Measurements of atmospheric and oceanographic variables (wind speed and direction, relative humidity, dew point, atmospheric pressure and temperature, sea temperature, pressure and salinity) were collected from the Kalloni Bay mooring (26.2084, 39.1677) in Lesvos Island.

The data refer to fifteen-day and monthly measurements of sinking particulate matter in the marine areas of the northern Aegean, Cretan, Ionian Seas and the Levantine/northeastern Mediterranean. The collection instruments were PPS3/3 Technicap sediment traps with collection areas of 0.125 m² and 12 receiving cups. The locations and corresponding depths of the trap deployments for the different areas are as follows: Historical biogeochemical flux data for the time period 2015: A) Northern Aegean Sea (station M2, Athos Basin): 39°58.16′ N, 24°43.48′ E; d...
