Abstract
  • In January-February 2001, we measured microbial biomass as ATP and community respiration as ETS activity of organisms < 200 ?m in the aphotic zone of the Ross Sea. Microbial respiration amounted to 2.14 mmol C m - 2 day- 1 in the depth range 200-1000 m. Our daily estimates of carbon export are close to the daily percentage of net community production (NCP), removed as sinking biogenic particles from the upper 100 m in the entire Ross Sea, but lower than those of other oceanic systems. Comparing remineralization determined in this study with that obtained by sediment traps in the Ross Sea, it appeared that about 63% of organic carbon remineralized by respiration derived from POC pool. Such evidence highlighted POC source as the main organic fuel of the biological pump in the Ross Sea. (literal)
