Abstract:
The NSF-supported research icebreaker Nathaniel B. Palmer operates year-round in support of the U.S. Antarctic Program, carrying out global change studies in biological, chemical, physical, and oceanographic disciplines.
This data set consists of underway data from leg NBP0205 on the R/V Nathaniel B. Palmer. This leg started at Punta Arenas, Chile and ended at Punta Arenas, Chile.
Quality
Sample of melting snowbanks, stream and lake waters were collected in January and February 2002 from ice-free areas of northern Victoria Land. Temperature, pH and conductivity were measured on the site using portable meters. Bottles were brought back to the laboratory of Terra Nova Bay and stored at 20 degrees C for transport to Italy. In the Siena University laboratories samples were melted and immediately analyzed. Analysis of Major cations (Ca2+, Mg2+, Na+, K+ and NH4+) and anions (Cl-, NO3- and SO42-) was carried out by ion chromatography (IC) using a Dionex DX-120 ion chromatograph.
