description: Weddell seals (Leptonychotes weddellii) were immobilised during expedition PS124 (2021) for the purpose of deployments with satellite transmitters. The deployments (n=10) were located in the Filchner-Outflow-System (FOS), southern Weddell Sea. The seals were captured along the ships' tracks during ahead flights of the board helicopter and immobilised and instrumented on pack ice with Argos-linked (CLS, Toulouse, France) satellite-relayed dive loggers combined with CTD's (CTD-SRDLs, Sea Mammal Research Unit, UK) to investigate their ranging and foraging behaviour in the context of oceanographic features.

description: The total weight percent of sedimentary carbon (% C) and nitrogen (% N), as well as inorganic carbon (% Cinorg) and organic carbon (% Corg) were measured using a macro elemental analyzer LECO CNS2000 at CACTI (Universidade de Vigo, Spain). For the estimation of %Cinorg an aliquot of the homogenized and ground samples was heated at 450ºC for 3 hours to remove organic carbon. The % Corg content was calculated as the difference between % C and % Cinorg. The concentration opal was determined using the method of Mortlock and Froelich (1989). The Siopal/Corg(Si/C) were calculated after transformation of the biogenic silica (opal) and % Corg into molar ratios. The age model is calculated as indicated in doi:10.1594/PANGAEA.971417.

description: Here, we present a first (low-resolution) biomarker sea-ice proxy record from the High Arctic (southern Lomonosov Ridge), going back in time to about 60 ka (MIS 3 to MIS 1). Variable concentrations of the sea-ice diatom specific highly branched isoprenoid (HBI) with 25 carbon atoms ("IP25"), in combination with the phytoplankton biomarker brassicasterol, suggest variable seasonal sea-ice coverage and open-water productivity during MIS 3. During most of MIS 2, the spring to summer sea-ice margin significantly extended towards the south, resulting in a drastic decrease in phytoplankton productivity. During the Early Holocene Climate Optimum, brassicasterol reached its maximum, interpreted as signal for elevated phytoplankton productivity due to a significantly reduced sea-ice cover. During the mid-late Holocene, IP25 increased and brassicasterol decreased, indicating extended sea-ice cover and reduced phytoplankton productivity, respectively. The HBI diene/IP25 ratios probably reached maximum values during the Bølling-Allerød warm period and decreased during the Holocene, suggesting a correlation with sea-surface temperature.

title: Raw data of strain measurements on the ship structure of RV Polarstern during the MOSAiC expedition

description: The strain measurement system on bord of the R.V. Polarstern is an autonomous system to record the structural response caused by ice pressure on the ship's structure. For this purpose, 36 strain gauge full bridge circuits are installed on six frames and one deck 2 (F-Deck) in the void spaces 92 and 100 at starboard side between frame 78 and frame 81. The strain signals are measured time synchronously with a Gantner measuring amplifier with an internal sampling rate of 1000 Hz. To ensure a long run time with limited memory, only one data set per second and statistic variables (actual value, minimum and maximum value, mean value and standard deviation) over ten minutes measuring time each are stored on two redundant storage medias. Furthermore, the system is connected with the on-board power supply and the time synchronization server.

The sensors are installed on the outer shell, frames and on deck 1 (E-Deck) and deck 2 (F-Deck). To ensure a long run time with limited memory, only one data set is stored every five minutes by Driesen+Kern data loggers.

description: This data contains the total inorganic carbon content of the sediments of ODP Site 202-1242. Bulk sediment samples were dried at 45°C, ground and homogenized using a zircon ball mill. We calculated the weight percentage of sedimentary total inorganic carbon (% TIC) as the weight percentage of an aliquot of the sample measured after being heated at 400ºC for 3 hours to remove organic carbon. The weight percentage of carbon was measured using a macro elemental analyzer LECO CNS2000.

description: In the light of rapidly diminishing sea ice cover in the Arctic during the present atmospheric warming, it is imperative to study the distribution of sea ice in the past in relation to rapid climate change. Here we focus on glacial millennial scale climatic events (Dansgaard/Oeschger events) using the new sea ice proxy IP25 in combination with phytoplankton proxy data and quantification of diatom species in a record from the SE Norwegian Sea. We demonstrate that expansion and retreat of sea ice varied consistently in pace with the rapid climate changes 90 ka to present, and with this present the first IP25 sea ice proxy record resolving the D/O cyclicity going back in time into Marine Isotope Stage 5a. Sea ice retreated abruptly at the start of warm interstadials, but spread rapidly during the cooling phase of the interstadials and became near-perennial and perennial during cold stadials and Heinrich events, respectively. Low salinity surface water and the sea ice edge spread to the Greenland-Scotland Ridge, and during the largest Heinrich events, probably far into the Atlantic Ocean.

title: Biomarker analyses on sediment core BP00-07/07 from the southern Kara Sea (Arctic Ocean)

description: The Holocene is characterized by the late Holocene cooling trend as well as by internal short-term centennial fluctuations. As Arctic sea ice acts as a significant component (amplifier) within the climate system, investigating its past long- and short-term variability and controlling processes is beneficial for climate future predictions. This study presents the first biomarker-based (IP25 and PIP25) sea ice reconstruction from the Kara Sea (Core BP00-07/07), covering the last 8 ka. These biomarker proxies reflect conspicuous short-term sea ice variability during the last 6.5 ka that is identified unprecedentedly in the source region of Arctic sea ice by means of a direct sea ice indicator. Prominent peaks of extended sea ice cover occurred at ~3, ~2, ~1.3 and ~0.3 ka Spectral analysis of the IP25 record revealed ~400- and ~950-year cycles. These periodicities may be related to the Arctic/North Atlantic Oscillation (AO/NAO), but probably also to internal climate system fluctuations. This demonstrates that sea ice belongs to a complex system that more likely depends on multiple internal forcing.
