Part of this research was made possible by a grant from the Gulf of Mexico Research Initiative to support the Ecosystem Impacts of Oil and Gas Inputs to the Gulf (ECOGIG-2) research consortium. Funding for acquisition of the 2015 Arctic data was provided by NSF (1203473 and 1249133) and NOAA (NA15OAR4310155) under the NABOS-II program. Development of the prototype external magnetometer/accelerometer package (IMP) and methodology was carried out without external funding; extensive testing was carried out during cruises of the NSF-funded DIMES project (OCE-1232962). Participation of Ilona Goszczko on the NABOS cruise was made possible by the Polish National Science Center MIXAR project (2012/05/N/ST10/03643) and by funding from the Leading National Research Centre (KNOW) to the Centre for Polar Studies for the period 2014–18. Overall responsibility for CTD data acquisition and processing by Joe Montoya and Igor Polyakov for the Gulf of Mexico and Arctic CTD data, respectively, is gratefully acknowledged, as is the support by Piotr Wieczorek (IOPAN) for adapting an old ADCP pressure case and power supply for use with the IMP. The ECOGIG EN586 LADCP data are publicly available through the Gulf of Mexico Research Initiative Information and Data Cooperative (GRIIDC; https://data.gulfresearchinitiative.org; doi:10.7266/N7K072BN). The 2015 NABOS LADCP data are available on request from the authors.

This assertion was tested with an Xsens IMU that distinguishes between instrument tilt and horizontal acceleration, and that was deployed on a CTD rosette during two casts in rough seas in the Southern Ocean during the 2010 DIMES second U.K. (UK2) cruise (rms horizontal acceleration
