This text file contains an overview of the files available on this data disk. Report title: Observations of the Surge-Type Black Rapids Glacier, Alaska, During a Quiescent Period, 1970-92 by TA Heinrichs, LR Mayo, DC Trabant, and RS March, 1995 US Geological Survey Open File Report 94-512 For additional information write to: District Chief US Geological Survey 4230 University Drive, Suite 201 Anchorage, Alaska, 99508-4664 This disk contains the mass balance, ice velocity, surface altitude, and ice thickness data tables. It is a 3.5-inch, 1.44 megabyte disk formatted with IBM PC operating system MS-DOS 6.0. Data tables are written to it in two formats: ASCII text and Lotus 123 version 2.01 .WK1 spreadsheet format. The ASCII files are in a subdirectory named "ASCII" and the Lotus 123 files are in a subdirectory named "LOTUS123". The following tables are on this disk. Listed below are the Lotus 123 file names with .WK1 extension. The ASCII text files have the same names, except the file name extension is .TXT. For example, Table 1 is TABLE1.TXT Table # File name Table description ------- --------- ------------------------------- 1 TABLE1.WK1 Net mass balance (summary) 9A TABLE9A.WK1 Ice velocity data 2 km site 9B TABLE9B.WK1 Ice velocity data 4 km site 9C TABLE9C.WK1 Ice velocity data 8 km site 9D TABLE9D.WK1 Ice velocity data 14 km site 9E TABLE9E.WK1 Ice velocity data 20 km site 9F TABLE9F.WK1 Ice velocity data 26 km site 9G TABLE9G.WK1 Ice velocity data 32 km site 9H TABLE9H.WK1 Ice velocity data 38 km site 9I TABLE9I.WK1 Ice velocity data L-19 km site 9J TABLE9J.WK1 Ice velocity data L-22 km site 10 TABLE10.WK1 Additional ice velocity measurements 11 TABLE11.WK1 Longitudinal velocity profile (7/73 to 7/74) 12 TABLE12.WK1 Velocity cross-profiles 14A TABLE14A.WK1 Surface altitude 2 km site 14B TABLE14B.WK1 Surface altitude 4 km site 14C TABLE14C.WK1 Surface altitude 8 km site 14D TABLE14D.WK1 Surface altitude 14 km site 14E TABLE14E.WK1 Surface altitude 20 km site 14F TABLE14F.WK1 Surface altitude 26 km site 14G TABLE14G.WK1 Surface altitude 32 km site 14H TABLE14H.WK1 Surface altitude 38 km site 14I TABLE14I.WK1 Surface altitude L-19 km site 14J TABLE14J.WK1 Surface altitude L-22 km site 15 TABLE15.WK1 Extensive surface altitude surveys (1973 & 1976) 17 TABLE17.WK1 Ice thickness 18 TABLE18.WK1 Local coordinates of geodetic control monuments 21 TABLE21.WK1 Centerline coordinate system
