    Spectral radiation fluxes, albedo and transmittance from autonomous measurement from Radiation Station 2020R22, deployed during MOSAiC 2019/20 (2022)
    PANGAEA
    In:  Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven
    Details
    Publication Date: 2024-06-25
    Description: Solar radiation over and under sea ice was measured by radiation station 2020R22, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during MOSAiC (Leg 5) 2019/20. The resulting time series describes radiation measurements as a function of place and time between 21 August 2020 and 12 September 2020 in sample intervals of 10 minutes. The radiation measurements have been performed with spectral radiometers. All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). Two sensors, solar irradiance and upward reflected solar irradiance, were mounted on a on a platform about 1 m above the sea ice surface. The third sensor was mounted 0.5 m underneath the sea ice measuring the downward transmitted irradiance.

    Total Sky Imager observations during POLARSTERN cruise PS127, Bremerhaven - Cape Town (2022)
    PANGAEA
    Details
    Publication Date: 2024-06-25
    Description: The dataset consist of camera shots of the sky. The camera - a total sky imager manufactured by Vivotek - was mounted at the top of the Research Vessel Polarstern. On the Atlantic transit from Bremerhaven to Cape Town in December 2021 this camera shots were taken with a temporal resolution of 15 seconds. The dataset represents the visible projection of weather conditions and cloud cover recorded on the vessel Polarstern in the direction near the zenith. These observations are useful for the interpretation of the atmospheric radiation measurements.

    Data collection of age determination data for LANDO multi-core study (2022)
    PANGAEA
    Details
    Publication Date: 2024-06-25
    Description: This data collection of age determination data from high latitude lake systems (50° N to 90° N, 55 sediment cores, and a total of 602 dating points) was part of the multi-core study of the LANDO approach. The term “LANDO” refers to the implementation by Pfalz et al. (2022), which stands for “Linked age and depth modeling”. We collected the data between 2018 and 2021 from either the Pangaea database, PaleoLake database, or tables within the main body or supplementary material of publications. The uploaded data collection contains links to the main data source and paper reference for the corresponding age determination dataset. The data harmonization followed the syntax and semantics proposed by Pfalz et al. (2021) on harmonizing heterogeneous multi-proxy data. This data collection is based on drilling campaigns from 1993 to 2020.

    Single-beam sea-ice draft from remotely operated vehicle (ROV) surveys during the MOSAiC expedition 2019/20 (2022)
    PANGAEA
    Details
    Publication Date: 2024-06-25
    Description: The distance between a remotely operated vehicle (ROV) and the sea-ice underside was measured by a single-beam upward-looking acoustic sonar altimeter (Tritech PA500) attached to the ROV during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition between November 2019 and September 2020. Sea-ice draft was derived by subtracting the distance to the sea-ice underside from the ROV depth, uncorrected for ROV attitude (pitch, roll). An offset between the depth reference (ROV bumper bars) and the altimeter of 0.105 m is accounted for in the presented data.

    Publication Date: 2024-06-25
    Description: This dataset contains the collection of available published paired Uk'37 and Tex86 records spanning multi-millennial to multi-million year time scales, as well as a collection of Mg/Ca-derived temperatures measured in parallel on surface and subsurface dwelling foraminifera, both used in the analyses of Ho and Laepple, Nature Geoscience 2016. As the signal-to-noise ratios of proxy-derived Holocene temperatures are relatively low, we selected records that contain at least the last deglaciation (oldest sample 〉18kyr BP).

    Temperature and heating induced temperature difference measurements from SIMBA-type sea ice mass balance buoy 2019T58, deployed during MOSAiC 2019/20 (2022)
    PANGAEA
    Details
    Publication Date: 2024-06-25
    Description: Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA 2019T58 (a.k.a. FMI_05_09, IRIDIUM number 300234065171790) is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the 1st leg of the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) in October 2019. The buoy was deployed at M4 site with initial thicknesses of snow and ice of 0.08 and 0.84 m, respectively, on 7 October 2019. The thermistor chain was 5 m long and included 241 sensors with a regular spacing of 2 cm. The depths for the sensors are 64 to -414 cm, referring to the initial interface between snow and ice. The last sensor was used to measure the air temperature at 1 m above the initial snow surface. The resulting time series describes the evolution of temperature and temperature differences after two heating cycles of 30 and 120 s as a function of depth and time between 7 October 2019 and 21 July 2020 in sample intervals of 6 hours for temperature and 24 hours for temperature differences. In addition to temperature, geographic position, barometric pressure, tilt and compass were measured.

    Processed data of CTD buoys 2019O1 to 2019O8 as part of the MOSAiC Distributed Network (2022)
    PANGAEA
    Details
    Publication Date: 2024-06-25
    Description: A set of eight ice-tethered buoy systems (2019O1 to 2019O8) were deployed by the Akademik Fedorov in the Northern Laptev Sea in early October 2019 as part of the MOSAiC Distributed Network. Each buoy consisted of 5 Seabird SBE37IMP Microcat CTDs mounted along an inductive modem tether at depths of 10, 20, 50, 75 and 100m. The CTDs were recording oceanographic data internally at 2-minute intervals. The surface unit of the buoy prompted the instruments for an additional measurement every 10 minutes, which was then transmitted to a base station via iridium along with GPS position and time, as well as surface temperature. After a several months long drift through the Central Arctic Ocean, 4 out of 8 buoys were recovered in August 2020, and the internally recorded data from the CTDs were secured. The 10-minute buoy data and 2-minute CTD data were co-processed and merged into a combined product. A buoy flag indicates whether a measurement was taken by the buoy (1) or was recorded by the CTD itself (0). The data were quality controlled by means of outlier detection using global limits, moving average filters and manual inspection. The dataset was carefully checked for inconsistencies, especially in the salinity. A (slightly modified) quality flagging scheme was applied according to the Ocean Data Standards Volume 3 (UNESCO 2013), where 1 = Good, 2 = Good (Modified), 3 = Questionable, 4 = Bad, 9 = no data. Finally, the data were validated against independent measurements. Details are available in the data paper indicted below.
