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.Citation

Stable isotope data of mesozooplankton for depth layers along the Malaspina-2010 expedition(PANGAEA - Data Publisher for Earth & Environmental Science, 2020) [Dataset]Carbon export (from the epipelagic towards the mesopelagic zone) and sequestration (from the mesopelagic towards the bathypelagic zone) in the ocean are reviewed. Particulate organic carbon (POC) flux, and active flux due to migrant zooplankton and micronekton are shown from the epipelagic to the mesopelagic zone, and from the latter to the bathypelagic zone. Values towards the meso- and bathypelagic zones are compared in oligotrophic and productive systems. Zooplankton and prokaryote respiration in the meso- and bathypelagic zones of the ocean are also reviewed for oligotrophic and productive systems. Values were integrated over a depth layer and are given as the flux or respiration under one square meter (in g/m**2/a) between e.g. 100 m and 1000 m depth.
