FNQ_2021_V01 Voyage dataset: Feb - March 2021; Biogeochemical and hydrodynamic observations along the river-reef continuum of estuaries in eastern Cape York, Australia

Archive of biogeochemical and hydrodynamic data from 2021 research voyage in eastern Cape York.\nData were collected via several observational methods including an underway, flow-though sampling system, underway CTD casts, benthic lander deployments, >25hr station keeping, water column profiling, across-axis hydrodynamic transects and along-axis profiling transects. A detailed description of data, methods, and activities is included in this archive as a voyage sampling report.\nLineage: Data were collected during a research voyage, which covered approximately 1200km in 14 days, including both continuous and discrete sampling while underway, at anchor stations and in specific habitats, e.g. mangroves and seagrass. Continuous measurements of surface water quality were collected by pumping water to a series of flow cells onboard the research vessel throughout the voyage. These continuous data require calibration based on discrete samples and include periodic but minor data gaps due to equipment maintenance. Underway CTD profiles of the vertical water column were simultaneously conducted across ~210km of the voyage track. \n\nSampling at anchor stations were conducted over full tidal cycles (>25 hrs) in three estuaries (Daintree, Normanby, Escape), with shorter anchor intervals and benthic lander deployments in four other systems (Bizant, Kennedy, Olive, and Jackey Jackey). These sampling activities included a suite of hydrodynamic and biogeochemical observations, which are grouped by specific topics and sampling methods and are described in detail in the voyage sampling summary (included).

2021年约克角东部科考航次生物地球化学与水动力数据档案。
本次数据通过多种观测手段采集，包括走航式流通采样系统、走航CTD（Conductivity Temperature Depth，温盐深剖面仪）剖面测量、底栖着陆器布放、超过25小时的定点驻留、水体剖面探测、跨轴水动力断面测量以及沿轴剖面探测。本档案附带航次采样报告，其中详细记述了数据、观测方法及科考活动的具体细节。
数据溯源：本次数据采集于总航程约1200公里、历时14天的科考航次，涵盖走航过程中、锚定站位及特定生境（如红树林与海草床）的连续与离散采样。全航次期间，科考船通过泵取海水至船载系列流通池，持续采集表层水质数据。此类连续数据需基于离散样本开展校准，且因设备维护存在周期性小幅数据缺失。航迹约210公里范围内同步开展了垂直水体的走航CTD剖面测量。
锚定站位采样在三个河口（丹特里河、诺曼比河、埃斯凯普河）开展，覆盖完整潮汐周期（超过25小时）；另外四个采样区域（比赞特、肯尼迪、奥利弗以及杰克·杰克伊）则采用更短的锚定间隔，并开展了底栖着陆器布放作业。本次采样活动包含一系列水动力与生物地球化学观测，按特定主题与采样方法进行分类，详细说明见所附航次采样总结报告。
