Atmospheric Input of Inorganic Macro-Nutrients in the EasternMediterranean: Ramifications Regarding Marine Productivity



Atmospheric nutrient inputs to the northern levantine basin from a long-term observation: sources and comparison with riverine inputs
Koçak, Mustafa; TUĞRUL, SÜLEYMAN; Mihalopoulos, N (2010-01-01)
Aerosol and rainwater samples have been collected at a rural site located on the coastline of the Eastern Mediterranean, Erdemli, Turkey between January 1999 and December 2007. Riverine sampling was carried out at five Rivers (Ceyhan, Seyhan, Goksu, Berdan and Lamas) draining into the Northeastern Levantine Basin (NLB) between March 2002 and July 2007. Samples have been analyzed for macronutrients of phosphate, silicate, nitrate and ammonium (PO43-, Sidiss, NO3- and NH4+). Phosphate and silicate in aerosol ...
Atmospheric trace element and major ion concentrations over the eastern Mediterranean Sea: Identification of anthropogenic source regions
GÜLLÜ, GÜLEN; DOĞAN, GÜRAY; Tuncel, Süleyman Gürdal (2005-11-01)
Concentrations of elements and ions measured in aerosol samples collected from March 1992 to the end of December 1993 were investigated to identify source regions affecting chemical composition of aerosols in the eastern Mediterranean atmosphere. Collected samples were analyzed for approximately 40 elements and ions using a combination of atomic absorption spectrometry, instrumental neutron activation analysis, ion chromatography and colorimetry. Statistical techniques, such as enrichment factors and a non-...
Atmospheric trace element concentrations over the eastern Mediterranean Sea: Factors affecting temporal variability
GÜLLÜ, GÜLEN; Olmez, I; Aygun, S; Tuncel, Süleyman Gürdal (1998-09-20)
Concentrations of elements and ions were measured in aerosol samples collected between March 1992 and December 1993 at a rural station on the Mediterranean coast of Turkey. Concentrations of pollution-derived elements are lower than corresponding concentrations reported for the western Mediterranean region, due to the longer distances traveled by the particles to reach the eastern Mediterranean region. Concentrations of elements vary on timescales ranging from days to seasons. Short-term variations in the c...
Atmospheric deposition of inorganic phosphorus in the Levantine Basin, eastern Mediterranean: Spatial and temporal variability and its role in seawater productivity
Markaki, Z; Oikonomou, K; Koçak, Mustafa; Kouvarakis, G; Chaniotaki, A; Kubilay, N; Mihalopoulos, N (2003-07-01)
Total and dissolved inorganic phosphorus (IP) was measured in both rainwater and aerosol samples collected from two remote coastal areas: on the island of Crete (Greece) and at Erdemli (Turkey). Particle size distributions of P, as well as total deposition were also measured. Wet and dry deposition of dissolved inorganic phosphorus (DIP) from Crete are compared with simultaneously obtained dissolved inorganic nitrogen (DIN) and with productivity data from the literature. Our results indicate that (1) in bot...
Atmospheric global dust cycle and iron inputs to the ocean
Mahowald, NM; Baker, AR; Bergametti, G; Brooks, N; Duce, RA; Jickells, TD; Kubilay, N; Prospero, JM; Tegen, I (American Geophysical Union (AGU), 2005-12-30)
Since iron is an important micronutrient, deposition of iron in mineral aerosols can impact the carbon cycle and atmospheric CO2. This paper reviews our current understanding of the global dust cycle and identifies future research needs. The global distribution of desert dust is estimated from a combination of observations of dust from in situ concentration, optical depth, and deposition data; observations from satellite; and global atmospheric models. The anthropogenically influenced portion of atmospheric...
