Late Holocene fluctuations of Quelccaya Ice Cap, Peru, registered by nearby lake sediments
(Wiley, 2015)
Records of clastic sediment from lakes that receive glacial meltwater provide a means for inferring past glacial fluctuations. However, increased clastic sedimentation has been interpreted to indicate both glacial advance ...
In and out of glacial extremes by way of dust climate feedbacks
(National Academy of Sciences, 2018)
Mineral dust aerosols cool Earth directly by scattering incoming solar radiation and indirectly by affecting clouds and biogeochemical cycles. Recent Earth history has featured quasi-100,000-y, glacial-interglacial climate ...
Fish debris in sediments from the last 25 kyr in the Humboldt Current reveal the role of productivity and oxygen on small pelagic fishes
(Elsevier, 2019)
Upwelling of cold, nutrient-rich water from the oxygen minimum zone (OMZ) off Peru sustains the world's highest production of forage fish, mostly composed of anchovy (Engraulis ringens). However, the potential impacts of ...
LATE PLEISTOCENE ICE FLUCTUATIONS AND GLACIAL GEOMORPHOLOGY OF THE ARCHIPIELAGO DE CHILOE, SOUTHERN CHILE
(TAYLOR & FRANCIS LTD, 2012)
Most of the last glacial maximum (LGM) glacier record west of the southern Andes (40-55 degrees S) is today submerged under the Pacific Ocean and therefore the Archipielago de Chiloe (42-43 degrees S) provides an unusual ...
