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.
As you can see on our Results pages we already analyzed a lot of data from the Mauritanian, the Peruvianand the Benguela upwelling area analyzed. Now we are again taking a look at datafrom the upwelling area off Mauretanian and Senegal andand the Cape Verde Islands region obtained in 2019. Below on this pageyou can see where exactly the data came from. Each point marks a UVP profile.
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.
