Fig. 2

A representation of two types of dive data streams collected concurrently on a single tag deployed on a Ziphius cavirostris. In gray is a pseudo-dive profile based on a dive summary record data stream which provides a maximum depth, start time, and end time for each dive. Note this is not a true dive profile as only maximum depth and general shape of the dive are indicated (see Methods for details). In black are time-series depths with reported error bands indicated by blue segments. Top panel shows the native resolution of time-series data for this deployment (period = 2.5 min), while the middle and bottom panel show resampled time-series data (period = 5.0, 7.5)
