Acoustic presence data on Antarctic blue whales (Balaenoptera musculus intermedia) were obtained from passive acoustic monitoring (PAM) data collected at five different... -
Late Eocene to early Oligocene oxygen and carbon isotope records and biogenic...
The late Eocene through early Oligocene (40-33 Ma) represents a transition from a warm-house to icehouse climate mode, with the expansion of Antarctic glaciation shortly after... -
Authigenic neodymium isotope data of sediment cores from the deep South Atlantic
Here, we present neodymium isotope data (εNd) from three sediment cores from the Atlantic sector of the Southern Ocean (SO) to assess the distribution of water masses during the... -
Microapleontological and geochemical analyses from the Indian sector of the S...
Micropaleontological (coccolith, planktonic foraminifera) and geochemical (CaCO3, CaXRF, δ18O N. pachyderma, δ13C N. pachyderma) analyses from sediment core MD04-2718 retrieved... -
Elemental composition of the Southern Ocean key species Phaeocystis antarctic...
An Fe-Mn bottle addition experiment was conducted in the laboratory to investigate the importance of manganese (Mn) next to iron (Fe) for growth, photophysiological adaptation... -

This data set contains total organic carbon (TOC) contents and stable carbon isotope ratios of bulk carbonate and organic carbon in Early Cretaceous (Barremian-Albian) sediments... -
Radiocarbon, d18O, winter sea ice, and summer sea surface temperature estimat...
This dataset includes radiocarbon, d18O, winter sea ice concentration (wSIC), and summer sea surface temperature (sSST) estimates for marine sediment core TAN1302-96 (59.09°S,... -
Morphotype counts, morphometrical measurements and mass estimations on Emilia...
We studied the distribution of coccoliths in surface sediments across the Drake Passage and calcification of Emiliania huxleyi morphotypes in surface sediment samples retrieved... -
Mesozooplankton abundance, biovolume, size and stoichiometry of the POLARSTER...
Zooplankton samples were collected between 03/26/2018 and 04/27/2018 around the northern tip of the Antarctic Peninsula (63° 0' 1.843'' S, 60° 0' 16.901''W) onboard the RV... -
Phytoplankton species composition under Fe and Mn limitation in the Drake Pas...
This study highlights the importance of manganese (Mn) next to iron (Fe) for growth of specific Southern Ocean phytoplankton groups. Two Fe-Mn bottle amendment experiments with... -
Concentration, accumulation rates, Th fluxes, focusing factors, and productiv...
Changes in Southern Ocean export production have broad biogeochemical and climatic implications. Specifically, iron fertilization likely increased subantarctic nutrient... -
Dissolved iron release from salp and krill fecal pellets and uptake of iron i...
Dataset 1 shows the dissolved iron (dFe) values of an iron release experiment performed in the Southern Ocean at the tip of the Western Antarctic Peninsula. Krill and salp fecal... -
Diatom-bound nitrogen isotope and TEX86L-SST records of MD12-3394 and MD11-3353
Previous studies suggest that, during the late Pleistocene ice ages, surface-deep exchange was somehow weakened in the Southern Ocean's Antarctic Zone (AZ), reducing the leakage... -
Salp biology (Salpa thompsoni) at the Chatham Rise, New Zealand
The abundant pelagic tunicate Salpa thompsoni is a major grazer in the Southern Ocean. We report the length-frequency distribution, maturity stage composition, growth, and... -
