Comparison of the accuracy of SST estimates by artificial neural networks (ANN) and other quantitative methods using radiolarian data from the Antarctic and Pacific Oceans
Gupta, S.M.; Malmgren, B.A. (The society of Earth Scientists, 2009)The quality of quantitative estimates of sea surface water temperatures (SSTs) is evaluated for different techniques, Imbrie-Kipp transfer functions (IKTF), the modern analog technique (MAT), weighted-averaging partial ... -
Quaternary carbonate record from the equatorial Indian Ocean and its relationship with productivity changes
Naidu, P.D.; Malmgren, B.A. (Elsevier, 1999)The CaCO sub(3) content in Quaternary deep-sea sediments from Pacific and Atlantic oceans have been suggested to respond differently to glacial/interglacial cycles; CaCO sub(3), contents are highest during glacials in ... -
Sea surface temperature changes during May and August in the western Arabian Sea over the last 22 kyr: Implications as to shifting of the upwelling season
Godad, S.P.; Naidu, P.D.; Malmgren, B.A. (Elsevier, 2011)In the western Arabian Sea (WAS), the highest seasonal sea surface temperature (SST) difference presently occurs between May and August. In order to gain an understanding on how monsoonal upwelling modulates the SST ... -
Seasonal sea surface temperature contrast between the Holocene and last glacial period in the western Arabian Sea (Ocean Drilling Project Site 723A): Modulated by monsoon upwelling
Naidu, P.D.; Malmgren, B.A. (AGU, 2005)Annual, summer, and winter sea surface temperatures (SSTs) in the western Arabian Sea were reconstructed through the last 22 kyr using artificial neural networks (ANNs) based on quantitative analyses of planktic foraminifera. ...
