Atlantic Water modified by sea-ice melt and meteoric water at Barents Sea slope.
LHW may be divided into different types by Principal Component Analysis (PCA).
High salinity LHW-type forms in the Barents and Kara seas.
Low salinity LHW-types form in the western Laptev Sea or enter via Vilkitsky Strait.
PCA does not support a distinction between onshore and offshore LHW branches.
