    • Small larvacean species are often very abundant in near-surface waters. Most have bodies less than 10mm long, with house diameters commonly twice as large. Their houses may be produced at a rate of six or more each day, depending on the density of food particles. Discarded small houses are important components of organic aggregate flux in the ocean's upper layers, but they rarely reach the deep sea floor (34-36).

    • Sediment traps catch what they were designed to catch, namely, small, slowly sinking particles. Although sediment traps may occasionally collect sinker fragments, physical contact, particularly with traps that have interior baffles, is certain to exclude, disrupt, or disperse this material (16). The easily recognized rectangular mesh structures of larvacean filters have not been repoted in analyses of sediment trap contents.

    • Bathochordaeus sp. is found chiefly at depths from 100 to 300 m; Mesochordaeus erythrocephalus occurs principally between 300 and 500 m (77, 28).

    • This value considerably exceeds the amount of flux estimated by Silver, Coale, Pilskaln, and Steinberg (16), for Bathochordaeus in the same region. Although our measurements of the abundance and turnover of houses and sinkers agree, our measurements of the carbon content of sinkers are substantially greater, principally because of incomplete sampling in the earlier study.
