The Trans-Alaska Pipeline System: A Systems Engineering Case Study
The Trans-Alaska Pipeline System (TAPS) was constructed between 1974 and 1977 in response to the 1973 oil crisis. It conveys oil from Prudhoe Bay in northern Alaska to the port of Valdez in the southeast, a distance of over 800 miles (1,300 km). Building the pipeline system meant dealing with a multiplicity of complex design and management decisions that involved engineering, environmental, pol...
متن کاملMethane: signs of progress along the road.
Analyses of air bubbles within ice cores suggest that the concentration of atmospheric methane remained fairly steady from 1500 BC to 1700 AD. However, with the dawn of the Industrial Revolution atmospheric methane concentrations began to increase. Recent findings of Simpson et al. (2006) have shown that the growth in the concentration of tropospheric methane has leveled off based on air sampli...
متن کاملSimulating vegetation processes along the Kalahari transect
The Sheffield Dynamic Global Vegetation Model has simulated the structure and net carbon exchange of vegetation at five sites along the Kalahari transect where there is a strong gradient in precipitation from 299 to 918mmyr . There has been a decline in precipitation of 8mmyr 1 along the whole of the transect since about 1970. Simulations of vegetation dynamics and structure indicate that this ...
متن کاملMajor solutes, metals, and alkylated aromatic compounds in high-latitude maritime snowpacks near the trans-Alaska pipeline terminal, Valdez, Alaska
The chemical constituents within a snowpack can provide information about the atmosphere through which the snow was deposited. Valdez is located in south-central Alaska and has a high-latitude maritime climate, with annual snowfall typically exceeding 8 m within the city limits. Valdez is also the termination point of the trans-Alaska pipeline system, where tankers are loaded with crude oil fro...
متن کاملTrends in spatial patterns of heavy metal deposition on national park service lands along the Red Dog Mine haul road, Alaska, 2001–2006
Spatial patterns of Zn, Pb and Cd deposition in Cape Krusenstern National Monument (CAKR), Alaska, adjacent to the Red Dog Mine haul road, were characterized in 2001 and 2006 using Hylocomium moss tissue as a biomonitor. Elevated concentrations of Cd, Pb, and Zn in moss tissue decreased logarithmically away from the haul road and the marine port. The metals concentrations in the two years were ...
