This dataset contains a compilation of observed fluxes of sinking particulate material (particulate organic carbon or POC, particulate inorganic carbon or PIC, and biogenic silica or bSi) at five ocean time-series sites obtained from sediment traps and radioisotopes. The five time-series sites were selected upon abundance of data on a monthly and depth basis. The sites are: Equatorial Pacific Process Studi (EqPac) in the upwelling region of the equatorial Pacific Long-Term Ecological Research observatory HAUSGARTEN, in the eastern Fram Strait, off Svalbard, at the Atlantic-Arctic boundary. Ocean Station Papa (OSP), in the southern portion of the Alaska Gyre in the NE subarctic Pacific Porcupine Abyssal Plain time-Series Observatory (PAP-SO), in the NE Atlantic off the SW of the UK Bermuda Atlantic Time-Series/Oceanic Flux Program joint site (BATS/OFP), in the northern Sargasso Sea, in the subtropical NW Atlantic The compilation contains a total of 7013 data points, where BATS/OFP accumulates 50% of all of them, followed by OSP (28%), HAUSGARTEN (10%), PAP-SO (10%) and EqPac (2%). The bulk of the collected data is in the euphotic zone and POC flux has a higher count than PIC and bSi. The origin of the 98% of the data is sediment traps, the remaining 2% (157 data points) are surface fluxes derived from radioisotopes.
