I collected my water samples from a lake in Central Park in Ormond Beach. It rained quite a bit before I collected my samples so they may have gotten diluted a bit. In addition, there is a lot of ongoing construction happening on the street adjacent to the lake. Materials and debris from this have probably gotten swept into the lake and could have an effect on the amount of suspended solids in the sample as well.
As for my project, I'm still in the process of tweaking my scientific question. It's definitely going to involve manatees and the sounds they emit but I'm still working out the details. As far as materials go, the things that I can think of that I would need would be a hydrophone and the computer software to analyze the sound recordings. Oh and some manatees of course!

I downloaded the software ISHMAEL (Integrated System for Holistic Multi-channel Acoustic Exploration and Localization), and played around with it a bit. I downloaded some of the audio samples from the online library and opened them in the program. I couldn't figure out how to get the sounds to play but I did get the waveform (curve showing the shape of the sound wave) and spectrogram (visual representation of the spectrum of frequencies in a sound) to appear. I'm definitely going to have to consult the software manual! I also came across and downloaded a sound analysis software called Raven. On this software I was able to get the sounds to play. I thought this software was cool in that it allowed me to view two sound samples side by side to compare them.
Good thinking with trying out Ishmael. I guess using that, you would be able to upload your own manatee sounds and review them on there. Good job (:
ReplyDeleteReally nice job, Michelle! You very nicely described the words waveform and spectogram; please go back and bold those terms.
