Picoplankton and nanophytoplankton concentrations as determined from flow cytometry analyses on water samples collected on Northern Gulf of Alaska LTER site seasonal cruises, 2019-2022.

This dataset the concentrations of pico-nanophytoplankton types present in water samples collected on Northern Gulf of Alaska LTER site seasonal cruises. Picoeukaryotes, nanophytoplankton, Synechococcus, and heterotropic bacteria were identified through flow cytometry and reported in concentrations of cells per milliliter. These data are part of the Northern Gulf of Alaska Long Term Ecological Research (NGA LTER) program. The LTER program is a National Science Foundation–funded network of 28 sites nationwide that focus on the influence of long-term and large-scale phenomenon on ecosystems. Additional funding for sampling is provided by the North Pacific Research Board (NPRB), the Alaska Ocean Observing System (AOOS), and the Exxon Valdez Oil Spill Trustee Council (EVOS) via the Gulf Watch Alaska program.

本数据集收录了阿拉斯加北湾长期生态研究（Northern Gulf of Alaska Long Term Ecological Research, NGA LTER）站点季节性航次采集的水样中，各类皮微纳级浮游植物（pico-nanophytoplankton）的浓度数据。研究通过流式细胞术（flow cytometry）鉴定出真核超微型浮游植物（picoeukaryotes）、微型浮游植物（nanophytoplankton）、聚球藻属（Synechococcus）以及异养细菌（heterotropic bacteria），并以细胞/毫升（cells per milliliter）为单位报告其浓度。
这些数据隶属于阿拉斯加北湾长期生态研究项目。长期生态研究（Long Term Ecological Research, LTER）计划是由美国国家科学基金会资助的全国性研究网络，在全美范围内设有28个站点，聚焦长期及大尺度现象对生态系统的影响。
本采样工作还获得了北太平洋研究委员会（North Pacific Research Board, NPRB）、阿拉斯加海洋观测系统（Alaska Ocean Observing System, AOOS）以及埃克森·瓦尔迪兹溢油赔偿委员会（Exxon Valdez Oil Spill Trustee Council, EVOS）通过阿拉斯加海湾观察计划提供的额外资助。
