Geothermal measurements in the Tyrrhenian Sea

Geothermal data obtained during Cruise 12 of the R/V Vityaz-II and published data on heat flux of the Tyrrhenian Sea are analyzed. The thermal field is related to principal tectonic structures of the basin. Distribution of heat flux indicates that the initial stage of rifting occurs in the central basin of the Tyrrhenian Sea.

Physical oceanography from the Drake Passage and Bransfield Strait during Meteor cruise M56

This data publication is the electronic version of hydrographical and fluorometric data which were taken during the Antarctic cruise ANT I No. 56 of 'Meteor' from November 13th to December 18th 1980. The data were measured by means of the Optik Sonde (OS) of the SFB95. The data set contains the temperature and salinity profiles, the profiles of attenuation (extinction) coefficient at 670 nm wavelength and the fluorescence of chlorophyll expressed as chlorophyll a concentration values.
