Surface sediments of the Panama Basin : coarse components

Creator:: Kowsmann, Renato O.
Abstract:: The abundance and distribution of biogenic, terrigenous and volcanic particles in the Panama Basin are markedly dependent on bottom topography and dissolution of calcite in the deeper parts of the basin. Of the coarse fraction (>62μ), foraminiferal tests and acidic volcanic glass shards are concentrated on the Cocos and Carnegie...

Holocene accumulation rates of pelagic sediment components in the Panama Basin, Eastern Equatorial Pacific

Creator:: Swift, Stephen Atherton
Abstract:: Holocene bulk sediment and component accumulation rates were measured in twenty-eight piston and gravity cores taken from the floor of the western Panama Basin and on the surrounding ridges. Radiocarbon ages and oxygen isotope curves provided Holocene age control in nine cores. Time datums in nineteen other cores were inferred...

Model of late Pleistocene-Holocene variations in rate of sediment accumulation : Panama Basin, eastern equatorial Pacific

Creator:: Pisias, Nicklas G.
Abstract:: The assumption of constant quartz accumulation for the deep-sea sediment core Y69-106P, taken in the Panama Basin, has been used to date the core and construct a sedimentation rate versus time curve for it. Stratigraphic control for the calculated time scale includes three carbon-14 measurements, the extinction of the radiolarian...

Changing export production in the Eastern Equatorial Pacific, 160 ka to present

Creator:: Kish, Stacy W.
Abstract:: The increase in modern atmospheric CO₂ concentration (360 ppm) from pre-industrial levels (280 ppm) raises concern over the impact of anthropogenic carbon dioxide input on atmospheric chemistry. For this reason, it is important to understand the natural fluctuations of atmospheric carbon dioxide in the past. The Vostok ice core record...
Resource Type:: Masters Thesis
Full Text:: proxies were measured in a set of sediment cores from the Panama Basin and the surrounding deep Pacific

Hydrographic, chemical and optical observations from legs 4 and 5, YALOC-71

Creator:: Plank, William S., Anderson, James J. (James Jay), and Pak, Hasong
Abstract:: Hydrographic, chemical and optical data collected on legs 4 and 5 (November and December, 1971) of YALOC-71 in the vicinity of the Panama Basin are presented. The measurements were made for two purposes--to study the behavior of the Cromwell Current near the Galapagos Islands and to study the suspended particulate...

Sedimentation within the Cocos Gap, Panama Basin

Creator:: Dowding, Lynn Gretton
Abstract:: The Cocos Gap is a deeper portion, or saddle, of the Cocos Ridge and forms part of the western boundary of the Panama Basing It is probably typical of saddles within most submarine ridges, In order to determine the mechanisms controlling sediment dispersal, the nature and sources of the sediments...

Contribution of cold seep barite to the barium geochemical budget of a marginal basin

Creator:: McQuay, Erica L.
Abstract:: Large barite (BaSO4) structures mark cold seeps in the southern San Clemente Basin. Barium flux to San Clemente sediments is two to three times greater than fluxes measured in surrounding California Borderland basins. Analyses of sediment trap material, water column samples, sediments and pore water indicate that expected bariumbearing mineral...
Resource Type:: Masters Thesis
Full Text:: study, a sediment trap mooring array was deployed in the basin from December 2003 to December 2004
