Sampling in the Marine Environment

Ready to depart for an exciting day on the high seas. Coastal waters research vessel. Note boom and winch used to lower sampling devices over the side of the boat.

Clam-shell grab sampler for collecting seafloor sediment samples. Lowering grab sampler over the side of the boat.

Reading the reversing thermometers

Deploying the Niskin bottle The Niskin bottle is made of plastic and teflon and is used to collect water samples for metal analysis. Niskin bottle in the open configuration. When the messenger hits the white rod it releases the cables and the ends of the bottle (plumbers helpers) snap shut.

Secchi disk deployed at a depth of 1 meter. Making measurements using the Forel color scale.
