TITLE: Palmer LTER: Hydrogen peroxide in the Palmer-LTER region: II. Water column distributions. AUTHORS: J Resing, G Tien, R Letelier, DM Karl, D Jones Palmer LTER Contribution No. 20 During the 1992-1993 field season, we had the unique opporutnity to study the seasonal variability of H2O2 in the surface waters of the Palmer long-term ecological research (LTER) study region. In excess of 1,000 water samples were collected from 64 degrees S to 68 degrees S. Repeat hydrographic surveys were conducted on three separate cruises aboard the R/V Polar Duke (PD92-09, November 1992, and PD93-01, January and February 1993) and R/V Nathaniel B. Palmer (NBP93-02, March through May 1993).
