A total of 74 aerosol and 23 rain samples were collected at a rural site located on the coast of the Eastern Mediterranean, Erdemli, Turkey (3 33ʹ 4ʺ N and 34 1 ʹ 18ʺ E). Concentrations of NO3-, NH4+ and water-soluble total nitrogen (WSTN) were respectively determined by Ion Chromatography and High Temperature Combustion Method. The arithmetic mean aerosol WSON was 23.8 ± 1 .3 nmol N m-3 whilst the volume weighted mean (VWM) concentration of WSON in rain was 21. μmol N L-1. WSON in aerosol was mainly influenced by coarse particles (66 %). Rain and air mass history were found to influence the daily variability of aerosol WSON. Effect of sporadic dust events on WSON concentrations was statistically 1.3 times larger compared to non-dust events. Correspondingly, dissolved inorganic nitrogen and agricultural activities explained 42 % and 43 % of the aerosol WSON. The atmospheric water-soluble nitrogen flux would sustain one-third and three-quarter of the new production in the coastal and offshore waters of the Cilician Basin.

Atmospheric water-soluble organic nitrogen (WSON) in the eastern Mediterranean: origin and ramifications regarding marine productivity
Nehir, Munevver; Koçak, Mustafa (2018-03-13)
Aerosol and rain sampling in two size fractions was carried out at a rural site located on the coast of the eastern Mediterranean, Erdemli, Turkey (36 degrees 33'54 '' N, 34 degrees 15'18 '' E). A total of 674 aerosol samples in two size fractions (337 coarse, 337 fine) and 23 rain samples were collected between March 2014 and April 2015. Samples were analyzed for NO3-, NH4+ and ancillary water-soluble ions using ion chromatography and water-soluble total nitrogen (WSTN) by applying a high-temperature combu...
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 ...
CHEMICAL CHARACTERIZATION AND SPECIATION OF THE MACRO NUTRIENTS IN THE ATMOSPHERIC PARTICLES, DRY AND WET DEPOSITION MODES OVER THE EASTERN MEDITERRENEAN: SOURCE AREAS, BIO-AVAILABILITY AND IMPACT OF ATMOSPHERIC INPUTS ON MARINE PRODUCTIVITY
Nehir, Münevver; Koçak , Mustafa; Department of Oceanography (2016-10-10)
Two stage aerosol (coarse: PM10-2.5 and fine: PM2.5) and rainwater samples were collected at a rural site (Erdemli) located on the coast of the eastern Mediterranean, between January 2014 and April 2015. Concentrations of the water-soluble nitrogen species (organic nitrogen (WSON), nitrate, ammonium, total nitrogen (WSTN) and urea) were measured in a total of 740 aerosol and 23 rainwater samples. Among the nitrogen species, WSON (24.6 ± 16.3 nmol N m-3) denoted the highest arithmetic mean and followed by am...
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...
Chemical characteristics of atmospheric aerosols in a rural site of northwestern Anatolia
Yenisoy-Karakas, S; Tuncel, Süleyman Gürdal (1997-09-01)
Aerosol samples were collected daily at a rural mountainous site of northwestern Anatolia during September 1993-April 1994. Concentrations of SO42-, NO3-, Cl-, NH4+, Na+, K+, Ca2+ and Mg2+ have been determined. Sulfate made up the 30% analyzed aerosol mass with a 2.14 mu gm(-3) average concentration. Measured concentrations were comparable with other rural area data except Ca2+ which was higher in our station with an average concentration of 1.12 mu gm(-3). Monthly concentrations of major ions fluctuate dep...
