  abstract = {{I}n the frame of the {COZOMED} project, concentrations of organic matter ({TOC}, {DOC}, {POC}) were monitored during two seasonal field campaigns (autumn, {O}ctober 2016 and spring, {A}pril 2017) in the {B}oughrara {L}agon, {T}unisia. {R}esults indicate strong influence of the seawater exchange and circulation, on the organic matter accumulation inside the lagoon, visible through a significant correlation between {TOC} and salinity in both seasons. {T}wo times higher concentration of {TOC} (up to 5.5 mg/l) was recorded in autumn, when high salinity water (46 ps mu) was present in the lagoon. {POC} made a relatively small percentage of {TOC} in autumn samples when high accumulation of {TOC}, especially its {DOC} fraction can be related to remineralization processes and zooplankton-mediated release of {DOC}. {I}ndeed, {PCA} analysis identified {DOC} as the most significant factor influencing the observed variability in autumn samples, and correlated to {NH}4+ thorn (p < 0.05) in surface waters, while {POC} was significantly (p < 0.05) correlated to chlorophyll a. {D}uring spring, organic matter in the lagoon was depth-dependent and under the high influence of salinity and temperature, and in the surface correlated to {NO}3-. {S}atellite data on lagoon water optical properties appear to support changes in measured organic matter concentrations indicating different optical properties of the water inside the lagoon during spring and autumn seasons. {T}he ocean color remote sensing, with properly validated and tested robust algorithms, accommodating optically shallow waters, can provide valuable tools for monitoring and timely detection of possibly detrimental changes inside the lagoon.},
