Methods:
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. Cholorophyll-a concentrations were determined using the techniques as reported in previous submissions of ice core and water column data. Multiple sample numbers reflect replicate samples taken from the same hole.

Instruments

Ice Corer

Supplied Name: IceCoring

Supplied Description:

Instrument Type

Generic Name: Ice Corer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/56/

Generic Description:

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.
