Per station summaries of acoustic water column properties during MALASPINA-2010


This file provides daily/per station summaries of daytime and nighttime acoustic data (omitting data recorded within 1 hour of sunrise and sunset), specifically per day and night mesopelagic average nautical area scattering coefficient (NASC 200-1000 m), average total NASC (0-1000 m), and weighted mean depths (WMD) of mesopelagic and total NASC. Migration amplitude is the difference in day and night WMD, day to night ratio is the ratio of daytime to nighttime total NASC (0-1000 m) and migration ratio is calculated from the relative drop in mesopelagic backscatter (NASC 200-1000 m) during night. For details of calculations see Klevjer et al. 2016. Note that the provided positions correspond to the fixed Malapina station at that date, not the start and end point of the data collection.
