The frequency of TAI is higher at aphelion (about July 3) than at perihelion (about January 4) by about 6.6 parts in 1010, and TAI is more advanced in epoch by about 3.3 milliseconds on October 1 than on April 1.
Since the parent model was computed for the epoch 2014.3, we advanced the main field coefficients to 2015.0 using the linear secular variation.
During the Pleistocene Epoch (about 2,600,000 to 11,700 years ago), ice sheets advanced and retreated several times and deposited a thick layer of clay on the seafloor.
During the Pleistocene Epoch, ~2.6 0.01 million years ago, the North American Laurentide Ice Sheet advanced south to the Ohio River system, altering population distributions and genetic compositions [ 19, 20].
Poland's relief was formed by the actions of Ice Age glaciers, which advanced and receded over the northern part of the country several times during the Pleistocene Epoch (from about 2,600,000 to 11,700 years ago).
Subsequently, ice advanced across and retreated from the Sabrina Coast continental shelf at least 11 times during the Oligocene and Miocene epochs.
One epoch, equivalent to advancing time by one step, consists of examining each terminal in the system and deciding whether to move it.
Epoch Lacrosse began selling equipment in 2011 with the goal of advancing the technology being used in lacrosse equipment.
Most ornithologists believe that most modern species of birds arose during the early Pleistocene Epoch (about 2,600,000 to 11,700 years ago), a period of cooling temperatures, shifts in habitats, and advancing glaciers.
The aim of the paper is to advance knowledge in this field by developing a set of loading conditions for a typical Portuguese ship of this epoch, for both the voyage from Lisbon to India and the return voyage.
This period has sometimes been referred to as the "Neoglacial". In the middle latitudes this cooling trend was associated with intermittent periods of advancing and retreating mountain glaciers reminiscent of (though far more modest than) the more substantial advance and retreat of the major continental ice sheets of the Pleistocene climate epoch.
