Description
| This dataset consists of four Imaging FlowCytobot (IFCB) datasets, comprised of images of nano- and micro-plankton triggered by particle scatter. Two datasets represent time-series observations from D. acuminata blooms in Salt Pond, Eastham, Massachusetts, collected in the summers of 2015 and 2021 from subsurface waters at an observatory platform at the pond’s center. These two datasets are a subset of all the IFCB image data collected during this time period and only represent the samples that were annotated and analyzed in the associated manuscript. The other two datasets come from a culture experiment in 2024 in which Mesodinium prey availability was manipulated across two treatments (prey-saturated and prey-limited) and tracked for 12 days. The .hdr files contain sample metadata, including field names for the .adc file. The .adc file contains flow cytometric data from each image, including particle scatter parameters. The .roi file contains all the images associated with that sample. |

Data Source
| In both 2015 and 2021, an IFCB was deployed from a floating platform over the deepest point of Salt Pond. Particles, including D. acuminata, were detected via>680 nm fluorescence triggered by a 635 nm laser. In 2015, the IFCB was maintained at ~5 m depth except on July 2–3, when it was profiled between 1–5 m in1 m increments. In 2021, depth was alternated between 2 and 3 m using a programmable winch. Sampling occurred every 24 min, with brief interruptions for cleaning and maintenance. Two D. acuminata (DAMV01) cultures were established with different Mesodinium (JAMR) prey ratios: prey-saturated (3:1JAMR:DAMV01) and prey-limited (1:3 DAMV01:JAMR). IFCB samples were collected every 2 h during an initial dark period, then hourly during subsequent light–dark cycles. A caged magnetic stirrer mixed cultures for 3 min before each ~2 mL sample. Sampling alternated between the two cultures via separate intake lines. |
