 NATIONAL AERONAUTICS AND SPACE ADMINISTRATION, "Earth Photographs from 

 Gemini III, IV, and V," NASA Special PubUcation 129, Office of Technology 

 Utilization, National Aeronautics and Space Administration, Washington, D. C, 1967. 



Keywords: Satellite Photographs, Coastal Processes, Oceanographic Applications 



Publication presents 244 color satellite photos from the Gemini III, IV, and V missions. The 

 photos are enlarements of film taken with a handheld Hasselblad 70-mm camera. About 25 

 percent of the photos show coastal features and processes. A description of the area covered 

 and the features in each photo are included. Littoral currents, sediment patterns, and 

 variable water depths are visible on satelhte photos. The photos can be used to illustrate 

 coastal features and processes from sateUite altitudes and to investigate their potential 

 coastal engineering and oceanographic applications. An index of Gemini III, IV, and V 

 satellite photos and a geographic index are included.

D. C, Feb. 1967. 



Keywords: Aerial Remote Sensors, Bibliography, Oceanographic Applications 



Bibliography covers a wide range of topics related to oceanography and remote sensing. It 

 was prepared to collect scattered references in a practical form for investigators in spacecraft 

 (and aircraft) oceanography. Bibliography is divided into five major categories, including 

 oceanography background information, surface phenomena, observations by remote sensors, 

 economic benefits of remote sensors in oceanography exploration, and unpublished reports. 

 Section on remote sensors is subdivided by type and includes photo sensors, infrared 

 sensors, radar sensors, microwave sensors, and lasers and masters. About 600 references are 

 listed in the bibliography.

Mouth 

 Article describes a study of surface currents near the mouth of the Columbia River by use of 

 color photos. Color photos were taken of floating targets consisting of color-coded, vinyl air 

 mattresses dropped from a boat. Photos were taken during flood tide and ebb tide. Targets 

 were distributed at about 1/2-mile intervals across the river mouth and surrounding area. 

 The mattresses were filled with water to prevent wind interference. Ground control was 

 provided by anchored navigational buoys and adjacent landforms. Surface current 

 trajectories and velocities were determined by comparing the position of targets on photos 

 taken during successive flights with a known time lapse, although details of target movement 

 measurement procedure are not given. Procedure was concluded to give satisfactory results 

 and advantageous for dynamic surface current patterns over a large area.
