trending generally north to south 2.6 miles due east of Ras 

 al Ardh. The water to the west of the brown foam line that 

 perhaps marked the boundary between waters of different 

 densities was blue-green in color and less muddy than 

 that water to the east of the line. 



"On March 19, 1949 a very excellent line of color 

 demarcation was noticed at the ten-fathom line 41 miles 

 east of Fantas (located at 29°10.0'N., 48°07.5'E.). The 

 color of the water changed from a rather muddy blue-green 

 to a much clearer blue-green. However, without a color 

 scale it is hard to describe the color change much more 

 accurately. The depth beyond this point began increasing 

 from a constant fathometer reading of 53 feet to 60 feet at 

 a rate of one foot per minute - ship moving at about seven 

 knots. These facts would indicate - as the charts show - 

 that this color line and slight depth increase mark the limit 

 of the main underwater mud delta laid down by the rivers 

 flowing into the north end of the gulf. 



"Five Secchi disk measurements were made throughout 

 the gulf. The disk was visible for a depth of only 4.5 feet 

 off the beach at Faylakah Island, for 10.5 feet at the 

 western end of Kuwait Harbor (shown in Fig. 11), for 20 

 feet at Sitra Anchorage (Bahrein Island), for 60 feet in 

 the vicinity of Shah Allum Shoal, and for 15 feet in the 

 shade and 20 feet in the sun in the Strait of Hormoz. All 

 the observations except that at Sitra Anchorage were made 

 around 1300 LST with the one at Sitra taken at 1600 LST. 

 The skies were partly cloudy, and the winds averaged 

 Beaufort force 2. The colors of the water ranged from 

 a grey, muddy green in the north, through a clear blue- green 

 in the central parts of the gulf, to a dark murky green in 

 the strait." 



Biology 



No biological observations were made in the Kuwait area, and the 

 notes quoted below refer to the southern half of the gulf. 



"It was reported to Mr. T. J. Wehe by members of the 

 United Geophysical Company's seismic party that between 

 Christmas and New Year's Day on the shoals 15 miles 

 south of and 10 miles east of Bahrein Island hundreds 

 of dead fingerlings and a few dead large fish were noted.
