摘要:
In the coming decades, the Earth and ocean science communities will address global problems using new, large‐scale, long‐term monitoring systems distributed around the planet. Such measurements will be needed to better understand geophysical processes that vary on time scales of months to decades; they will also provide “ground truth” for observations derived from satellites. However, achieving broad spatial coverage within the oceans using conventional instrumentation deployed from ships will be very costly, and real‐time data telemetry from seafloor‐based instrumentation poses many technical challenges. A complementary approach might utilize portions of the worldwide system of transoceanic analog telecommunications cables; these are due to retire from commercial service over the next decade as they are replaced by fiber optic technology.Walker[1991], for example, discusses submarine cable usage in the context of global chan

摘要:
The Magellan Project appreciates David Morrison's reminder that our vertically exaggerated (22.5 times) images and videos are produced by combining images with altimetry, a fact that we try to point out on both videos and images released to the public. The computer‐generated scenes are produced as part of a solar system visualization project that combines various data sets for scientific computer visualization and analysis. We felt that the images would be of interest to others. Part of the reason that we use vertical exaggeration is that we are trying to show topographic variations over very large areas, the scale at which we have accurate topographic information. (There is a disparity between the 120–300 m resolution of the images and the greater than 10 km resolution of the topograp
