High-resolution mapping with an autonomous underwater vehicle (AUV) of a section of the San Clemente fault, offshore Southern California, reveals the largest documented cold-seep-associated barite deposits discovered to date. Although barite deposits

Several correlatable layers of sediment, rich in ice rafted grains, have been documented in the North Atlantic. The most notable within the last glacial cycle are the Heinrich layers, layers extremely rich in ice rafted detritus and generally barren

The sources of ice-rafted debris (IRD) from Heinrich layer 3 (H 3) in the North Atlantic were studied by means of Pb isotopic analyses of single- and multiple-grain samples of ice-rafted feldspars from core V28-82 (49° 27′N, 22° 16′W). Pb ratio

40Ar/39Ar ages of most single ice-ratted amphiboles from Heinrich layer 2 (H2) from a core in the Labrador Sea, a core in the eastern North Atlantic and a core in the western North Atlantic range from 1600 to 2000 Ma. This range is identical to that

A model is used to evaluate the relative importance of temperature, soil pCO2, and organic acidity on silicate weathering rates in an average soil of warm temperate climate. The model has a structure similar to the Model of Acidification of Groundwat
