CTD data collected from MOCNESS hauls on R/V Oceanus and R/V New Horizon in the western North Atlantic from 2011-2012 (OAPS project)

<p>A standard 1-m2 Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS; Wiebe et al., 1985) was used to collect zooplankton to determine the taxonomic composition of the zooplankton in the study site with a specific focus on the shell bearing thecosomatous pteropods.&nbsp; It was also used to ground truth acoustic data collected with the HTI multi-frequency system and the Edgetech broadband system.</p>

<p>These data are the CTD data collected during the 1 meter2 MOCNESS tows. They provide standard environmental measurements simultaneously with the collection of the animals.</p>

<p>Fluorescence, oxygen and irradiance data were not collected from this instrument system.</p>
