1. Data Use Guidance

By viewing or downloading data from ERDDAP, data users acknowledge and agree to the following:

  1. Data users should contact the project PI to gain context and to ensure that their intended use of the data is appropriate, as well as to identify personnel to acknowledge in produced documents (e.g., publications). PI contact information can be found in the tagged fish metadata table or contact Arnold Ammann ().

  2. Data may be updated as new information, such as fish detections and deployment details, is received and processed. Any problems with a dataset should be reported to the project PI. Furthermore, data users cannot hold ERDDAP or project PIs responsible for any inaccuracies. As a rule of thumb, data collected within the last 3 years can be subject to revision.

  3. ERDDAP provides data collection and validation tools to data contributors, but it cannot guarantee the quality or completeness of data.

  4. Data can be downloaded from ERDDAP and used for publication, however the raw data cannot be published on another website. Please contact the PI for discussion on data sharing.


2. Which dataset do I want?


3. Download preliminary real-time data

Real-time data can be downloaded via ERDDAP website. Data is preliminary and subject to revision: https://oceanview.pfeg.noaa.gov/erddap/tabledap/FEDcalFishTrack.html

Alternatively, data can be imported directly into R. To do so, please use the following R code here.


4. Download processed real-time and autonomous detection data

You can find processed real-time and autonomous JSATS detection data for 2012-2023 on ERDDAP at this url: https://oceanview.pfeg.noaa.gov/erddap/tabledap/FED_JSATS_detects.html

You can access metadata on all receiver deployments here.

You can access metadata on all tagged fish here.

Download all data (summarized as hourly detection events) for a single water year: 2012 2013 2014
2015 2016 2017 2018 2019 2020 2021 2022 2023

Alternatively, data can be imported directly into R. To do so, please use the following R code here.

Please note that although these data have been filtered to remove the vast majority of false detections, these data may contain rare instances of a false detection. Manual inspection of fish movement plots is strongly recommended before analyzing data.

Data processing and filtering details can be found here.

This data delivery project is still under development but it is usable now.


If you intend to download data off the ERDDAP website, rather than importing the data directly into R, please follow these instructions:

The dataset title is: JSATS California Fish Tracking. There are many available fields so click on the question mark bubble for an explanation of each field.

A simple data request to get you started would be:

  1. Click on the above link

  2. Uncheck all variables at the top of webpage.

  3. In the “time (Receiver Detection Time, UTC)” field, you need to adjust the start and stop date. By default it limits the start and stop time to today’s date. To expand the time range pull the left side of the slider bar all the way to the left. Or you can type in the date range if you know it already.

  4. Then check only these fields: fish_id, time, study_id, (Go over to the far pulldown box and select only one study_id) receiver general location, receiver_location (Receiver Location (GPS name)), receiver_river_km (Receiver River Kilometer, km)

  5. In “Server side functions” - in the pull down select “Order by”, then in the box to the right select “fish_id”, then in next box to right select “time”.

  6. File type: pick a file type, try *.csv, which can be opened directly with Notepad, Notepad++, or imported into Excel.

This should get you a table of detections (filtered from raw data) that is sorted by FishID and detection time for one Study.
