Absorbance measurements of total particulate and non-algal particulate matter during Heincke cruise HE448 in Sognefjord and Trondheimsfjord, Norway, supplement to: Mascarenhas, Veloisa J; Voß, Daniela; Wollschläger, Jochen; Zielinski, Oliver (2017): Fjord light regime: Bio-optical variability, absorption budget, and hyperspectral light availability in Sognefjord and Trondheimsfjord, Norway. Journal of Geophysical Research-Oceans, 122(5), 3828-3847

Data presented are absorbance (Abs) measurements of total particulate (PA) and non-algal particulate (NAP) material. NAP Abs spectra were measured using the same filters upon bleaching with 90% sodium hypochlorite solution. Water samples were collected from near-surface (4m) and subsurface (close to observed deep chlorophyll maxima (DCM) depths. Near-surface samples were collected from Ferry-Box system (4HJena, Germany) and the DCM samples were collected from a SBE 911plus CTD system (SeaBird, USA). Water samples of varying volume (0.25 - 0.75 l), depending on water turbidity, were filtered onto 47 mm, pre-combusted, 0.7 μm glass fiber filters (Whatman, GF/F) under low vacuum. Absorbance was measured following the Quantitative Filter Technique (QFT) using a spectrophotometer with integrating sphere (Cary 4000, Agilent Technologies, USA). Reference spectra were measured using wet filters (ultra pure water). Blanks provided are average of spectra measured over a day. Samples were measured in triplicates.
