This study deals with spatial and temporal distributions of organic and inorganic phosphorus in sedimentary columns from Al-Kabir Al-Shimaliand Al-Hussain estuaries, during the period March 2013- February 2014. Organic phosphorus concentrations ra nged between (2.0 - 207.6) μg/gin sediments from Al-Kabir Al-Shimali estuary, and from (1.7 –130.9) μg/gin sediments from Al-Hussainestuary. Sediment content from inorganic phosphorus ranged between (12.4 – 371.2)μg / g at sediments from Al-Kabir Al-Shimali estuary, and from (2.0 - 242.6)μg /g at Al-Hussain estuary. Granular composition of sediments did not play a significant role in the temporal and spatial distributions of organic and inorganic phosphorus. In general, organic and inorganic phosphorus concentrations decreased gradually from winter to summer, and from surface layers of the sedimentary column towards the deeper layers. The ratiobetween inorganic and organic phosphorus increasedfrom river into marine sediments. In addition, this ratio increased gradually as the sedimentdepthincreased, and was high in winter and low in summer.
Due to the lack informations on Biochemical of jellyfish in the Syrian waters, the aim of this paper is determining the nutritional value and organic content for each of the species Rhopilemanomadica, Pelagianoctiluca and Aequorea forskalea, and co mpared the biochemical composition of the three types , so the comparison showed clear differences in the content of organic material, the sugar were the most concentrated in the three species and lipid comes in second class, and then followed by the protein content and organic carbon.A.forskalea was the most containing sugar and R.nomadica the most lipids content, and P.noctiluca were the most protein content.R.nomadic was the highest content in organic carbon, R.nomadica and P.noctiluca were convergent contents of organic phosphorus, while the least contain of organic nitrogenwas in A.forskalea.
