This is the common definition for Burst sampling, but other definitions maybe discussed within the wiki.
Each burst must be sufficiently long to derive turbulence statistics, which depends on the environment and sampling rate. For tidal systems, bursts are usually of the order of 5 to 10 min. Longer bursts may allow for more robust statistics or for segmenting datasets. For example, a burst lasting 18 min may be segmented into three 50% overlapping 9 min segments.
