CSIRO, SRFME, Algal Biomass, Perth region, Southwest Australia, 2003-2005

Algal biomass in the Perth region were identified from quadrat surveys, as part of the SRFME research program. The aim of the SRFME Coastal project was 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, the project 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.

珀斯地区的藻类生物量通过样方调查（quadrat surveys）确定，该调查作为SRFME研究计划的一部分开展。SRFME海岸项目的目标是表征西澳大利亚州（Western Australia, WA）西南部的沿海底栖生态系统（benthic ecosystems），尤其聚焦于底栖礁生态系统的生产力、动态变化，以及在主要空间与时间尺度上驱动其变异的物理、化学与生物因素。为达成该研究目标，项目于2003年至2005年间，在南部纳多斯特角（Cape Naturaliste）与北部朱里恩湾（Jurien Bay）之间的一系列沿海站点开展每3个月一次的季节性采样。底栖采样工作与海表温度（Sea Surface Temperature, SST）卫星观测、海洋水色遥感以及其他水柱属性的水下测量相结合，同时配套沉积物生物地球化学采样。本区域内的底栖采样采用区域（100千米级）、局地（10千米级）与样点（1千米级）的嵌套尺度设计；同时在每个区域内增设采样站点，以纳入沿跨岸梯度的样点尺度变异。
