20.500.12556/DiRROS-20041 Signatures of pigments and processes in the south Adriatic Pit - project MEDUZA During two cruises of the MEDUZA experiment conducted in July 2003 and May 2005 various data were obtained over the deepest part of the southern Adriatic Pit. Temperature, salinity, light transmission and fluorescence were measured in July 2003. During May 2005, except CTD measure- ments the samples were taken for laboratory determination of phytoplankton pigments with HPLC technique. During both cruises irradiance and radiance were measured at 14 wavelengths in the range 340-715 nm with optical probe to about 100 m depth. Bad weather conditions during both cruises caused interruption of measurements that continued after 24 to 48 hours. Stormy conditions have resulted in a slightly different structure of the water column. In the periods of measurements recorded were diurnal rhythms in a series of parameters, caused by solar radiation cycles in the surface layers as well as fluctuations in the deeper layers under the influence of the internal tide. Meteorological conditions and changes in sea level are also described. The analysis included the principal component and correlation analysis between the measured and derived parameters in order to establish a link between the in-situ pigments and multispectral data. During both cruises diurnal vertical oscillations were observed in biotic and abiotic parameters. Chlorophyll pigments prevailed over other pigments preventing other pigments to be distinguished spectrally. Regression models for chlorophyll a were established from radiance and reflectance ratios. termohaline properties vertical migrations Adriatic South Adriatic Sea diurnal rhithm open sea internal tide Adriatic morje pigmenti plankton dinoflagelati vertikalna migracija dnevni ritem Jadransko morje pelagial slanost interno plimovanje true false true Angleški jezik Slovenski jezik Neznano 2024-08-05 08:22:19 2024-08-05 08:22:20 2024-08-08 03:51:10 0000-00-00 00:00:00 2012 0 0 Izvirni članki; str. 303-322 št. 2 Vol. 53 2012 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2012-12-15 574 0001-5113 2691919 RAZ_Morovic_Mira_2012.pdf RAZ_Morovic_Mira_2012.pdf 1 76CDF232A68A2B12E1154495BCF4B6D3 f6d2464e1a77b99658b47cc14a4a21c493ea5a09325748cb07870b8177af11ff 936120a6-52e2-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27912 https://acta.izor.hr/ojs/index.php/acta/article/view/330 0 8512cb91-52e2-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27911 Nacionalni inštitut za biologijo 0 0 0
