We undertook an interlaboratory comparison of techniques used to extract and analyze trapped gases in ice cores. The intercomparison included analyses of standard reference gases and samples of ice from the Greenland Ice Sheet Project 2 (GISP2) site.

Ice core data from Yukon and Greenland spanning from ∼1750 to 1950 indicate that between ∼1850 and ≤1910 a clear atmospheric signal exists of an episodic biomass burning event that is referred to as the Pioneer Agriculture Revolution. This is b

2,3,7,8-Tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) was measured in sediments and suspended matter samples from estuaries adjacent to an industrial site in Newark, NJ, where chlorinated phenols had been produced. Present day and recent historical leve

To assess the magnitude and extent of 2,3,7,8-TCDD contamination, sediment cores from the Newark Bay estuary and contiguous waters were collected and dated by radiochemical methods. The core sections from two time horizons were analyzed for selected

The most conspicuous feature of the record of past climate contained in polar ice is the rapid warming which occurs after long intervals of gradual cooling. During the last four transitions from glacial to interglacial conditions, over which such abr
