Surface Water - Aquatic Organism Tissue Sample Results

Description

This data set provides results of tissue from organisms found in surface waters, from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN). The data are of tissue from individual organisms and of composite samples where tissue samples from multiple organisms are combined and then analyzed. Both the individual samples and the composite sample results may be given so for individual samples, there will be a row for the individual sample and a row for the composite where the number per composite is one. The data set contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result. Due to file size limitations, the data has been split into individual resources by year. The entire dataset can also be downloaded in bulk using the zip files on this page (in csv format or parquet format), and developers can also use the API associated with each year's dataset to access the data. Users who want to manually download more specific subsets of the data can also use the **[CEDEN Query Tool](https://ceden.org/find_data_page.shtml)**, which provides access to the same data presented here, but allows for interactive data filtering.

57 This resource contains all tissue data available from the CEDEN database, in the [Apache Parquet file format]((https://parquet.apache.org/)). The data is partitioned by year. Parquet is a free and open source data storage format that allows for fast and efficient processing of large datasets. It is compatible with a variety of data analysis platforms, including the R and Python programming languages, through the [Apache Arrow platform](https://arrow.apache.org/). An example showing how to use this data with the R programming language is available [here](https://gist.github.com/daltare/209acf0789b4f1bdec272c323ba45315). https://data.ca.gov/dataset/38cb5cca-1500-42e7-b359-e8e3c5d1e087/resource/dea5e450-4196-4a8a-afbb-e5eb89119516/download/tissuedata_parquet_2024-05-08.zip
