    • Deep ocean particle flux in the Northeast Atlantic over the past 30 years: carbon sequestration is controlled by ecosystem structure in the upper ocean 

      Lampitt, Richard S.; Briggs, Nathan; Cael, B. B.; Espinola, Benoit; Hélaouët, Pierre; Henson, Stephanie A.; Norrbin, Maria Fredrika; Pebody, Corinne A.; Smeed, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-16)
      The time series of downward particle flux at 3000 m at the Porcupine Abyssal Plain Sustained Observatory (PAP-SO) in the Northeast Atlantic is presented for the period 1989 to 2018. This flux can be considered to be sequestered for more than 100 years. Measured levels of organic carbon sequestration (average 1.88 gm<sup>−2</sup> y<sup>−1</sup> ) are higher on average at this location than at ...

    • Energy budget diagnosis of changing climate feedback 

      Cael, B. B.; Bloch-Johnson, Jonah; Ceppi, Paulo; Fredriksen, Hege-Beate; Goodwin, Philip; Gregory, Jonathan M.; Smith, Christopher J.; Williams, Richard G. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-21)
      The climate feedback determines how Earth’s climate responds to anthropogenic forcing. It is thought to have been more negative in recent decades due to a sea surface temperature “pattern effect,” whereby warming is concentrated in the western tropical Pacific, where nonlocal radiative feedbacks are very negative. This phenomenon has however primarily been studied within climate models. We diagnose ...
