Short summary
Short summary
We present a variability of absorption properties by different size fractions of particles suspended in the Spitsbergen Fjords waters in the summer season. The light absorption coefficient by all suspended particles, detritus and phytoplankton was determined for four size fractions: pico, ultra, nano and micro-particles. We have shown the proportions of particles from the size classes in the total absorptions, and we have found that dominant contribution had ultra-particles.

Short summary
Short summary
We aimed to improve the quality of regional Greenland Sea primary production estimates. Seventy two versions of primary production model setups were tested against field data. Best performing models had local biomass and light absorption profiles. Thus by using local parametrizations for these parameters we can improve Arctic primary production model performance. Annual Greenland Sea basin estimates are larger than previously reported.

Short summary
We present a variability of absorption properties by different size fractions of particles suspended in the Baltic Sea waters. The light absorption coefficient by all suspended particles (ap), detritus (ad) and phytoplankton (aph) was determined for four size fractions: pico-particles, ultra-particles, nano-particles and micro-particles. We have shown the proportions of particles from the size classes (micro-, nano-, ultra- and pico-particles) in the total ap, ad and aph.
