Huon Estuary Study - Spatial Survey Data 1996-1998

This dataset describes data collected from the Huon Estuary (Tasmania). Data was collected over a three day period approximately every three months from March 1996 until August 1998. 10 surveys were completed (HES1 to HES10). Data was collected from 61 sites, ranging from 0 salinity at Judbury to a salinity of 35 at the seaward end of the estuary near Huon Island. 5 sites were located near fish farms (refer to the separate metadata record for weekly data at these sites). At these sites, data was collected for all parameters (CTD, salinity, dissolved oxygen, nutrients, pigments, spectral absorbance and phytoplankton) measured. At a further 31 sites spread over the estuary, data was collected for the physical and chemical parameters only. At the remaining 25 sites, only physical (CTD) data was collected. Below Port Huon, samples were collected at three depths - surface, fluorescence maximum and from within the salt wedge. Above Port Huon, samples were collected from the surface and from the salt wedge (where present). This dataset forms part of the CSIRO Marine Research Huon Estuary study, conducted over the period 1996-1998.

本数据集记录了采集自塔斯马尼亚州（Tasmania）霍恩河口（Huon Estuary）的观测数据。数据采集周期为约每三个月一次，单次持续三天，采集时段从1996年3月起至1998年8月止，共计完成10次调查（编号依次为HES1至HES10）。本次采样覆盖61个位点，盐度跨度从贾德伯里（Judbury）区域的0盐度，延伸至河口向海端靠近霍恩岛（Huon Island）处的35盐度。其中5个位点邻近鱼类养殖场，相关站点的周度观测数据详见独立元数据记录。上述养殖场邻近位点采集了全部测量参数的数据，包括温盐深仪（CTD）、盐度、溶解氧、营养盐、色素、光谱吸光度以及浮游植物。另有31个分散于河口全域的位点，仅采集物理与化学参数数据；剩余25个位点仅采集物理（CTD）相关数据。在霍恩港（Port Huon）下游区域，采样分为表层、荧光峰值层以及盐楔内部三层；在霍恩港上游区域，采样仅采集表层与盐楔层（若存在）的数据。本数据集是1996-1998年间开展的澳大利亚联邦科学与工业研究组织（CSIRO）海洋研究霍恩河口专项研究的组成部分。
