The biology of the Atlantic walrus Odobenus rosmarus rosmarus (Linnaeus) in the Eastern Canadian Arctic / authorship, A. W. Mansfield. : Fs52-2/653E-PDF
"Sections of molariform teeth reveal well defined incremental layers which are almost certainly annual in formation. Comparison of specimens from northern Hudson Bay and the Bering Sea shows that the Atlantic walrus is slightly smaller in body size and much shorter in tusk length than the Pacific walrus. The specimens from Foxe Basin are slightly larger in body size than those from Hudson Bay, which suggests that comparatively isolated breeding groups have been formed"--Abstract, page [i].
