Reconstruction of neogene sea surface temperatures in Ceara Rise (South Atlantic) based on alkenones
(2016-05-19)
The Ceara Rise is a seismic peak located in the Atlantic Ocean and receives both marine and terrigenous sediments. These sediments are important for understanding the paleoclimatic and paleo-environmental conditions in the ...
Repeated Near-Collapse of the Pliocene Sea Surface Temperature Gradient in the North Atlantic
(American Geophysical Union, 2020)
Sea surface temperature (SST) is used to infer past changes in the state of the climate system. Here we use a combination of newly generated and published organic paleothermometer records, together with novel high-resolution ...
Temporal changes in phytoplankton productivity over the last ∼200 years recorded from mejillones bay laminated sediments Sedimentos laminados de la bahía mejillones como registro de cambios temporales en la productividad fitoplanctónica de los últimos ∼20
(2009)
We analyzed the contents of total organic carbon, biogenic opal, chlorins, and alkenones (as productivity proxies) from a laminated sediment core recovered within Bahía Mejillones, northern Chile, in order to reconstruct ...
Coastal cooling and increased productivity in the main upwelling zone off Peru since the mid-twentieth century
(Wiley, 2011)
We reconstructed a high-resolution, alkenone-based sea surface temperature (SST) record spanning the last ca. 150 years, from a sediment core retrieved within the main upwelling zone off Peru. A conspicuous SST decline is ...
Coastal cooling and increased productivity in the main upwelling zone off Peru since the mid‐twentieth century
(American Geophysical Union, 2011-04-14)
We reconstructed a high‐resolution, alkenone‐based
sea surface temperature (SST) record spanning the last
ca. 150 years, from a sediment core retrieved within the
main upwelling zone off Peru. A conspicuous SST
decline ...
Lipid biomarkers in surface sediments from an unusual coastal upwelling area from the SW Atlantic Ocean
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The coastal upwelling off Cabo Frio (SE Brazilian coast, SEBC) represents an exception to the world`s oceans since the majority of the upwelling areas are located in eastern boundary current systems. Cabo Frio represents ...
Centennial-Scale SE Pacific Sea Surface Temperature Variability Over the Past 2,300 Years
(John Wiley and Sons Inc., 2019)
Detailed temperature reconstructions over the past 2,000 years are important for contextualizing modern climate change. The midlatitude SE Pacific is a key region in this regard in terms of understanding the climatic ...
Siliceous microorganisms in the upwelling center off Concepción, Chile (36°S): Preservation in surface sediments and downcore fluctuations during the past ~ 150 years
(Elsevier, 2012)
We analyzed the temporal patterns of siliceous microorganisms in the water column and their representation
in the underlying surface sediments between September 2002 and November 2005, at a fixed station
on the shelf off ...
Reconstrucción de la temperatura superficial a ambos lados del istmo de Panamá entre 4 y 10 millones de años
(Universidad de los AndesGeocienciasFacultad de CienciasDepartamento de Geociencias, 2019)
En el presente estudio se realiza una reconstrucción paleoclimática de las temperaturas superficiales del mar (SST) en el Océano Pacífico y el Mar Caribe a partir de núcleos sedimentarios ODP 1241 y ODP 999, respectivamente. ...
