Large Multidecadal Salinity Trends near the Pacific–Antarctic Continental Margin

Modeling Sedimentary Deposits on the Continental Margin

A first objective is to investigate the fabric (pattern) of seabed stratification on continental margins at small time and space scales (1 cm-50 cm depth into the seabed; 1 hr-3 yrs sedimentary record). To this end, we are testing the hypothesis that on muddy shelves such as the northern California shelf, Holocene event stratigraphy consists of the deposits of high-concentration storm regimes a...

New reconstruction of Antarctic near-surface temperatures: Multidecadal trends and reliability of global reanalyses

A reconstruction of Antarctic monthly mean near-surface temperatures spanning 1958–2012 is presented. Its primary goal is to take advantage of a recently revised key temperature record fromWestAntarctica (Byrd) to shed further light on multidecadal temperature changes in this region. The spatial interpolation relies on a kriging technique aided by spatiotemporal temperature covariances derived ...

Salinity and Climate Reconstructions from Continental Lakes

Tectonic inheritance at a continental margin

GSA Today: v. 16, no. 2, doi: 10.1130/1052-5173(2006)016<4:TIAACM>2.0.CO;2 INTRODUCTION Forty years ago, the eastern margin of North America inspired Tuzo Wilson (1966) to ask, “Did the Atlantic close and then re-open?” The Wilson cycle of closing and opening of ocean basins incorporates the cyclic assembly and breakup of supercontinents. Alternate processes of extension and compression of cont...

Geochemistry and Thermobarometry of Bazman volcanic rocks, An example of active continental margin volcano

  Bazman volcano is located in the Makran-Chaghi magmatic arc in southeastern Iran. Many studies have been done on this volcano, especially of petrology such as: Biabangard and Mollazadehbarvati, 2017; Berberian and Berberian, 1982; Mohammadi, 2005; Sahandi et al., 2010; Schmidt and Dabiri, 2019; Firoozkoohi, et al., 2017; Ghodsi et al., 2006; Glamghash et al., 2015; Karimpour et al., 2012; St...
