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...

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...

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...

Creator:: Barday, Robert James
Abstract:: In order to quantitatively examine the crustal structure of the Panama Basin without the benefit of local seismic refraction data, the following assumptions were made: (1) No significant lateral changes in density take place below a depth of 50 km. (2) The densities of the crustal layers are those of...

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...

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...

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...

Creator:: Zaneveld, J. Ronald, Spinrad, Richard W., Menzies, David W., Oregon State University. School of Oceanography, and Nederlands Instituut voor Onderzoek der Zee
Abstract:: Hydrographic and optical measurements were made in situ in the Congo River and the Angola Basin during May 1978. These measurements were made by members of the optical oceanography group at Oregon State University in cooperation with scientists from the Netherlands Institute for Sea Research. The data taken by the...
