Chlorophyll sampling in the coastal waters of south eastern Tasmania

Chlorophyll a concentration is widely used as a proxy to describe trends in phytoplankton biomass over spatial and temporal scales. The concentration of chlorophyll a in Storm Bay showed surprisingly little variation across the seasons. There was a gradient in concentration from site 1 to site 3, where chlorophyll a decreased slightly. It was highest and most variable at the inshore sites 1 and 9, and lowest at site 3, furthest out in the bay. There was no clear annually recurrent seasonal bloom, although data suggests higher values in spring and autumn (see later time series).

叶绿素a浓度被广泛用作表征浮游植物生物量时空变化趋势的替代指标。风暴湾内的叶绿素a浓度季节间变化幅度出人意料地小。站位1至站位3的叶绿素a浓度存在梯度分布，浓度随站位向湾外延伸略有降低。近岸站位1与9的叶绿素a浓度最高，且波动最为显著；位于海湾最外侧的站位3则浓度最低。尽管数据显示春季和秋季的叶绿素a浓度相对偏高（详见后续时间序列内容），但该海域并未出现明确的年度周期性季节性浮游植物水华。
