| Summary: | bon age determinations yielded results between 4190 + 60 years (Ua-4118) and 2885 I 60 years (Ua-2832), showing that this seldom mentioned pelecypod may have lived in northemmost Baffin Bay for some 1300 14C-years or 1600 cali-brated years. Furthermore, because this same species was collected alive close to the site of Core 008 in 1971, it may have persisted at this high latitude for much of the past 4000 years, or it may have disappeared, to re-establish itself in the area much more recently. As this pelecypod is quite abundant in deep water with positive temperatures off southern Greenland, it is classified as subarctic. Thus its presence in a deep trench well to the northwest of the marine subarctic bound-ary provides convincing evidence that wedges of warm Atlantic water have pen-etrated north of latitude 77 " for significant portions of the last 4000 years. |
