Late quaternary periplatform sediments and paleoenvironmental analysis of Pedro Channel, northeastern Nicaragua rise, Caribbean Sea
Using four periplatform sediment cores of intermediate water depth (900 to 1400 m) from the western Caribbean Sea, an investigation was conducted to ascertain the difference in cyclicity between the late-Brunhes Mode and the mid-Brunhes Mode. The past 185 ky define the late-Brunhes Mode, which recor...
