Atmospheric dynamic response by obliquity forcing
(Universidad de Chile, 2019)
En esta tesis presento la evolución de las variables atmosféricas que determinan el clima planetario al variar el parámetro de oblicuidad.
Usando un modelo de circulación general de la atmósfera acoplado a un océano soméro ...

In the littoral zone of Argentina, marsh environments under arid, semi-arid and humid conditions are numerous. In this work, salt marshes located in Río de la Plata Estuary, Bahía Blanca Estuary, San Antonio Bay and San ...
Glacier and terrestrial ecosystem evolution in the Chilotan archipelago sector of northwestern Patagonia since the Last Glacial Termination
(2022)
We examine the glacier, terrestrial ecosystem, and climate evolution since the Last Glacial Termination (T1) based on glacial sediments/landform assemblages and palynological data from the Chilotan archipelago (41°30′S-43°30′S), ...
Timing and structure of the 8.2 kyr BP event inferred from delta(18)O records of stalagmites from China, Oman, and Brazil
(GEOLOGICAL SOC AMER, INC, 2009)
Oxygen isotope records of stalagmites from China and Oman reveal a weak summer monsoon event, with a double-plunging structure, that started 8.21 +/- 0.02 kyr B. P. An identical but antiphased pattern is also evident in ...
