An ice corer is used to drill into deep ice and remove long cylinders of ice from which information about the past and present can be inferred. Polar ice cores contain a record of the past atmosphere - temperature, precipitation, gas content, chemical composition, and other properties. This can reveal a broad spectrum of information on past environmental, and particularly climatic, changes. They can also be used to study bacteria and chlorophyll production in the waters from which the ice core was extracted.
Brine samples were collected from auger holes that were drilled into sea ice using a 2 inch kovacs coring auger. Brine that flowed into the bottom of the hole was collected using a tygon tubing attached to a 60 cc syringe.
Polypropylene/titanium trace metal coring system used to collect sea ice samples.
A small subset of sea ice samples from designated "ice stations" (Stations 31, 33, 39, 42, 43, 46) were collected by drilling ice with a polypropylene/titanium trace metal coring system.
A cordless electrical drill was used with various types of corers (including US Snow, Ice and Permafrost Research Establishment [SIPRE] corer manufactured by Jon's Machine Shop, Fox, Alaska) to sample permafrost below the tunnel floor.
