attribute NC_GLOBAL summary String In coastal environments with sandy seafloor, water is pushed through the surface layers of the permeable sediment by currents and wave orbital motion. The water penetrating the sands carries particles that may be slowed or trapped in the sediment matrix. The Phytoplankton in silicate sands column experiment investigated the transport and separation of phytoplankton algae through sand columns. Silicate sands of two grain sizes common in coastal and shelf environments were tested. Water with a natural phytoplankton community dominated by green algae (~5-10 µm diameter) and cyanobacteria (~2-5 µm) was pumped through the sands. Time series of phytoplankton cells released from the columns were analyzed using flow cytometry. The dataset presents the data produced by the flow cytometer.

Another experiment was conducted to find the cytometer results for carbonate sands of the same grain sizes that were treated with the same phytoplankton. See the Related Datasets section for this data.
