“…B, and so forth. Each family was assigned to a single functional group among those defined by Fauchald and Jumars (1979), as detailed in Laguionie-Marchais et al (2013) and in Table 2. Table 2 Three-letter code key of polychaete functional groups as defined by Fauchald and Jumars (1979 …”

“…As Jeffreys et al (2013) used a different sampler, it is not possible to ascribe the presence of Spionidae to either a reduced bow-wave effect or an increase of opportunistic surface deposit feeders under enrichment conditions as observed in other deep-sea systems (Levin et al, 1999;Smith and Hessler, 1987). On abyssal plains, greater numbers of surface deposit feeders have previously been linked to higher POC flux (Laguionie-Marchais et al, 2013).…”

“…When comparing Sta. M and the Porcupine Abyssal Plain (NE Atlantic), Laguionie-Marchais et al (2013) suggested that the difference in Spionidae relative abundance might be at least partly explained by differences in surface productivity and consequently POC flux to the seafloor. Members of the family Spionidae have previously been noted for their occurrence in organically enriched sediments (Grassle and Morse-Porteous, 1987).…”

“…M, the macrofauna is dominated by polychaetes that varied between 1991-2005 in terms of total density, family and functional group compositions, and in family rank abundance distributions (RADs; Laguionie-Marchais et al, 2013). The latter authors showed that potential relationships between POC flux and polychaete assemblage attributes were complex.…”

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Changes in several species were also lagged to changes in POC flux by 4 to 10 months. The polychaete fauna exhibited a significant positive relationship between total density and total energy use rate, suggesting population-level tracking of a common resource (e.g. POC flux food supply). Neither compensatory nor energetic zero-sum dynamics were detected among the polychaete assemblage, but the results suggest that the latter occur in the macrofaunal community as a whole. The results do indicate (a) potential control of species composition, and the density of individual key species, by food supply, when the time-series prior to the sampling location was analysed separately, and (b) generally sensitive detection of environmental change by species-level analysis of the abyssal polychaete assemblage.

“…A large portion of this material was composed of upper water column plankton exuviae, fecal pellets and carcasses (Wilson et al 2013). The sediment community infauna is largely composed of foraminifera, nematodes, nemerteans, polychaetes and crustaceans (Drazen et al 1998;Laguionie-Marchais et al 2013;Ruhl et al 2008). The microbial community is dominated by Crenarchaeota (Moeseneder et al 2012) and Gammaproteobacteria (Kouridaki et al 2010).…”

Decadal Change in Sediment Community Oxygen Consumption in the Abyssal Northeast Pacific

Long time-series studies are critical to assessing impacts of climate change on the marine carbon cycle. A 27-year time-series study in the abyssal northeast Pacific (Sta. M, 4000 m depth) has provided the first concurrent measurements of sinking particulate organic carbon supply (POC flux) and remineralization by the benthic community. Sediment community oxygen consumption (SCOC), an estimate of organic carbon remineralization, was measured in situ over daily to interannual periods with four different instruments. Daily averages of SCOC ranged from a low of 5.0 mg C m
