Acoustic-reflection profiles, Bay of Campeche: International Decade of Ocean Exploration, U.S. Geological Survey, Leg 1, 1971 cruise, UNITEDGEO I
IntroductionAs part of a cooperative marine research program designated the International Decade of Ocean Exploration (IDOE), the United States Geological Survey is participating in an investigation of the geologic framework and resource potential of continental margins and small ocean basins in the Gulf of Mexico, Caribbean Sea, and west African continental shelf areas. These studies are funded t

Interstitial water studies on small core samples, Leg 9
The chemistry of the pore fluids obtained on Leg 9 is remarkable primarily in its constancy. Excepting silicon and strontium, only at one site do the concentrations of the major and minor constituents deviate notably from sea water concentrations (see Tables 1 and 2). The trends, or lack of them, seen in these samples have been discussed previously and only references will be given here. The const

Photogrammetry and altimetry: Part C: frequency distributions of lunar slopes
The metric and panoramic cameras aboard the Apollo 16 spacecraft provided photographs on which photogrammetric techniques may be used to obtain precise measurements of horizontal distances and elevations. These measurements of horizontal distances and elevations. These measurements may in turn be used to obtain slope-frequency distributions of lunar surfaces at various slope lengths and for variou

Photogrammetry and altimetry: Part B: photogrammetry using Apollo 16 orbital photography
The Apollo 15 and 16 metric and panoramic cameras have provided photographs for accurate topographic portrayal of the lunar surface using photogrammetric methods. In turn, quantitative morphologic analyses of topographic results are invaluable aids in the interpretation of the geologic processes.

Photogeology: Part Y: physical and geological aspects of heiligenschein measurements
Heiligenschein is the upsurge in reflected brightness as zero-phase angle is approached. For the first time, an effort has been made to investigate the diagnostic value of the heiligenschein photometric magnitude on a statistically significant scale. This investigation was performed by using the vertical photography of the Apollo 16 metric camera. The brightness surge of reflected light near zero-

Photogeology: Part W: Apollo 16 landing site: summary of Earth-based remote sensing data
The purpose of the infrared (IR) and radar study of the Apollo data is to establish lunar surface conditions in the vicinity of the orbital tracks of the Apollo command modules during the J-series missions. Correlations and comparisons between the Earth-based radar observations, IR observations, and other data will be plotted on photomaps produced from the mapping and panoramic cameras. In additio

Photogeology: Part S: mare ridges and arches in southern Oceanus Procellarum
Low-relief mare features such as ridges and arches are best studied by using stereoscopic photographs taken at low Sun angles. Apollo 16 metric camera photography of the southern Oceanus Procellarum east of Letronne Crater reveals a diversity of subtle features (fig. 29-125) and adds significantly to an understanding of the forms of mare ridges and arches their relative ages, and their association

Photogeology: Part X: calibration of radar data from Apollo 16 results
Orbital and surface photography collected during the Apollo 16 mission can be used to calibrate existing Earth-based, high-resolution radar maps of the lunar surface. The absence of any theoretical treatment of the radar backscatter from irregular rocks has prevented the assignment of radar-echo cross sections to specific size distributions of rocks. This gap will now be filled with the use of gro

Photogeology: Part N: ejecta blankets of large craters exemplified by King Crater
Details of the ejecta blankets of large, fresh craters provide insight into the mechanics of deposition and the sequence of emplacement of impact debris. King Crater is the freshest of the three large, rayed craters photographed from Apollo 16; the others are Theophilus and Langrenus Craters. King Crater is comparable in youth to Tycho Crater, and the details of its ejecta blanket help to interpre

Photogeology: Part L: crater morphometry
Morphometric analysis of lunar craters (ref. 29-75) complements the more traditional photointerpretive study of crater morphology. These two indirect approaches to the scientific investigation of lunar craters continue to be productive because the preferred alternative method, direct field examination of specific large craters, is not being undertaken in the current series of manned lunar landings
