Seasonal Changes in Iceberg Distribution off East Antarctica

Seasonal changes of human circadian rhythms in Antarctica.

The human circadian rhythms in sleep, activity, plasma melatonin, and rectal temperature were explored under two conflicting time cues in Antarctica: an extreme photoperiod and a strict work schedule. The nine healthy male subjects stayed at the Antarctic zone (latitude 66.5-90° south) for 15 mo including a 13-mo wintering at the Dome station (latitude 77° south). Neither the phases nor the amo...

Holocene Climate Changes Recorded in an East Antarctica Ice Core

Ice core derived proxy climate records from Antarctica suggest that decadal , century and possibly even millennial-scale temperature variations in East and West Antarctica may be temporally asynchronous. For example, records from the Antarctic Peninsula indicate a strong 20th century warming in which the high plateau of East Antarctica has not participated. Similarly, a recent Neoglacial coolin...

Study of seasonal distribution of dust in the Middle East region using CALIOP and MODIS data

Aerosol optical depth in 550 nm and angstrom exponent measurements with MODIS have been studied with 1-degree resolution for the period 2006-2017 in the middle east. Moreover, tropospheric aerosol optical depth and depolarization ratios measured at 532 nm with CALIOP have been studied for same area and same period of time too. These parameters have been classified seasonally. Optical depth resu...

Evidence for iceberg armadas from East Antarctica in the Southern Ocean during the late Miocene and early Pliocene

Seasonal distribution of myocardial infarction and seasonal mood changes.

REPLY We thank Kok, Umans, and Arnold for their statistical calculations. Indeed, a large sample size would be required to prove that there is equivalence in clinical outcome between patients directly admitted compared to transferred patients. To demonstrate that the six-month mortality rate would not exceed more than 1% (6% vs. 7%) would require a sample size of even more than 25,000 patients!...
