On the Preservation of Laminated Sediments Along the Western Margin of North America
[1] Piston, gravity, and multicores as well as hydrographic data were collected along the Pacific margin of Baja California to reconstruct past variations in the intensity of the oxygen-minimum zone (OMZ). Gravity cores collected from within the OMZ north of 24 N did not contain laminated surface sediments even though bottom water oxygen (BWO) concentrations were close to 5 mmol/kg. However, ma...
متن کاملClimate cyclicity in late Holocene anoxic marine sediments from the Seymour–Belize Inlet Complex, British Columbia
An 8.72 m late Holocene sediment core (VEC02A07) obtained from Alison Sound in the Belize–Seymour Inlet Complex of central British Columbia, Canada was deposited between ∼3500–1000 yr BP under primarily anoxic marine conditions. This core contains a detailed cyclic record of land–sea interactions as evidenced by significant fluctuations in marine primary productivity and changes in the supply o...
متن کاملEarly Holocene decadal - scale ocean variability recorded in Gulf of California laminated sediments
Scanning electron microscope examination of Holocene laminated sediment from Guaymas Basin, Gulf of California, resolves up to five depositional events per year. Each lamina/sublamina of an early Holocene section of continuously laminated sediment was recorded from backscattered electron imagery photomosaic analysis. Diatom mat laminae, composed predominantly of Thalassiothrix longissima, are a...
متن کاملNortheast US precipitation variability and North American climate teleconnections interpreted from late Holocene varved sediments.
A more thorough understanding of regional to hemispheric hydroclimate variability and associated climate patterns is needed in order to validate climate models and project future conditions. In this study, two annually laminated (varved) sediment records spanning the last millennium were analyzed from Rhode Island and New York. Lamination thickness time series from the two locations are signifi...
متن کاملCalcareous Nannofossils in Holocene Surface Sediments of the Persian Gulf
The effect of the paleoclimatic and paleoenvironmental changes on the structure of the bioticcommunities are stronger and better recorded in the shelf area than in the open sea. The present study isdevoted to impact of climatic events on some species of calcareous nannofossils. For this reason, 17samples of surface sediments of the Persian Gulf were studied. Preservation of calcareous nannofoss...
