We discuss the benefits to operational PFT products by using for diatoms and prokaryotic phytoplankton in synergy S5POC PFT products in order to improve the data quality of these two PFT within the

marine environment (warming, acidification, nutrient and light availability), fewer microalgae (phytoplankton) grow, reducing the ocean’s biological productivity. Contact Judith Hauck +49(471)4831-1848 E-Mail

since 2020 there are operational global and regional CMEMS PFT CHL products, covering the whole phytoplankton community, TROPOMI PFT products are gap filling because of lower uncertainties, even in coastal [...] fill the gaps for assessing the spectral underwater radiation and four dimensional tracking of phytoplankton groups in the global ocean.

trace elements is essential to a healthy diet. That’s true not only for humans, but also for phytoplankton. As a key carbon dioxide sink, these tiny algae in the Southern Ocean can have significant effects [...] Wegener Institute (AWI) and the University of Bremen reveals an interesting connection: When phytoplankton simultaneously have access to more iron and more manganese, their biotic communities change. As

Plankton Lab Our research focusses on marine phytoplankton with an emphasis on diatoms. We isolate these species-rich unicellular organisms from the sea and rivers right on our doorstep and have species
