We examined the composition and flux of particles sinking to the deep Eastern Tropical Pacific from 2003 to 2013. We examined the composition and flux of particles sinking to the deep Eastern Tropical Pacific from 2003 to 2013. We observed that the flux of particulate organic and inorganic carbon to a depth of 4,950 m increased as the climate variability called the “Pacific Decadal Oscillation” shifted from a positive to negative phase (i.e., more La Niña events) in 2008. The Korea Institute of Ocean Science and Technology (KIOST) has maintained a long-term monitoring station in the ETP (Station KOMO; 10.5°N and 131.2°W) since 2003 to investigate the biogeochemical cycling of organic carbon.

Samples were collected monthly from July 2003 to July 2013. The trap mooring array was recovered and redeployed once a year. Sinking particles were also collected intermittently at depths of 1,200 m from September 2009 to June 2010 and 4,500 m from August 2008 to February 2013.; Data Quality Method: Each trap sample was split into five equal aliquots using a McLane wet sample divider (WSD-10). Three aliquots were rinsed with ultrapure (Milli-Q) water, freeze-dried, and weighed for gravimetric determination of total particle flux. Total particulate carbon content was determined using an elemental analyzer (Carlo-Erba 1110 CNS) with a precision of <1.2% relative standard deviation (RSD). Particulate inorganic carbon (PIC) content was analyzed using a total inorganic carbon analyzer (UIC CO2 coulometer; model CM5014) with <1% RSD. POC content was estimated as the difference between total carbon and inorganic carbon contents. A direct de-carbonation method using sulfurous acid was also used for determination of POC contents of a set of samples (n = 9; < 0.5% RSD). Both methods agreed within 0.4%. Biogenic opal content was determined following a sequential alkaline leaching method with <3% RSD. The proportion of lithogenic material was estimated from the difference between total particulate mass and the sum of the biogenic components, that is, organic matter (twice the weight of organic carbon), CaCO3, and biogenic opal. Planktonic foraminifera flux was determined by picking individual foraminifera tests under the microscope (Zeiss Stemi SV 11; 10) and weighing. The presence of coccoliths was verified by examination under the microscope. Coccolithophore flux was estimated as the difference between the CaCO3 and foraminifera fluxes. Parameter or Variable: Net Primary Production (calculated); Units: mgC m-2day-1; Observation Category: model output; Sampling Instrument: VGPM; Sampling and Analyzing Method: Net primary production (NPP) was estimated from 9 km resolution monthly satellite chlorophyll data using the Vertically Generalized Production Model (VGPM) (Behrenfeld and Falkowski, 1997). The model is based on a temperature-dependent description of MODIS chlorophyll-specific photosynthetic efficiency, which utilizes day length, surface chlorophyll-a concentration, SST, and photosynthetically available radiation (www.science.oregonstate.edu/ocean.productivity).; Data Quality Method: The median value of NPP in the 1° × 1° grid box surrounding our study site was taken to examine biological activity in the ETP. asNeeded Metadata are developed, maintained and distributed by NCEI.
