Two RDI Workhorse (300 kHz) Acoustic Doppler Current Profilers (ADCPs) were mounted on the CTD rosette (one upward- and one downward-looking). Data were processed with the LDEO IX13 LADCP package written in MATLAB and available from [Lamont-Doherty Earth Observatory](https://www.ldeo.columbia.edu/cgi-bin/ladcp-cgi-bin/hgwebdir.cgi), Columbia University, Earth Institute, US (Visbeck, 2002. Deep velocity profiling using lowered acoustic doppler current profilers: Bottom track and inverse solutions. J. Atmos. Oceanic Technol., 19, 794⁠ – ⁠807). The Ryder expedition was carried out with Swedish icebreaker Oden starting/ending in US Air Force Base Thule, Northwest Greenland, Aug 5/Sept 10, 2019. It was multidisciplinary with a broad range of data collected. The main target was Sherard Osborn Fjord where Ryder Glaciers drains the north-western Greenland Ice Sheet. Included in the expedition survey areas were also Petermann Fjord and adjacent Hall Basin, northern Nares Strait and an area northeast of Ellesmere Island in the Lincoln Sea.
