Glaucia Moreira Fragoso
About
My research field focuses on understanding the functional role, ecology, physiology and distributional patterns of phytoplankton communities in marine ecosystems. I am particularly interested in the use of technology for investigating the responses of phytoplankton communities to changes occurring in marine systems and the implications these have for food-webs, ecosystem functioning and biogeochemical cycles. The technology I use in plankton studies comprises a combination of ocean observational methods – from intercellular to planetary scales, such as flow cytometers, flow through microscopes, fluorometric sensors on autonomous platforms and buoys and hyperspectral satellites. My overarching interest is to understand the interlinks and tipping points between small and large temporal and spatial scales on plankton dynamics in marine environments and in aquaculture.
I have lately expanded my knowledge on primary producers and am working with macroalgae both in the wild and seaweed farms (MoniTARE project). In the MoniTARE project, which I am a PI of a prestigious Young Research Talent grant, I use affordable technology (mini-ROV) to predict macroalgal health state and biomass on seaweed farms. In addition, I am interested in investigating the ecological interactions between the timing of the phytoplankton spring bloom and fouling organisms (bryozoans) that are detrimental to the growth and market value of cultivated kelp. Over the last year, I have been involved as a collaborator of a Horizon European grant (DiverSea), where we use technological tools from a variety of methods (optical, imaging and acoustics, eDNA), platforms (satellites, AUVs, ROVs, USVs) and sampling approaches (in situ, discrete, remote sensing and citizen science) for deriving essential biodiversity variables.
I'm also part of the prestigious Outstanding Academic Fellow Program (Stjerneprogram 2022-2026) from NTNU and the PI of BOREALIS Aurora exchange program - enaBling knOwledge tRansfEr Among phytopLankton automated Imaging flow cytometer uSers.
