Abstract	Human activities related to the sea have had significant impacts on all ecosystems and are evident from coastlines and coastal areas to the depths of the oceans. The Marine Strategy Framework Directive (MSFD) establishes a common approach among the European Union member states for the prevention, protection, and preservation of the marine environment from damages caused by human activities, while also allowing for the use of the marine environment without disrupting the ecosystem itself. Macrofauna is one of the indicators used by the MSFD to assess the good environmental status of marine ecosystems. On the other hand, meiofauna is not currently considered in monitoring programs although it possesses numerous characteristics that make it potentially more effective than macrofauna. For this project meiofauna samples were collected from thr deep sea of the Aegean sea and from the open-sea stations network of the Greek MSFD, aiming to evaluate whether these organisms could serve as a suitable tool for assessing the environmental status of deep-sea ecosystems in the eastern Mediterranean. Our results indicate a dominance of nematodes, particularly the genera Sabatieria and Syringolaimus. Chlorophyll a and CPE values suggest an oligotrophic ecosystem, (especially in the southern Aegean region) with reduced food quantity that decreases with depth. Finally, the ecological status assessment using meiofauna as a tool indicates that the sampled areas fall into the category of good ecological status. This study suggests that meiofauna, particularly nematodes, is a useful tool for assessing the ecological status and could be used as a complementary approach to macrofauna for monitoring the marine environment under the Marine Strategy Framework Directive. However, further work and research are required to understand which specific meiofauna characteristics are most suitable for this purpose.
