Longitude from Moon Culminations

Latitude and longitude vertical disparities.

The literature on vertical disparity is complicated by the fact that several different definitions of the term "vertical disparity" are in common use, often without a clear statement about which is intended or a widespread appreciation of the properties of the different definitions. Here, we examine two definitions of retinal vertical disparity: elevation-latitude and elevation-longitude dispar...

Animal Navigation: Longitude at Last

Newly hatched sea turtles exposed to artificially generated magnetic fields with parameters characteristic of two sites 3700 km apart, differing only in longitude, can distinguish the two apparent locations and orient appropriately.

Animal Navigation: The Longitude Problem

Determining longitude is incredibly difficult--for humans. Are animals fooling us into thinking that they have bicoordinate maps? New experiments show that at least some creatures effortlessly solve the seemingly insoluble problem of longitude.

Thermal Infrared Data from the Moon: Hazards

Introduction: Earth’s relatively clear thermal infrared (TIR) atmospheric windows correspond to the wavelength region of maximum emitted energy for the global average temperature (8-12 μm) as well as the temperature of most volcanoes/fires (3-5 μm). Furthermore, a majority of minerals have diagnostic emissivity spectra in the 8-12 μm region, making it excellent for the study of surface composit...
