“…The organic matter in coastal marine sediments is a complex mixture of organic compounds originating from marine and terrestrial sources (Tesi et al, 2007). The preservation of organic matter in coastal marine sediments is an important link of the global carbon cycle and other bioactive elements as more than 90% of the organic carbon buried in the oceans occur in continental margin sediments (e.g.…”

“…Information on the sources of OC is crucial for understanding the global carbon cycle in the area of study, but differentiation of multiple sources of organic matter requires further studies using elemental, isotopic and molecular biomarkers such as C/N ratios and 13C, which have been used to identify the Relationship between OC and C : N ratio for this study, the Po estuary and prodelta [9,10], the Adriatic Sea [11] and western Adriatic [12,13], the particulate organic carbon (POC) from the Po River [14], the marine phytoplankton, zooplanckton and mucilaginous aggregates sampled in the North Adriatic Sea [15], and marine diatoms [16].…”

Abstract. In summer of 2007, short sediment cores (<20 cm) were collected in a littoral area of the North Adriatic Sea, Italy. Downcore measurements for radioactive tracers ( 234 Th, 7 Be) and organic matter signatures (OC, TN, C : N ratio) have been used to elucidate potential temporal changes in fluxes and cycles of organic matter in the area. Tracer distributions suggest that surface deposits throughout this area are rapidly reworked and this is supported by the findings of burrowing bivalves. Excess 234 Th was present at all stations, with surface activities (0-1 cm) ranging from 12 to 20 Bq/kg and inventories of 46 and 166 mBq cm −2 with penetration depths of about 10 cm. Steady-state particle mixing coefficients D b estimated using excess 234 Th ranged from ∼60 to 150 cm 2 yr −1 . The cores collected throughout the littoral system show a decrease in OC and TN down-core, and organic carbon signatures (OC and C : N) measured in sediment layers are indicative of multiple sources of sedimentary organic matter, where marine and estuarine phytoplankton is likely an additional important source of the direct input of organic matter.

“…Identifying vertical variability of plume is important in understanding the effect of euphotic depth towards primary productivity where primary productivity at estuary is highly associated with the river discharge [20]. Large river contribute to high input of discharge resulting in high concentration of biogeochemical contents in the plume.…”

Abstract. Large rivers transported high amount of discharge towards the sea and induced the river plume formation. The contents of the plume consist of suspended solids, nutrients, pollutants and other particles. Productivity at estuary depends on the organic and nutrient contents from the river discharge. Due to many possible factors, the dispersal of the plume shows spatial variation horizontally and vertically. The monsoonal wind is a factor that effecting plume vertical profile pattern. This study determines the vertical distribution pattern of the plumeat Pahang River through field observation. Several water parameters were measured during cruises conducted at respective monsoon. Data collected includes depth, chlorophyll-a, salinity, temperature and suspended particulate matter. Depth at Pahang's offshore usually does not reached more than 15 m depth because of the shallow continental shelf at South China Sea. The plume has higher concentration at the mouth of the river which causes the area to be less saline and it decreases as the station furthers from the river. Chlorophyll-a is distributed mainly at the surface level where the area is warmer and received freshwater runoff. Suspended particulate matter shows downward distribution from the front of the estuary towards deep water column depth (10 m). Temperature pattern shows warmer surface layer with depth less than 5 m while deeper water column has lower temperature. Vertical profile pattern of Pahang River plume generally shows slight difference between each monsoon by referring to particular parameter.
