Acoustic recordings at windy DE!

Kathleen and Kel just returned from a whirlwind trip to Nassau, Bahamas. We arrived on Friday 4 November and were back on a plane Tuesday 8 November. In this short time we continued our data collection efforts at Dolphin Encounters on Blue Lagoon Island. Although we normally use our MVA to record video and acoustic data, this time we brought along our newest piece of equipment, the SM2M. You might remember the SM2M from our summer work in Bimini and this was our first chance to test it in a more controlled setting.

Dolphins on the move!

Monday brought with it a last minute dolphin trip. As I waited on the dock for Bimini Undersea, I saw the rain clouds creeping in. Sure enough there was a shower, but it did nothing more than delay us. Soon we were departing the harbor under sunny skies. We did not have to wait too long and there they were – dolphins splashing in the distance. As we got closer we realized we were watching bottlenose dolphins.

Surfing dolphins

The winds have not really let up here in Bimini, but thankfully, dolphins like big seas! On Monday we headed out early, for a snorkel stop and lunch aboard the boat. We weren’t sure if we would see any dolphins, given the conditions, but we did get to watch some bottlenose dolphins from the boat. Tuesday followed a similar pattern, but included even more dolphins! We saw bottlenose dolphins on and off throughout the day, including this mother/calf pair.

A breezy October dolphin week begins

Sunday marked the start of an October dolphin week with Sea Crest Hotel & Marina. Although the winds were stronger than we would have liked, everyone was excited and happy to be in Bimini. We began with a brief snorkel stop and as soon as the anchor was set, we were greeted by a friendly young green turtle. Everyone was careful and respectful (no chasing, no touching) as we enjoyed the close views of this little ‘guy.’ About halfway through our search for dolphins, a passenger’s bag fell overboard. We stopped the boat and maneuvered to recovery it.

A Saturday Start

Saturday began a late season dolphin week with Bimini Undersea. I joined the group and very much enjoyed our conversations throughout the trip (thank you!). The guests took an early swim break, marveling at the ‘Bimini blue’ shade of the ocean. Not long after, we saw dolphins! At first we just saw two calves, but we were alert, looking for their mothers. Sure enough we saw them as the two (presumably) mother/calf pairs came together.

PAM deployment #2

On Sunday afternoon, I departed Sea Crest Hotel & Marina to redeploy Wildlife Acoustics’ SM2M passive acoustic monitoring (PAM) device. After getting our hands on this nifty gadget (thank you Wildlife Acoustics!) our first Bimini deployment was in July. The unit recorded successfully (phew!) and after taking a quick peek at the data, we made a few minor adjustments and waited for another chance to put it back at sea.

A late-season dolphin trip – yippee!

So, I had been wondering when we would get on the ocean after the outskirts of Hurricane Irene passed through. But, thankfully, Bimini Undersea got a trip together on Saturday! I very much enjoyed my time with the day’s passengers – and of course, the dolphins.
We departed feeling a bit uncertain about the weather. A few squalls had passed through earlier in the day and yesterday afternoon included a fierce thunderstorm.

A busy dolphin day!

Tuesday’s dolphin trip departed shortly after 14:00 and almost immediately we were in the midst of a group of 5 bottlenose dolphins. They were traveling south and there seemed to be a similar sized group keeping pace just to the west. We were given a rare treat with the bottlenose occasionally bowriding! At one point, the main group suddenly interrupted their travel for some activity at the surface. It gave us a chance to see one individual’s very distinct fluke (pictured here).

Where have you been?

On Sunday, we headed in search of dolphins and although the seas were a bit choppy, we were sure the enthusiasm of our mother/son passengers would bring a great day of dolphins. Unfortunately, we were all left a bit disappointed!
Monday’s trip began with a snorkel stop at “The Bimini Road” (aka “Atlantis”). Soon, we were in search of dolphins – and we searched, and searched, and searched. Thankfully, spirits remained high and we saw them at the last moment (which is beginning to seem like a theme!).

Interview with DCP’s 2011 summer interns

Ever wondered what it’s like to be an intern with the Dolphin Communication Project? Brittany McIntosh, Alexis Levengood, and Sabena Siddiqui share their thoughts and experiences as DCP’s 2011 summer interns. Each of them completed an office component at DCP’s headquarters in Connecticut before joining Kelly Melillo-Sweeting, Bimini Field Research Manager, on the beautiful island of Bimini, the Bahamas.
