The reason viewers see their muscles emerging as the show goes on is because as the layer of fat surrounding the muscles is lost, muscles become more visible.

These low intensities are the lowest ever found for the Holocene and have not been reported outside of China.

We also report a spike intensity of 165.8 ± 6.0 ZAm Archaeomagnetism is an effective way to understand the variation of the geomagnetic field over periods of centuries to millennia during the Holocene.

In an effort to increase the number of proficient archaeomagnetic-sample collectors, different labs periodically offer training and certification sessions.

In these workshops, individuals become familiar with the theory behind archaeomagnetic dating and learn how to collect archaeomagnetic samples in a number of different field situations.

Large fluctuations of the geomagnetic field over the past few thousands of years have been reported, for example, as archaeomagnetic jerks in Europe (1, 2) and eastern Asia (3, 4), as spikes in the Levant (5–7), Turkey (8), and North America (9), as large decreases in paleointensity (DIPs) [DIPs of Kent and Schneider (10)] at ∼3000 BCE and ∼2200 BCE as well as a possible local high around 1300 BCE in China both reported by Cai et al. Apparent progress has been made on understanding variations of the geomagnetic field during the Holocene in the past few years (13).

However, detailed pictures of the global field remain indistinct.

Rock magnetic experiments, including hysteresis loops, isothermal remanent magnetization (IRM) acquisition curves, first-order reversal curves (FORCs), variation of magnetization versus temperature (M–T), and scanning electron microscope (SEM) images as well as elemental spectrum analysis, were conducted on representative samples.The “IZZI” paleointensity protocol (14), as well as partial thermal remanent magnetization (p TRM) checks (15), total TRM anisotropy correction (16), and cooling rate correction (17), was adopted in this study.The detailed experimental procedures can be found in ) Site map of this study and the published data from China.You can download and print a copy of the example by clicking on the figure.Record comments for each specimen, such as the presence or absence of plaster, whether it wobbled during collection, etc.Common practice is to designate the site from digits in the site number, followed by the sequential sample number -first, second, third, etc.
