Diatom abundance in sediments of ODP Holes 186-1150A and 186-1151C
Listed in PANGAEA
The diatom flora from two sediment cores recovered from the upper 27 meters below seafloor (mbsf) in the oceanic frontal area off Sanriku, northeast Japan, during Ocean Drilling Program Leg 186 were analyzed.
Description
Diatom abundance seems to be in interglacial stages and suggests a south-north shifting of the frontal area. Diatom temperature values are less reliable because frequency of the warm-water species is smaller.
Site 1151 was in a warm climate at ~50 ka, as were Deep Sea Drilling

Project
Sites 579 and 580 in the western North Pacific Ocean. A mixed diatom assemblage in the upper 3 mbsf at Site 1150 is evidence that the Tsugaru Warm Current flowed into the studied area through the Tsugaru Strait.
