| Popis: |
To assess fluxes of particles sinking through the deep open ocean, a large sediment trap has been developed. The trap opening is 1.5 m 2 and contains 94 hexagonal baffle cells. Sediment particles are collected in the receiving cup at the bottom of the trap, which is open at both ends as it sinks to the designated depth. The receiving cup moves into alignment with the funnel automatically to collect the sediment. At the end of deployment an electrical signal again moves the receiving cup to seal the sample and leave the funnel open at both ends while the trap is recovered. Sodium azidesodium chloride solutions diffuses through a series of membrane filters into the sample to poison it. We have deployed and recovered 18 traps for as long as 110 days at depths up to 5600 m. |
