Getting started with GO-BGC Data
Everything you need to begin working with the data
GO-BGC data can be used freely, with no restrictions. However, we ask that GO-BGC is properly acknowledged when used in a publication or a product.
Float data can be accessed in various formats through multiple data portals
BGC float data are automatically adjusted to deliver science quality data in near-real time. Data are adjusted following established protocols that are specific to each parameter. Documentation on how each parameter is adjusted can be found here. Below, you can find videos that summarize the adjustment process, as well as the quality of the resultant data.

Adjusting pH data (skip to 24:39)
Adjusting Nitrate data (skip to 19:52)

BGC Float Toolbox
Use this open-source toolbox to select, download, and visualize BGC float data from the Argo GDACs. Toolboxes are available in MATLAB, Python, and R. These toolboxes access the Synthetic profile (S-prof) files directly from the Argo GDAC, and detailed instructions on how to install and use them are included in the Github readme files. Tutorial videos can also be found below.
Some key functionalities:
- Download a specific float using its WMO ID number
- Select and download floats that are equipped with desired sensors
- Select and download profiles made within a specific geographic location and time
- Create a variety of plots, including trajectory of float(s), raw and QC’d profile data, and contour plots.
Download float 5904859. Plot float trajectory, and contour plot of only ‘good’ data.
