This morning brought another early session. I collected about 30 minutes of data before 7:30 AM when our team was preparing to head out for an early morning dive. Hector and Han decided my fins were the best thing since sliced bread and nibbled on them. It’s a bit disconcerting to have to stop and elevate my feet into the air to get the dolphins to ignore me.
The afternoon brought a chance to deploy the Song Meter SM2M Marine, from Wildlife Acoustics (see photo). John, Nicole and Nate helped me with the deployment. John filmed from below while Nate and Nicole handed me the SM2M with the 24 pounds of weight for placement.
The SM2M will let us record dolphin sounds over each 24 hr period from today to Friday. We attached the passive acoustic recorder to a piling in the dolphin pool and watched as several of the younger animals and their moms swam by to check out the yellow tube! I think they were more interested in John’s bubbles from SCUBA, but a least one individual supervised my tightening of one strap to secure the recorder to the piling! We got quite a bit of data today and both Nicole and I (at least) are getting to know the scratches and other ID marks on the younger dolphins, as well as remembering the marks on the older individuals.
Tomorrow brings more data collection!
