A total of 38 box cores were collected from the Amerasian Basin, Arctic Ocean during the U.S. Geological Survey 1992 (PI92-AR) and 1993 (PI93-AR) Arctic Cruises aboard the U.S. Coast Guard Icebreaker Polar Star. In addition, the cruises collected geophysical data, piston cores and hydrographic data to address the geologic and oceanographic history of the western Arctic Ocean. This paper reports...

The fossil record is the only source of information on the long-term dynamics of species assemblages. Here we assess the degree of ecological stability of the epifaunal pterioid bivalve assemblage (EPBA), which is part of the Middle Devonian Hamilton fauna of New York--the type example of the pattern of coordinated stasis, in which long intervals of faunal persistence are terminated by turnover...

The East China Sea (ECS) seasonally receives a high organic input due to the terrestrial matter influx, which is controlled by Asian Summer Monsoon (EASM), and increased productivity driven upwelling of subsurface Kuroshio Current (KC). Changes in benthic foraminiferal assemblage composition combination with paleoceanographic proxy data (CaCO3 (%), TOC δ13Cpf, δ18Obf) are used reconstruct botto...
