Ocean carbon from space: Current status and priorities for the next decade Brewin, Robert J.W.; et. al. (2023-05-01) The ocean plays a central role in modulating the Earth's carbon cycle. Monitoring how the ocean carbon cycle is changing is fundamental to managing climate change. Satellite remote sensing is currently our best tool for vi...
Comparison of Diffusive and Total Nutrient Fluxes from the Sediment of Mersin Bay, Northeastern Mediterranean Sea Akçay, İsmail (2023-04-01) In this study, sediment diffusive and total nutrient fluxes were calculated for the Mersin Bay, Northeastern (NE) Mediterranean Sea. Positive fluxes of nutrients from the sediments indicated that sediment acts as a source ...
Distinct patterns of sedimentary phosphorus fractionation and mobilization in the seafloor of the Black Sea, Marmara Sea and Mediterranean Sea Akçay, İsmail; Yücel, Mustafa (2023-03-10) Phosphorus (P) is a key element to all life that is used for structural and functional component of all organisms. The cycling of sedimentary P may differ depending on the redox-conditions of the overlying waters affecting...

We also found this species in o...
Phylogeographic and Morphological Analysis of Botrylloides niger Herdman, 1886 from the Northeastern Mediterranean Sea Temiz, Berivan; Öztürk, Esra; Blanchoud, Simon; Karahan, Arzu (2023-03-01)
Differences in food web structure and composition between new and nearby older lakes in West Greenland suggest succession trajectories driven by glacier retreat Jeppesen, Erik; Davidson, Thomas A.; Meerhoff, Mariana; De Meester, Luc; Gonzalez-Bergonzoni, Ivan; Vidal, Nicolas; Arndt, Hartmut; Juergens, Klaus; Sommaruga, Ruben; Özkan, Korhan; Lauridsen, Torben L.; Tserenpil, Sh (2023-03-01) With the retreat of glaciers, new ponds and lakes are often formed. These are gradually colonised and become more productive as vegetation develops in their catchments, creating more complex food webs. Near the Jakobshavn ...
Estimation of nutrient fluxes from the flooding of the Wadi Gaza catchment into the Mediterranean Sea Al-Najjar, Hassan; Purnama, Anton; Özkan, Korhan (2023-03-01) The coastal catchment of Wadi Gaza is the main surface water basin that flows down to Gaza coastal plain zone and drains into the Mediterranean Sea. The modeling-based assessment of the hydrological system is an essential ...
Fisheries impact on the Sea of Marmara ecosystem structure and functioning during the last three decades SAYGU, İSMET; Akoğlu, Ekin; Gül, Güzin; Bedikoğlu, Dalida; DEMİREL EROL, Nazlı (2023-1-13) The Sea of Marmara (SoM), without doubt, is one of the most disturbed marine ecosystems of the Mediterranean basin. As a semi-enclosed and a recognized eutrophic basin, it has a unique natural characteristic by permanent s...
Annual reproductive cycle of a successful Lessepsian immigrant in the Eastern Mediterranean Sea, Pomadasys stridens (Forsskål, 1775) (Family: Haemulidae) Eşkinat, Deniz; Gücü, Ali Cemal; Ok, Meltem (2023-01-01) The striped piggy, Pomadasys stridens (Forsskål, 1775), is one of the successfully colonized Lessepsian immigrants entering the Mediterranean through the Suez Canal. This study was carried out to understand to what extent ...
Uncovering ecological regime shifts in the Sea of Marmara and reconsidering management strategies DEMİREL EROL, Nazlı; Akoğlu, Ekin; Ulman, Aylin; Ertor-Akyazi, Pınar; Gül, Güzin; Bedikoğlu, Dalida; YILDIZ, Taner; Yilmaz, I. Noyan (2023-01-01) Ecosystem regime shifts can alter ecosystem services, affect human well-being, and trigger policy conflicts due to economic losses and reductions in societal and environmental benefits. Intensive anthropogenic activities m...
