The meeting's chairman kept referring to the Holocene, the "wholly recent" epoch, which began at the conclusion of the last ice age, eleven and a half thousand years ago.
Most of Southern California, including all of Orange County, was periodically part of the Pacific Ocean; the most recent epoch was approximately 10 million years ago (MYA).
We inferred the parameters only for the most recent epoch, which is of generalized growth in one model while limited to exponential growth in the other.
The Quaternary Period (i.e., about the past 2,600,000 years) is divided into the Pleistocene Epoch (about 2,600,000 to 11,700 years ago) and the Holocene, or Recent, Epoch (the past 11,700 years).
The newest and most entirely recent epoch, postmodern as that sounds, should be the Anthropocene, the group argues.
In a more recent epoch, the writers of Victorian England, fogged over with puritan fears and piqued perhaps by bursts of scientific revelations, contemplated civilization's fall to plague, beast and Martian.
From each set of simulations, we then inferred four parameters of the recent growth epoch, which can uniquely determine the epoch: (1) the growth speed parameter b; (2) the initial population size before growth, N f ; (3) the ending population size after growth, N i ; and (4) the onset time of growth T, which is equivalent to the growth duration since the simulated epoch ends at present.
Towards the most recent epochs, it is primarily constrained by first differences of observatory annual means and measurements from the Oersted, Champ, and Swarm satellite missions.
On average, the UMSL from the low to mid-latitude sites is similar for all three geomagnetic components (a couple of nT towards the most recent epochs), even though perturbations may be larger at some periods and locations for Z. Depending on the observatory, it ranges between 1 and 10 (6) nT for Z (X and Y) data.
