CryoSat-2 carries a sophisticated radar altimeter to meet two principal challenges. The first is to acquire accurate measurements of the thickness of floating sea ice so that annual variations can be detected. The second is to survey the surface of ice sheets accurately enough to detect small changes. CryoSat-2's radar altimeter is based on heritage from existing instruments, but with several majo

Data and images displayed on STAR sites are provided for experimental use only and are not official operational NOAA products. More information>> An altimeter measures how high something is. Satellite radar altimeters measure the ocean surface height (sea level) by measuring the time it takes a radar pulse to make a round-trip from the satellite to the sea surface and back. Bathymetry is measureme

Basics of Space Flight: Orbital Mechanics
Satellite orbits can be any of the four conic sections. This page deals mostly with elliptical orbits, though we conclude with an examination of the hyperbolic orbit. Orbital Elements To mathematically describe an orbit one must define six quantities, called orbital elements. They are Semi-Major Axis, a Eccentricity, e Inclination, i Argument of Periapsis, Time of Periapsis Passage, T Longitude of

Oceanic Plateaus
Oceanic plateaus are vast areas (> 0.1 × 106 km2) of overthickened oceanic crust (up to, and sometimes > 30 km) that are widely interpreted to have formed by decompression melting of hot mantle plumes. Oceanic plateaus have formed throughout most of Earth's history and, due to their excess crustal thicknesses, are difficult to subduct; typically, their uppermost sections are accreted to continenta
Lynch, Guide to Grammar and Style
Note: I've been working on a new guide that might help some readers of this one, called “Getting an A on an English Paper.” It's far from finished, but it may still be useful. I've also been experimenting with a new search engine. It's very rudimentary, but may be useful. Introduction These notes are a miscellany of grammatical rules and explanations, comments on style, and suggestions on usage I
