Skeletonema_marinoi_culture_1997 * Latitude: 55.000000 * Longitude: 2.000000 * Location: North Sea * Comment: Cultures of the diatom Skeletonema marinoi (formerly known as S. costatum; Sarno et al., 2005) / These experiments were performed using a diatom culture (from Alfred Wegener Institute for Polar and Marine Research) which was collected in 1997 in the North Sea.
Comment:
Average (Av.) measurements for Xanthan equivalent (µg Xequv) TEP content to dry weight (DW) ratio, solid hydrated density of the composite particles within the aggregates, POC content to DW ratio, POC content to PON content ratio, and carbon-specific respiration rate (C-spec. deg.) for the 15 and 4 °C treatment over the whole incubation period.
*Significant difference between the 15 and 4 °C treatment (Student's t test; p = 0.01).
