It was so great to see you all today on the live stream! I hope you enjoyed it.
Today I introduced you to Katherine Cameron (PhD Candidate at SCRIPPS) who is working on the hydrophones and collecting the sounds, or vocalizations, the Nassau make. Below are two pictures taken yesterday of the Nassau swimming around one of the hydrophones as well as three sound files of different Nassau vocalizations she has recorded. Check it out and let me know what you think!
Here is a video clip taken this morning by one of the researchers who is measuring Nassau using laser calipers. Take a look!! Sure looks like a lot of fish. All the researchers seem to think that the big spawning event will happen tonight! Stay tuned!
Below are a series of pictures showing a microscopic camera attached to an Acrobat system, which holds the camera and controls the depth of the camera. Can anyone guess how and why REEF and the DOE would need a microscopic camera at the spawning aggregation site? What might they be studying?
Testing out the system
Those yellow wings help control the depth of the camera!
Researchers and scientists from REEF and the Cayman Islands Dept. of Environment are already at the spawning aggregation site on Little Cayman. Here are a couple videos of the grouper and scientists at work, collecting data!
Grouper Moon is almost here, so its time to start preparing your students for our live web-chats with scientists, researchers, and DOE staff who will be working at the Spawning Aggregation Site on Little Cayman.
I am here to support you in any way I can. Feel free to email me with questions about any of these activities. I am happy to help adapt activities to suit your student’s needs.
Every year, it seems we encounter at least one Nassau that appears different from any other we have seen before. Last year, it was a fish named Hula, who had a black belt-shaped pattern around the center of it’s body. The year before that was a grouper named, Lucky, who had a huge bite taken out of its back, yet appeared to be fully healed and happily partaking in the year’s spawning festivities. This year, we have found yet another Nassau that is unlike any we have encountered before. Take a look and let me know what you think!! We have not come up with a name for this grouper, so if you have a suggestion, feel free to
