Stable carbon and nitrogen isotopic ratios of cores from the Bering Sea, supplement to: Nakatsuka, Takeshi; Watanabe, Kazuki; Handa, Nobuhiko; Matsumoto, Eiji; Wada, Eitaro (1995): Glacial to interglacial surface nutrient variations of Bering Deep Basins recorded by d13C and d15N of sedimentary organic matter. Paleoceanography, 10(6), 1047-1061

Takeshi Nakatsuka, Kazuki Watanabe, Nobuhiko Handa, Eiji Matsumoto & Eitaro Wada
Stable carbon and nitrogen isotopic ratios (d13C and d15N) of organic matter were measured in three sediment cores from deep basins of the Bering Sea to investigate past changes in surface nutrient conditions. For surface water reconstructions, hemipelagic layers in the cores were distinguished from turbidite layers (on the basis of their sedimentary structures and 14C ages) and analyzed for isotopic studies. Although d13C profiles may have been affected by diagenesis, both d15N and d13C...

Sedimentology on two cores from Scoresby Sund, Greenland, supplement to: Marienfeld, Peter (1992): Postglacial sedimentary history of Scoresby Sund, East Greenland. Polarforschung, 60(3), 181-195

Peter Marienfeld
Reconstruction of the postglacial palaeoenvironmental evolution was the main objective of marine geological investigations in the Scorcsby Sund fjord system. For this purpose, samples of marine sediments, taken on RV Polarstern cruises ARK-V/3b and ARK-VII/3b in 1988 and 1990, have been analysed. All investigated fjord sediments are paratills. However, remarkable changes in sediment fabric and composition occur with depth in cores. They are attributable to different modes of sediment deposition. Therefore, a subdivision of the...

Mineralogy and structural specification of ODP Leg 125 peridotite samples, supplement to: Girardeau, Jacques; Lagabrielle, Yves (1992): Deformation history of peridotites from Mariana Forearc, conical seamount, Leg 125. In: Fryer, P; Pearce, JA; Stokking, LB; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 125, 519-532

Jacques Girardeau & Yves Lagabrielle
Abundant serpentinite seamounts are found along the outer high of the Mariana forearc at the top of the inner slope of the trench. One of them, Conical Seamount, was drilled at Sites 778, 779, and 780 during Leg 125.The rocks recovered at Holes 779A and 780C, respectively, on the flanks and at the summit of the seamount, include moderately serpentinized depleted harzburgites and some dunites. These rocks exhibit evidence of resorption of the orthopyroxene, when...

Age determinations of rocks from Vestfjella and Ahlmannryggen in Antarctica, supplement to: Peters, Matthias; Lippolt, Hans Jürgen; Rittmann, Ursula; Weber, Klaus (1989): Field relations, petrography and K-Ar Age determinations on Magmatic Rocks from Neuschwabenland, Antarctica. Polarforschung, 59(1/2), 35-44

Matthias Peters, Hans Jürgen Lippolt, Ursula Rittmann & Klaus Weber
The Proterozoic country rock at Ahlmannryggen consists of flat lying basaltic lo andesitic lava flows and sedimentary rocks intruded by dioritic sills (Borgmassivet Intrusives). The suites display a typical platform cover. K-Ar age determinations gave maximum ages of about 1200 Ma on the magmatic rocks. All these suites were intruded bv Proterozoic dikes dated also at about 1200 Ma. Localiy the Proterozoic rocks have a slaty cleavage grading into mylonitic texture which strike parallel to...

Swath sonar bathymetry during POLARSTERN cruise ANT-XXII/1 (PS67) with links to multibeam raw data files

Fred Niederjasper & Hans Werner Schenke
Multibeam data were collected during R/V Polarstern cruise ANT-XXII/1. Data recording was executed in Atlantic Ocean from Ampère Seamount to Cape Town for calibration of sonar system Hydrosweep DS2 in HDBE mode. Data are unprocessed and may contain outliers and blunders. For that reasons the data should not be used for high quality grid calculations and charting projects. One file contains a measurement period not exceeding eight hours. The dataset consists of 50 files in...

Hans Werner Schenke, Rike Rathlau, Bettina Platten & Andreas Winkler
Multibeam data were collected during R/V Polarstern cruise ARK-XX/3. Data recording was executed in Fram Strait Region. Data are unprocessed and may contain outliers and blunders. Therefore the data should not directly be used for grid calculations and charting projects but need to be edited furthermore. One file contains a measurement period not exceeding eight hours. The dataset consists of 78 files in ATLAS SURF format which are compressed with GZIP to size of 796...

Swath sonar bathymetry during POLARSTERN cruise ANT-XVII/4 (PS56) with links to multibeam raw data files

Fred Niederjasper, Andreas Beyer, Martin Klenke, Thomas Ohff & Hans Werner Schenke
Multibeam data were collected during R/V Polarstern cruise ANT-XVII/4. Data recording was executed on transit from Punta Arenas to Porcupine Seabight where systematic profiling was performed. Data are unprocessed and may contain outliers and blunders. Therefore the data should not directly be used for grid calculations and charting projects but need to be edited furthermore. Because of a hardware problem the time stamps within the files are erroneously increased by one day. This error was...

(Table 2) Production parameters of phytoplankton and some associated parameters in the area of the Titanic Polygon, supplement to: Vedernikov, Vladimir I; Gagarin, Vladimir I (2003): Primary production and chlorophyll in the frontal zone of the Gulf Stream and Labrador Current in July-September 2001. Translated from Okeanologiya, 2003, 43(2), 209-218, Oceanology, 43(2), 196-205

Vladimir I Vedernikov & Vladimir I Gagarin
Studies were carried out mostly in the area of RMS Titanic wreck site (41°44'N, 49°57'W) located above the continental slope and the south of the Grand Banks of Newfoundland. In a period from 18.06 to 24.09.2001 five surveys of production characteristics of surface phytoplankton were conducted over 5-9 days. Mean values of these characteristics obtained during the surveys were 9.2-11.7 mg C/m**3 per day for primary production (C_phs), 0.102-0.188 mg/m**3 for chlorophyll a (C_chls), and...

Biomarkers of early Aptian sediments of the Shatsky Rise, supplement to: Dumitrescu, Mirela; Brassell, Simon C (2005): Biogeochemical assessment of sources of organic matter and paleoproductivity during the early Aptian Oceanic Anoxic Event at Shatsky Rise, ODP Leg 198. Organic Geochemistry, 36(7), 1002-1022

Mirela Dumitrescu & Simon C Brassell
This study investigates organic-rich sedimentary sequences deposited during the early Aptian Oceanic Anoxic Event (OAE1a) at Sites 1207 and 1213 on Shatsky Rise (ODP Leg 198) in the west-central Pacific. Biomarker analyses provide evidence of the algal and bacterial origin of organic matter (OM) in these sediments where the abundance of steroidal components, particularly sterenes and sterones, suggests that the OM includes major contributions from eukaryotic sources in an environment characterized by high phytoplankton productivity....

Zooplankton community within the Titanic Polygon, Northwest Atlantic, summer 2003, supplement to: Vinogradov, Georgy M; Musaeva, Eteri I; D'yakonov, Vladimir Yu; Gagarin, Vladimir I (2004): Vertical distribution of zooplankton in the area of the frontal zone of the Gulf Stream and subpolar waters (Titanic test area) in the summer 2003. Translated from Okeanologiya, 2004, 44(2), 249-258, Oceanology, 44(2), 230-239

Georgy M Vinogradov, Eteri I Musaeva, Vladimir Yu D'yakonov & Vladimir I Gagarin
In summer 2003 we continued our long-term series of observations over the zooplankton community within the Titanic Polygon (area of the frontal zone of Gulf Stream and the Labrador Current) in the North Atlantic, where interaction of ecosystems of subpolar and warm waters takes place. Depending on hydrological situation occurring in the frontal zone interrelated interannual variations in abundance and biomass of plankton species including Calanus hyperboreus and mesopelagic shrimps of Acanthephyra genus were observed....

Seawater carbonate chemistry and biological processes of zooplankton Amphiascoides atopus and Schizopera knabeni during experiments, 2010, supplement to: Pascal, Pierre-Yves; Fleeger, J W; Galvez, Fernando; Carman, Kevin R (2010): The toxicological interaction between ocean acidity and metals in coastal meiobenthic copepods. Marine Pollution Bulletin, 60(12), 2201-2208

Pierre-Yves Pascal, J W Fleeger, Fernando Galvez & Kevin R Carman
Increased atmospheric CO2 concentrations are causing greater dissolution of CO2 into seawater, and are ultimately responsible for today's ongoing ocean acidification. We manipulated seawater acidity by addition of HCl and by increasing CO2 concentration and observed that two coastal harpacticoid copepods, Amphiascoides atopus and Schizopera knabeni were both more sensitive to increased acidity when generated by CO2. The present study indicates that copepods living in environments more prone to hypercapnia, such as mudflats where S....
