Spring floods carry Alaskan river water north to a frozen Beaufort Sea. A plume of water from the Sagavanirktok River (SR) was identified and traced by measuring salinity, d18O, and dissolved silica in discrete water samples collected beneath landfast ice in the coastal Alaskan Beaufort Sea from late May to early June 2004 during high river flow. An Optimum Multiparameter analysis was used to calculate the fractions of SR water from the measured geochemical parameters. The SR plume followed the northwestward flowing local circulation and moved ~17 km north and ~15 km west under ice from the river mouth. The …

The Lazarus and Bewley [2005] (hereinafter referred to as LB05) evaluation of the Archer and Jacobson [2003] (hereinafter referred to as AJ03) methodology was designed to examine various sensitivities of a wind power parameterization that was applied globally to estimate 80-m wind power. AJ03 has since been updated in a sequence of papers which has, in part, resulted in a reduction of their original power estimates due to some changes in their basic equations. The motivation for the LB05 work can be found in AJ03’s Figure 3 which indicates annual wind power estimates of class 6 and 7 effectively collocated …

Voyagers 1 and 2 observed highly-variable beams of energetic ions in the foreshock region upstream of the termination shock (TS). At Voyager 2 (V2), the ion intensities are generally not related to the plasma properties. At Voyager 1 (V1), the beams are often coincident with crossings of the heliospheric current sheet (HCS). The V1 intensity peaks occur when the HCS is crossed from negative to positive magnetic polarities and V1 is within a few AU of the TS. Two mechanisms are considered: current sheet drift and streaming of ions from the TS along magnetic field lines which are parallel to …
