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 both wet and dry deposition, the DIN/DIP molar ratio ranges between 63 and 349, exceeding by a factor of up to 22 the N/P ratio observed in seawater (ranging from 25 to 28) and (2) atmospheric deposition of DIP could reasonably account for a significant part of the new production (up to 38%) observed during the summer and autumn period (i.e., when water stratification is at its maximum).


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 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 Deposition of Macronutrients (Dissolved Inorganic Nitrogen and Phosphorous) onto the Black Sea and Implications on Marine Productivity*
Koçak, Mustafa; Tutsak, E.; Violaki, K.; Theodosi, C.; Zarmpas, P.; Kalegeri, P. (2016-04-01)
Two-sized aerosol samples were obtained from a rural site located close to Sinop on the south coastline of the Black Sea. In addition, bulk deposition samples were collected at Varna, located on the west coastline of the Black Sea. Both aerosol and deposition samples were analyzed for the main macronutrients, NO3-, NH4+, and PO43-. The mean aerosol nitrate and ammonium concentrations were 7.1 +/- 5.5 and 22.8 +/- 17.8 nmol m(-3), respectively. The mean aerosol phosphate concentration was 0.69 +/- 0.31 nmol ...
Organic nitrogen in rain and aerosol in the eastern Mediterranean atmosphere: An association with atmospheric dust
Mace, KA; Kubilay, N; Duce, RA (2003-05-31)
From March through early May of 2000, rain and bulk aerosol samples were collected at a coastal site on the eastern Mediterranean Sea at Erdemli, Turkey, and analyzed for nitrogen (N) species, including nitrate (NO3-), nitrite (NO2-), ammonium (NH4+), water-soluble organic N, urea, and dissolved free amino acids. Other ions were also analyzed, including Ca2+, Mg2+, K+, Na+, Cl-, and SO42-. Water-soluble organic N was found to contribute similar to17% and similar to26% of the total water-soluble N in rain an...

Daily aerosol and wet-only precipitation samples were collected, between January 1992 and January 1994 at a permanent station established on the Mediterranean coast of Turkey. Collected aerosol and rain samples were analyzed for major ions and a host of trace elements using a combination of analytical techniques, including ion chromatography, atomic absorbtion spectrometry and instrumental neutron activation analysis. The results have demonstrated;hat concentrations of parameters studied are higher than cor...
