Spotted Dolphins around Bimini

DCP's Dolphin Research at Bimini & Xenia Brobeil Xenia Brobeil has begun working with DCP on her project studying the group dynamics of Atlantic spotted dolphins found on the Great Bahamas Bank, north of the island of Bimini. Xenia will be using photos and video to identify individuals and activity of these dolphins. Xenia's observations will provide baseline data for comparisons to data previously gathered by D.C.P. personnel studying the same species in the northern Bahamas.

Welcome!

Field Reports – Summer 2001 Welcome to our online field reports site. I look forward to sharing my field work and daily happenings with you. Let me acquaint you, or refresh you, with how these postings work. I will post updates about my research – data collection, preliminary analyses. I also include any unusual observations of dolphin behavior. And, I like to share a bit about my life in the field. About once a week, I will post answers to as many of the questions some of you post to the Ask Kathleen section of these reports.

Bahamas Summary … with a few other tidbits.

Bahamas Summary … with a few other tidbits. Well, I must say thank you for all your patience in waiting for the summary of my field research in the Bahamas. This past month has been crazy busy but I finally have been able to review the slides and video taken while at sea.

We saw some familiar faces (dolphin faces, that is) and two or three new additions to the study population of Atlantic spotted dolphins. It was a joy to get re-acquainted with these dolphins after my time in Japan.

Week 4 Summary

Dolphins, turtles, sharks and fish. We had 25 sightings this week – 13 of spotted dolphins, 5 just bottlenose dolphins and 2 with both species involved. We also had 4 turtle sightings and a few nurse sharks seen, and swum with! We spent 53 hours on effort/on watch looking for dolphins and about 85 minutes underwater with dolphins during 10 encounters and 10 short encounters. We even had a four minute swim with 7 bottlenose dolphins! They seem to be getting a bit less aloof with us up here on the banks.

Final Day at Sea

The sunrise was colorful and the breeze slight. Yesterday afternoon brought us to anchor just north of Sandy Cay. About 14 feet deep and clear visibility with no current. We went in search of conch and lobster for supper. But also it was fun just to observe the critters underwater. We did see a 6 foot nurse shark pass by within 10 feet of two of us while snorkeling. This morning brought more snorkeling and glassy seas. Almost mirror like – it was amazing.

So Much for Sleep

An increase in wind and sea conditions led to an early departure south. But everyone woke (or rather 'got out of bed') with a sunny attitude. And we had dolphins by the boat at about 8:00 AM. We were taken by surprise with having them so close to us. Literally about 2 meters from the stardboard side of the Hanky Panky. They turned out to be two mother/calf pairs. I recognized #42 and her calf but the other adult female will require photo-identification (i.e., matching of slides).

Slow to start …

… but then some old friends seen again. We had a slow morning, with no dolphin seen from the big boat. We did two dinghy searches – one in the morning and one in the afternoon. The morning trek provided us with two spotted dolphins. They were not interested in us or in bow-riding. We had a bit of a chop and a slight swell most of the day but these and the wind decreased in the early afternoon. Dolphins were sighted in the distance, in one of the many layered blue color bands of sea.

Happy Labor Day!

We spent the holiday underwater … Our day dawned clear and bright. Guess the old saying is true. Today was an awesome day for dolphin sightings! We had 6 encounters! and 10 sightings – our last at 21:43 this evening when a group of 5 dolphins swam by our stern. No light and no way to watch for other critters so no night swimming. But we were in the water so much today, I still feel water-logged.

Beginning our last Trip for Summer 2000

Little Wind, calm seas – yippee! Mostly green sea turtles coming up for air but one was a hawksbill. Way cool to see them gulping air at the surface. As is usual, we stopped at West End (now called Old Bahama Bay Marina) for diesel and lunch and then continued north. We stayed overnight on the dry bar. A location more protected from the swells of the Gulf Stream and where some of the dolphins hang out. Alas, the dolphins were elsewhere this afternoon. But we saw conch and lobster underwater and cooled off with a lengthy swim.
