摘要：

We have designed, constructed and tested a trace element clean sampling device for long term deployment (6 months or longer) on deep-sea moorings. The device collects unfiltered 500 ml samples by opening and closing a bottle originally filled with dilute acid (passively replaced by denser seawater). Each sample is collected by an independent module, so failure of a single unit does not affect others. Seven years of deployments have refined the sampler into a rugged and reliable device. The device also can be hung below a wire to collect water column samples. Automated trace element sampler (ATE), a spinoff from moored in situ trace element serial sampler, is a single-module device for allowing trace metal clean near-surface samples to be collected by personnel not trained in trace element sampling. ATE/VANE, another variation, allows the same personnel to collect upper water column profiles on conventional hydrowire. The systems have been tested by comparing samples collected for lead and iron with those collected by previously proven sampling techniques. (C) 2003 Elsevier Science Ltd. All rights reserved.
