Samples were extracted from the ground surface with standard 120 mL polypropylene containers, and also at 20 cm below the surface using a sediment corer. Another set was taken in April 2012, from Platanias Port (Figure 2).
For the past three years, a team of engineers from the British Antarctic Survey and the National Oceanography Centre have pushed the boundaries of polar technology to design and build a titanium water-sampling probe and sediment corer capable of being lowered down the huge borehole in the ice made by a custom-built hot-water drill.
The group will bring with it a hot-water drill to penetrate the ice, water-sampling probe and sediment corer.
In the present study, a drop-weight sediment corer (diameter ~ 7.6 cm) was used in order to minimize sample disturbance and to examine sediment composition beneath the bed surface.
The sediment corer, made of a 48 cm long aluminium pipe with an inner diameter of 2.75 cm, took a core with a surface of 5.94 [cm.sup.2].
It was the first in a series of changes to the vessel to accommodate a 45-meter (150-foot) sediment corer, the longest of its kind in the U.S.
Chlorophyll concentrations were also determined from the water column samples collected with a Kemmerer bottle and sediment samples collected with a sediment corer (further methodological details are provided in Gradinger et al., 2009b).
Scientists can load up to 1,000 pounds of gear, including include sediment corers, temperature probes, water samplers, and biological sample pumps, in a basket mounted on the front of the submersible.
