    • 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 ...

    • Sinking Organic Particles in the Ocean—Flux Estimates From in situ Optical Devices 

      Giering, Sarah LC; Cavan, Emma L; Basedow, Sünnje Linnéa; Briggs, Nathan; Burd, Adrian B; Darroch, Louise J; Guidi, Lionel; Irrison, Jean-Olivier; Iversen, Morten H; Kiko, Rainer; Lindsay, Dhugal J.; Marcolin, Catarina R; McDonell, Andrew MP; Möller, Klas O.; Passow, Uta; Thomalla, Sandy; Trull, Thomas W.; Waite, Anya M (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-18)
      Optical particle measurements are emerging as an important technique for understanding the ocean carbon cycle, including contributions to estimates of their downward flux, which sequesters carbon dioxide (CO<sub>2</sub>) in the deep sea. Optical instruments can be used from ships or installed on autonomous platforms, delivering much greater spatial and temporal coverage of particles in the mesopelagic ...
