Downward flux of chlorophyll a, phaeophytin, particulate organic carbon (POC), particulate organic nitrogen (PON), and the atomic ratio of POC:PON at 3 stations on the West Greenlandic continental shelf (67.5-70.5 N, 56.2-56.9 W) in July 2021, project ECOTIP

As part of the project ECOTIP, a field campaign was conducted along the West Greenlandic continental shelf in July 2021 with the R/V Dana. A short-term sediment trap array (KC Denmark type) was deployed for 18.7-24.4 hours at 3 stations: 1) Dana2021_station14 on 21 July 2022,
2) Dana_station22 on 26 July 2022, and 3) Dana_station28 on 24 July 2022. The downward flux of the following parameters was assessed in sediment trap cylinders (inner diameter 72 mm, KC Denmark, aspect ratio 6.25), which were deployed empty and filled themselves during deployment. The cylinders were placed at 5 sampling depths: 20, 30, 50, 90, 120 m. The following parameters were determined: 1) the downward flux of total (> 0.7 micrometre) chlorophyll a (Chl a) (mg Chl a m^-2 d^-1), 2) the downward flux of Chl a > 10 micrometre (mg Chl a > 10 micrometre m^-2 d^-1), 3) the downward flux of total (> 0.7 micrometre) phaeophytin (Phaeo) (mg Phaeo m^-2 d^-1), 4) the downward flux of Phaeo > 10 micrometre (mg Phaeo > 10 micrometre m^-2 d^-1), 5) the downward flux of particulate (>0.7 micrometre) organic carbon (POC) (mg POC m^-2 d^-1), 6) the downward flux of particulate (>0.7 micrometre) organic nitrogen (PON) (mg PON m^-2 d^-1), and
7) the atomic ratio of PON:PON of the sinking matter. The data are presented here in one file per sampling station. The file title and the ID refer to the sampling station and date of the sediment trap deployment (YYYYMMDD). References to additional data from the same field campaign and details of the sample analyses can be found in each netCDF and in the Read_me file.
