متن کاملSpatial and Temporal Characteristics of the Little Ice Age: The Antarctic Ice Core Record
Recently, ice core records from both hemispheres, in conjunction with other proxy records (e.g., tree rings, speleothems and corals), have shown that the Little Ice Age (LIA) was spatially extensive, extending to the Antarctic. This paper examines the temporal and spatial characteristics of the dust and 5180 infonnation from Antarctic ice cores. Substantial differences exist in the records. For...
متن کاملDid earthquakes keep the early crust habitable?
The shallow habitable region of cratonal crust deforms with a strain rate on the order of approximately 10(19) s(1). This is rapid enough that small seismic events are expected on one-kilometer spatial scales and one-million-year timescales. Rock faulting has the potential to release batches of biological substrate, such as dissolved H(2), permitting transient blooms. In addition, the steady-st...
متن کاملLittle Ice Age (neoglacial) Paleoenvironmental Conditions at Siple Station, Antarctica
The 550-year records of 6180 and dust concentrations from Siple Station, Antarctica suggest warmer and less dusty atmospheric conditions from 1600 to 1830 A.D. which encompasses much of the northern hemisphere Little Ice Age (LIA).· Dust and 6180 data from South Pole Station indicate that the opposite conditions (e.g. cooler and more dusty) were prevalent there during the LIA. Meteorological da...
متن کاملThe Medieval Climate Anomaly and the Little Ice Age in the eastern Ecuadorian Andes
To better characterize the climate variability of the last millennium in the high Andes, we analyzed the pollen content of a 1150-yr-old sediment core collected in a bog located at 3800 m a.s.l. in the páramo in the eastern Cordillera in Ecuador. An upslope convective index based on the ratio between cloud transported pollen from the Andean forest to the bog (T) and Poaceae pollen frequencies, ...
