Geochemistry of sediments from the continental slope of the Ross Sea, Antarctica
A sediment core, collected from the western part of the continental slope of the Ross Sea at 2380 m water depth, records events of the last two climatic cycles (250 kyr). A... -
Silicate in marine sediments from the Emerland Basin, North Atlantic
A method was developed to measure porosity and dissolved interstitial silicate at millimeter intervals or less in a sediment core. In cores from Emerald Basin (Scotian Shelf),... -
Radionuclides in sediment cores of the Atlantic sector of the Southern Ocean
We present time series of export productivity proxy data including 230Thex-normalized deposition rates (rain rates) of 10Be, dissolution-corrected biogenic Ba, and biogenic opal... -
Abundance of calcareous nannofossils in sediments of the Fram Strait
Sediment cores from the Fram Strait are dated by means of calcareous nannofossil biostratigraphy and are shown to represent, at the most, the last 300 kyr (oxygen isotope stages... -
Biogenic silica in the coastal plume of the Mississippi River
The surface distributions of dissolved silicic acid, chlorophyll and diatom abundance were measured in the plume of the Mississippi River and adjacent waters during spring (late... -
Barium in seawater and sediments from the Artic Ocean
As part of ongoing circulation studies in the Arctic, seawater samples for dissolved Ba concentrations were obtained during Sep.-Oct., 1992 at several locations in the Bering... -
Chemistry of eastern tropical Atlantic porewater
Distributions of pore water O2, NO-2, NO-3, NH+4, Si(OH)4, PO[3-]4, Mn[2+], F-, and T.A. were determined at 15 stations in the eastern equatorial Atlantic. While overall profile... -
Particle flux determined from traps in the Canary Island region
We present a 3 year record of deep water particle flux at the recently initiated ESTOC (European Station for Time-series in the Ocean, Canary Islands) located in the eastern... -
Sedimentology and Th, Pa, U, and N isotopic composition of core MD84-527
High-resolution records of opal, carbonate, and terrigenous fluxes have been obtained from a high-sedimentation rate core (MD84-527: 43°50'S; 51°19'E; 3269 m) by normalization... -
Sedimentology on cores from the Bellingshausen und Amundsen seas
Surface sediments from the Antarctic continental margin in the Bellingshausen and Amundsen seas (Pacific sector of the Southern Ocean) were investigated in order to decipher... -
Sedimentology, organic geochemistry, and stable isotopes of core PS2138-1
We studied variations in terrigenous (TOM) and marine organic matter (MOM) input in a sediment core on the northern Barents Sea margin over the last 30 ka. Using a multiproxy... -
Investigation of sediment core PS2556 from Bellingshausen Sea, Antarctica
Die Rekonstruktion der glaziomarinen Sedimentationsprozesse am antarktischen Kontinentalrand des westlichen Bellingshausenmeeres erfolgte durch die sedimentologische Auswertung... -
Biogenic opal, carbonat concentrations and stable oxygen isotope ratios of fo...
We present records of biogenic opal percentage and burial rate in 12 piston cores from the Atlantic and Indian sectors of the Southern Ocean. These records provide a detailed,... -
Pelagic phosphorus accumulation in the Pacific Ocean
As a limiting nutrient to marine life, phosphorus (P) is an effective tracer of today's marine productivity. The distribution of P in marine sediments likewise tracks the... -
Sedimentation at Manop Site H in the eastern equatorial Pacific
Gravity cores recovered from Manganese Nodule Project site H (6°33'N, 92°49'W) show marked downcore variations in the abundance of calcium carbonate, organic carbon, opal,... -
Chemistry of pore water from Arctic sediments
Pore water and solid phase distributions of C, N, P and Si in sediments of the Arctic Ocean (Svalbard area) have been investigated. Concentrations of organic carbon (Corg) in... -
Organic carbon and opal in deep sea sediments of the southern and eastern Wed...
During the ANT V14 (1986187) and ANT V113 (1987188) cruises of R.V. Polarstern sedirnents from the eastern, southern and central Weddell Sea were sarnpled with a boxcorer andlor... -
Flux data in the Greenland Basin
Pelagic processes and their relation to vertical flux have been studied in the Norwegian and Greenland Seas since 1986. Results of long-term sediment trap deployments and... -
Sediment record of the last 1.8 Ma in the Amundsen Sea
Records of glaciomarine deposition recovered from the West Antarctic continental margin in the Amundsen Sea allow the reconstruction of the behaviour of the West Antarctic Ice...
