Bimini 2011

Since 2001, DCP has been studying a group of Atlantic spotted dolphins (Stenella frontalis) in the waters around Bimini, a small Bahamian island along the Great Bahama Bank. Each field season has been extremely successful and, as we continue to collaborate with Bill & Nowdla Keefe's Wild Dolphin Adventures and Bimini Adventures, we now have over 90 individual dolphins in our Photo-ID catalog. In 2006, we also began systematic documentation of the common bottlenose dolphins (Tursiops truncatus) in the area. That fledging Photo-ID catalog as 38 individuals and we look forward to adding more!

The purpose of DCP’s research here is to analyze the group dynamics of dolphins found on the Great Bahama Bank, north of Bimini. Identification of individual dolphins and examination of their association patterns provides details and insight into their social structure and behavior. We will continue to examine if any of the identified dolphins match those individuals observed farther north, along the White Sand Ridge. To read more background information, click here .

The 2011 Bimini field season is once again being conducted by DCP Research Associate Kelly Sweeting . This will be Kel's ninth summer season in Bimini, and she continues to be there year-round, in hopes of collecting more non-summer data. As always, we are extremely excited about this year’s research. We look forward to the students who will join us and all of the dolphin swim guests we'll meet along the way.

Kel will be keeping folks around the world up to date on the research by posting regular field reports. Click on a posting below to see what we (and the dolphins) have been up to! Click on the links below for information on how you can support DCP's Bimini research program:

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. There were two calves in the group and at least one still had fetal folds, which I did not confirm until reviewing the photos. As always, this means lots of photo-ID work to come! Toward the end of the day we were greeted by two Atlantic spotted dolphins, Split Jaw (#22) and Tim (#69). It was great to see these guys surfing the waves and riding the bow.

Until next time,
Kel

 
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. As the bag re-boarded the vessel, dolphins appeared! At first we watched four bottlenose dolphins, surfing the waves as they disappeared and reappeared. Then, suddenly, there were more – a total of at least 10 bottlenose dolphins! We were able to enjoy the bottlenose dolphins for nearly 40 minutes before heading back towards Bimini. On the way, spotteds appeared! The seas were still too rough for a swim for us, but we enjoyed watching a single adult (un-named #40?) and three calves. Only one calf is likely hers; she would have been ‘babysitting’ the other two youngsters. We also got a quick glimpse of Romeo (#10) before returning to the dock just after sunset.

Looking forward to the rest of the windy week,
Kel
