This entire dataset should be cited as:

the MISOMIP2 MIPkit-W dataset (https://zenodo.org/doi/10.5281/zenodo.8316180) that includes data collected through multiple cruises of the Polarstern Research Vessel and originally provided by the Alfred Wegener Institute, Bremerhaven, Germany.
For more specific use of some of the MIPkit-W data, we encourage people to cite the original data referenced below.

Oce3d_MIPkitW_* : 3-dimensional temperature and salinity (horizontal slices every 100m)
The hydrographic properties provided on horizontal sections at 15 depths come from the CTD measurements obtained from late December to early March during the Alfred Wegener Institute Polarstern cruises ANT-XII/3 (Schroeder, 2010), PS82 (Schroeder, 2014), PS96 (Schroeder, 2016) and PS111 (Janout, 2019), which cover years 1995, 2014, 2016 and 2018, respectively.

OceSec<n>_MIPkitW_* : vertical sections
The first vertical section (OceSec1) goes from the tip of the Antartic Peninsula to Kapp Norvegia (12.33°E). It is known as WOCE-SR04 and has been monitored since 1989. The data provided were collected during Polarstern cruises in Sep.-Oct. 1989, Nov.-Dec. 1990, Dec. 1992-Jan. 1993, Mar.-May 1996, Apr.-May 1998 (Fahrbach and Rohardt, 1990, 1991, 1993, 1996, 1998), Jan.-Apr. 2005 (Rohardt 2010), Feb.-Apr. 2008 (Fahrbach and Rohardt, 2008), Dec. 2010-Jan. 2011 (Rohardt et al. 2011), Dec. 2012-Jan. 2013 (Rohardt 2013), as well as Dec. 2016-Jan. 2017 and Dec. 2018-Feb. 2019 (Rohardt and Boebel, 2017, 2020).
The second vertical section (OceSec2) is at approximately 76°S and covers the eastern side of Filchner Through. It was surveyed during some of the Polarstern cruises on 5-8 Jan. 2014 (Schroeder, 2014), 20-24 Jan. 2016 (Schroeder, 2016) and 4-23 Feb. 2018 (Janout, 2019).
The third and fourth sections were obtained along the front of Ronne (OceSec3) and Filchner (OceSec4) ice shelves, respectively. The Filchner section was measured on 1-3 Feb. 1977 by the Norwegian Antarctic Research Expedition with Research Vessel Polarsirkel (Foldvik et al., 1985), 7-16 Jan. 1981 (Hubold and Drescher, 1982), 25 Jan.- 4 Mar. 1995 (Schroeder, 2010), 15-17 Jan. 2014 (Schroeder, 2014), 15 Jan. 2016 (only one vertical profile; Schroeder, 2016), and 14-23 Feb. 2018 (Janout, 2019). The Ronne section was measured by some of these expeditions on 25 Jan.- 24 Feb. 1995, 14-15 Jan. 2016, and 9-14 Feb. 2018.
The files OceSec<n>_MIPkitW_model_lon_lat.csv contain the coordinates (longitude, latitude) at which model data should be interpolated to be compared to the observational sections.

OceMoor<n>_MIPkitW_* : moorings
Temperature, salinity and velocity time series are provided at three moorings placed along the 76°S vertical section and referred to as OceMoor1 (AWI252, 30.47°W), OceMoor2 (AWI253, 30.99°W) and OceMoor3 (AWI254, 31.48°W), and cover the period from Jan. 2014 to Feb. 2018 (Schroeder et al., 2017a,b,c, 2019a,b,c). Temperature, salinity and velocity data were obtained at two depths for AWI252 (335 and 421 m depth for a seafloor at 447 m) and AWI253 (349 and 434 m depth for a seafloor at 456 m), while a single depth is provided for AWI254 (553 m for a seafloor at 581 m).
