Creator:: Mazzini, Piero L. F., Risien, Craig M., Barth, John A., Pierce, Stephen D., Erofeev, Anatoli, Dever, Edward P., Kosro, P. Michael, Levine, Murray D., Shearman, R. Kipp, and Vardaro, Michael F.
Abstract:: From mid-May to August 2011, extreme runoff in the Columbia River ranged from 14,000 to over 17,000 m³/s, more than two standard deviations above the mean for this period. The extreme runoff was the direct result of both melting of anomalously high snowpack and rainfall associated with the 2010–2011 La Niña....

Abstract:: During fall/winter off the Oregon coast, oceanographic surveys are relatively scarce because of rough weather conditions. This challenge has been overcome by the use of autonomous underwater gliders deployed along the Newport hydrographic line (NH-Line) nearly continuously since 2006. The discharge from the coastal rivers between northern California and the...

Abstract:: Climate models predict a decrease in oceanic dissolved oxygen and a thickening of the oxygen minimum zone, associated with global warming. Comprehensive observational analyses of oxygen decline are challenging, given generally sparse historical data. The Newport hydrographic (NH) line off central Oregon is one of the few locations in the...

Abstract:: A high-resolution upper-ocean survey of a cyclonic jet meander and an adjacent cyclonic eddy in the California Current region near 38°N, 126°W was conducted as part of the summer of 1993 Eastern Boundary Currents program. Temperature and salinity were measured from a SeaSoar vehicle, and velocity was measured by shipboard...

Abstract:: Several diagnoses of three-dimensional circulation, using density and velocity data from a high-resolution, upper-ocean SeaSoar and acoustic Doppler current profiler (ADCP) survey of a cyclonic jet meander and adjacent cyclonic eddy containing high Rossby number flow, are compared. The Q-vector form of the quasigeostrophic omega equation, two omega equations derived...

Abstract:: High concentrations of chlorophyll are found in the California Current System over 300 km offshore, far from the productive coastal upwelling region, and between 150 and 250 m, well below the depth to which photosynthetically active solar radiation penetrates. This exceptionally deep chlorophyll feature is formed near the coast and...

Abstract:: This report summarizes the Seasoar and CTD observations from Wecoma cruises W9306A (5 June to 12 July, 1993) and W9308B (14 August to 22 September 1993) conducted as part of the Eastern Boundary Currents Accelerated Research Initiative, under funding by the Office of Naval Research. The cruises were designed to...
