Geographic focus of research:

Brief synopsis of current research:
Dr. Pedersen's interests encompass a broad spectrum within sedimentary marine and lacustrine geochemistry. Current research focuses on the following areas:
1) palaeoceanography, in which both chemical variability in sediments and stable carbon, oxygen and nitrogen isotopic analysis of carbonates and organic matter are used as forensic tools to determine how the ocean behaved in the past;
2) controls on the accumulation, burial, preservation, and composition of organic matter in open-ocean and continental margin sediments;
3) diagenetic reactivity of submerged mine tailings deposits in lakes and fjords;
4)controls on the diagenetic mobility of trace metals in polluted and unpolluted coastal marine sediments.
