Suspended sediment, hydrodynamic, and biogeochemical observations in Fitzroy Estuary - Keppel Bay Region, QLD, 2022-2023; an eReefs sediment dynamics study

This dataset compiles all field observations collected as part of a sediment dynamics study in the Fitzroy Estuary - Keppel Bay Region from February 2022 to April 2023. Four voyages were undertaken during the 14-month study to deploy and maintain instrumentation at several fixed stations while also conducting spatial surveys and process measurements. \n\nThese in-situ observations primarily focus on hydrodynamics, sediment properties and physical-chemical properties, but also include other biogeochemical, bio-optical and meteorological data. Instrumentation, deployment timelines, locations and quality control details are summarized in the “ReadMe” file: Fitz_2022_23_Data_description.pdf, which also includes synoptic figures, tables and images. Additional information is provided in brief reports completed after each voyage, which summarize field activities along with pictures and preliminary visualization of raw data.\n\nTo accommodate a range of use cases, instrument data are duplicated into two data structures: “byInstrument” and “byLocation”. All timestamps are in local time (AEST), unless otherwise noted.\n\nThe project was a conducted as part of eReefs Phase 5 (https://research.csiro.au/ereefs/, https://www.ereefs.org.au/) combined with the CSIRO CERC project “Breaking new ground in coastal sediment dynamics: A measurement-to modelling pathway to support blue growth and coastal resilience”. \nRelevant links and outputs from this data collection will be periodically updated. \nLineage: Several types of instrument platforms were constructed and deployed for time-series measurements at fixed stations or for spatial surveys during the four voyages. A selection of these platforms is listed below, with additional details provided in summary documents. \n\nFixed stations \n1.\tBenthic landers at the ShipChannel and PortAlma sites \n2.\tPylon at the FitzPylonEreefs site \n3.\tLow-profile benthic lander for short (

本数据集汇编了2022年2月至2023年4月期间在菲茨罗伊河口-凯珀尔湾区域开展的沉积物动力学（sediment dynamics）研究中收集的所有野外观测（field observations）数据。在14个月的研究期间共进行了4次航次，旨在多个固定站点部署和维护仪器，同时开展空间调查（spatial surveys）与过程测量（process measurements）。

这些原位观测（in-situ observations）数据主要聚焦于水动力学（hydrodynamics）、沉积物特性（sediment properties）及理化特性（physical-chemical properties），同时也包含其他生物地球化学（biogeochemical）、生物光学（bio-optical）与气象数据。仪器设备、部署时间线、位置及质量控制细节汇总于“ReadMe”文件《Fitz_2022_23_Data_description.pdf》中，该文件还包含综合图表、表格及图像。每次航次结束后完成的简要报告提供了额外信息，其中汇总了野外活动、相关图片及原始数据的初步可视化结果。

为满足多种使用场景，仪器数据被复制为两种数据结构：“byInstrument”和“byLocation”。除非另有说明，所有时间戳均采用当地时间（AEST）。

本项目是eReefs第五阶段（https://research.csiro.au/ereefs/, https://www.ereefs.org.au/）的一部分，同时结合了CSIRO CERC项目“沿海沉积物动力学新突破：从观测到建模的路径以支持蓝色增长与海岸韧性”。本数据收集的相关链接及产出将定期更新。
数据谱系：在四次航次期间，构建并部署了多种类型的仪器平台（instrument platforms），用于固定站点的时间序列测量（time-series measurements）或空间调查。以下列出了部分此类平台，详细信息见汇总文档。
