The influence of a flood plume associated with Cyclone Joy on larval fish assemblages in the central Great Barrier Reef

Between the 19th and 25th January 1991, ichthyoplankton were collected using a plankton net within and adjacent to the flood plume resulting from rainfall associated with Cyclone Joy.Sampling was conducted during daylight to enable location of the plume front. Three replicate tows were made on each of five occasions within three locations (on and parallel to the plume front, 3km within the plume and outside the plume front).Larval fish were removed from samples and identified to family level under a dissecting microscope.
Sampling was undertaken to investigate the influence on larval fish assemblages of a transient plume resulting from freshwater runoff associated with cyclonic rains.
Cyclone Joy crossed the Queensland coast on 26th December 1990 near Townsville, where it degenerated into a tropical depression.Sampling was conducted along the transect described in the metadata record "Zooplankton community structure and copepod egg production in coastal waters of the central Great Barrier Reef", which refers to data described in the papers:Thorrold SR and McKinnon AD (1992) Biological significance of the coastal boundary layer off Townsville, North Queensland. pp. 104-109.

1991年1月19日至25日期间，研究人员使用浮游生物网（plankton net），在与气旋“乔伊”（Cyclone Joy）相关降雨引发的洪水羽流（flood plume）内部及邻近海域采集鱼类浮游生物（ichthyoplankton）。本次采样于日间开展，以便准确定位羽流锋面（plume front）。研究人员在三个采样站位（羽流锋面之上且平行于锋面处、羽流内部3公里处以及羽流锋面外侧）的五个采样时段内，各完成三次重复拖网采样。从采集样品中分离出仔鱼样本，并在解剖显微镜下将其鉴定至科阶元。
本次采样旨在探究气旋性降雨引发的暂时性淡水径流所形成的洪水羽流，对仔鱼群落（larval fish assemblages）的影响。
气旋“乔伊”于1990年12月26日在汤斯维尔（Townsville）附近登陆昆士兰州（Queensland）海岸，随后减弱为热带低压（tropical depression）。
本次采样沿元数据记录（metadata record）《中大堡礁沿岸海域浮游动物群落结构与桡足类（copepod）产卵量》（Zooplankton community structure and copepod egg production in coastal waters of the central Great Barrier Reef）中描述的断面开展，该元数据对应的已发表文献包括：
