Summary: | Sediment core LV63-41-2 (52°34' N, 160°01' E; water depth: 1924 m) was recovered from the NW Pacific off the Kamchatka Peninsula during the Russian–Chinese joint expedition on R/V Akademik M.A. Lavrentyev in 2013. The length of the core is 467 cm.ChlorinChlorin content is assumed to reflect changes in primary surface ocean productivity because continental-derived chlorophyll contributes insignificantly to its composition in deep marine sediment (Harris et al., 1996). The chlorin content in core LV63-41-2 was measured by a Shimadzu UV-1650PC spectrophotometer at 1 cm resolution, using the same analytical reagents and pretreatment procedures proposed by Harris et al. (1996).Total organic and inorganic carbon contentsTotal organic carbon (TOC) and inorganic carbon contents (CaCO3) in core LV63-41-2 were measured at every 2 cm throughout the core by coulometry using an AN-7529 analyzer in the same way, which has been reported by Gorbarenko et al. (1998). TOC content was determined by calculating the difference ... |
