https://www.pangaea.de/ information publisher tableDigital The objective of expedition PS133 performed from October to December 2022 was to understand the sources and pathways of input and transport of Fe and other nutrients into South Georgia Island shelf waters and further downstream in the Southern Antarctic Circumpolar Current (10°W to 42°W). The aim of the sub-project Island Impact - Understanding the regional impact of islands (South Georgia) on Southern Ocean biogeochemistry and ecosystem function was to determine the nutrients phosphate, nitrate, silicate, nitrite and ammonia in water samples from the entire water column in order to obtain nutrient sections through the POLARSTERN PS133.1 cruise. Water samples were taken by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV POLARSTERN. Samples were measured in duplicate with a SEAL AA500 autoanalyzer system using SEAL methods based on Grasshoff et al., 1983, with the exception of ammonia based on a fluorometric determination developed by Kerouel, R. and Aminot, A. (1997). In Continuous flow systems a peristaltic pump delivers samples and reagents into a long heated glass tube, which acts as the reaction vessel. Air bubbles are regularly introduced into the flow to minimize dispersion and maintain a steady state. The specific product formed during the reaction with the species to be determined is normally detected with spectrophotometers at a specific wavelength. Samples were measured and validated against Certified Reference Material (CRM) 7602a and 7603a provided by JAMSTEC (Japan). completed Ludwichowski, Kai-Uwe
