• In-air one-point calibration of oxygen optodes in underway systems 

      Becker, Meike; Olsen, Are; Reverdin, Gilles (Journal article; Peer reviewed, 2021)
      Ships of opportunity are a frequently used platform in surface ocean carbon observations and estimating the annual ocean carbon sink. For understanding the drivers behind changes in the ocean carbon system, oxygen measurements ...
    • An international intercomparison of stable carbon isotope composition measurements of dissolved inorganic carbon in seawater 

      Cheng, Lin; Normandeau, Claire; Bowden, Roxane; Doucett, Richard; Gallagher, Barbora; Gillikin, David P; Kumamoto, Yuichiro; McKay, Jennifer L; Middlestead, Paul; Ninnemann, Ulysses S; Nothaft, Daniel; Dubinina, Elena O.; Quay, Paul; Reverdin, Gilles; Shirai, Kotaro; Mørkved, Pål Tore; Theiling, Bethany; Geldern, Robert; Wallace, D. W. R. (Peer reviewed; Journal article, 2019)
      We report results of an intercomparison of stable carbon isotope ratio measurements in seawater dissolved inorganic carbon (δ 13C‐DIC) which involved 16 participating laboratories from various parts of the world. The ...
    • North Atlantic ocean circulation and decadal sea level change during the Altimetry era 

      Chafik, Leon Martin; Nilsen, Jan Even Øie; Dangendorf, Sönke; Reverdin, Gilles; Frederikse, Thomas (Peer reviewed; Journal article, 2019-01-31)
      Regional sea-level rise is characterized by decadal acceleration and deceleration periods that typically stem from oceanic climate variability. Here, we investigate decadal sea-level trends during the altimetry era and pin ...
    • Trends of Ocean Acidification and pCO2 in the Northern North Sea, 2003-2015 

      Omar, Abdirahman; Thomas, Helmuth; Olsen, Are; Becker, Meike; Skjelvan, Ingunn; Reverdin, Gilles (Peer reviewed; Journal article, 2019-10-29)
      For continental shelf regions, the long‐term trend in sea surface carbon dioxide (CO2) partial pressure (pCO2) and rates of ocean acidification are not accurately known. Here, we investigate the decadal trend of observed ...
    • Wintertime fCO2 variability in the subpolar North Atlantic since 2004 

      Fröb, Friederike; Olsen, Are; Becker, Meike; Chafik, Leon Martin; Johannessen, Truls; Reverdin, Gilles; Omar, Abdirahman (Peer reviewed; Journal article, 2019)
      Winter data of surface ocean temperature (SST), salinity (SSS) and CO2 fugacity (fCO2) collected on the VOS M/V Nuka Arctica in the subpolar North Atlantic between 2004 and 2017 are used to establish trends, drivers, and ...
