Just like the first day of school and the first piece of art you bring home, your first paper as a scientist is a pretty big deal and I am super excited about mine. This paper will always be very special to me as it is the first piece of work that I a fully sending out into the world with my colleagues to be continually and forever more judged by my peers.
This paper is also from a project exceedingly close to my heart it is a topic that I have been interested in for a long time and the road to its completion was not always smooth but what is life without a challenge and out of it has come a piece of work that myself and my colleagues are exceptionally proud of.
The paper is:
Wellard, R., Erbe, C., Fouda, L., Blewitt, M., (2015), Vocalisation of killer whales (Orcinus orca) in the Bremer Canyon, Western Australia. PLoS ONE 10(9)
It is the result of two years of data collection to look at the different vocalisations produced by the killer whale population in the Bremer Canyon, Western Australia. My involvement was full time in the second year, where I was involved in data collection, data analysis and manuscript preparation.
What did we see I hear you wondering out loud…? Well we used K-Means clustering analysis to group the calls into categories with the most similar acoustic features. We looked at whistles (frequency modulated, tonal sounds, with or without harmonic overtones) and burst pulses (consist of rapidly repeated pulses with inter-pulse intervals shorter than in echolocation click trains). We did also detect clicks while collecting data however they were not a focus of this paper. Through the analysis the calls have been separated into nine different Bremer Canyon call groups four for whistles, three for burst pulses, one for whistles that are pulsed in the middle, and the final group consists of burst pulse to whistle transitions and vice versa.
This paper is unique in that it is the first paper to describe the vocalisation of killer whales in Australia. The vocalisations are the topic of my colleague Bec Wellard’s PhD and there will, I am sure, be many more exciting developments to come in the realm of Australian killer whale acoustics. My focus is now shifting more in the direction of ecology, population studies and conservation so keep your eyes peeled to see what comes with that.

How did you feel after your first paper was published? Did you keep a close eye on citation indexes and metrics? Was it a thrill or a relief once the paper was submitted and accepted?
I know I am definitely looking forward to working fully on my next paper now!
