Half way there

It has been a crazy and very full on 6 months of taught masters, covering a great range of interesting and wonderful topics. I honestly feel as if I have learned more in the past 6 months than I did in my 3 years of undergraduate, although being awake through lectures probably contributed to that! I've now gained professional certificates in sea survival, VHF (very high frequency) radio communications, power boat handling, and first aid. I've sat two sets of exams, written a long list of assignments, reports and papers, and have recently returned from my second adventure to Millport on the isle of Cumbrae off the west coast of Scotland for a field trip to study benthic organisms and the distribution and size differences in the edible periwinkle (Littorina littorea).
Now that the taught portion of the course has come to an end, I have thrown myself straight into working on my thesis which currently has the provisional title of:
"The comparative analysis of passive acoustic CPOD detections with seasonal visual observation effort of dolphins within Broadhaven Bay, Ireland."
This study requires me to move up to Belmullet, a small town in County Mayo, where I will spend 5 months helping Coastal Marine Research Centre with field work whilst working on data that their cliff-top observation teams and passive acoustic CPOD stations have recorded since 2009.
This means, for the next few months I will be staring at screens to determine if sound files of click trains are indeed the echolocation of dolphins, or if the software has falsely classed them. The main false-positive detections come from porpoise "masquerading" as dolphins, where the narrowband frequencies of porpoises have been ignored and thus have been classed as a dolphin which although share the higher frequencies alongside porpoise; their frequency range extends far below as well.
