Description

Particulate Organic Carbon and Nitrogen
from Ice and Water Samples

Data Note:
This data set consists of samples derived from a varity substrats, depths within substrats and sampling devices: ice, slush, brine, water, ice core, bottles, buckets etc. The user may want to out edit the file(s) before use.

Methods:
Weight percent carbon, hydrogen, and nitrogen were determined by combustion analysis at the UCSB Marine Science Institute Analytical Laboratory (www.msi.ucsb.edu/Analab/index.html), using automated organic elemental analyzers (CHNs) manufactured by Exeter Analytical (www.eai1.com) (formerly Control Equipment Corp.), Model 440XA. Instruments were operated following manufacturer-recommended settings and procedures, and calibrated using acetanilide, with performance being monitored to achieve an analytical precision of 0.3 wt. %. (per Wendy Kozlowski, e-mail 11/23/03)

POC and PON values have been corrected for a filtered sea water blank value of: 10.32 ug for POC and 1.59 ug for PON.

A short note on the "grid": The grid is a Cartesian plane covering the sample region in which distances are easy to calculate. The grid system used for SOGLOBEC is a universal transverse mercator (UTM) projection with a certain base point and rotation. The base point was chosen in the far south and the rotation was chosen to create one axis along the peninsula, and the other offshore. The units of UTM are meters, but the points are chosen in km rounded to the nearest km. Negative numbers mean that samples were taken southwest of the y axis or southeast of the x axis. For more details see: Complete explanation of the Southern Ocean grid system.

Instruments

bucket

Supplied Description:

Instrument Type

Generic Name: bucket

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0536/

Generic Description:

A bucket used to collect surface sea water samples.

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

Niskin bottle cast used to collect water samples for pigment, nutrient, plankton, etc. analysis

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.
