The characterization of Last Glacial millennial-timescale warming phases, known as interstadials or Dansgaard-Oeschger events, requires precise chronologies for the study of paleoclimate records. On the European continent, such chronologies are only available for several Last Glacial pollen and rare speleothem archives principally located in the Mediterranean domain. Farther north, in continent...
Late Neogene paleoceanographic history in the western North Pacific is discussed on the basis of: (1) Td (diatom temperature) values, (2) species composition, and (3) the structure of diatom assemblages at Sites 579 and 580. These factors provide a record of fluctuations of the past position of the subarctic-subtropic front because these sites lie within the transition zone between the modern d...
Benthic response to chronic natural physical disturbance by glacial sedimentation in an Arctic fjord
10 Recent sedimentation along the Hikurangi subduction margin off northeastern New Zealand is 11 investigated using a series of piston cores collected between 2003 and 2008. The active Hikurangi 12 Margin lies along the Pacific-Australia subduction plate boundary and contains a diverse range of 13 geomorphologic settings. Slope basin stratigraphy is thick and complex, resulting from sustained h...
