and compared with concurrent temperature and 
salinity data. 
Although deep ocean currents are generally of 
low velocity, some evidence exists that these 
currents coupled with the presence of a structure 
could create turbulence, erode the bottom, pro- 
duce a wake of turbid water, and affect founda- 
tion stability. These effects could make a bottom 
installation more detectable by acoustic means and 
could upset or bury the structure; therefore, 
further investigation of near-bottom currents is a 
necessity. 
f. Hydrospace Handbook At present the ocean 
engineer has no single source of information 
summarizing data on environmental factors and 
their effects on materials and components consid- 
ered in designing ocean systems. The U.S. Air 
Force prepared the Handbook of Geophysics and 
Aerospace Materials Handbooks to provide infor- 
mation for design of aircraft, missiles, and space- 
craft. A hydrospace handbook containing informa- 
tion on environmental factors affecting ocean 
engineering design could be invaluable. One such 
handbook is expected to be released in the near 
future. 
An important function of both industry and 
government will be to assure that such handbooks 
are continuously updated and technical memo- 
randa, failure analyses, and engineering data to 
help advance ocean capability are published. An- 
other responsibility is in preparing ocean engineer- 
ing texts for teaching and technical reference.
