For each topic, the problem is identified, its magnitude and causes reviewed using selected examples, and an update on methods to correct for the potential bias or minimize the problem using new technologies is presented. To minimize hydrodynamic biases due to flow over the trap mouth, the use of neutrally buoyant sediment traps is encouraged. The influence of swimmers is best minimized using traps that limit zooplankton access to the sample collection chamber. New data on the impact of different swimmer removal protocols at the US time-series sites HOT and BATS are compared and shown to be important. Recent data on solubilization are compiled and assessed suggesting selective losses from sinking particles to the trap supernatant after collection, which may alter both fluxes and ratios of elements in long term and typically deeper trap deployments. 2007 published Journal of Marine Research 65 3 Sears Foundation for Marine Research 345-416 TRUE 0022-2402 http://jmr.publisher.ingentaconnect.com/content/jmr/jmr/2007/00000065/00000003/art00002 5898 3 3984 1 application/pdf en staffonly
