Marine Benthic Biomass Data

This dataset contains Puget Sound benthic biomass data by major taxonomic group. <b>Before accessing data please download the <a href="https://data.kingcounty.gov/api/views/h6jg-f45t/files/4339b4e4-e2fa-4b9a-93e5-7c5f33c36849?download=true&filename=README_Benthos.pdf">README</a> file. </b>

King County monitors the community of animals that live in and on the sediments at the bottom of Puget Sound. These animals, called benthos, are crucial to the health of Puget Sound. We collect sediment samples to help us understand what the sediments are like physically and chemically and how they support different species.

Benthic samples have been collected since 2015 from <a href="https://kingcounty.gov/en/dept/dnrp/nature-recreation/environment-ecology-conservation/science-services/puget-sound-marine-monitoring/sediments-topic-page/subtidal-benthos">14 sites</a>. Every 2 years we sample eight sites in Elliott Bay and every 5 years we collect samples from three deep sites in the mainstem of the Central Basin and three smaller embayments. We also collect benthic samples near treatment plant outfalls as well as cleanup sites.

Benthic samples are typically collected in replicates (3-5 samples per location and period of time). These replicates help us understand the variability of the benthic community at that location and are distinguished by the fields "Sample Rep ID" and "Field Replicate".

本数据集收录了普吉特湾底栖生物量数据，按主要分类群进行划分。在访问数据之前，请下载<a href="https://data.kingcounty.gov/api/views/h6jg-f45t/files/4339b4e4-e2fa-4b9a-93e5-7c5f33c36849?download=true&filename=README_Benthos.pdf">README</a>文件。<b>金县对生活在普吉特湾底部沉积物中及其上的动物群落进行监测。这些被称为底栖生物的动物对于普吉特湾的健康至关重要。我们收集沉积物样本以帮助我们了解沉积物的物理和化学特性，以及它们如何支持不同的物种。</b>自2015年以来，我们从<a href="https://kingcounty.gov/en/dept/dnrp/nature-recreation/environment-ecology-conservation/science-services/puget-sound-marine-monitoring/sediments-topic-page/subtidal-benthos">14个地点</a>收集了底栖样本。每隔两年，我们对埃利奥特湾的八个地点进行采样，每隔五年，我们从中央盆地主航道及三个较小的湾口收集样本。我们还从处理厂排放口附近以及清理现场收集底栖样本。<b>底栖样本通常以重复样本的形式收集（每个地点和时间段收集3-5个样本）。这些重复样本有助于我们了解该地点底栖群落的变化性，并通过“样本重复ID”和“野外重复”字段进行区分。</b>有关相应的底栖生物鉴定和丰度数据，请参阅<a href="https://data.kingcounty.gov/Environment-Waste-Management/Marine-Benthic-Abundance-Data/er5r-bf3q">海洋底栖丰度数据</a>。如有关于数据的问题，请联系<a href="mailto:[e-mail]">[e-mail]</a>。
