PACKAGE DESCRIPTION: This dataset includes chemical, discrete sample, physical and profile data collected from G.O. SARS in the North Greenland Sea and Norwegian Sea from 2013-07-17 to 2013-07-30. These data include DELTA CARBON-13, DELTA CARBON-14, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, SALINITY, TOTAL ALKALINITY (TA), WATER TEMPERATURE, phosphate and silicate. The instruments used to collect these data include CTD and bottle. These data were collected by Siv K. Lauvset of Bjerknes Centre for Climate Research as part of the CLIVAR_75N_2013 dataset. CDIAC associated the following cruise ID(s) with this dataset: CLIVAR_75N_2013 The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.

VARIABLES / PARAMETERS:

Dissolved Inorganic Carbon
Abbreviation: DIC
Observation type: discrete
In-situ / Manipulation / Response variable: In-situ observation
Measured or calculated: Calculated
Replicate information: Duplicates: o On the 75oN transect two niskin bottles were closed at the same depth (or within 10 m of each other) and we used these as duplicates. The depth was varied from station to station. o On the 74.5oN transect we only had 12 niskin bottles so instead of closing two at the same depth we drew two samples from one niskin. The depth was varied from station to station. These duplicates therefore also give information on whether our sampling method (different samplers etc) affects the carbon values. o There is no duplicate on stations 335 and 341 o Using all duplicates we have a mean precision of 1.3±1.0 μmol kg-1 for DIC.
Total alkalinity
Abbreviation: TA
Observation type: discrete
In-situ / Manipulation / Response variable: In-situ observation
Measured or calculated: Measured
Curve fitting method: titrating the samples with HCl, using a VINDT A A T instrument from Marianda, and used a Gram fit to get the alkalinity (Figure 10). The system generally worked very well for the entire cruise, but there are some software issues.
Uncertainty: CRMs were run before and after each position using the same sequencing as for DIC. The accuracy on the CRM values was approximately +20 μmol kg-1.
