Postglacial change in sea level in the Western north atlantic ocean.

摘要: Radioactive carbon determinations of the age peat indicate that at Bermuda, southern Florida, North Carolina, and Louisiana relative sea level has risen approximately same rate, 2.5 x 10 -3 foot per year (0.76 meter year), during past 4000 years. It is proposed tentatively this rate eustatic change in level. The rise along northeastern coast United States been a much greater than this, indicating local subsidence land. Between Cape Cod northern Virginia, coastal 13 feet appears to have occurred between 2000 years ago continued about 1 since then. On Massachusetts, 6 3000 ago; then rate. 12,000 ago, rose an average 11 year. part played by or temporary departures from period uncertain.
