The aim of this study was to understand spatial and temporal variations of inorganic and organic forms of phosphorus in the surface and deep waters of Erdemli shelf zone of the Mersin Bay. For this goal, timeseries hydrographical and phosphorus data were obtained monthly at the three selected stations between December 2001 and December 2003. The present results have shown that the concentrations of different fractions of total phosphorus displayed a decreasing trend from nearshore to shelfbreak zone of the bay. Total phosphorus (dissolved+particulate) in the shelf water was dominated by dissolved-P fraction (TDP:56-97%) and dissolved organic-P (DOP) was principally the major constituent of the TDP in the shelf water. Similarly, particulate organic-P (POP) dominates the particulate-P (PP) pool; however, the contribution of particulate inorganic-P (PIP) to PP pool was more pronounced in the nearshore zone fed by riverine inputs.

SPATIAL VARIATIONS OF PARTICULATE ORGANIC MATTER (POM) COMPOSITION AND CONCENTRATIONS IN SURFACE WATERS AND SEDIMENTS OF THE MERSIN BAY Akçay, İsmail; Tuğrul, Süleyman; Department of Oceanography (2015-9-8) Spatial and temporal variations of hydrophysical properties (temperature, salinity, density), eutrophication-related parameters (nutrients, Chl-a, dissolved oxygen) and particulate organic matter (POM) concentrations and composition (C/N/P) in water column and surface sediments were examined at 33 stations between April 2014 and February 2015 in Mersin Bay located at northeastern (NE) Mediterranean. Regional and seasonal distributions of nutrients in the Mersin Bay are affected by human-induced pressures. H...

Riverine nutrient inputs to the Mersin Bay, northeastern Mediterranean Akçay, İsmail (2018-10-21) In this study, biochemical (nutrients, total phosphorus (TP), biological oxygen demand) parameters were determined seasonally at downstream points of the five regional rivers (major/small ones: Ceyhan, Seyhan, Goksu, Berdan, Lamas) flowing into wide shelf zone of the northeastern (NE) Mediterranean. Long-term chemical data obtained seasonally in the 2008-2015 period were examined to assess seasonal variations in the chemical concentrations and annual mass influxes to the studied coastal sites, leading to be...
Spatial distribution and source identification of persistent organic pollutants in the sediments of the Yesilirmak River and coastal area in the Black Sea Dinc, Burak; ÇELEBİ, AHMET; Avaz, Gulsen; Canl, Oltan; Guzel, Baris; EREN, BEYTULLAH; Yetiş, Ülkü (2021-11-01) Surface sediments from the Yes,ilirmak River and the near coastal area in the Black Sea were collected using sediment traps to assess the spatial distributions of persistent organic pollutants and find their potential sources. Analyses were carried out to determine the concentrations of the persistent organic pollutants of seventeen polychlorinated dibenzo-p-dioxins and dibenzofurans, sixteen polycyclic aromatic hydrocarbons, seven polychlorinated biphenyls, and eight organochlorine pesticides using high-re...
Impacts of a buoyant strait outflow on the plankton production characteristics of an adjacent semi-enclosed basin: A case study of the Marmara Sea Oguz, Temel (2017-09-01) As documented by observational studies, the buoyant outflows emanating from straits and rivers with large amounts of nutrients and biogenic materials cause marked changes in the biochemical characteristics of the adjacent receiving water bodies. Here, using a three-dimensional biophysical model of the Marmara Sea-Bosphorus Strait two-layer exchange flow system and configuring it for the winter phytoplankton blooming period with limited top-down control, we show that complex buoyancy-induced basin-scale circ...
