Autosub (2009)

Autosub (2009)

Autonomous underwater vehicle Autosub returning from its mission underneath the Pine Island Ice Shelf in the Amundsen Sea, Antarctica during expedition NBP0901. The Autosub measures water properties such as salinity, temperature, and oxygene content as well as the water depth below and the distance to the ice above it. It allows collecting data where ships cannot go.

Sediment grab (2007)

Sediment grab (2007)

Scientist use grab sampler like this one to collect sediment samples from the bottom of the ocean to studies its composition and propoerties. The sampler is lowered to the seafloor. When it hits the seafloor it closes the clamp and the material is brought back to the ship.

NB Palmer in the ice (2007)

NB Palmer in the ice (2007)

To study the sea ice in detail the NB Palmer is docking at the sea ice edge so scientists and instruments can easily be transferred onto the ice.

NB Palmer in McMurdo (2007)

NB Palmer in McMurdo (2007)

The NB Palmer is the main US research icebreaker operating around Antarctica and in the Southern Ocean. Here the vessel is at the pier of the US research station McMurdo, which can be seen in the background.

McMurdo Station (2007)

McMurdo Station (2007)

The research base McMurdo in the Ross Sea is the main US research station in Antarctica. During the southern summer season over 1000 people are working and living on the station, which also is the main logistic hub for much of the land based field work and for the supplies of the South Pole station. The US research icebreaker NB Palmer is docking at the pier of the station.

Weather station on Peter I. Island (2006)

Weather station on Peter I. Island (2006)

There are only few research stations on the large Antarctic continent. To complement the weather observations from the station and acquire data from a denser network autonomous weather stations (AWS) are setup all over the continent like this on Peter I. Island. The weather stations send their information via satellite back to research labs and weather services.

Sediment box corer (2006)

Sediment box corer (2006)

Large sediment box corer like this one on the German research vessel Polarstern are used, if scientist need a larger amount of sediment from the seafloor. They also allow to collect a sample with an intact surface and thus allow studying biology of the seafloor.

CTD rosette (2007)

CTD rosette (2007)

Detailed image of the CTD rosette on NB Palmer. The CTD is used to continuously record salinity (by measuring conductivity), temperature, and depth (by measuring pressure) as the instrument is lowered from the ship. Niskins bottles are also attached to the rosette so scientists can collect water samples.

Nicoya Peninsula sediment core field work (2010)

Nicoya Peninsula sediment core field work (2010)

VIMS students shown collecting bog and marsh samples on the Costa Rica Nicoya peninsula. The samples will be dated to help understand the palaeoseismicity of the region. In the image, a Russian peat corer is used to sample peat and other woody plant material. The coring chamber - the wide metal part visible near the water - is pushed into the subsurface. Extension rods, as shown here, can be used to push the corer deeper. When the target depth is reached, a T-handle is used to rotate the entire core assembly 180 degrees.
