Scientific Data Usage

Effective date: 05 August 2015 Dataset

Individuals or organisations conducting research where data from the project may be useful can apply for access by emailing

The dataset is currently not quality controlled and so comes ‘as is’.

For sailors we have a policy that data is freely available via the website map, while for academics  / researchers we ask for a donation as the project is run from volunteer time and efforts i.e., there is no under-pinning grant funding salaries etc. Currently, we suggest £150 GBP per year of data, or part thereof, requested. However, as we do not want to hinder research we only ask for a ‘donation’ – the decision is yours.

We also expect that the project is acknowledged in any resulting publication using the following:

The authors thank the Secchi Disk project for the seafarer Secchi Depth data.

Welcome to PlayingWithData, this is the home of projects that aim to engage the community in the collection and analysis of environmental information.

The first project is, a joint global scientific project supported by Pixalytics Ltd that aims to engage seafarers in studying marine phytoplankton.

You can participate in this project by making a Secchi disk (a 30 cm flat white disk attached to a tape measure or rope, see the project website for more details) and using the free to download ‘Secchi’ application to record measurements; the App is available from the  or .

Once installed you’ll be asked to provide your boat’s name so data uploaded to the database can be verified. Once uploaded, the data should appear on the map below within 48 hours. Over time we’ll develop a more interactive site so the data can be viewed in different ways.

The long term aim is to understand more about the phytoplankton (microscopic plant-like cells) that underpin the marine food chain.

To zoom in double click on the map, and to pan drag with the mouse. To see the boat name and Secchi depth click on a pointer (please be aware that uploaded data may take up to 48 hours to appear).

If you are having problems uploading your data then you need to update your App to the latest version. Also, if the data doesn’t appear on the map below then you need to accept Cookies and refresh the display.
