Extended Data Fig. 1: Global CALIOP observational coverage.
From: Global satellite-observed daily vertical migrations of ocean animals
a–e, CALIOP ground tracks for 1 (a), 2 (b), 4 (c), 8 (d) and 16 (e) days. f, Number of months for each 2° × 2° bin with day and night retrievals of bbp for the 2008–2017 study period. The total number of months possible is 115. The north–south strip of low retrieval success in the middle of the Pacific is caused by a gap in ancillary AMSER surface wind data. AMSER wind data are used for flagging CALIOP data with potential bubble contamination (Methods).
