Description
Summary:ABSTRACX The floor of the Arctic Ocean in photographs. Over 2,000 usable bottom photographs have been taken in the western Arctic Ocean. The 87 stations cover the major gebmorphic provinces of this part of the Arctic Basin, including the Alpha Cordillera, Mendeleyev Ridge, and Canada Abyssal Plain as well as smaller features. The ridge and plain provinces differ markedly in their bottom characteristics. Scattered rocks, living animals and indications of bottom current are most prevalent on the ridges. Trails are most abundant on the abyssal plains. The differences are attributed to bottom current distributions and turbidity cur-rents. Bedrock outcrops were observed on the tops of two knolls on the Mendeleyev Ridge. RÉSUMh. Le fond de t'océan Arctique en photographies. Dans la partie occiden-tale de l'océan Arctique, on a pris plus de 2,000 clichés du fond sous-marin. Les 87 stations couvrent les principales provinces géomorphologiques de cette partie du bassin arctique et comprennent la cordillère Alpha, la dorsale de Mendéléev et la plaine abyssale canadienne, ainsi que des reliefs de moindre importance. Les dor-sales et la plaine abyssale diffèrent beaucoup dans leurs caractéristiques de fond. Sur les dorsales, des roches éparpillées, des animaux vivants et des indices de cou-rants de fond dominent. Dans la plaine abyssale, les pistes d'animaux marins sont abondantes. On attribue ces différences à la distribution des courants de fond et aux courants de turbidité. On a observé des affleurements du soubassement sur le sommet de deux monticules de la dorsale de Mendéléev.
