This dataset contains in situ water column data at offshore monitoring stations using a Conductivity Temperature Depth (CTD) sensor for the Whidbey Basin. A CTD is a multi-sensor array that measures dissolved oxygen, salinity, temperature, density (calculated), nitrate + nitrite, and fluorescence (as a measure of chlorophyll).

This dataset contains water quality samples collected from Puget Sound, lakes, and streams in the region which can be filtered by "Site Type" and "Area".

To see where water quality samples are collected, see the WLRD Water Quality Collection Sites dataset.

This dataset contains phytoplankton samples collected from Puget Sound and analyzed using a particle imaging analyzer (FlowCAM®). For more information see the King County marine phytoplankton webpage.

This specific dataset summarizes phytoplankton abundance and biovolume data by functional group. Additional datasets summarize abundance and biovolume data by:

• Size Class (all size classes in a sample in one line)

• Sample By Size Class (each sample size class in one line)

• Sample by Generic Functional Group

• Sample by Taxonomic Group

For locator information, see the WLRD Water Quality Collection Sites dataset.

For corresponding water quality data matched by Grab ID see the Water Quality dataset.

This dataset contains chemistry results from marine sediment sample collected from offshore (subtidal) and beaches (intertidal) from Puget Sound. It can be filtered by "Site Type".

This dataset contains Puget Sound benthic biomass data by major taxonomic group. Before accessing data please download the README file.

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 14 sites. 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".

For corresponding benthos identification and abundance data see: Marine Benthic Abundance Data.
