Last week we covered female aspects of reproduction in humpback whales, let’s turn our attention now to the boys.
The calm, protected, remote waters of the Silver Bank are an ideal location for North Atlantic humpbacks to give birth and spend the winter before heading to colder, but food-rich, northern waters. It’s also the winter hang-out and the place where gene pools mix, mates are selected and quite probably, though not yet witnessed, babies are conceived.
Some of the key points and fascinating facts about the male side of reproduction in humpback whales follow (with apologies for the anthropomorphizing!) Continue reading
The promise of a new day
Guests of Conscious Breath Adventures all know that every day in the Sanctuary for the Marine Mammals of the Dominican Republic is a new opportunity and you never know what you will see and experience as you set out on the whale boats to swim with whales. March 3, 2011 is just one remarkable example.
The morning dawned calm and clear, with no wind, waves or clouds to speak of, perfect conditions for finding and swimming with whales. After breakfast everyone eagerly geared up for what looked like a very promising day and they were not to be disappointed. We loaded into our whale boats and set off on our search. Continue reading
“The female whale or dolphin, in her role as mother, is the linchpin of cetacean population and behavioral biology”, Whitehead and Mann, 2000.
A look this week at why the Silver Bank is such a critical sanctuary for the humpback whales of the north Atlantic – having babies! Continue reading
Like a Hollywood movie, working behind the scenes of one of the world’s greatest natural works of art – the annual gathering of humpback whales on the Silver Bank – there are literally hundreds of critical players on the credit list. From protecting their breeding grounds, to keeping the oceans healthy and safe for their continued survival, many individuals and organizations play key roles in the welfare of whales.
The following eight entities are appreciated for their contributions to the success of the Sanctuary and for other marine conservation-related efforts. It is by no means a comprehensive list and there is no ordination; simply recognition of what they do, a thanks to all, and a call for on-going support. Please visit their websites, learn more, and get involved. Continue reading
Greetings to our readers here on Conscious Breath Adventures Latest News posts. The big news from Conscious Breath Adventures, and the subject of this post, is the launch of our new website, which we are excited to share with you. We are excited to share a fresh new appearance and the best look at the humpback whales of the Silver Bank that can be found anywhere on the world wide web!
www.ConsciousBreathAdventures.com is much more than just a website about swimming with humpback whales, it’s also a great place to see, watch and hear the whales. Our readers have always been gracious with their appreciation of our photographs, especially the photos we include in our popular weekly Cruise Reports posted during the season. With that in mind, and knowing that a photo is worth a thousand words, our new site features dozens of amazing high quality images that capture for you the sense of power, time and place that are a journey to the Silver Bank, before you make the trip yourself.

The oceans breathe for us (producing half the planet’s oxygen), provide for us (seafood is the primary source of food protein for over a billion people) and make us happy (unvalued but clearly priceless) – pretty wonderful, don’t you think? We need healthy oceans; it’s not an option. Helping to achieve that is not as removed from your every day actions as you might imagine. It starts with each of us, so put yourself in the picture starting today! Continue reading
It is estimated that over 300,000 cetaceans worldwide die each year as a result of entanglement in lost or active fishing gear. The sadness of this was brought home to all of us this week with reports of encountering a badly entangled whale, on the Silver Bank, seventy miles north of the Dominican Republic. Captain Gene’s report is below and we’ll share any updates on the situation as they arise.

Conscious Breath Adventures staff are currently on the Silver Bank in the Sanctuary for the Marine Mammals of the Dominican Republic where they operate under permit from the government of the Dominican Republic to offer soft in-water encounters with humpback whales. On Sunday February 12th, the first day of week three of the ten-week season, staff encountered, and made efforts to help, a badly entangled humpback whale. This report was received via satellite e-mail from the vessel, the M/V SunDancer II. Further information and photos will be available on February 17th when the vessel returns to port and internet access is available. Please contact Cloe Waterfield with any questions prior to that time. Continue reading
A special report on the 19th Biennial Society of Marine Mammalogy Conference in Tampa, Florida by Jodi Frediani.
Wow, a week of total immersion with whales, porpoises, dolphins, manatees, dugongs, sea lions, seals, sea otters and polar bears without getting wet! I just returned from the 19th Biennial (my first) Society of Marine Mammalogy Conference in Tampa, Florida. What an amazing week! Nearly 2000 people, including many of the top marine mammal researchers from around the world, along with students, educators, naturalists, and boat captains, came together to share the latest in scientific studies, seriously network and have a jolly good time. The theme for this year’s conference though was less than jolly, “Cumulative effects of threats to marine mammals: Challenges to animals, scientists, and managers.” Continue reading
Who doesn’t love dolphins, those cheery, bow-riding, promiscuous fellows, living the watery equivalent of the life of Riley? What their playful antics belie is that many of the marine mammals we share our coastal seas with are sick. Perpetually sick. They are plagued by cancers, viruses, pneumonia and other bacterial or yeast infections. They are sickened by harmful algal blooms; frequently deafened from shipping noise or seismic survey; and by exposure to toxic chemicals.
Beluga whales (the canaries of the sea) in the St. Lawrence Seaway are so contaminated, their bodies must be disposed of as hazardous material
Just as modern world diseases affect humans, our aquatic cousins are also succumbing to an increasingly toxic planet. Scientists like Dr. Greg Bossart at the Georgia Aquarium say that as top predators with large fat stores and long lives, marine mammals serve as “sentinels of ocean health” because they accumulate and concentrate the fingerprint of chemicals they consume. Understanding how they are affected by disease and contaminants in their environment (while noting they do not have the opportunity to emigrate or switch to a “healthier” diet) can help us become better aware of what we are doing to the seas.
