A suite of organic biomarkers was examined in six sediment cores from two shelf-basin transects in the Chukchi and Beaufort Seas of the Arctic Ocean to compare the sources and preservation of organic carbon between the two differing depositional regimes. Profiles of polyunsaturated fatty acids (PUFA

## Abstract Nitrogen (N) and phosphorus (P) dynamics in the Kuparuk River in arctic Alaska were characterized in a 3βyear study using routine samples near the mouth of the river at the Arctic Ocean, synoptic wholeβriver surveys, and temporally intense sampling during storms in three headwater basin
The provenance of organic matter in sediments from the Mackenzie River and Beaufort Shelf was investigated using the stable carbon and radiocarbon isotopic compositions of bulk organic matter and the stable carbon isotopic compositions of individual organic compounds, including lignin-derived phenol
Molecular organic biomarkers together with trace element composition were investigated in sediments east of Barrow Canyon in the western Arctic Ocean to determine sources and recycling of organic carbon in a continuum from the shelf to the basin. Algal biomarkers (polyunsaturated and short-chain sat
