SRFME: Jurien Bay Algal Biomass 2003-2005

Algal biomass in the Jurien Bay region were identified from quadrat surveys as part of the SRFME research program. The aim of the SRFME Coastal project is to characterize the coastal benthic ecosystems of southwestern WA, with particular focus on benthic reef cosystems, their productivity and dynamics, and the physical, chemical and biological factors driving variability along dominant spatial and temporal scales. To achieve this, we undertook 3-monthly seasonal sampling from 2003 - 2005 at a series of coastal sites situated between Cape Naturaliste in the south and Jurien Bay in the north. Benthic Sampling was integrated with satellite observations of SST, ocean colour and subsurface measurements of other water column properties, as well as sediment biogeochemical sampling. Within this region benthic sampling was nested at Regional (100s km) Local (10s km) and Site (1 km) scales and within each of the regions additional sites were sampled to incorporate site scale variability along cross-shore gradients.作为SRFME研究计划的一部分，研究人员通过样方调查识别了朱里恩湾（Jurien Bay）区域的藻类生物量。该SRFME海岸项目旨在表征西澳大利亚州西南部的沿岸底栖生态系统，重点聚焦底栖礁生态系统、其生产力与动态变化，以及在主导空间与时间尺度上驱动其变异的物理、化学与生物因子。为达成该研究目标，团队于2003年至2005年间，在南部纳奇斯特角（Cape Naturaliste）与北部朱里恩湾之间的一系列沿岸站点开展了每3个月一次的季节性采样。研究将底栖生物采样与海表温度（SST）卫星观测、海洋水色遥感、其他水柱属性的水下测量以及沉积物生物地球化学采样相结合开展。在该研究区域内，底栖采样按区域（100余千米尺度）、局地（10余千米尺度）与站点（1千米尺度）进行嵌套设计；且在每个区域内增设采样站点，以覆盖跨岸梯度下的站点尺度变异。
