sounders were taken by all four icebreakers and the WYANDOT, ARNEB, 

 CURTIS, and NESPELEN, In some cases, such as aboard the STATEN ISLAND, 

 the echo sounder was raalfimctional beyond the repair capacity of the 

 ship's force, and the data retvirned were limited in amount and quality. 



All soundings obtained are processed and retained in the U. S. 

 Navy Hydrograpnic Office, and are being incorporated in revised 

 editions of pertinent charts, or in new charts published by this Office, 

 Reports on dangers and aids to navigation, displacements of major 

 coastal features, chart correction information, and position and 

 contours of the shelf ice edge are also processed and retained within 

 this Office, for incorporating into existing or new publications. 



A limited small boat survey of the water areas surrounding Wilkes 

 Station in the Windmill Islands off the Budd Coast was undertaken. On 

 the return voyage back to the United States, the GLACIER undertook a 

 brief and unsuccessful search for Maria Theresa Reef, originally 

 reported in November, 1843, at about 151°13'W between 35° and 37°S,
