Linear regression between concentration (copies per g of wet weight) and storage time for the ndaF gene. Surface sediment samples were spiked with 100 ng (a) or 200 ng (b) of DNA or cell lysate (c). Samples were stored chilled (4 °C) in the dark and sampled at weekly to bi-weekly intervals and assessed using droplet digital PCR over a 24-week period.
