Pollen record and landscape reconstruction of the small forest-steppe natural archive Oskino-09

Eleonora Yuzhanina, Natalia Ryabogina & Sergey Ivanov
Lacustrine-peat sediments from the small forest-steppe natural archive Oskino-09, spanning about 7000 years were studied by pollen method. Radiocarbon dating was obtained for four samples; the age of the deposits was determined using the Bhron age model. In the southwest of Western Siberia, meadow-steppe landscapes occupied the largest areas in the middle of the Holocene 7.5-4.7 cal ka BP because of reduced effective moisture due to warming. A subsequent gradual decrease in temperatures and a...

Antiphased dust deposition and productivity in the Antarctic Zone over 1.5 million years

Michael E Weber
The Southern Ocean paleoceanography provides key insights into how iron fertilization and oceanic productivity developed through Pleistocene ice-ages and their role in influencing the carbon cycle. We report the first high-resolution record of dust deposition and ocean productivity for the Antarctic Zone, close to the main dust source, Patagonia. Our deep-ocean records cover the last 1.5 Ma, thus doubling that from Antarctic ice-cores. We find a 5 to 15-fold increase in dust deposition during glacials...

Ceilometer cloud base height from station Ny-Ålesund (2017-08 et seq)

Marion Maturilli
Clouds are a key factor for the Arctic amplification of global warming, but their actual appearance and distribution are still afflicted by large uncertainty. On the Arctic-wide scale, large discrepancies are found between the various reanalyses and satellite products, respectively. Although ground-based observations by remote sensing are limited to point measurements, they have the advantage of obtaining extended time series of vertically resolved cloud information. The presented data set provides cloud base height measured by...

Rita Melo Franco-Santos, Holger Auel, Maarten Boersma, Marleen De Troch, Martin Graeve, Cédric Léo Meunier & Barbara Niehoff
The two experiments for which data is presented in this record were conducted in the context of RMFS' PhD work. The objective of the experiments was to quantify and qualify the effects of diet quality, herein manipulated in terms of different species (the diatom Conticribra weissflogii and the dinoflagellate Oxyrrhis marina) grown under different nutrient regimes (nutrient replete and Nitrogen-depleted), on the fatty acid (FA) assimilation and turnover of the copepod Temora longicornis.Experiments used field-collected...

Laboratory friction experiments on natural samples from IODP site U1520

Agathe Eijsink & Matt J Ikari
The northern Hikurangi subduction margin hosts slow slip events (SSEs), which are exceptionally shallow (<15 km). The sedimentary sequence on the incoming plate is therefore representative of the shallow fault material where the SSEs will take place once they enter the subduction zone. Knowledge about the frictional behavior of these sediments is required to know which lithologies are capable of hosting SSEs, and what mechanisms are causing them. Frictional behavior is material-specific and depends on...
