As hypothesized, SOD was negatively correlated with water depth and positively correlated with both surface-sediment pigment concentration and macrofaunal biomass, with macrofaunal biomass explaining approximately 74% of the variability in SOD. We propose that higher macrofauna-normalized respiration rates (i.e., SOD divided by macrofaunal biomass) in deep water indicate that microbial\u0096meiofaunal respiration predominates in deep versus shallow water. Finally, deeper stations associated with Barrow Canyon had SODs, benthic macrofaunal biomass, and surface-sediment pigment concentrations that were similar to those of shallower shelf locations, suggesting down-canyon transport of organic material. <\/jats:p>","DOI":"10.1139\/f05-102","type":"journal-article","created":{"date-parts":[[2005,9,14]],"date-time":"2005-09-14T15:18:39Z","timestamp":1126711119000},"page":"1756-1765","source":"Crossref","is-referenced-by-count":63,"title":["Impacts of water depth, sediment pigment concentration, and benthic macrofaunal biomass on sediment oxygen demand in the western Arctic Ocean"],"prefix":"10.1139","volume":"62","author":[{"given":"Lisa M","family":"Clough","sequence":"first","affiliation":[]},{"given":"Paul E","family":"Renaud","sequence":"additional","affiliation":[]},{"given":"William G","family":"Ambrose Jr.","sequence":"additional","affiliation":[]}],"member":"155","reference":[{"key":"p_1\/p_1_1","doi-asserted-by":"crossref","first-page":"4411","DOI":"10.1029\/94JC01982","volume":"100","author":"Ambrose W.G., Jr.","year":"1995","journal-title":"J.
