Jet stream intraseasonal oscillations drive dominant ecosystem variations in Oregon’s summertime coastal upwelling system

Creator:

Bane, John M., Spitz, Yvette H., Letelier, Ricardo M., and Peterson, William T.

Abstract:

Summertime wind stress along the coast of the northwestern United States typically exhibits intraseasonal oscillations (ISOs) with periods from ≈15 to 40 days, as well as fluctuations on the 2- to 6-day “weather-band” and 1-day diurnal time scales. Coastal upwelling of cool, nutrient-rich water is driven by extended periods of...

Correlations of sea surface height and solid earth tides with seismicity in the equatorial Pacific Ocean : a GIS approach

Creator:

Zennaro, Barbara

Abstract:

In the equatorial Pacific Ocean, earthquakes are used as an indicator of tectonic stress for normal faults in the Galapagos Spreading Center, transform faults along the East Pacific Rise and thrust faults in the Middle American subduction zone. Linkages between seafloor tectonic processes and oceanographic and lunar conditions were explored...

Masters Thesis
Geochemical and helium isotopic variability within the Lau Basin

Creator:

Goddard, Charlotte Ives

Abstract:

This research incorporates geochemical and helium isotopic analyses of Lau Basin volcanic glasses, along with helium isotopic analyses of water column hydrothermal plumes to better understand the processes that control the formation and evolution of this backarc basin. Lavas newly collected from the four southernmost segments of the Valu Fa...
