Woke up in the early hours worrying about a chapter in my PhD thesis
Published in 1987!!!!

It is #IAmABiologist Week - organized by @rsb.org.uk
Aim is to highlight the diversity of roles in the biosciences
I study organisms that live in Antarctic, Arctic and Baltic sea ice
over the years has required many curious moments - including sweeping ice floes in the middle of the Weddell Sea?

The 4 editions lined up on the shelf are a proud moment since they represent a project that started in June 1999 when I wrote the first book proposal for an introductory book covering several disciplines of sea ice research.
Possibly a 5th edition in 2032, which is when I plan to retire..........
