Monothalamous foraminifera from West Spitsbergen fjords, Svalbard: a brief overview
During the 2004 summer season, 14 sediment samples were collected in Kongs− fjorden and Isfjorden, West Spitsbergen, from 6 down to 345 m water−depth (mwd). The samples yielded abundant assemblage of monothalamous foraminifera, belonging to almost 40 morphotypes. Our qualitative (>125 μm) and quantitative data (125–500 μm) allowed to distinguish three water−depth related assemblages in both Kon...
متن کاملTriassic Stratigraphy in the Zuni Mountains, West-central New Mexico
—The Triassic System in the Zuni Mountains consists of one Middle Triassic unit, the Moenkopi Formation, the Upper Triassic Chinle Group, and the Upper Triassic-Lower Jurassic(?) Wingate Sandstone. The Chinle Group in the Zuni Mountains consists of six formations, in ascending order: Zuni Mountains (named here; = “mottled strata” of previous workers), Shinarump, Bluewater Creek, Petrified Fores...
متن کاملRelationships between development of organic−rich shallow shelf facies and variation in isotopic composition of pyrite (Middle Triassic, Spitsbergen)
51 samples from the Middle Triassic black shales (organic carbon−rich silt− stones; up to 4.9% TOC – Total Organic Carbon) from the stratotype section of the Bravaisberget Formation (western Spitsbergen) were analyzed with respect to isotopic composition of pyritic sulphur ( 34S) and TOC. Isotopic composition of syngenetic py− rite−bound sulphur shows wide ( 34S from −26‰ to +8‰ VCDT) and narro...
متن کامل99Tc in seawater in the West Spitsbergen Current and adjacent areas.
99Tc levels were measured in seawater samples collected between 2000 and 2002 in the West Spitsbergen Current (WSC) and along the western coast of Svalbard or Spitzbergen and compared with available oceanographic 3-D modelling results for the late 1990s. Additional data from related regions are also presented in order to support the data interpretation. The seawater in the Arctic fjord Kongsfjo...
متن کاملLomonosovfonna and Holtedahlfonna ice cores reveal east – west disparities of the Spitsbergen environment since AD 1700
An ice core extracted from Holtedahlfonna ice cap, western Spitsbergen, record spanning the period 1700–2005, was analyzed for major ions. The leading empirical orthogonal function (EOF) component is correlated with an index of summer melt (log([Na]/[Mg]) from 1850 and shows that almost 50% of the variance can be attributed to seasonal melting since the beginning of the industrial revolution. T...
