From: Sólveig Rósa Ólafsdóttir Date: Thu, Feb 6, 2020 at 10:15 AM Subject: Data submission from Iceland To: Alex Kozyr Cc: Alice Benoit-Cattin , Magnús Danielsen Dear Alex Please find three data files attached. They are for the Irminger Sea (FX9) time series 2014-2019 and the Iceland Sea (LN6) time series 2014-2019. Also from our new station on Stokksnes (St5) section 2012-2019. This station is in the Iceland Basin, although it is on the northern limit and the depth is only 1150 m. The correct citation for this dataset is: Solveig R. Olafsdottir, Alice Benoit-Cattin and Magnus Danielsen, 2020. Alkalinity, dissolved inorganic carbon, temperature, salinity, nutrients and dissolved oxygen collected from discrete samples and profile observations using CTD and bottle from ARNI FRIDRIKSSON and BJARNI SAEMUNDSSON in the North Atlantic Ocean from 23-05-2012 to 06-11-2019. The whole datasets have been checked for errors and doubtful values. The data were corrected, deleted or left unchanged as judged appropriate. Therefore we have not attributed quality flags for the data but with the stringent analytical protocols used, we believe the data should have the quality flag 1. The only exception is the TA data where the method is new in our lab and we see improvement in precision and accuracy with time. Here we think that the flag 2 is more appropriate. We have changed our methodology and do now measure TA instead of pCO2. A short updated summary of the methods and quality issues that we suggest should be listed with the metadata is also attached that comes in addition to the paper from 2010: The Irminger Sea and the Iceland Sea time series measurements of sea water carbon and nutrient chemistry 1983–2008.
