At the moment, we are especially interested in rhizaria, single-celled zooplankton, which are often able to conduct photosynthesis. Many Rhizaria are very fragile and difficult to investigate, but especially these fragile groups can make up a substantial part of the zooplankton biomass in the ocean. In the upwelling area off California, 81% of the zooplankton is made up by Rhizaria! We want to have a look at further upwelling areas, in order to identify the distribution of Rhizaria in those regions and to understand their possible role in the carbon transport to the deep sea.
Our new dataset was recorded during RV Meteor cruise M148 and covers a transect from Brazil to Africa. During this transect, full depth profiles to almost 5000 m depth were conducted. Furthermore, a lot of images were collected at the African coast. In the map on the left you can see the current research area, as well as the completed regions. Each dot represents one profile. Below, you can find out where exactly the transect profiles where recorded and you can have a look at the progress of our current project.
We need 10 identifications for each image in order to properly evaluate the assignment of this plankton organism. From the 16 images that you evaluate, 8 are randomly picked and shown together with 8 further test images. This means that we need around 11000 identification rounds to complete this project. If everybody sorts 1000 images, we are quickly done within a few weeks.
We developed the sorting mode in order to be able to show you an even greater variety of images and to get a prediction from you, which category these images could belong to. While you could only confirm the prediction of our neural network in the puzzle mode, you can choose from many different categories in the sorting mode.
We are now working on a dataset from RV Meteor cruise M136 from Peru, where we were able to collect 99 UVP profiles.
You can also help us by playing our sorting mode. We show you a set of images from three main categories which you can place in a fitting category.
In order to create an account you have to log in to the puzzle mode. When you have sorted 1000 images there, you unlock a link to the sorting mode so that you can play both modes.
