Solar radiation is the primary energy source for surface planetary life, so that pigments are fundamental components of any surface-dwelling organism. They may therefore have evolved in some form on […]
The launch of a new journal is appropriately like a space mission. It is the result of a scientific need, the inspiration of a group of committed scientists and technologists, […]
The routine use of spectrophotometry on the sediment surfaces of archive halves of each section during the onboard sedimentological core description process is a great stride toward development of real-time […]
This paper describes a unique record of glacier flow instability for East Greenland during the Little Ice Age. Trace metal analysis of sediment cores collected during 1998 from the Noret […]
Diversity and structure of copepod assemblages were investigated using 259 WP2 zooplankton samples collected from the top 200 m of the Atlantic Ocean between 60°N and 63°S. Whilst richness at […]
Experimental observations have shown photochemical production in the upper layers of firn. We use a modeling approach for Antarctica in summer, calculating the actinic flux in snowpack, and estimating NOX […]
An expanded Oligocene-Miocene boundary interval recovered in the Cape Roberts Project CRP-2A core from beneath the Ross Sea, Antarctica, has yielded a high-resolution integrated chrono stratigraphy that has, in turn, […]
Hydrothermal alteration in volcanic arcs occurs in many settings and may involve magmatic, marine, lacustrine or groundwaters, driven by magmatic, tectonic or thermal events. King George Island, part of the […]
NO, NOy (total reactive nitrogen oxides), gaseous HNO3, and particulate nitrate (p-NO3−) were measured at Neumayer Station from February 1999 to January 2000. In addition, during February 1999, the NOy […]
Analytical estimates of resistivity due to electrostatic current-driven ion-acoustic waves are compared with Vlasov simulation results. Particular attention is given to the case of similar ion and electron temperatures that […]
