    Nutrient and oxygen concentrations, alkalinity and pH measured on water bottle samples collected during cruise Transdrift-XXII (VB14) in 2014, Laptev Sea (2021)
    PANGAEA
    Details
    Publication Date: 2023-03-14
    Description: We collected seawater samples during TRANSDRIFT XXII Expedition in September and October 2014 along with CTD (conductivity, temperature, depth) profiles with a SBE 32 rosette water sampler equipped with 12 Niskin bottles (2.5 L) under ice-free conditions onboard the Russian research vessel RV Viktor Buynitskiy on the entire Laptev Sea shelf and above the shelf slope. The dataset includes nitrate, nitrite, ammonia, total nitrogen, phosphate, silicate and oxygen concentration data, as well as pH and total alkalinity, which provide important information on the geochemical state of the Laptev Sea.

    Description: A total of four moorings ("1893", "Taymyr", "Kotelny", "Vilkitsky") was deployed in September 2013 during the Transdrift 21 - expedition and recovered in September 2014 during Transdrift 22 aboard the Viktor Buinitsky. The expeditions were carried out in the framework of the German-Russian "Laptev Sea Systems" partnership, and within the BMBF-funded "Transdrift"-project. The moorings were equipped with RDI-Workhorse ADCPs for current measurements and Seabird SBE37 for temperature and salinity measurements. Sampling intervals were 1 hour for ADCP, and 30 minutes for SBE37. Currents were corrected for misalignment based on angles extracted from: https://geomag.nrcan.gc.ca/calc/mdcal-en.php Not all SBE37 models included a pressure sensor. If pressure was recorded, the data files provide pressure and the converted water depth. For models without a pressure sensor, the data file lists only a constant value indicating the targeted instrument depth. Temperature and salinity data were despiked, and outliers exceeding three times the standard deviation were removed and interpolated.

    Raw bottom track error velocity and range data from moored upward-looking Acoustic Doppler Current Profilers in the Laptev Sea between 2013 and 2015 (2019)
    PANGAEA
    Details
    Publication Date: 2023-03-16
    Description: Within the framework of the Russian-German BMBF-funded TRANSDRIFT project moored upward-looking Acoustic Doppler Current Profilers (ADCPs) were deployed in the Laptev Sea between 2013 and 2015. Two upward-looking Workhorse 300 kHz Sentinel ADCPs (manufactured by Teledyne RDI) were deployed at the 1893 and Taymyr stations in September 2013. During a Russian expedition in September 2014 both moorings were recovered and partly redeployed at the two stations until September 2015 (one upward-looking ADCP was substituted in 2014). The four data sets (ADCP_BT_1893_1314.txt, ADCP_BT_Taymyr_1314.txt, ADCP_BT_1893_1415.txt and ADCP_BT_Taymyr_1415.txt) are named to indicate the location of the deployment (station name) and the sampling period. Each file contains hourly values of error velocity (in mm/s) and range (beams 1 to 4, in m) data that was recorded using the ADCPs bottom track (BT) mode. Additionally, the instruments roll and pitch values (in deg) are included. The deployment sheets are attached as well. All moorings were equipped with numerous other instruments. Their data has been published separately.

    Underway CTD measurements during Akademik Tryoshnikov cruise AT2018 to the Arctic Ocean (2019)
    PANGAEA
    Details
    Publication Date: 2023-03-16
    Description: Underway (U)CTD data were collected during an August-September 2018 expedition to the Arctic Ocean aboard the RV Akademik Tryoshnikov, and was a joint expedition between the German-Russian project CATS (Changing Arctic Transpolar System) and the US-Russian project NABOS (Nansen and Amundsen Basin Observing System). The UCTD was operated mostly in yoyo-mode during selected transects between the shelf and the basin across the continental slope of the Eurasian Basin while the ship was transiting with 8 - 14 knots. The UCTD probe records the start time of the measurements and stores 16 samples each second internally. The exact location of each profile was subsequently found based on the time stamp from the cruise track. The unpumped conductivity sensor has a slower response time than the temperature sensor, which makes the computation of salinity from conductivity and temperature potentially spiky, especially in the pycnocline or in frontal regions. We followed the recommendation of the manufacturer to calculate salinity with Seabird processing software. In shallower waters (〈200m), the water column was profiled all the way to the seafloor, while in deeper waters, only the upper 200-350m were sampled. Shipboard echo soundings were not available, actual water depths at the profile locations need to be extracted from bathymetric charts (for instance IBCAO ). The UCTD was calibrated against a Seabird 911 CTD during the cruise. Temperature measurements were comparable to the ship's CTD and remained uncorrected, the processed salinities include a salinity correction based on a deviation from the ship's CTD.
