Biological, chemical and physical observations in inshore waters of the Great Barrier Reef (1979)

The distribution of salinity, temperature, suspended particles, light transmissivity, chlorophyll a and phaeophytin pigments, across the Great Barrier Reef lagoon offshore from Townsville, was measured from January 9, 1979 to January 3, 1980 at weekly intervals, weather permitting.The six stations sampled were located on a straight line between Cape Ferguson (19°16'S, 147°04'E), near AIMS, and Keeper Reef (18°45'S, 147°15'E).At every radar positioned station, six samples were taken from top to bottom at regular intervals of 2, 3, 3, 5, 6 and 8 m, at stations 1, 2, 3, 5, 7 and 9 respectively. This study was undertaken to investigate the extent of gradients in a number of parameters (salinity, temperature, suspended particles, light transmissivity, chlorophyll a and phaeophytin pigments) both across the lagoon and through the water column at different times of the year.

本数据集于1979年1月9日至1980年1月3日期间，在天气允许的条件下以周为采样间隔，对汤斯维尔近海大堡礁泻湖内的盐度、温度、悬浮颗粒物、透光率、叶绿素a以及脱镁叶绿素色素的分布情况进行了测定。
本次布设的6个采样站位，均位于弗格森角（19°16'S, 147°04'E，邻近澳大利亚海洋科学研究所（Australian Institute of Marine Science，简称AIMS））与守护者礁（18°45'S, 147°15'E）之间的直线上。
针对每个经雷达定位的采样站位，研究人员从表层至底层分层采集样品，其中站位1、2、3、5、7、9的采样间隔分别为2米、3米、3米、5米、6米与8米。
本研究旨在探究上述多项参数（盐度、温度、悬浮颗粒物、透光率、叶绿素a与脱镁叶绿素色素）在跨泻湖方向以及全年不同时段的水体垂直剖面中的梯度分布特征。
