Bedrock cores from 89 degrees North: Implications for the geologic framework and Neogene paleoceanography of Lomonosov Ridge and a tie to the Barents shelf

• Two piston cores from the Eurasian Rank of Lomonosov Ridge near lat 88.9 degreesN, long 140 degreesE provide the first samples of bedrock from this high-standing trans-Arctic ridge. Core 94-PC27 sampled nonmarine siltstone similar in facies and age to upp
