    Description: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉Abstract〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉The collection of zooplankton swimmers and sinkers in time‐series sediment traps provides unique insight into year‐round and interannual trends in zooplankton population dynamics. These samples are particularly valuable in remote and difficult to access areas such as the Arctic Ocean, where samples from the ice‐covered season are rare. In the present study, we investigated zooplankton composition based on swimmers and sinkers collected by sediment traps at water depths of 180–280, 800–1320, and 2320–2550 m, over a period of 16 yr (2000–2016) at the Long‐Term Ecological Research observatory HAUSGARTEN located in the eastern Fram Strait (79°N, 4°E). The time‐series data showed seasonal and interannual trends within the dominant zooplankton groups including copepoda, foraminifera, ostracoda, amphipoda, pteropoda, and chaetognatha. Amphipoda and copepoda dominated the abundance of swimmers while pteropoda and foraminifera were the most important sinkers. Although the seasonal occurrence of these groups was relatively consistent between years, there were notable interannual variations in abundance, suggesting the influence of various environmental conditions such as sea‐ice dynamic and lateral advection of water masses, for example, meltwater and Atlantic water. Statistical analyses revealed a correlation between the Arctic dipole climatic index and sea‐ice dynamics (i.e., ice coverage and concentration), as well as the importance of the distance from the ice edge on swimmer composition patterns and carbon export.〈/p〉

The time-series data include the abundance of copepoda, foraminifera, ostracoda, amphipoda, pteropoda, and chaetognatha that were collected in the sediment trap time-series.

The mooring was deployed during RV POLARSTERN expedition PS126 and recovered during PS131. The attached archive contains raw data files of four Seabird SBE37 MicroCATs (nominal depths: 17m, 22m, 46m, 241m; sampling interval 1h), one SBE56 temperature logger (nominal depth: 36m, sampling interval 60s), one Wetlabs ECO PAR sensor (nominal depth: 22m; sampling interval 1h), one Wetlabs ECO Triplet fluorometer (nominal depth: 22m; sampling interval 2h), two Satlantics SUNA nitrate sensors (nominal depths: 22m, 241m; sampling interval 4h), two Sunburst SAMI-pCO2 sensors (nominal depths: 22m, 241m; sampling interval 1h) and two Sunburst SAMI-pH sensors (nominal depths: 22m, 241m; sampling interval 3h). The mooring also included two McLane RAS water samplers (nominal depths: 22m, 241m; data archived elsewhere), two sediment traps (nominal depths: 194m, 603m; data archived elsewhere), and four PE samplers (nominal depths: 64m, 248m, 503m, 1112m; data archived elsewhere). Auxiliary information such as sensor calibration sheets, mooring diagrams, and schedule files are also provided, if applicable. The pH sensor at 22 m and both SUNAs had issues and did not record any data.
