“…8a, b) Hence, magnitudes of the mean barotropic and baroclinic transports are comparable at MS, while the mean baroclinic transport at HE is about four times larger than at MS and, thus, about five times larger than the mean barotropic transport at HE. Moreover, comparison of the baroclinic transports through each layer indicates that inflow through one layer at HE is not balanced by outflow through the corresponding layer at MS; hence, significant vertical transport/mixing is expected inside the Sound, as confirmed in a previous study (Bang and Mooers 2003). Therefore, strong baroclinic flows through each layer are anticipated to have significant effects on the circulation in PWS.…”

“…Previous numerical studies have indicated the importance of horizontal as well as vertical flow structure at HE and MS, with implications for the circulation pattern in the Central Sound and elsewhere in PWS (Bang and Mooers 2003;Bang et al 2005). Since a sustained observing system from surface to bottom and across the entire cross section at HE and MS is not available for determining flow and mass fields, volume and heat transports, etc., the present EPWS/NFS run provides a useful proxy and a unique opportunity to investigate how volume transports through the two straits are related to each other and what role(s) these two straits play in affecting the variability of circulation patterns inside PWS.…”

Using 1-year simulated data from extended Prince William Sound (PWS) nowcast/forecast system, both barotropic and baroclinic transports through twostrait, semi-enclosed PWS are examined. With major tidal constituents removed, hourly time series of volume transports through two straits are significantly correlated with net transport well balanced by the time rate of change of the PWS spatial-mean sea level. A transition frequency band occurs within the coherence function of hourly volume transports, which is characterized by a nearly 180 • phase shift between lowfrequency (>30 h) and high-frequency (<6 h) bands. The transition band is implicitly related to the horizontally divergent and horizontally non-divergent flows inside the Sound. Further investigation of monthly and annual mean volume transports indicates strong seasonal variability of flows through two straits. On the other hand, baroclinic transport through PWS demonstrates the transition between a two-layered flow structure during the wintertime and a well-defined three-layered structure, i.e., inflow in both the surface and bottom layer with outflow in the intermediate layer, in the remainder of the year. This three-layer exchange flow is determined to be mainly buoyancy-driven, geostrophic flow, and thus largely affected by seasonal variability of buoyancy over the shelf and PWS.

“…Our measurements are in agreement with the seawater salinity at PWS found in literature. The reported PWS salinity values vary between 33.00 g L −1 in the middle of the sound to 20.00 g L −1 close to the shorelines, which receives freshwater run off (Gay and Vaughan 2001;Vaughan et al 2001;Bang and Mooers 2003;Li and Boufadel 2010). The ANOVA analysis showed that the salinities within the beach were significantly different from each other.…”

Knowledge of the oxygen and nutrient concentrations in an oil-contaminated Prince William Sound (PWS) beach is important for understanding of the oil persistence over two decades after the Exxon Valdez spill. It was traditionally believed that there was enough oxygen in the contaminated shorelines to sustain aerobic microbial metabolism of oil and that nutrients were the major factors limiting oil biodegradation. In the present study, we analyzed the oxygen and nutrients levels in both clean and oily areas on a PWS beach that was heavily contaminated by the Exxon Valdez oil spill. We found that the level of nitrogen and phosphorous were 0.454 mg-N L −1 and 0.033 mg-P L −1 , respectively, which is not sufficient to fully support microbial growth, confirming that nutrient concentration was a major factor limiting oil transformation by biological ways. We also observed that the oxygen level varied from higher than 3 mg L −1 in the clean wells to about 1 mg L −1 (near anoxic level) in the oily wells. In addition, the lowest nitrate levels were observed at the oily wells. Altogether, these results suggest that the low level of efficient electron acceptors (oxygen and nitrate) detected at the oily spot is responsible for slow and potentially inefficient biodegradation of the oil.

“…There were also talks on internal waves and the stability of models, and it was something of a coup to get permission to publish in the Journal of Physical Oceanography. One paper, by Bang and Mooers (2003), outlined a model of Prince William Sound and another, by Luyten et al (2003), the traditional area of the North Sea. This shows that specificarea models only were published in the Journal of Physical Oceanography, which was a shame and failed to reflect the breadth of papers presented at the conference itself.…”
