify changes in export production and carbonate dissolution over the past 1 Myr in the central equatorial Pacific Ocean we analyzed Ba, P, Al, Ti, and Ca in 1106 samples from five piston cores gathered from 5°S to 4°N at 140°W. We focused on Ba/Ti, Al/Ti, and...

Fine-scale variability at 140°W in the Equatorial Pacific

Creator:: Chereskin, T. K., Moum, James N., Stabeno, P. J., Caldwell, Douglas R., Paulson, C. A., Regier, L. A., and Halpern, D.
Abstract:: In November-December 1984 we carried out an intensive 12-day upper ocean sampling program on the equator at 140°W as part of the Tropic Heat Experiment. From our observations we constructed hourly averaged profiles of temperature, salinity, σ₁, turbulent kinetic energy dissipation rate, and horizontal velocity. These data were used to...

Primary Production Estimates from Recordings of Solar-Stimulated Fluorescence in the Equatorial Pacific at 150°W

Creator:: Stegmann, P. M., Lewis, M. R., Davis, C. O., and Cullen, J. J.
Abstract:: Biological, optical, and hydrographical data were collected on the WEC88 cruise along 150°W and during a 6-day time series station on the equator during February/March 1988. This area was characterized by a subsurface chlorophyll maximum (SCM), located at 50–70 m depth at the equator and descending down to 120–125 m...

Phenology and Productivity of C₃ and C₄ Grasslands in Hawaii

Creator:: Pau, Stephanie and Still, Christopher J.
Abstract:: Grasslands account for a large proportion of global terrestrial productivity and play a critical role in carbon and water cycling. Within grasslands, photosynthetic pathway is an important functional trait yielding different rates of productivity along environmental gradients. Recently, C₃-C₄ sorting along spatial environmental gradients has been reassessed by controlling for...

Securing ocean benefits for society in the face of climate change

Creator:: Ruckelshaus, M., Doney, S. C., Galindo, H. M., Barry, J. P., Chan, F., Duffy, J. E., English, C. A., Gaines, S. D., Grebmeier, J. M., Hollowed, A. B., Knowlton, N., Polovina, J., Rabalais, N. N., Sydeman, W. J., and Talley, L. D.
Abstract:: Benefits humans rely on from the ocean - marine ecosystem services - are increasingly vulnerable under future climate. This paper reviews how three valued services have, and will continue to, shift under climate change: (1) capture fisheries, (2) food from aquaculture, and (3) protection from coastal hazards such as storms...

High electron mobility W-doped In₂O₃ thin films by pulsed laser deposition

Creator:: Newhouse, Paul F., Park, C.-H., Keszler, Douglas A., Tate, J., Nyholm, P. S., and Tate, Janet
Abstract:: High electron mobility thin films of In₂₋ₓWₓO₃₊y(0≤x≤0.075) were prepared on amorphous SiO₂ and single-crystal yttria-stablized zirconia (001) substrates by pulsed laser deposition. Mobilities ranged between 66 and 112 cm² /Vs depending on the substrate type and deposition conditions, and the highest mobility was observed at a W-dopant concentration of x~0.03....

Initiation of the spring phytoplankton increase in the Antarctic Polar Front Zone at 170°W

Creator:: Landry, Michael R., Brown, Susan L., Selph, Karen E., Abbott, Mark R., Letelier, Ricardo M., Christensen, Stephanie, Bidigare, Robert R., and Casciotti, K.
Abstract:: During austral summer 1997, satellite imagery revealed enhanced chlorophyll associated with the Antarctic Polar Front at 170°W. Phytoplankton growth conditions during the early stages of the spring increase were investigated on the Antarctic Environment and Southern Ocean Process Study Survey I cruise using flow cytometry (FCM) and microscopy to characterize...

Optical and hydrographic observations of the Cromwell Current between 92°00'W and the Galapagos Islands

Creator:: Zaneveld, J. Ronald, Pak, Hasong, and Plank, William S.
Abstract:: Optical and hydrographic observations were made at two meridional sections across the Cromwell Current at 92°00’ and 91°40’W during February 1969. The distribution of hydrographic and optical properties near the Galapagos Islands is described. Beneath the thermocline the Cromwell Current is characterized by deepening of the light-scattering isolines. Above the...

A Motion-Stabilized W-Band Radar for Shipboard Observations of Marine Boundary-Layer Clouds

Creator:: Moran, Ken, Pezoa, Sergio, Fairall, Chris, Williams, Chris, Ayers, Tom, Brewer, Alan, de Szoeke, Simon P., and Ghate, Virendra
Abstract:: Cloud radars at X, Ka and W-bands have been used in the past for ocean studies of clouds, but the lack of suitable stabilization has limited their usefulness in obtaining accurate measurements of the velocity structure of cloud particles and the heights of cloud features. A 94 GHz (W-band) radar...
