PREFACE 



The oceanographic cruise covered by this report was planned 

 with the assistance of Dr. Thomas G-. Thompson of the oceanographic 

 laboratories of the University of Washington. Through his efforts two 

 very efficient observers, Dr. Phifer and IVIr, C. Barnes, also of the 

 University of Washington were detailed to the Gutter CHELAU for duty. 

 These men brought with them all the necessary ecLuipmcnt to outfit the 

 sick bay of the cutter into an actively functioning laboratory. Ac- 

 companying them was Professor J, L. Alexander of the Forestry Section 

 of the University of Washington, who assisted in the research and who 

 also investigated the tree life of those sections of Alaska visited and 

 who planted seeds and seedlings on many of the islands of that country. 



To Dr. Thompson, Dr, Phifer and Mr. Barnes belong the credit 

 for making the chemical analysis of water, marine life and marine growth. 

 Further credit is given for their assistance in making many of the calcu- 

 lations and summarizing much of the data without which groat difficulty 

 would have been encountered in compiling tMs report. 



The officers and crew of the CHEIAI\I deserve much credit for 

 their untiring efforts to make the cruise a success. Their interest and 

 wholehearted cooperation made the season of 1934 a productive and inter- 

 esting one, both from the view point of the Coast Guard Patrol duties and 

 also from the angle of scientific research. 



The stenographic force and the drafting room personnel of the 

 Communication Office, Coast Guard Headquarters, are thanked for their 

 able assistance in assembling the data. 



This report summarizes the physical investigation. The results 

 of the chemical investigation will not be ready until March 1937 at which 

 time they will be published as an addenda.
