Iodine was discovered as a novel element in 1811 during the Napoleonic Wars. To celebrate the bicentennial anniversary of this event we reflect on the history and highlight the many facets of iodine research that have evolved since its discovery. Iodine has an impact on many aspects of life on Earth as well as on human civilization. It is accumulated in(More)
Oxygen depletion in the upper ocean is commonly associated with poor ventilation and storage of respired carbon, potentially linked to atmospheric CO2 levels. Iodine to calcium ratios (I/Ca) in recent planktonic foraminifera suggest that values less than ∼2.5 μmol mol(-1) indicate the presence of O2-depleted water. Here we apply this proxy to estimate past(More)
Information, in the form of data and services, pervasively resides in the vast number of nodes in wireless ad hoc networks and sensor networks. To obtain these data and services from the hosting nodes, two procedures, peer discovery and data routing, are executed. Nodes that contain desired data/services are first discovered through peer discovery. After(More)
Road salt used as a deicing agent in winter months has become an emerging contaminant to streams and groundwater. In central New York, road salts are applied heavily during winter months. Recognizing potential sources of salinity to a river may reveal processes controlling the salinization of freshwater systems, with implications for future management(More)
We report iodine and bromine concentrations in a total of 256 samples of pore waters collected from all nine sites of ODP Leg 204, Hydrate Ridge. In a subset of these samples, we have also determined iodine ages in the fluids using the cosmogenic isotope I (T1/2 = 15.7 Ma). The presence of this cosmogenic isotope combined with the strong association of(More)
High-volume hydraulic fracturing (HVHF) gas-drilling operations in the Marcellus Play have raised environmental concerns, including the risk of groundwater contamination. Fingerprinting water impacted by gas-drilling operations is not trivial given other potential sources of contamination. We present a multivariate statistical modeling framework for(More)

at the Hanford Site, U.S.: Iodate Incorporation into Calcite” T study reports iodate incorporation in precipitates found in degassed groundwater samples and in precipitates formed in laboratory experiments. These results could have very important implications in remediation of I-129 contamination in natural environments. However several aspects about the(More)
