Notes: Cyclohexadien-(1.3)-dicarbonsäure-(1.4)-dimethylester wird photochemisch mit 60-70% Ausbeute zum Bicyclo[3.1.0]hexen-(2)-dicarbonsäure-(1.5)-dimethylester (XV) isomerisiert. Durch Variation des Anregerlichtes sowie der Reaktionstemperatur lassen sich der offenkettige Hexatrien-(1.3.5)-dicarbonsäure-(2.5)-dimethylester (XXVII) sowie der mit XV isomere Bicyclus XXII als Zwischenprodukte nachweisen. Die Photoisomerisierungsstufen XIV → XXVII sowie XXII → XV sind bei vergleichsweise sehr niedrigen Aktivierungsenergien thermisch umkehrbar. Entgegen unseren früheren Angaben vermag Diazomethan die Valenzisomerisierung zum Bicyclo[2.2.0]hexen-Derivat XXIX nicht zu sensibilisieren.

Description: AWI's autonomous underwater vehicle PAUL – Polar Autonomous Underwater Laboratory (AUV Bluefin 21) was deployed during R/V Polarstern cruise PS99.2 in central Fram Strait. The scientific payload included a pressure sensor (Paroscientific Inc.), a pumped CTD (SBE 49 FastCAT), a dissolved oxygen sensor (SBE 43), a nitrate sensor (SBE Deep SUNA), two fluorometers for chlorophyll a and colored dissolved organic matter (Turner Design C7-c and C7-u), an upward looking sensor for photosynthetically active radiation (PAR, Satlantic PAR-log-s), shear and temperature microstructure profiler (MSP) from Rockland Scientific Inc., and an 300 kHz RDI acoustic Doppler current profiler (AADCP, AUV based Acoustic Doppler Current Profiler). Additionally the vehicle carried a water sample collector to gather a maximum number of 22 samples with a volume of 220 ml each. The AUV conducted high resolution profiles between the surface and 50 m water depth. Between the profiles the AUV was diving along constant depth for a few hundred meters to allow for ADCP measurements of the water column above. A small CTD SBE 19plus was deployed manually from a Zodiac driving in parallel to the AUV track.
