In the original publication of this article (Kameo et al.
2020), a reference article is missing in the reference list.
The missing reference should be referenced at the location in the main body of the article below where “HoleU1427” is referred to.
Main Text:
Their occurrences suggest that the influence ofcoastal water near the coast of the Japanese islands
may have increased along with the Kuroshio Current
after the full interglacial during MIS 19. In Japan
Sea, subtropical Tsushima Warm Current radiolarianspecies were rapidly decreased in Hole U1427(Sagawa et al. 2018). Sagawa et al. (2018) suggested
that shallowing the Tsushima strait due to lowering
sea-level prevented the Tsushima Warm Current
from flowing into Japan Sea after interglacial
maxima.
