However, the timing and duration of the excursions recorded in the loess sections are not well determined because remanence acquisition is possibly influenced by post-depositional processes (Roberts and Winklhofer 2004; Sun et al. 2013).
Mauchline and Gordon (1991) noted that much was yet unknown about the frequency and duration of the pelagic excursions and suggested for the Rockall Trough, based on the few pelagic observations, that "such excursions are rare or on a short-time scale [21].
For these investigators, excursions were limited to within 500 vertical metres of the EBC altitude for the duration of the expedition.
The duration of the expulsion is indefinite.
The global implications of the magnitude and short duration of the negative δ13Corg excursion reported here remain to be verified at other middle late Norian boundary intervals worldwide.
Despite hot discussions about the dating and duration of the BGE, this excursion is now accepted as a globally geomagnetic anomaly in the late Quaternary (Singer 2014).
An excursion was defined as all consecutive recordings outside the boundary covering at least 10 min. The duration of an excursion was defined as the elapsed time from first excursion to the first reading indicating return inside the excursion boundary.
Continuous glucose monitoring (CGM) provides a more complete view of glycemic excursions, including the duration and frequency of the excursions, and allows calculation of features of GV.
In paleomagnetic studies to identify and characterize such geomagnetic excursions from sediments, a well-established age model, high sedimentation rate (due to the limited duration of geomagnetic excursions), and identification of the magnetic mineralogy in particular are essential.
Cells were added at room temperature, not on ice or at 37°C, and it was desirable to limit the duration of this temperature excursion.
Each glucose excursion was characterized by baseline glucose level, peak glucose level, end glucose level, duration of excursion, time spent >180 mg/dl, area under the curve >180 mg/dl (AUC >180), total amplitude of excursion (Δ glucose), average rate of change, and insulin administered.
