title: Spectrophotometric measurements of absorption coefficients by phytoplankton during RV POLARSTERN cruise PS121 from 11 Aug to 10 Sep 2019

description: Water samples were taken during North Sea to Fram Strait expedition PS121 with RV Polarstern from 11 Aug to 10 Sep 2019. Water samples were collected from CTD Niskin bottles at five to six different depths from the upper 100 m and additionally from the ship's seawater supply pumped through teflon tubing from about 11m depth during underway as described in Liu et al (2018). All collected samples were filtered through 25 cm Whatman GF/F filters, respectively, under low-vacuum pressure (below 200 mbar). Blank filters were collected by soaking them in 0.2um filtered seawater. Measurements for particulate and non-algal (NAP) absorption were performed directly after filtration the quantitative filtration techniques-intergrative cavity measurement device and procedure from Röttgers et al. (2016) as described in Liu et al. (2018). Phytoplankton absorption (aph) was derived by subtracting the NAP (Bracher et al. 2021) from the particulate absorption.
description: Further specifications on the measurements:a) Instrument: light source: UV-VIS lamp (CF-1000- HC lamp, Illumination Technology, USA); absorption meter: Quantitative Filter Technique - Integrating Cavity Absorption Meter (QFT-ICAM) (Röttgers et al., 2016) with 80 mm- diameter integrating sphere; detector: photodiode array spectrometer (AVASPEC-ULS2048-RS-USB2, Avantes, the Netherlands).b) wavelength range of scan and resolution: 313.5-875.7 nm, 0.3 nm.c) slit band width: 2 nm.d) sample filters were bleached with 10% sodium hypochlorite (NaClO) solution for the OD measurement of NAP.e) samples were measured for four times and bleached samples were measured twice.f) dark current and blank filters were measured and subtracted.Further specifications about data analysis:a) interpolated wavelength range and resolution: 320-844 nm, 2nm.b) wavelength range for fluorescence correction: 670:800 nm.c) diameter of sample patch on GF/F filter: 2.133 cm.d) pathlength amplification factor (beta correction factor): 4.06 (Röttgers et al., 2016).e) no scattering correction for total particle absorption is applied; NAP absorption was adjusted with an offset in the range of 710-750 nm so that the median value of NAP absorption equals the median value of in total particle absorption in this spectral range. This adjustment is based on the assumption that phytoplankton pigments do not absorb in near-infrared (Neeley et al., 2018). This adjustment was not applied to NAP OD data.

title: Absorption coefficients by coloured dissolved organic matter from North Sea to Fram Strait measured underway with a Liquid Waveguide Capillary Cell system during POLARSTERN cruise PS99.1

description: Water samples were taken during North Sea to Fram Strait expedition PS99.1 with RV Polarstern from 14 to 23 Jun 2016. Water samples were collected from the ship's seawater supply pumped through teflon tubing from about 11m depth during underway as described in Liu et al (2018). The same water samples were measured as in Liu et al. (2021). Water samples for CDOM absorption analysis were filtered through 0.2 µm filters and analysed onboard with a 2.5-m path length liquid waveguide capillary cell system (LWCC, WPI) following Levering et al. (2017). Details on method adaptation to our instrumentation set-up are provided in Alvarez et al. (2022). Salinity data were extracted from https://doi.pangaea.de/10.1594/PANGAEA.873156.

title: Liocarcinus holsatus in the Sylt Rømø bight in 2022

description: Due to changing temperature regimes in the North- and the Wadden Sea, a fish survey in the Sylt Rømø bight (SRB) was established in 2007 for at least ten years. The aim is to investigate the Wadden Sea fish fauna with special interest in changes of migration behavior, species composition and feeding habits. Since 2021 an assessment of the epibenthic species in the net hauls was included. Seven stations are sampled monthly inside the SRB. Two additional stations, one outside the bight, one close to the Danish border are sampled as references four times a year. For sampling a mini bottom trawl, total length 17 m, trawl opening 7 m, height 3 m with a mesh size of 36 mm in the wings, 16 mm in the mid part and 6 mm in the cod end is used. At every station one haul in the water column and another at the bottom are sampled, for 15 minutes at a speed of approximately 2 knots. The data will help to give a more detailed picture of food chains and energy flows inside the Wadden Sea.
