Cruise Blog M141-2 (Transit Ponta Delgada - > Varna)

UFO - cruise news: After two exciting weeks on board RV Meteor, we have successfully collected water for U isotope studies of the Mediterranean Sea deep water. We sailed roughly 3000 nautical miles from the Azores to the Black Sea and collected water to a depth of 3500m in 7 Stations. There where numerous highlights both scientifically as well as touristically. If you want to learn more get in touch with the team members Marleen Lausecker, Evan Cooper Border, or Norbert Frank. Many thanks to the Captain Detlef Korte and his excellent team. We are eager to come back in October 2018. Find our preliminary short cruise report here

From the 5. October to the 19. October the RV Meteor transits from the Azores to the Black Sea through the Mediterranean Sea. We, Evan, Norbert, Marleen and Patrick join the cruise to collect seawater that would allow high precision measurements of geochemical constituents, in particular the natural isotopic composition of U. It has been proposed that the natural 234U/238U ratio may serve as a tracer of continental weathering. We intent to collect water in a few places study the difference between Atlantic and Mediterranean seawater. Hopefully, this will allow to obtain a new fingprint of Mediterranean continental weathering. A second part of our scientific program concerns the measurement of the solar attenuation including the effect of water vapor. This part will be conducted by a colleague from the NASA's AERONET group. Find more information about the solar attenuation measurements on the webside of the maritime aerosol network. You will find updates here every week as well as the final report. Stay tuned

The Labs and instruments

We make use of numerous techniques to study, describe, store and document the material we work with. Our repository contains corals and speleothems from all around the world. Once prepared we use mass spectrometric instruments, such as thermal ionization mass spectrometry and laser-ablation coupled to multi-collector inductively coupled plasma source mass spectrometry (short: LA-MC-ICPMS) or high sensitivity inductively coupled plasma source quadrupole mass spectrometry to measure element and isotope composition of our samples. Look up the service section for the analysis we can provide through scientific cooperation and if you want to learn more see the publications or get in touch .

Images from research cruises and field trips

The team participates in field work to collect samples from all around the world. The photos are snapshots providing a glance on what it is like to be on sea or to take part in a search for new speleothems, calcareous tufa, sediments, rocks etc. The remotely operate vehicle (ROV) Victor 6000 belongs to the marine research infra-structure IFREMER and all rights on using those photos belong to IRFREMER and the cruise chief scientist. Other equipments are sediment traps, long gravtiy or box cores and the new ROV - Squid from Marum. Finally, water is collected using conventional CTD (Conductivity=salt; temperature; and depth) - Rosette with 24 Niskin bottles of 10 litres each.

Team events ...

We celebrate celebrate our scientific success and invest in a strong team through group events. 2016 we have visited the waterfalls of Bad Urach . In 2015 we have spent a few days on scientific writing funded by the Wilhelm und Else Heraeus-Foundation for which we stayed at the KLJB Bildungshaus Fiegenstall . The year before we went caneoing on the Elsenz and bowling . and sometimes we just celebrate remarkable events such as the 40 years of environmental physics.

Movies ...

Here we propose a selection of movies that cover aspects of our work or the scientific field.
