Editorial 
With this issue, Polar Research has gone over to 
a double-column layout more in line with today’s 
international publication standards. Basic edi- 
torial policy remains unchanged. 

The expansion of the scientific information sys- 
tem has resulted in the introduction of new tech- 
niques of information transmission. Readers need 
to obtain and identify published material as 
quickly as possible. Therefore, all abstracts in 
Polar Research include full bibliographic identi- 
fication. A page biblid will be added at a later 
stage to facilitate identification of photocopied 
single pages from an article. Such page identifi- 
cation has proved to be of more value to the users 

of a journal than the conventional running head. 
The present issue of Polar Research begins Vol. 

1, No. 1 of a New Series. This is in accordance 
with the general lines of international reference 
and abstracting services and ensures that research 
published in previous and future issues is readily 
obtainable. As well as containing complete source 
and citation details, title pages have the Norsk 
Polarinstitutt logotype providing instant identi- 
fication of coverless offprints.
