RISTemporal Variability of the Energy Balance of Thick Arctic Pack Ice
Publisher: American Meteorological Society
Abstract: The temporal variability of the six terms of the energy balance equation for a slab of ice 3 m thick is calculated based on 45 yr of surface meteorological observations from the drifting ice stations of the former Soviet ...
The Thinning of Arctic Sea Ice, 1988–2003: Have We Passed a Tipping Point?
Publisher: American Meteorological Society
Abstract: Recent observations of summer Arctic sea ice over the satellite era show that record or near-record lows for the ice extent occurred in the years 2002?05. To determine the physical processes contributing to these changes ...
Assimilation of Ice Concentration in an Ice–Ocean Model
Publisher: American Meteorological Society
Abstract: Ice concentration is a critical parameter of the polar marine environment because of the large effect sea ice has on the surface albedo and heat exchange between the atmosphere and the ocean. Simulations of the energy ...
Arctic Ocean Ice Thickness: Modes of Variability and the Best Locations from Which to Monitor Them
Publisher: American Meteorological Society
Abstract: Model simulations of Arctic sea ice and ocean systems are used to determine the major spatial and temporal modes of variability in the ice thickness. A coupled ice?ocean model is forced with daily NCEP?NCAR reanalysis ...
Statistical Sampling for In-Service Inspection of Underground Storage Tanks (PVP2011-57011)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Savannah River Remediation, LLC (SRR) is implementing a statistical sampling strategy for in-service inspection (ISI) of liquid waste (LW) tanks at the United States Department of Energy’s Savannah ...
A New Lagrangian Model of Arctic Sea Ice
Publisher: American Meteorological Society
Abstract: A new Lagrangian sea ice model for the Arctic Ocean has been developed to accommodate the assimilation of integral measures of ice displacement over periods of days or weeks. The model is a two-layer (thick ice and open ...
The RADARSAT Geophysical Processor System: Quality of Sea Ice Trajectory and Deformation Estimates
Publisher: American Meteorological Society
Abstract: NASA's RADARSAT Geophysical Processor System (RGPS) uses sequential synthetic aperture radar (SAR) images to track the trajectories of some 30 000 points on the Arctic sea ice for periods of up to 6 months. Much of the ...
Arctic Sea Ice Surface Temperature from AVHRR
Publisher: American Meteorological Society
Abstract: The surface temperature of arctic sea ice is estimated using the infrared channels of the Advanced Very High Revolution Radiometer (AVHRR) on satellites NOAA-10 and NOAA-11. Temperature statistics are analyzed for 478 cells ...
Arctic Sea Ice Albedo from AVHRR
Publisher: American Meteorological Society
Abstract: The seasonal cycle of surface albedo of sea ice in the Arctic is estimated from measurements made with the Advanced Very High Resolution Radiometer (AVHRR) on the polar-orbiting satellites NOAA-10 and NOAA-11. The albedos ...
Energy Harvesting From Vibrations With a Nonlinear Oscillator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a nonlinear electromagnetic energy harvesting device that has a broadly resonant response. The nonlinearity is generated by a particular arrangement of magnets in ...
