ENSO and Solar Activity Signals From Oxygen Isotopes in Diatom Silica During Late Glacial-Holocene Transition in Central Andes (18°S)
(Springer, 2010-02)[Abstract] The late glacial-Holocene transition from the Lago Chungará sedimentary record in northern Chilean Altiplano (18°S) is made up of laminated sediments composed of light-white and dark-green pluriannual couplets ... -
Biogeochemical Processes Controlling Oxygen and Carbon Isotopes of Diatom Silica in Late Glacial to Holocene Lacustrine Rhythmites
(Elsevier, 2010-05-19)[Abstract] Biogeochemical cycles and sedimentary records in lakes are related to climate controls on hydrology and catchment processes. Changes in the isotopic composition of the diatom frustules (δ18Odiatom and δ13Cdiatom) ... -
Carbonate and Organic Matter Sedimentation and Isotopic Signatures in Lake Chungará, Chilean Altiplano, During the Last 12.3 kyr
(Elsevier, 2011-05-22)[Abstract] Sediments in lakes in the Andean volcanic setting are often made up of diatomaceous ooze together with volcaniclastics and small amounts of carbonates. Despite their scarcity, carbonates along with organic matter ... -
Formation and Evolution of Back-Barrier Perched Lakes in Rocky Coasts: An Example of a Holocene System in North-West Spain
(Wiley, 2018-09-22)[Abstract] Coastal back-barrier perched lakes are freshwater bodies that are elevated over sea-level and are not directly subjected to the inflow of seawater. This study provides a detailed reconstruction of the Doniños ... -
Climatic Fluctuations in the Hyperarid Core of the Atacama Desert During the Past 215 ka
(Springer Nature, 2019-03-27)[Abstract] Paleoclimate records from the Atacama Desert are rare and mostly discontinuous, mainly recording runoff from the Precordillera to the east, rather than local precipitation. Until now, paleoclimate records have ...
