Just Another Day in Paradise!

Our day began with two cups of coffee and a boat taxi ride to Bailey’s Key. And, once again, the dolphins were right there! We began the day with more dolphin behavior observations, noting a bit more detail than yesterday. It was a bit easier to ID some of the dolphins – Polly, Hector, Han, Paya, and Gracie were all readily visible to us this AM! The dolphins were frisky this morning – there was lots of splashing and socializing ongoing this AM providing lots for us to document and note.

 

After our delicious breakfast, we had an informative physiology talk/discussion. We learned that respiration rates don’t cut it to estimate metabolic rates and that you cannot take inaccurate measurements to make an accurate prediction of a data point. The assumption that every time a dolphin or marine mammal comes to the surface they are taking a breath is wrong based on our field observations from the past two days. The assumption that they are going to their max limit with each dive is a fallacy. And, the assumption that with each breath they take in the same amount of oxygen is also wrong. (further explanation to come on the last two assumptions by the end of the week).

 

We were given our first assignment today – it is to come up with a way to measure something physiological based on behavioral observations. This is something we will try to put into practice on Thursday and Friday. We also learned a bit more detail about the array (see photo) – how to connect the camera and about the controls.

 

Our almost last activity of the day was to go snorkeling from a boat. We went to Mud Hole and snorkeled in blue water – odd as it sounds! The fish ID talk came in very handy (Thanks Pete!). We saw trumpet fish, a school of tang, butterfly fish, a green moray eel, squirrelfish, wrasse, parrotfish, and coral (brain coral and elkhorn). We also saw sand dollars, hermit grabs, conch shells, and sea fans. It was a good snorkel!

 

After snorkeling, we rinsed off in the pool and began our roundtable discussion regarding our first assignment! The pool water was chillier than the ocean, especially once the sun dropped behind the palm fronds! Chelsea noticed she was much less buoyant in the pool than in the ocean!

 

Until tomorrow!

 

Cheers

P.S. we picked up our bracelets to support the Roatan Marine Park! :-)

 

The Beginning – our first full day in the course
02 Jan 2017

The Beginning – our first full day in the course

We had our first introduction to the dolphins after our boat taxi ride to Bailey’s Cay. The ride was full of anticipation and culminated with Kelly’s reaction, “oh! They’re right there!” They were so close and within reach, not behind 6 inches of glass! There did not seem like there could be 23 dolphins in the enclosure … maybe 12, but then we got to see the different dorsal fins. They swam close to our positions and checked us out. It was definitely hard not to interact with them more.

We spent a few hours after data collection on photo-ID learning about their different scars and marks. We also discussed the different behaviors we saw on the first research dive of the day. After lunch, we returned to Bailey’s Cay and met some of the trainers and dolphins close up. The morning session had us not really seeing all the details Kathleen pointed out about individual IDs but sitting with the trainers and actually meeting a few of the dolphins clarified the scars and marks and the tiny details. It was fun meeting the dolphins. “Carmella is really shy but eventually took the fish from me,” said Micaela. Mrs. Beasley was more finicky with each fish. Gracie is a ham and thoroughly enjoyed the attention. Calli was stinking cute and had a distinctive bite because her mouth does not close all the way on the sides. We also got to watch the calves playing and they tussled with each other while their moms ate.

Our day wrapped up with a very informative fish ID talk. In this talk it was not so much individual ID for the fish but species ID. The talk was a great prep for tomorrow’s first snorkel trip. We feel quite prepared to recognize all the species, maybe not the 500 on the reef but maybe a dozen or so! And, we learned about all the conservation and good work of the Roatan Marine Park. We will definitely be supporting their mission and getting our bracelets!

Until tomorrow!

Cheers

Wrapping Up 2016 and Ringing In 2017!!

Happy New Year’s Eve!
DCP/Kathleen is finishing out 2016 in and welcoming 2017 in research style … with a week of data collection and a college field course on Roatan at Anthony’s Key Resort! And, thanks to John, the MVA2 has new hydrophone arms that allow for the MVA2 to be in carry-on luggage (small black bag on left)! The arms are back to the original design and made of PVC - the green my added touch! I’ll be sure to post a photo of the MVA2 all assembled in a day or two so you can see the full effect of the new arms.
Today is travel day! I’m writing this post as I sit in the airport waiting for my flight to Roatan. I’ll be joined by students from Colorado State University (CSU) and the University of Southern Mississippi (USM) for a week of data collection and study into dolphin behavior and physiology. We’ll be merging the disciplines of animal behavior and exercise physiology. Dr. Shane Kanatous, Biology at CSU, is joining me and we’ll be co-teaching this week’s program. Stay tuned to our blog for daily updates from the field!
Cheers!

Name #102

Give a name to #102

 DCP ID#102 is a juvenile, female Atlantic spotted dolphin. DCP has been observing her off the coast of Bimini, The Bahamas since 2013. She is recognizable even before we enter the water, as she has two distinct notches in the center of her dorsal fin. In 2013, she also suffered an injury to her peduncle. Though this injury healed very well, it has left a permanent scar. Neither of these markings slow her down though! She is a busy dolphin, seen in a variety of social groups. Like "Seabeagle" (ID#106), un-named #102 has also been observed with fellow juveniles, Inka (#93) and Paul (#99).

Now that you know a bit more about #102, what name do you think suits her best? The cost to give a name to #102 - a rare and unique opportunity - is $750. If you've got a name in mind, you can purchase your name-a-dolphin kit today! After you make your purchase (using PayPal) we will contact you for more information about the name you've chosen.

#102's new name should be

IRSC Semi-Annual Undergraduate Research Symposium

On Friday, Kathleen was back on the Indian River State College campus, this time to attend the IRSC Semi-Annual Undergraduate Research Symposium. Kathleen was supporting Ashley Locher, who participated in the Service Learning program between IRSC and DCP in May and June 2016, and continued through the summer and early fall to develop a presentation from her experience for the program at IRSC.  Ashley’s poster presentation title was: Comparative studies on pectoral fin contact behaviors between wild and captive dolphin species. Ashley stood by her poster during the three-hour program and skillfully answered questions from members of the audience about the research and results. Ashley graduates this fall with her degree from ISRC. Congratulations to Ashley for a well-done presentation and for finishing her degree!

In this photo, you can see the 2016 IRSC/DCP Service Learning group as they work through photo-identification methods and techniques.

DCP RIMS October 2016 Field Reports – Summary

DCP RIMS October 2016 Field Reports – Summary

Before I wrap up the week, I thought I'd share a photo of the SM2M deployment ... though this image is from 2-3 years ago! When I deployed the SM2M yesterday, the underwater visibility was such that at 24 ft deep, I could not see details of the surface, and vice versa. So, no photos were taken during yesterday's deployment!

We had a good week this year! Our group got in lots of dives and much bottom time. And, I was able to collect 3 hours of data with the MVA2 and a similar amount on the front-facing GoPro. The GoPro gives us a wider field of view such that we can confirm IDs and some of the behavioral exchanges. I'll be busy with video logs and photo-ID for these data over the next several months!

We also deployed the SM2M to record dolphin vocal behavior over the next ~2 months. We'll record 10 minutes of data for every hour while the passive acoustic recorder is deployed. Data analysis comes after we recover the unit.

Stay tuned to the DCP Dolphin Gazette newsletter for updates on our data analyses. And tune in back here on New Year's Eve when I return to Roatan and Anthony's Key Resort with a field course with students from Colorado State University and the University of Southern Mississippi!

Cheers

Kathleen

TGIF? Last Day for Data Collection!
31 Oct 2016

TGIF? Last Day for Data Collection!

The rainy season seems to have arrived to Roatan! Another rain-filled evening dawned to overcast skies and elevated wind speeds! The current was also quite strong! We made the trek over to Bailey's Key with the hope of collecting data with the MVA2. The dolphins were social and seemingly game! I was game, my crew was certainly willing to make surface observations. Mother Nature (or is it Father Neptune?!) had other ideas! The underwater visibility, even viewed from above water, was not good! The current was again strong and a squall was on the horizon.

So, we decided to wait an hour or two ... maybe the visibility would improve?

It did not. But, our group had a dolphin encounter and met Polly and Tilly at the beach. And, with Bill and Ron's help, I prepared the SM2M for deployment. Since I am returning to Roatan with a college group for a field course in animal behavior and physiology on 31 December, we received permission from Eldon and AKR to leave the SM2M (our passive acoustic recorder) out recording for the next two months! I secured it with 24 lbs of weight as well as tying it to a piling. The dolphins were VERY interested in the SM2M and me ... and maybe thought they were being helpful when pulling at my regulator hose and fins!

Today was a good day, even though no video were collected. We wrap things up tomorrow for the return trip. I'll provide a summary of the week tomorrow.

Cheers

Dodging Rain Drops ... at least for the research!
27 Oct 2016

Dodging Rain Drops ... at least for the research!

Rain greeted us just before sunrise ... leading to a delayed research data collection session. I entered the water at about 7:40 this AM and had a good 30 min session observing the dolphins. The calves were receiving much attention from almost all of the dolphins. Of course, Mac, Lenca and Champ still thought my fins were the best toy available!

I was able to record Gracie and Alita on several occasions and we confirmed which calf went with each mom on viewing the video this afternoon. The dolphins were quite vocal and very social with one another. The underwater visibility was so-so but there was decent light and a visitation by the sun when I was in the water. The photo here shows a good view of Anthony's Key ... though we're not sure which end the pot of gold my be under!

Several of the divers in our group did a shark dive this morning. They swam among more than a dozen Caribbean reef sharks and weathered choppy seas and swells and rain to meet these sharks! The second two dives saw underwater visibility decrease to almost nothing. Still, the shark dive provided much fodder for discussion during dinner!

Tomorrow is our last day for data collection and we'll deploy the SM2M for collection of dolphin vocal behavior over the next two months. Though we've had more rain than was expected, it's been a good week for underwater time and data collection!

Until tomorrow,

Cheers
