A recent Oceanography feature article, “New Frontiers in Ocean Exploration” highlights an expedition to maintain, upgrade and expand over 24 instruments at Ocean Networks Canada’s (ONC) offshore cabled observatory.
Several McLane samplers were among the instruments maintained by the E/V Nautilus team during the 14-day expedition. The samplers’ ongoing deployments are part of key experiments and long-term monitoring at the Endeavour site.
A RAS-500 and a PPS deployed together as a paired instrument collect time-series samples during a year-long period for eDNA experiments. Experiments have provided new data on temporal changes and ecosystem biodiversity at hydrothermal vent sites.
Additionally, continuous long-term monitoring at Endeavour is performed with Sediment Traps. Samples record sediment deposits from regular sedimentation, resuspension of sediments, and earthquakes and provide data on sediment processes and benthic interactions.

The PPS collects 24 individual filtered individual in situ particulate water samples onto 47mm filters. A fixative value option can treat samples with reagents for preservation.
The RAS collects collects 48 samples of 500mL or 100mL each ambient water and suspended material in bags, isolating the samples for subsequent laboratory analysis.
Sediment Traps collect vertically settling particles into 13 or 21 individual sample bottles of 500mL or 250mL ea, which are sealed when not in collection mode.
