كما أفاد تحليل صور الأقمار الصناعية من النوع SST في فهم و توصيف حركة الكتل المائية في الحوض الشرقي للمتوسط و أظهر خصائص كثيرة للعديد من الدوامات البحرية فإننا في هذا البحث نسلط الضوء على أهمية هذا النوع من الصور في الكشف عن ظاهرة الـ upwelling في الحوض الشرقي للمتوسط لما لها من انعكاسات بيولوجية هامة على البيئة البحرية. تم في هذا البحث الاعتماد على صور تعود لفترات مختلفة بهدف الإشارة إلى أماكن وجود الظاهرة و هذا سيكون بمثابة البوصلة التي ستشير إلى أماكن الاعتيان بغية دراسة المغذيات التي تعد أساس السلسلة الغذائية الأولى.
SST satellite images analysis has provided us a new description of the surface circulation in the eastern basin of the Mediterranean Sea. It showed many characteristics for a lot of mesoscale eddies. In this study, the SST analysis is focalised on the upwelling structure showing by images, in the eastern basin of the Mediterranean Sea, which has an important biological reflection at the marine environment. We have analyzed images for different periods to identifier this phenomena's places and this will be help us in situ nutrient observations.

The "Middle East" is one of the most tense regions of the world, and these tensions linked mainly to the existence of the Zionist entity as an outside intity cruel implanted in the heart of the region, and which seeks to exploit and steal any land a
nd wealth lies in his hands.
And with the discoveries of reserves the vast gas and oil in the levant basin escalated tensions in the region after Israeli efforts to exploit these reserves and stealing these resourses without taking and this led to the outbreak of differences bilateral and multilateral conflicts of interests among the countries in the region which allows Israel to play a key role in these issues, especially the Lebanese – Israeli conflict ,the Turkish – Cyprios case which Israel is third party in such conflicts.
This paper aimed to present the first record of Pterois miles (Bennet, 1828) off the
Syrian coast (Eastern Mediterranean). Two specimens (159; 206 mm SL) were captured in
Syrian waters between Lattakia and Jableh in 28th September 2015 and 10th Dec
ember
2015. This first record of common lionfish Pterois miles in the Syrian coast could confirm
the occurrence of this species in the Levant Basin (eastern Mediterranean). This is the fifth
record of the species reported to date in the region. These records are not sufficient to state
that the species is substantially established in the area, but investigations are rapidly
needed to avoid unfavorable consequences on local environment and economy.
In our research we studied and analyzed the different types of
methods used for automatic building detection from the satellite
images, then, we proposed a general methodology for building
detection based on its geometrical boundary features using Hough
transform for the rectangular forms.
The importance of this modern technology (remote sensing) follows from the fact that it allows estimating the wood stock by knowing the value of the NDVI index, which reduces the high cost and great effort needed by traditional forestry measurements.
The geometric correction of remote sensing images becomes a key issue in
production and updating digital maps, multisource data integration, management and
analysis for many geomatic applications. 2D polynomial functions are the most prevalent
to
achieve this correction.
Previous researches have shown that the application of 2D polynomials is
conditioned by the planarity of the terrain and the uniform distribution of ground control
points, but did not explicitly discuss the criteria for evaluating the success or failure of
their application. In this study, we will try to give some of these criteria and to develop
some old analog cartographic rules to suit the nature of the digital satellite images.
In this research, we discussed mathematical foundation for evaluating the precision
of control points- based geometric correction of satellite images. We have also tested the
effect of the topography of the imaged scene on this accuracy. The test has been carried out
by the use of satellite images extracted from Google Earth. These images cover some areas
in the city of Latakia in Syria. Also, control points have been extracted from Google Earth
and transformed into the Syrian stereographic coordinates system.
Results demonstrated that the second degree 2D polynomial is very suitable for plan
small scenes with uniform distribution of the control points over the entire scene.
