The sensitivity of sea ice to the contrasting seasonal and perennial snow properties in southeastern northwestern Weddell Sea is not yet considered model satellite remote sensing applications. However, analysis physical snowpack late summer recent years reveals a high fraction melt-freeze forms resulting significant higher densities than eastern Sea. lower thermal conductivity snowpack, which o...

Global illumination researchers tend to think in terms of mesh density and sampling frequency, and their software reflects this in its user interface. Advanced rendering systems are rife with long command lines and parameters for tuning the sample densities, thresholds and other algorithm-specific variables, and the novice user is quickly lost in a sea of possibilities. This paper details a suc...

Observations of the atmospheric sources and sinks carbon dioxide (CO2) methane (CH4) in pan-Arctic domain are extremely scarce, limiting our knowledge turnover this climatically sensitive environment fate enormous reservoirs conserved permafrost. Especially critical gaps high latitudes Siberia, covered by vast permafrost underlain tundra, where only several monitoring sites operational. This pa...

This paper will outline the technical challenges of dynamic interface modelling & simulation, with a specific example of the Joint Shipboard Helicopter Integration Process (JSHIP). This program, one of the most ambitious helicopter simulation programs undertaken to date, has helped both to understand the potential of rotorcraft simulation today, and to realize the limitations of technology. The...

Drawing on examples mostly from Inupiaq and Yupik sea ice expertise in coastal Alaska, this contribution examines how local and indigenous knowledge (LIK) can inform and guide geophysical and biological sea ice research. Part of the relevance of LIK derives from its linkage to sea ice use and the services coastal communities derive from the ice cover. As a result, indigenous experts keep track ...

The association of Antarctic krill Euphausia superba with the under-ice habitat was investigated in the Lazarev Sea (Southern Ocean) during austral summer, autumn and winter. Data were obtained using novel Surface and Under Ice Trawls (SUIT), which sampled the 0-2 m surface layer both under sea ice and in open water. Average surface layer densities ranged between 0.8 individuals m(-2) in summer...

copper–silver bimetallic strips were produced by cold roll welding process and were treated by diffusion annealing in the temperature range 250–800 ?c. the interface bonding strength was determined by bending and peeling tests, resistance, conductivity and micro hardness profiles were determined and microstructure in the interface region was observed by optical microscope. electrical resistance...

Toxoplasma gondii affects a wide variety of hosts including threatened southern sea otters (Enhydra lutris nereis) which serve as sentinels for the detection of the parasite's transmission into marine ecosystems. Toxoplasmosis is a major cause of mortality and contributor to the slow rate of population recovery for southern sea otters in California. An updated seroprevalence analysis showed tha...
