Spatial distribution of biooptical and thermohaline characteristics in NW part of Southern Adriatic pit
Biogeochemical processes in the Adriatic Sea are highly influenced by circulation patterns and water mass dynamics. In order to investigate specific winter circulation and distribution of phytoplankton, an oceanographic cruise was conducted from February 28th till March 3rd 2015 in the southern Adriatic. Two major transects were investigated: (i) Dubrovnik to 1000 m isobath (in direction 210º), and (ii) 1000 m isobath to Lastovo island. The surveyed area is greatly influenced by the Levantine Intermediate Water (LIW) and East Adriatic Current (EAC). The warm and saline LIW represents a part of the EAC and enters the Adriatic from the Ionian Sea spreading northwards at the intermediate layer, usually at depths between 100 and 600 m, with the core from 200 to 400 m. Total of 45 CTD casts were performed and concurrent measurements of temperature, salinity and bio- optical parameters ; bio-optical measurements of chlorophyll fluorescence (Chl F), optical particulate backscattering and beam attenuation were collected. The surveyed area demonstrated circulation dependent high patchiness in distribution of Chl F. The significant Chl F signal was detected up to 450 m depth, indicating either active primary production in deep layers or recent subduction of the surface water. The core of the LIW was not as pronounced as in previous years. However, higher salinity and temperature values, together with dissolved oxygen minimum were observed around 450 m.
