Description

Size of sinking aggregates of a Sargasso Sea Plankton community from roller tank experiments with seawater collected during R/V Atlantic Explorer cruises AE1718 and AE1808 in 2017 and 2018.

These data were published in Cruz and Neuer, 2019.

Methods & Sampling

Dataset acquisition description

Sargasso Seawater was incubated in 1.25 L roller tanks for 5 days in the dark at 3.5 RPM (for further details on roller tanks, see Shanks and Edmondson, 1989). Aggregation was tested with and without the addition of kaolinite clay. All treatments had n = 2 tanks. Aggregates formed were quantified, sized, and their sinking velocities and excess densities determined. TEP concentrations were determined as in Passow and Alldredge (1995). The stock of Alcian-Blue dye used for TEP quantification had a calibration factor (f-factor) of 84.15.

Aggregation was tested with and without the addition of kaolinite clay (control, 0.5 mg per L of kaolinite clay, 5.0 mg per L of kaolinite clay)
