| We estimated pelagic primary production (PP) in the coastal (< 200 m depth) Mediterranean Sea from satellite-borne data, its contribution to basin-scale carbon fixation, its variability and long-term trends during the period 2002–2016. Annual coastal PP was estimated at 0.041 Gt C, which approximately represents 12 % of total carbon fixation in the Mediterranean Sea. About 50 % of this production occurs in the eastern basin, whereas the western and Adriatic shelves contribute with 25 % each of total coastal production. Strong regional variability is revealed, from high-production areas (> 300 g C m−2) associated with major river discharges, to less productive provinces (< 50 g C m−2) located in the southeastern Mediterranean. PP variability in the... |

| In situ laser diffractometry (LD) is increasingly used in oceanographic studies to estimate sediment transport, particle fluxes and to assess the concentration of marine phytoplankton. It enables an accurate characterization of the size distribution of suspended particles from the scattering signal produced by their interaction with a collimated laser beam. LD reliably reflects the sizes of suspensions dominated by nearly spherical particles; however, when complex particle morphologies dominate the suspension (e.g. phytoplankton) the resulting particle size distribution (PSD) may present significant variations attributed to different factors. In particular, the orientation of non-spherical particles - which abound in the sea – modifies LD measurements of... |
