每小时一次、全年一次的流式细胞术使人们有可能将季节环境变化与美国东北部大陆架上最小、最丰富的浮游植物的种群动态联系起来。为了评估这些数据是否延伸到离海岸更远的聚球藻，我们分析了在玛莎葡萄园岛海岸观测站(MVCO)和大陆架断裂之间航行的21艘邮轮上连续使用在航系统进行的流式细胞仪测量。我们描述了聚球藻的季节模式，已经在MVCO详细记录，如何在整个地区发生微妙的变化。我们发现，温度和分割率之间的潜在关系在整个大陆架上是一致的，并可以解释大部分观测到的浓度空间变异性。将单个细胞的属性与环境条件下的年度和区域模式联系起来，这些结果表明了自主监测的价值，并改善了在经济上重要的生态系统内微藻浮游植物动态的图景。
Hourly, year‐round flow cytometry has made it possible to relate seasonal environmental variability to the population dynamics of the smallest, most abundant phytoplankton on the Northeast US Shelf. To evaluate whether the insights from these data extend to Synechococcus farther from shore, we analyze flow cytometry measurements made continuously from the underway systems on 21 cruises traveling between the Martha's Vineyard Coastal Observatory (MVCO) and the continental shelf break. We describe how seasonal patterns in Synechococcus, which have been documented in detail at MVCO, occur across the region with subtle variation. We find that the underlying relationship between temperature and division rate is consistent across the shelf and can explain much of the observed spatial variability in concentration. Connecting individual cell properties to annual and regional patterns in environmental conditions, these results demonstrate the value of autonomous monitoring and create an improved picture of picophytoplankton dynamics within an economically important ecosystem.
