Barnett, P.R.O. & Hardy, B.L.S. (1967). A diver-operated quantitative<br />

sampler for sand macrofaunas. Helgolander wiss. Meeresunters, 15,<br />

390-398. [Sampler in two parts - 1) sample cylinder (I.D. 35.7 cm;<br />

sampling area 0.1 m 2 ) pushed into sand at first by hand, then by<br />

pressure difference as air replaces water in cylinder, 2) air-lift<br />

pump used to remove contents of cylinder after lid removed]<br />

(I.D. 35.7 cm, sampling area 0.1 m 2 ) sinks into bottom by pressure<br />

difference created when air replaces water in cylinder, then air-lift<br />

used to remove sediment containing animals. See also Zoutendyk (1971)]<br />
