Calvin: I think we’ve got enough information now, don’t you?
Hobbes: All we have is one “fact” you made up.
Calvin: That’s plenty. By the time we add an introduction, a few illustrations,
and a conclusion, it will look like a graduate thesis.

I would like to thank my supervisors and the members of my thesis committee for
their support and helpful advises: Tim Jennerjahn, Venugopalan Ittekkot and Kai
Bischof as well as Matthias Zabel and Carlos Veiga de Cavalho.

Great thanks goes to my terrific working group: Gerti, Luci, Claudi, Ingo, David,
Shilly, Anne and Daniela. Thank you for helping and inspiring me and for all the
great advice you have provided within the last three years!

Glomar is gratefully acknowledged for the exciting courses they offer and for giving
me the chance to attend the ATBC conference.

A very special thanks goes to the ones who helped me in the field in Indonesia and in
the laboratory at ZMT: Carolin Herbon, Anne Buhmann, Daniel Wangprasseurt,
Janina Korting, Ari Budi Santoso, Angela Maria Oviedo, Dana Pargmann, Alexandra
Ostmann, Sonja Kleinertz as well as to the students from UNSOED Yuni, Andhi,
Andri, Dendy, Zico, Edwin, Jefri, Rati, Dutha and Hendri and of course our great boat
drivers Pak Hendro and Pak Mardi. Thanks so much – without you guys I would have
never made it!

Not to forget our lab technicians at ZMT: Matthias Birkicht, Dorothee Dasbach,
Christina Staschok and Silke Rick. Thanks for your help and support – especially to
Matthias, who was always there when I needed him.

Thank you Petra Käpnick, Silke Eilemann and Gaby Böhme for organizing the flights
(and for bringing me back ), Visa, travel expenses, etc., Uli Pint for the IT-support,
Ago Merico for trying to improve a PhD candidates world as well as our new library
fairy Christina Fromm. You are all doing a great job!

Thanks to Edy Yuwono, Hussein Sastranegara, Erwin Ardli and Claudia Schultz. I
cannot say the field trips to Indonesia were always easy. Nevertheless you always
tried to help and improved things!

As I am not a statistics expert I would like to thank Werner Wosniok for his inspiring
ideas and his patience with all my statistic problems!

Thank you Martina, Gerti and Steffi for proof reading my thesis and for the advice
you gave me.

… and last but not least …
The support for my PhD thesis is gratefully acknowledged above. But without my
husband Alex and his great family Renate, Hans-Jürgen, Saskia and Kathi, my sister
Frauke, her boyfriend Thorsten and our dad Werner and his wife Christine as well as
my friends Marion, Artis, Régine, Mirko, Rocco, Peggy, Hendrik, Steph, Caro, Anne
and Sarah I would never have made it. No words can describe how thankful I am to
have such wonderful friends. Thanks for showing me everyday that friends are much
more important than work! Or to say it in V. Nabokov´s (1899-1977) words: „Sobald
man zum Thema von Dissertationen geworden ist, lebt man nicht mehr lange.“ I love
you!
