Deployment of a piston core sampling device used to collect long sediment sample cores during an autumn 2006 cruise onboard NIWA vessel Tangaroa. Like a gravity corer, the piston core device comprises a long metal pipe to collect sediment samples, and a weighted head. In the picture, the pipe is seen extending over the side of the ship. When the end of the corer reaches the seabed, a piston is fired which forces the metal pipe down into the sediment. Using this forced method, long sediment cores - some as long as 15m or 20m - can be recovered and brought back up to the ship.

Multicore sampling device used to collect sediment samples during an autumn 2006 cruise onboard NIWA vessel Tangaroa. The multicorer is so called because, at each deployment site, the device collects more than one sediment core. Individual core pipes are seen in the image as plastic tubes. When the feet of the tripod-like frame hit the seabed, the mass block that is visible towards the top of the tripod is triggered and pushes the array of sampling tubes into the seafloor sediment.

NIWA and VIMS personnel inspect a Gomex box core device during February 2010 fieldwork. Box corers descend to the seabed under the weight of gravity. They are rectangular in shape as shown inside the metal frame legs, and are designed to collect a large volume of sediment from a relatively large surface area. Rotating jaws, also seen in the photograph, close off the bottom of the box after it enters the sediment. Penetration is usually limited to a few 10s of centimetres.

Tripod deployment operations funded by MARGINS. Here, a multi-instrumented tripod is being manoeuvered using Revelle's aft A-frame. An instrument package that includes optical and acoustic backscatter devices, upward-looking ADCP and a CTD is visible in the middle of the tripod. Poverty Bay, New Zealand.

This CTD frame houses a rosette of large, grey Niskin bottles and is ready for deployment in the MARGINS Waipaoa New Zealand focus site. As the frame is lowered through the water column, the bottles are triggered to open and close at specific depths to allow the collection of water samples. Digital instruments on the frame also collect temperature and conductivity data. Image courtesy of JP Walsh, ECU.

A gravity core is used to collect samples of sediments from the upper levels of the seafloor, as in this work for the MARGINS Source-to-Sink initiative in the New Zealand focus site. The gravity corer device comprises a long metal pipe usually lined with a plastic sleeve and typically 4 inches in diameter, and heavy masses which are visible at the top of the picture. It descends through the water column under its own weight, hence its name, but a tripping device is activated just above the sediment-water interface to allow a measured free-fall.

Installing a PASSCAL broadband seismograph in Costa Rica. The seismometer is fixed to the base of a cement-lined hole beneath the large utility box left of center. During its three-year deployment, the instrument recorded earthquakes associated with the Central America subduction zone. Researchers visited the site at regular intervals to check the seismometer battery pack and to download earthquake data captured since the last visit. Image courtesy of Geoff Abers.

This animation describes how the Autonomous Underwater Vehicle (AUV) ABE is operated to map the seafloor. Sent along a predetermined survey pattern, the AUV uses multibeam sonar to collect data that is used to generate bathymetric maps.
