A shirtsleeve test of geologic reconnaissance methods applicable to lunar surface exploration was conducted using astronauts as subjects. The task analysis objective was to determine the efficiency of a 2-man traverse. A table summarizes the full-day traverse, and a process chart (time line) is included in the report. It was concluded that two astronauts can complement each other's work...

Systems and shirt-sleeve operations tests were conducted at the Bonito Flow test site from April 5 through April 9. The tests provided the opportunity to evaluate field test logistics, systems compatibility, systems operation, and geological field and control center operations. This report summarizes the evaluations that bear on the potential usefulness of systems and operations.

Apollo Applications Program (AAP) Test 3 was held in Flagstaff, Arizona, as an initial feasibility study of rock thin-section preparation and remote television monitoring of the microscopic image, for possible use on AAP missions. During the 18 hours of actual test operations 38 thin sections were prepared. Of these, 25 were examined with a petrographic microscope with a television link...

At the suggestion of the Planetology Subcommittee of the Space Sciences Steering Committee, an active engineering seismic experiment originally proposed by J. S. Watkins, J. Cl. De Bremaecker, and M. F. Kane was incorporated into the Early Apollo Active Seismic Experiment originally proposed by R. L. Kovach . J. S. Watkins was made co-experimenter for the Early Apollo Active Seismic...

The National Aeronautics and Space Administration plans to land two astronauts on the Moon as a part of the Apollo Space Program. The questions arise: What should the astronauts do on the surface and what information should they gather? This report proposes answers to these questions by describing a possible series of scientific activities, or mission profiles, to be performed by the...

A field test held in the Hopi Buttes, Arizona, was planned to test geological, geophysical, and analytical operations and instruments that are of potential use in Apollo Extension Systems lunar surface missions. The test was conducted under "shirt-sleeve" conditions, but potentially useful methods of recording and compiling information during lunar exploration were employed. The test...

When the Apollo astronauts land on the Moon, their precise location will not be known. The real-time geologic mapping planned for the first mission could best be done if the exact position of the landing site were determined. The astronauts may have to find their position, with or without assistance from the Earth-based scientific mission center, before leaving the Lunar Module (LM), and...

In several respects the Nevada Test Site is located in an area that is especially interesting geologically. It lies along the projected trend of the Walker Lane and the Las Vegas Valley Shear Zone (Locke and others, 1940; Longwell, 1960), one of the major crustal features of the Basin-Range province. The shear zone itself, however, may not continue through the Test Site in a simple way...

These suggestions are largely a result of two closely allied factors: first, a tape recording--either direct or one made via radio--should enable· a field geologist to record many more observations per unit time than can be made in a notebook. The observations should be to the point, but there is no reason for them to be cryptic and so potentially ambiguous to another person. Second...

This digital map database provides an areally continuous representation of the Quaternary surficial deposits of the San Francisco Bay region merged from the database files from Knudsen and others (2000) and Witter and others (2006). The more detailed mapping by Witter and others (2006) of the inner part of the region (compiled at a scale of 1:24,000), is given precedence over the less...

Bathymetric LiDAR technology was used to collect riverbed elevation data along the Potomac River. In support of this effort, a bathymetric survey with a boat-mounted acoustic Doppler current profiler (ADCP) was conducted in the study area during October 4-7, 2021. The study area consisted of four verification reaches on the Potomac River including: 1) Williamsport accessed through the...

The study is comprised of daily survey data consisting of high resolution mapping and discrete sample collection of nutrients, phytoplankton, and related water quality constituents conducted in the Sacramento River, Georgiana Slough, and the North and South Forks of the Mokelumne River on August 28 and September 10-12, 2019, coincident with planned holds of treated wastewater effluent...
