The miniaturized sampling system for AUVs, ROVs, moorings and gliders

The Deep Water Sampler allows for the collection of up to 26 grab samples at depths of 300m (shallow), 1500m (deep), 3000m (ultra-deep) or 6000 m (extreme) using miniaturized peristaltic pump (PP) technology.

Easy to install on any autonomous underwater vehicle or mooring system, this versatile equipment can be deployed in a variety of configurations and allows for a wide range of sampling strategies, as the vials can be equipped with different types of filters or be pre-filled with various preservatives or biocides.

Returning in-situ samples to the surface allows for subsequent laboratory analysis (complete fingerprinting of hydrocarbon traces, full ocean chemistry, microbiology and metagenomics), as well as verification of in-line sensor measurements (e. g. WiMo/WiSens physicochemical probes).

Sampling can be done in real time or pre-programmed, from sensors or by remote control. For autonomous applications in shallow waters, the sampler can be equipped with a battery and a programmable control module.


A versatile instrument, the Deep Water Sampler can be used in a wide range of applications:

  • Studying oceans chemistry and acidification
  • Collecting water quality baselines around offshore industrial facilities
  • Observing deep water pollution plumes
  • Fingerprinting of hydrocarbon traces
  • Performing microplastics pollution research
  • Acquiring samples for oceanographic biology research, e. g. metagenomics and microplankton studies
  • Performing scientific exploration of remote or inaccessible locations
  • Studying subsea hydrothermal sources

Main benefits

  • Modular design for easy mounting on any underwater glider, autonomous underwater vehicle (AUV), remotely operated vehicle (ROV) or mooring system
  • Programmable and remotely controllable equipment by applying a sampling protocol or via a software interface
  • Constant buoyancy throughout the deployment due to pressure balancing
  • Addition of a collector rinsing system, which guarantees representative sampling without cross-contamination (optional)
  • Easy adaptation to most platforms in terms of number of vials and physical configuration of the equipment
  • Extended deployment with Power-down and deep-sleep modes
  • Easy maintenance and conditioning in the field between sampling campaigns
