Data were generated from analysis of a sinking particle samples collected in a bottom-moored sediment trap deployed at deep sea time series Station M. Samples selected for analysis were associated with anomalous high particulate organic carbon flux events observed over the past 30 years of the time series. The dataset includes bulk fluxes associated with each sample and also the taxonomically resolved fluxes of phytoplankton cells quantified within the samples. Bulk fluxes include those previously reported by Smith et al. (2018) (particulate organic carbon flux, particulate inorganic carbon flux, and mass flux) and new data generated by this study (biogenic silica flux, total cell flux, and the flux of each phytoplankton taxa detected by microscopy). Large episodic pulses of particulate organic carbon (POC) at the deep-sea (~4000 m) time-series Station M in the Northeast Pacific Ocean have increased in frequency and magnitude over the past 32 years. We inferred the ecological drivers of these events by quantifying the phytoplankton and biomineral composition within particles collected by bottom-moored sediment traps immediately before, during, and after 14 high-flux events. Samples collected during high-flux events contained a significantly different phytoplankton community from other sampling periods. These particles contained relatively fewer intact phytoplankton cells and a sustained contribution from fragmented diatom frustules derived from a significantly different diatom community. Biomineral fluxes did not appear to be driving high-flux events. We suggest that most of the observed high-flux events were generated by offshore transport of coastal diatom blooms, but that these particles were also highly transformed by deep sea pelagic foodwebs before reaching bathypelagic depths.

Inorganic carbon was determined using an UIC coulometer and a salt correction was performed by using AgNO3 titration. The PIC was subtracted from the total carbon to calculate the total POC in the samples. Parameter or Variable: Particulate Inorganic Carbon Flux (calculated); Units: mg m^-2 d^-1; Observation Category: sediment trap analysis; Sampling Instrument: McLane Parflux Mark 78H2 sediment trap; Sampling and Analyzing Method: Inorganic carbon was determined using an UIC coulometer and a salt correction was performed by using AgNO3 titration. Parameter or Variable: Biogenic silica flux (calculated); Units: mg m^-2 d^-1; Observation Category: sediment trap analysis; Sampling Instrument: McLane Parflux Mark 78H2 sediment trap; Sampling and Analyzing Method: Biogenic silica contents of sediment trap samples were measured using the protocol by Strickland and Parsons (1977). Biogenic silica within triplicate subsamples were dissolved in a strong base (NaOH) in a hot water bath for 1 hour followed by the addition of ammonium molybdate. Parameter or Variable: Mass flux (calculated); Units: mg m^-2 d^-1; Observation Category: sediment trap analysis; Sampling Instrument: McLane Parflux Mark 78H2 sediment trap; Sampling and Analyzing Method: A known fraction of the sediment trap sample was lyophilized and weighed. Parameter or Variable: Cell number flux (calculated); Units: millions m^-2 d^-1; Observation Category: sediment trap analysis; Sampling Instrument: McLane Parflux Mark 78H2 sediment trap; Sampling and Analyzing Method: Cells within a known fraction of 1 milliliter of diluted sample were counted using a Sedgewick rafter on a Nikon Eclipse Ts2 microscope. A minimum of 400 cells were counted and until at least 80% of the predicted cell types present were identified or until a maximum of 1000 cells were counted. Cell number fluxes were calculated by multiplying cell concentrations in the sample by the total volume of the sample and divided by the collection time and trap collection area. Uncertainty associated with calculated cell fluxes was estimated using a Poisson distribution of the total number of cells counted (the square root of the count number). Parameter or Variable: Sample Name flux (calculated); Units: # cells m^-2 d^-1; Observation Category: plankton; Sampling Instrument: McLane Parflux Mark 78H2 sediment trap, Nikon Eclipse microscope; Sampling and Analyzing Method: Cell fluxes were classified in major functional types including diatoms, coccolithophores, dinoflagellates, and nanoflagellate. The nanoflagellate and dinoflagellate categories likely represent a mixture of both phototrophic and heterotrophic taxa. Cells were often fragmented or missing defining features and we further classified cells to the most specific taxonomic category possible: species, genus, or morphotype. Cell types were further grouped into broader categories if fewer than 5 cells within that type were observed, including a single category for rare cells within each phytoplankton functional type. Fragmented and empty cells that did not contain a chloroplast were included in counts if they could be placed in a cell type category but were recorded distinctly from those cells that contained chlorophyll. Fragmented and empty cells were only classified for diatom categories because cells from all other functional groups appeared to be intact. Cell number fluxes were calculated by multiplying cell concentrations in the sample by the total volume of the sample and divided by the collection time and trap collection area.
