Miocene Biomarker Temperature and CO2 Estimates from DSDP Site 94-608, supplement to: Super, James R; Thomas, Ellen; Pagani, Mark; Huber, Matthew; O'Brien, Charlotte; Hull, Pincelli M (2018): North Atlantic temperature and pCO2 coupling in the early-middle Miocene. Geology, 46(6), 519-522

James R Super, Ellen Thomas, Mark Pagani, Matthew Huber, Charlotte L O'Brien & Pincelli M Hull
Climate proxies indicate coupling between changes in atmospheric pCO2, global temperatures and ice volume over much of the Cenozoic. Evidence has been presented for decoupling of these factors in the Miocene, though the cause of the apparent decoupling was uncertain. Here, we revisit Deep Sea Drilling Program (DSDP) Site 608 (24-9 Ma) in the North Atlantic, to provide improved constraints on sea surface temperatures (SSTs) using the TEX86 and Uk'37 proxies, and use these to...

Abundance and distribution of planktonic Copepoda in the Southern Ocean and other regions from 1980 to 2005, supplement to: Cornils, Astrid; Sieger, Rainer; Mizdalski, Elke; Schumacher, Stefanie; Grobe, Hannes; Schnack-Schiel, Sigrid B (2018): Copepod species abundance from the Southern Ocean and other regions (1980 - 2005) - a legacy. Earth System Science Data, 10, 1457-1471

Astrid Cornils & Sigrid B Schnack-Schiel
This data collection originates from the efforts of Sigrid Schnack-Schiel (1946–2016), a zooplankton ecologist with great expertise in life cycle strategies of Antarctic calanoid copepods, who also investigated zooplankton communities in tropical and subtropical marine environments. Here, we present 33 data sets with abundances of planktonic copepods from 20 expeditions to the Southern Ocean (Weddell Sea, Scotia Sea, Amundsen Sea, Bellingshausen Sea, Antarctic Peninsula), one expedition to the Magellan region, one latitudinal transect in the...

In situ measured oxygen profiles from station PS85/476-1 (HG I) within the HAUSGARTEN area (Fram Strait) in 2014 (POLARSTERN cruise PS85)

Ralf Hoffmann, Ulrike Braeckman & Frank Wenzhöfer
During PS85 (in 2014) and PS93.2 (in 2015) autonomous benthic lander were deployed at the HAUSGARTEN stations HG I and HG IV. The lander was equipment with a profiler unit, which holds electrochemical, needly type oxygen sensors in order to measure oxygen profiles across the sediment-water interface. By using the profiles, the diffusive oxygen uptake was calculated via the decrease in the oxygen concentration in the Diffusive Boundary Layer (DBL). For a further description of...

Total oxygen fluxes in the HAUSGARTEN area (Fram Strait) in 2014 (POLARSTERN cruise PS85)

Ulrike Braeckman & Ralf Hoffmann
For ex situ total oxygen uptake (TOU) measurements, sediment cores recovered by a MUC were used. The sediment cores were closed airtight with no air bubbles in the overlying water. The distance between the SWI and the edge of the lid was measured for volume calculations of the overlying water. An optical oxygen microsensor (Pyroscience, Aachen, Germany) with a tip size diameter of 50 µm was installed in the lid, allowing a continuous measurement of...

Photographs of tiles at time series station Liliguapi, Paso Comau, Patagonia, Chile, at 2016-03-22

Jürgen Laudien, Günter Försterra & Verena Häussermann
This dataset was generated in the frame of the co-operation between the Huinay Scientific Field Station (http://www.huinay.cl) and the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research (http://www.awi.de). If you intend to work with this data set please do not hesitate to contact the authors to discuss cooperation possibilities.The backside of common tiles was selected as substrate. Tiles have the following dimensions, length:height = 15:15 cm (225 cm2) and are fixed with two...

Different Mid-Pleistocene transition analysis from IODP Site 306-U1314, supplement to: Hernández-Almeida, Iván; Sierro, Francisco Javier; Flores, José-Abel; Cacho, Isabel; Filippelli, Gabriel M (2013): Palaeoceanographic changes in the North Atlantic during the Mid-Pleistocene Transition (MIS 31-19) as inferred from planktonic foraminiferal and calcium carbonate records. Boreas, 42(1), 140-159

Iván Hernández-Almeida, Francisco Javier Sierro, José-Abel Flores, Isabel Cacho & Gabriel M Filippelli
Marine sediments from the Integrated Ocean Drilling Project (IODP) Site U1314 (56.36°N, 27.88°W), in the subpolar North Atlantic, were studied for their planktonic foraminifera, calcium carbonate content, and Neogloboqudrina pachyderma sinistral (sin.) δ13C records in order to reconstruct surface and intermediate conditions in this region during the Mid‐Pleistocene Transition (MPT). Variations in the palaeoceanography and regional dynamics of the Arctic Front were estimated by comparing CaCO3 content, planktonic foraminiferal species abundances, carbon isotopes and ice‐rafted...

Seawater carbonate chemistry and physiological performance parameters of Carcinus maenas under respective incubation conditions

Bastian Maus, Christian Bock & Hans-Otto Pörtner
Ocean acidification causes an accumulation of CO2 in marine organisms and leads to shifts in acid-base parameters. Acid-base regulation in gill breathers involves a net increase of internal bicarbonate levels through transmembrane ion exchange with the surrounding water. Successful maintenance of body fluid pH depends on the functional capacity of ion-exchange mechanisms and associated energy budget. For a detailed understanding of the dependence of acid-base regulation on water parameters, we investigated the physiological responses of...

Seawater carbonate chemistry and the amount of reads gained from small RNA sequencing of Anemonia viridis, supplement to: Urbarova, Ilona; Patel, Hardip; Forêt, S; Karlsen, Bard Ove; Jørgensen, Tor Erik; Hall-Spencer, Jason M; Johansen, Steinar D (2018): Elucidating the Small Regulatory RNA Repertoire of the Sea Anemone Anemonia viridis Based on Whole Genome and Small RNA Sequencing. Genome Biology and Evolution, 10(2), 410-426

Cnidarians harbor a variety of small regulatory RNAs that include microRNAs (miRNAs) and PIWI-interacting RNAs (piRNAs), but detailed information is limited. Here, we report the identification and expression of novel miRNAs and putative piRNAs, as well as their genomic loci, in the symbiotic sea anemone Anemonia viridis. We generated a draft assembly of the A. viridis genome with putative size of 313 Mb that appeared to be composed of about 36% repeats, including known transposable...

Seawater carbonate chemistry and community structure of marine biofouling communities, supplement to: Brown, Norah E M; Milazzo, Marco; Rastrick, S P S; Hall-Spencer, Jason M; Therriault, Thomas W; Harley, Christopher D G (2018): Natural acidification changes the timing and rate of succession, alters community structure, and increases homogeneity in marine biofouling communities. Global Change Biology, 24(1), e112-e127

Ocean acidification may have far-reaching consequences for marine community and ecosystem dynamics, but its full impacts remain poorly understood due to the difficulty of manipulating pCO2 at the ecosystem level to mimic realistic fluctuations that occur on a number of different timescales. It is especially unclear how quickly communities at various stages of development respond to intermediate-scale pCO2 change and, if high pCO2 is relieved mid-succession, whether past acidification effects persist, are reversed by alleviation...

Hemipelagic and turbiditic deposits constrain lower Bengal Fan depositional history through Pleistocene climate, monsoon, and sea level transitions, supplement to: Weber, Michael E; Reilly, Brendan T (2018): Hemipelagic and turbiditic deposits constrain lower Bengal Fan depositional history through Pleistocene climate, monsoon, and sea level transitions. Quaternary Science Reviews, 199, 159-173

Michael E Weber & Brendan T Reilly
The Bengal Fan contains the most complete record of Himalayan climate and tectonics. As the largest fan system of the world it is fed by the Ganges-Brahmaputra river systems. International Ocean Discovery Program (IODP) Expedition 354 retrieved seven sites along an east-west core transect at 8°N in the lower Bengal Fan. We studied the Pleistocene sections of these sites to provide constraints on the depositional history of the last 1.25 Ma. Lowresolution bio- and magnetostratigraphic...
