Abstract:

This dataset contains experimental data on the effect of artificial marine snow on marine benthic invertebrates, water quality measurements, water nutrient measurements, oxygen measurements, and data on oil biodegradation (n-alkanes).

Purpose:

To investigate the effects of artificial marine snow on benthic invertebrates.

Data Parameters and Units:

Treatment code, spot #, aquarium #, replicate #, Survival of invertebrates (#), survival of foraminifera (#), salinity (‰), pH (-), temperature (degrees C), dissolved oxygen saturation (%), dissolved O2 (%), dissolved oxygen saturation (%), hopane-normalized peak areas (-), time (day), statistical analyses

Methods:

Oil loading to each treatment with oil: 0.63 g oil per 625 cm2 surface area of sediment in aquaria, equivalent to 10 g/m2. Marine snow ‘loading’ to each treatment with snow: equivalent to approx. 625 cm3. Clay loading: 3.15 g kaolin clay per 625 cm2, equivalent to 50.4 g/m2. Control treatment was only a 5 cm thick natural sediment layer. Alginate powder (alginic acid sodium salt) was mixed with filtered natural sea water, phytoplankton biomass, and kaolin clay. Then mixed with CaCl2 solution to precipitate the artificial marine snow flocks.
