Comment:
Shell status: based on Rose Bengal coloring, divided between cytoplasm bearing and empty for PS931; divided between nonencrsuted and encrusted for NEWP-93 and EN199 based on visual determination
Sdt. dev. bulk weight: standard deviation of bulk weight is based on 10-15 repetitions of the measurements with the Sartorius SE2 ultra-micro balance (only measured for PS93.1 samples)
Further Details:
Sampling device: multiple closing plankton net (Hydro-Bios, Kiel) with an opening of 0.25 m² for PS93.1
Mesh size: 55 µm for PS93.1, 150 µm for NEWP-93 and EN199
Sieving size: 250 and 63 µm for PS93.1
Storage after retrieval: 4°C and stained with Rose Bengal/ethanol (96%) mixture for PS93.1,
2% formaldehyde seawater solution and buffered with sodium tetraborate (Borax) for NEWP-93, buffered formaldehyde to a 4% solution for EN199
Weighing: Sartorius SE2 ultra-micro balance (nominal resolution of 0.1 µg) for PS93.1, samples were weighted as bulk and each weighing was repeated at least ten times
Size measurements: KEYENCE VHX-6000 digital microscope for PS93.1
