浅卡罗琳海山位于热带西太平洋。它的最高点在地表以下57米，并穿透透光层。因此，它是研究海山对浮游生物分布影响的理想场所。在这里，2017年8月和9月，通过流式细胞术（FCM）对卡罗琳海山的浮游病毒丰度和分布进行了研究。病毒样颗粒（VLP）的总丰度范围为0.64 × 106-18.77 × 106个颗粒/ml，平均值为5.37 ± 3.75 × 106个颗粒/ml。鉴定了具有相似侧向散射但不同绿色荧光强度的三至四个不同的病毒亚群。在深叶绿素最大值（DCM）之上，区分了两个中等荧光病毒（MFV）亚群。在DCM和更深的层之间，只有一个MFV子簇被解析。一般而言，低荧光病毒（LFV）包含最丰富的亚群。然而，在75-150米水柱中，MFV丰度高于LFV丰度。高荧光病毒（HFV）在整个水柱中构成了最不丰富的亚群。在海山站，浮游病毒丰度显著增加。环境因素，包括水温和硝酸盐浓度是最相关的病毒浮游生物丰度的变化在海山站。浅海山和当地洋流之间的相互作用可以支持大量的病毒现存量，对浮游病毒造成所谓的间接“海山效应”。
The shallow Caroline Seamount is located in the tropical western Pacific Ocean. Its summit is 57 m below the surface and penetrates the euphotic zone. Therefore, it is ideal for the study of the influence of seamount on plankton distribution. Here, virioplankton abundance and distribution were investigated by flow cytometry (FCM) in the Caroline Seamount in August and September 2017. The total abundance of virus‐like particles (VLP) was in the range of 0.64 × 106–18.77 × 106 particles/ml and the average was 5.37 ± 3.75 × 106 particles/ml. Three to four distinct viral subclusters with similar side scatter but different green fluorescence intensities were identified. Above the deep chlorophyll maximum (DCM), two medium fluorescence virus (MFV) subclusters were discriminated. Between the DCM and the deeper layers, only one MFV subcluster was resolved. In general, low fluorescence viruses (LFV) comprised the most abundant subclusters. In the 75–150 m water column, however, the MFV abundance was higher than the LFV abundance. High fluorescence viruses (HFV) constituted the least abundant subcluster throughout the entire water column. Virioplankton abundance was significantly enhanced at the seamount stations. Environmental factors including water temperature and nitrate concentration were the most correlated with the variation in virioplankton abundance at the seamount stations. Interactions between shallow seamounts and local currents can support large virus standing stocks, causing a so‐called indirect “seamount effect” on the virioplankton.
