bottom mapping at three sites along the Florida Straits. Sites investigated were the Bahama 

 Banks south of Bimini, the southern half of Biscay ne Bay, and the central Florida Keys. 

 Submerged features and important relationships between vegetation and bottom conditions 

 identified on the photos are described. The bottom was mapped from vegetation type. 

 Manmade features, water pollution and their ecological effects were interpreted from the 

 photos. Color photos are a useful tool in coastal ecological surveys.

Paper describes the results obtained by tlie U.S. Naval Oceanographic Office in two tests of 

 water penetration capability of color film. The tests were to develop techniques for 

 improving water penetration by color film for use in charting nearshore bottom detail and 

 measuring water depths. One test in 1967 off the Florida Keys was an analysis of color 

 photos taken at different altitudes of gray scale and color targets placed on land and 

 underwater. Test showed that blue light hmited depth penetration, but green light gave the 

 greatest penetration. A new color film (Anscochrome SS48895), produced by the GAF 

 Corporation, omits the blue-sensitive emulsion layer. This film, using various filters, was 

 tested in 1968 at Andros Island, Bahamas. The film was capable of water penetration to 150 

 feet with good image contrast. Detailed bottom features and depth penetration was 

 obtained from photos exposed with the 560 millimicron part of the spectrum.

Article presents the coastal mapping program of the USC&GS (now the National Ocean 

 Survey). Importance of mapping in the development of the coastal zone is emphasized. The 

 need for accurately locating the coastline to establish the offshore boundaries that define 

 state and federal ownership is noted. The role of pliotogrammetry in coastal mapping is 

 described. Use of black and wliite photos in delineating the waterline at tidal stages is also 

 noted. Difficulty in defining the shoreline in marshes and swamps is discussed. Coastal 

 mapping programs by USC&GS with state support in Louisiana and Florida are described.
