Diatom communities from seawater samples of the G-NEO1 coastal monitoring station in Nuevo Gulf, Argentina.

This dataset includes 80 observations encompassing diatom counts from seawater samples and associated water temperature from the G-NEO1 (Golfo Nuevo Estación Oceanográfica) coastal monitoring station in Nuevo Gulf, Puerto Madryn city (Argentina). Diatom data comprises monthly surface and bottom samples collected over distinct time periods. Surface samples were taken from 1 meter below the surface during high tide, spanning September 2021 to October 2023. Bottom samples, collected 1 meter above the seabed during high tide, cover the period from March 2022 to October 2023. The main purpose of this station is to evaluate seasonal and inter-annual variations of oceanographic variables (e.g. temperature, salinity, nutrients, chlorophyll and carbonate system) and the dynamics of the plankton community. GNEO-1 has been sampled monthly by members of the Laboratorio de Oceanografía Biológica (LOBio) of the Centro para el Estudio de Sistemas Marinos - Consejo Nacional de Investigaciones Científicas y Técnicas (CESIMAR - CONICET) since 2018. GNEO-1 is part of the Red Argentina de Observación Marina (ROMA) within the Network of the Pampa Azul Initiative (https://pampazul.gob.ar/redes-de-observacion/), the GOA-ON Network (https://www.goa-on.org/) and the NF-POGO NANO-DOAP Global Project (https://nf-pogo-alumni.org/projects/global/). The dataset has been formatted following the standards of the Tropical South American Diatom Database (https://zenodo.org/records/5721364)--a database constituent of Neotoma (www.neotomadb.org), a global community-curated database by regional experts for multiple types of paleoecological data--and as part of the project "DiatomS mEEt Databases: resources and practices to enable large-scale ecological research (SEED)" funded by the International Society for Diatom Research (https://isdr.org/early-career-networking-award/).本数据集包含80组观测数据，涵盖阿根廷马德林港新海湾G-NEO1（Golfo Nuevo Estación Oceanográfica，新海湾海洋观测站）沿海监测站点的海水样本硅藻计数数据与配套水温数据。硅藻数据包含不同时间段采集的月度表层与底层样本：表层样本采集于高潮时水面下1米处，时间跨度为2021年9月至2023年10月；底层样本采集于高潮时距海床1米处，时间范围为2022年3月至2023年10月。该站点的核心目标为评估海洋学变量（如温度、盐度、营养盐、叶绿素与碳酸盐体系）的季节与年际变化，以及浮游生物群落动态。自2018年起，阿根廷海洋系统研究中心（CESIMAR）与阿根廷国家科学与技术研究委员会（CONICET）下属的生物海洋学实验室（Laboratorio de Oceanografía Biológica, LOBio）成员，每月对G-NEO1站点开展采样工作。G-NEO1是阿根廷海洋观测网（Red Argentina de Observación Marina, ROMA）的组成部分，该观测网隶属于潘帕斯蓝倡议（https://pampazul.gob.ar/redes-de-observacion/）、GOA-ON网络（https://www.goa-on.org/）以及NF-POGO NANO-DOAP全球项目（https://nf-pogo-alumni.org/projects/global/）。本数据集遵循南美热带硅藻数据库（https://zenodo.org/records/5721364）的标准进行格式化，该数据库是由区域专家审核维护的全球古生态数据共建数据库Neotoma（www.neotomadb.org）的组成部分；同时本数据集也是由国际硅藻研究学会（International Society for Diatom Research, ISDR）资助的“硅藻邂逅数据库：支撑大规模生态研究的资源与实践（SEED）”项目的一部分，该项目资助链接为https://isdr.org/early-career-networking-award/
