NOAA TECHNICAL MEMORANDA 



National Ocean Survey Series 



The National Ocean Survey (NOS) provides charts and related information for the safe navigation of 

 marine and air commerce. The survey also furnishes other Earth science data--from geodetic, hydro- 

 graphic, oceanographic, geomagnetic, seismologic, gravimetric, and astronomic surveys or observations, 

 investigations, and measurements—to protect life and property and to meet the needs of engineering, 

 scientific, commercial, industrial, and defense interests. 



NOAA Technical Memoranda NOS series facilitate rapid distribution of material that may be preliminary 

 in nature and which may be published formally elsewhere at a later date. Publications 1 through 8 are 

 in the former series, ESSA Technical Memoranda, Coast and Geodetic Survey Technical Memoranda (CSGSTM) . 

 Beginning with 9, publications are now part of the series, NOAA Technical Memoranda NOS. 



Publications listed below are available from the National Technical Information Service (NTIS) , U.S. 

 Department of Commerce, Sills Bldg., 5285 Port Royal Road, Springfield, Va. 22151. Price varies for 

 paper copy; $1.45 microfiche. Order by accession number (in parentheses) when given.
