Tunicates are marine filter-feeding invertebrates that can be found worldwide and which are the closest phylogenetic group to the vertebrates (Craniata). Of particular interest, colonial tunicates are the only known chorda...
COASTAL EUTROPHICATION AND HYPOXIA UNDER FOCUS: REDOX DEPENDENT BENTHIC NUTRIENT FLUXES ACROSS SEA BOUNDARIES IN THE NORTHEASTERN MEDITERRANEAN AND MARMARA SEA
Akçay, İsmail; Yücel, Mustafa; Department of Oceanography (2022-2-8)
Seafloor biogeochemistry can dramatically shift in response to deoxygenation and eutrophication-driven organic carbon production. In such conditions, biogeochemical cycling of key nutrients can be highly coupled to oxygen ...
