Antarctic Paleogene planktonic foraminifera
ODP Leg 113 drilled the first nearly continuous pre-Neogene calcareous biogenic sequence from the Antarctic Ocean at Sites 689 and 690. At 65∞S, these are probably the highest... -
Calcium carbonate concentrations of ODP Sites 113-689 and 113-690
An almost continuous Upper Cretaceous through Pleistocene biogenic sediment section was recovered from two sites on Maud Rise, a volcanic edifice in the Weddell Sea, off eastern... -
Upper Cretaceous-Paleogene stratigraphy of ODP Sites 113-689 and 113-690
This contribution summarizes the biostratigraphy of planktonic foraminifers, calcareous nannofossils, and benthic foraminifers, in combination with the magnetostratigraphy,... -
Stable isotopic composition and carbonate concentrations of sediments of the ...
Stable isotopic records across the Cretaceous/Paleogene (K/P) boundary in Maud Rise Holes 689B and 690C indicate that significant climatic changes occurred during the latest... -
Isotopic composition and Strontium/Calcium ratios of foraminifera of ODP Hole...
Oxygen and carbon isotopic ratios were measured from Maestrichtian benthic and planktonic foraminifer species and bulk carbonate samples from ODP Sites 689 and 690, drilled on... -
Consolidation tests of ODP Leg 113 samples
Examination of the geotechnical characteristics of Weddell Sea, Maud Rise, and South Orkney microcontinental margin sediments recovered during ODP Leg 113 reveals that the... -
Amino acids in the interstitial waters from ODP Hole 113-695A
Site 695 lies on the southeast margin of the South Orkney microcontinent on the northern margin of the Weddell Sea, at 62°23.48'S, 43°27.10'W in 1305 m water depth. The... -
Geochemical studies of the Cretaceous-Tertiary boundary in ODP Holes 113-689B...
In a study of ODP Hole 689B no iridium (Ir) anomaly was found in Sections 1 through 6 of Core 25X or in Core 26X from the top down to section 2, 3-12 cm. The background Ir... -
Interstitial-water chemistry of ODP Leg 113 sites
Variations in the distribution of major elements and stable oxygen isotopes in ODP Leg 113 pore water are not related to lithology and thus appear to be controlled by minor... -
Grain shape of sediment from the Weddell Sea
Very fine quartz sand was examined from Paleogene and Neogene sediments of ODP Sites 693, 694, 695, 696, and 697 to determine their grain roundness using Fourier analysis and... -
Geochemistry of basalts from ODP Hole 113-690C
Basalts from Maud Rise, Weddell Sea, are vesicular and olivine-phyric. Major, trace, and rare earth element concentrations are similar to those of alkali basalts from ocean... -
Siliceous sponge spicules from ODP Leg 113
Siliceous sponge spicules are present throughout many of the sections drilled by Ocean Drilling Program Leg 113. The assemblages consist mostly of monaxons and occur in Eocene... -
Cenozoic silicoflagellates and ebridians from ODP Leg 113
Silicoflagellates are present at ODP 113 Sites 689, 690, 693, 695, 696, and 697. These are generally Neogene in age except for Oligocene and Eocene silicoflagellates and... -
Middle Miocene to Recent radiolarians from the Weddell Sea
Well preserved middle Miocene to Recent radiolarians were recovered from several sites in the Weddell Sea by ODP (Ocean Drilling Program) Leg 113. Low rates of sedimentation,... -
Oligocene to middle Miocene radiolarians of Maud Rise, Weddell Sea
At Sites 689 and 690, drilled during ODP (Ocean Drilling Program) Leg 113 on the Maud Rise (southeast Weddell Sea), moderately to well preserved radiolarian assemblages were... -
Bolboforma of Eocene and lower Oligocene sediments of Maud Rise, Weddell Sea
Five species of Bolboforma have been found in middle Eocene to lower Oligocene sediments from Maud Rise, Weddel Sea, Antarctica (Leg 113, Holes 689B and 690B), the first... -
Paleocene to middle Eocene calcareous nannofossils of Maude Rise, Weddell Sea
Cores from Sites 689 and 690 of Ocean Drilling Program Leg 113 provide the most continuous Paleocene and Eocene sequence yet recovered by deep sea drilling in the high latitudes... -
Sporomorphs and dinoflagellate cysts of ODP Leg 113 holes
Palynological studies were carried out on Paleogene sections from Sites 693 and 696 of Ocean Drilling Project Leg 113 in the Weddell Sea region. Dinoflagellate cysts and... -
Maestrichtian through Neogene benthic foraminifers of Maud Rise
Upper abyssal to lower bathyal benthic foraminifers from ODP Sites 689 (present water depth 2080 m) and 690 (present water depth 2941 m) on Maud Rise (eastern Weddell Sea,... -
Maestrichtian calcareous nannofossils of MAud Rise, Weddell Sea
Recovery of an essentially complete upper Maestrichtian/lower Paleocene interval on Maud Rise at 65 °S latitude in the Weddell Sea during Ocean Drilling Program Leg 113 marks...
