Increasing  anthropogenic  pressure  on oneof the most  frequented  touristic coastal  region  of  Lebanon, Bay  of  Jounieh,  located  to  the  North  of  Beiruturgesthe assessment  of  itscoastal  marine  environmental  state.  Therefore, the geochemical, physical,  chemical  and  biochemical characteristics  of its sedimentsareanalyzed  andevaluated. The samples are collected from 3 three transects (North, Middle &amp; South) at 3  consecutive  depths  15,  30  and  60  m  using  the  platform  of  the  Lebanese  scientific vessel “CANA-CNRS”. The sediments of shallower sampling points,  15  and  30  m,  are mainly  composed  of  fine  sandand  are  poor  in  most  of  the  studied  parameters  except chlorophyll-a.While those of 60 m are exclusively represented by the fine fractionand contain maximumconcentrations  of  organic  matter (2.97%),  calcium  carbonates(47.7 %),  phosphates  (264  μg/g) and pheopigments(7.03  μg/g). The  labile  fraction through the  3  transects isrepresented  by  low  concentrations  of  carbohydrates  (0.011 -0.06 mg/g),  low  concentrations  of  proteins  (0.009 -0.051  mg/g)  and  highlevels  of  lipids (0.324 -1.036 mg/g).The results show thatthe deep points  (60 m) of Jounieh Bay are the  most  affected  by  the  anthropogenic pressure  combined  with  hydrodynamic  factors and geomorphological issues. Theenvironmental conditionof Jounieh’sBay appears to betolerantto the impact of multiformof contaminantsto which itis been exposed since longtime andit  isstill able  to show  a  meso-oligotrophic  systemwith  acceptable nutritive  values  for  the  proliferation  of  benthic  organisms.Thisstudy is  expected  to provide a valuable tool for monitoring and research programs in other marine areas of the Lebanese coast.
