Report on a Special Edition of the Journal of Marine Biology I was planning on something a little more lighthearted this week, maybe some fun whale facts and crafts for our younger whale-lovers. But, then the MARMAM digest arrived which included a link to a special edition of the open access Journal of Marine Biology,

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

International Marine Mammal Conference Delivers

Captain Gene Flipse — Sun, 11 Dec 2011 16:22:29 +0000

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

Canaries in the Coal Mine: Marine Mammals and Disease

Captain Gene Flipse — Thu, 30 Jun 2011 19:14:12 +0000

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.
We have long relied on the oceans’ vast diluting potential to get rid of our waste. For years the attitude has been that the solution to pollution is dilution. But marine mammals raise a cautionary tale. Far from dispersing, chemicals like heavy metals, oil byproducts, pesticides and flame retardants persist in the oceans and become hyper-concentrated in top predators. Just as we are more susceptible to illness when we are run down, scientists are concerned that chronic exposure to contaminants is lowering immune system resistance in marine mammals.
Hardy Jones of BlueVoice.org notes that topics discussed at biennial Society of Marine Mammalogy conferences now, more than ever, focus on contamination of the marine environment and impacts on the health of marine mammals, and even on humans. So, what kinds of diseases are we talking about?
Akin to our recent swine flu outbreaks, epizootics, which are epidemics affecting animals, are increasingly common. Thousands of dolphins, whales, sea otters and seals have died in recent decades in what are called Unusual Mortality Events. Many have been associated with harmful algal blooms like red tides. Some were triggered by outbreaks of viruses like influenza and the morbillivirus which is related to the measles agent. Also implicated is a bacterial infection called Leptospirosis.

Yeast infections, which we know can be triggered by an imbalance of natural bacteria, are particularly rife in a population of dolphins living along Florida’s east coast, with at least one in ten animals affected. The fungal infection, called lobomycosis, leads to ulcerated skin with gray and white lumpy nodules. The high prevalence and potential for it to be transmitted to humans, necessitates close attention to dolphins in this area.
Another zoonotic disease, (one that is transferable between animals and humans) is caused by a bacterium called Brucella. Widespread amongst marine mammals, when it outbreaks into the disease brucellosis it is implicated with skin lesions and brain inflammation. Cases in humans are linked to consuming raw seafood.
Cancer in marine mammals, once rare, looks to be on the increase. Triggering agents like papillomaviruses are linked with genital, tongue and skin cancers in bottlenose dolphins and manatees, as they are with cervical cancer in humans.
While it doesn’t paint a pretty picture, we are getting better at assessing diseases in marine animals. We’re certainly talking about the topics more. Projects like the multi-year Health and Environmental Risk Assessment, run by Florida Atlantic University’s Harbor Branch Oceanographic Institute, are studying live dolphins in the wild. So, we’re starting to understand the real world implications of environmental stressors like pollutant run-off. What is just as crucial, though, is what are we doing to address them?
Contaminants reach the oceans primarily from rivers, streams and outfalls that comprise water management systems and waste disposal for the 40% of us, globally, that live in the coastal zone. In the words of the famous animated clownfish, Nemo, “All drains lead to the ocean.” So how we live does make a difference. Here are just a few choices we can make to lessen the toxic legacy we leave to the oceans and to ourselves.
1)    Opt for organic agricultural techniques both for food items and in our own backyards, minimizing the use of pesticides, herbicides and inorganic fertilizers.
2)    Choose natural, non-toxic household products.
3)    Dispose of all chemical waste properly. This includes oils, medicines and paints.
4)    Use and promote the use of green energy. When coal and oil are burned contaminants like mercury are released into the atmosphere and deposited in the oceans.
5)    Support and encourage ocean leaders. We need stronger legal controls on industry waste disposal and pollution. And we need to protect coastal habitats, like our natural filtration systems—wetlands and mangroves.
Marine mammals touch a chord with so many of us. On this subject, as with many, it’s apparent that they still give back, because the take-home lesson is that opting for a healthier lifestyle is much better for us, and for them.

Happy World Oceans Day! How to help, every day…

Captain Gene Flipse — Wed, 08 Jun 2011 14:21:20 +0000

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 life as you might imagine. It starts with each of us, so put yourself in the picture starting today!

Every day actions by every day people DO make a difference for the oceans

Here are ten free things you can change about your day, every day, that honor the world’s oceans. (P.S. you will save money and be creating a healthier planet for you and your children too).
1)   Use water wisely: avoid vigorous faucet running, take short showers, save excess drinking water for the plants.
2)   Turn everything off – any non-essential electronic item – and the temperature setting on your air conditioner up (or heat down) before you leave the house (or go to bed).
3)   Save power; you reduce carbon dioxide emissions and slow ocean acidification. You can leave the dishwasher run until night-time (daytime hours are often peak electricity demand) or air dry a load of laundry for example.
4)   Walk, bike, take the bus, or stretch out those precious gallons of gas by slow steady driving with a fairy-like light foot.
5)   Forgo plastic; bags, bottles, packaging, take-out containers, straws. Take reusable items, be creative and be a role model.
6)   Recycle. No excuses. It saves energy and demand for raw materials. And don’t forget to buy recycled products.
7)   Lighten your chemical footprint. As Nemo says “All drains lead to the ocean.” Here are some ideas: properly dispose of expired medications, buy organic produce, switch to phosphate free laundry and dish soaps, ask your landscapers to eliminate or minimize their use of fertilizers.
8)   Choose only sustainable seafood; check Seafood Watch and download an app. And make as many local food purchases as you can.
9)   Pick up some litter – especially if you visit the beach.
10) Take a moment to appreciate the big blue. Read an ocean themed book with your kids, watch a documentary, check out some cool photos on-line, visit the seashore (or better still get wet) and just say: thank you!

Happy World Oceans Day!
