The TRAMS samplers were attached on the steel wires in series similar to the Niskin bottle
hydrocast; however, each TRAMS sampler automatically extended a long (~1 m) polyethylene suction tube toward the horizontal direction upstream from the hydrocast wire just before the sampling, in order to avoid contamination from the wire.
Suspended sediment concentration measured with OBS-3A and Niskin Bottle
in four sites (A, B, C and D) in a cross section of the Mira River near the aqueduct intake of Tumaco City (Figs.
Water samples were collected using a 5-L Niskin bottle
at a depth of 2 m because of greater biomass in the surface water.
Twenty-one water samples from depth and surface were collected on three separate days by lowering a niskin bottle
on a line at three coordinates along a South to North transect.
Chan's most important instruments include a Niskin bottle
, which traps salt water beneath the surface in a canister and is then hauled back to the boat.
At each station, seawater and hydrothermal plume samples were collected at different depths with a conductivity, temperature, and depth (CTD) aluminum rosette (Seabird) containing 2410 L Niskin bottles
. These stations were operated as on-line measurements with a Seabird 911 CTD coupled to a Carousel water sampler SBE 32.
