Satellite observations of the inﬂuence of mesoscale ocean eddies on near-surface temperature, phytoplankton and surface stress

Creator:: Gaube, Peter
Abstract:: The influence of mesoscale ocean eddies on near-surface ocean temperature, surface stress and phytoplankton communities is investigated by collocating numerous satellite measurements along with vertical profiles of oceanic temperature and salinity to the interiors of eddies identified and tracked in altimetric sea surface height maps. The surface currents associated with...

Ensemble-variational data assimilation for dynamically challenging coastal ocean circulation

Creator:: Pasmans, Ivo
Abstract:: Currently, forecasts produced by the Oregon-Washington (OR-WA) Coastal Ocean Forecast System are constrained by assimilation of only surface observations. The 4-dimensional variational (4DVAR) data assimilation (DA) algorithm is utilized to combine the model and the data, with the time-independent forecast ("background'') error covariance B. In this study, two possible improvements...

Optics, structure and variability of the offshore Columbia River plume

Creator:: Saldías, Gonzalo
Abstract:: The Columbia River delivers the greatest amount of freshwater to the coastal ocean along the U.S. Pacific coast. This freshwater forms the Columbia River plume, a mesoscale plume with significant implications on coastal ocean physical, biological, chemical, and geological processes. The plume is transported south and offshore during the upwelling...

Vertical Coastal Trapped Wave Propagation Produced by a Subsurface Ridge

Creator:: Dhage, Laxmikant
Abstract:: The vertical propagation of Coastal Trapped Waves (CTWs) due to subsurface ridges is explored with the help of linear numerical and analytical models. Results show that submerged ridges projecting from the shoreline can scatter a horizontally propagating single baroclinic mode Kelvin wave into both upward and downward propagating Kelvin wave...

Intra-seasonal sea level variability along the west coast of India

Creator:: Dhage, Laxmikant
Abstract:: The importance of local versus distant forcing is studied for the wind driven intra- seasonal (30-120 day) sea level anomaly (SLA) variations along the west coast of India. Three locations on the continental slope are chosen to represent the west coast. Two more locations, one east of Sri-Lanka and another...

Wind-current Interactions of the Sri Lanka Dome and Tropical Indian Ocean

Creator:: Cullen, Kerstin
Abstract:: The southwest monsoon, which may be idealized as the northward movement of the intertropical convergence zone in the Indian Ocean associated with differential heating of land and ocean, brings a seasonal reversal of currents and winds in the Bay of Bengal and the Arabian Sea. Atmospheric convection from monsoon activity...

Providing the best turbulent heat flux estimates from eddy correlation and bulk methods using DYNAMO data

Creator:: Marion, June Raven
Abstract:: In this thesis, data collected during the Dynamics of the Madden Julian Oscillation (DYNAMO) field campaign, conducted in the Indian Ocean in Fall of 2011, is used to compute heat fluxes at the air-sea interface by evaluating eddy covariances and bulk aerodynamic formulae. Errors in daily average gridded fluxes computed...

The effect of river discharge and wind forcing on the Oregon coastal ocean during fall and winter

Creator:: Mazzini, Piero Luigi Fernandes
Abstract:: Freshwater provided from river discharge influences the dynamics and circulation of most continental shelves around the world. It has profound effects on the transport and fate of materials and substances originated from rivers and estuaries, as well as on the ocean biogeochemistry and marine ecosystems. The effect of buoyancy forcing...

Oregon climate assessment report : December 2010

Creator:: Dello, Kathie D., Mote, Philip W., and Oregon Climate Change Research Institute
Abstract:: The group of scientists that make up the Intergovernmental Panel on Climate Change found in 2007 that the warming of Earth’s climate is unequivocal and largely due to human activity. Earth’s climate has changed in the past, though the recent magnitude and pace of changes are unprecedented in human existence....
