Ocean Noise and Right Whales

In a recent paper published about right whales, stress hormones and ocean noise, it was found that after the September 11, 2001 terrorist attacks and subsequent decrease in shipping and air traffic for about 4-5 days and therefore less ocean noise, the stress hormones in right whales dropped.

We often don't think about how much noise we are putting into the ocean and when combined, prevents whales from communicating as easily as when noise levels are lower.  Hearing is probably one of the most important senses in whales.  Reducing ocean noise should always be a priority, however, a consequence of quieter vessels may be a reduced detection rate of vessels by whales.  But as long as there is some noise onboard and in a quieter ocean, it would be hoped that the whales would still be able to avoid collisions.

Priorities should always be for quieter engines but there has been concern about quiet electric cars and the safety of pedestrians if they don't look before stepping off the curb relying instead on car noise to alert them to oncoming cars.  However, if stress levels are reduced in whales with reduced ambient noise then perhaps the same would happen in humans if we live in a quieter environment.

Wonders of the Oceans

'Wonders of the Oceans' is a learning module aimed to teach 8-12 year olds the importance of conserving aquatic resources through responsible fisheries and aquaculture. It includes 8 major themes and a total of 17 lessons. The website is provided by the Fisheries and Aquaculture Department of the Food and Agriculture Organization of the United Nations - http://www.feedingminds.org/fmfh/fisheries-aquaculture/wonders-of-the-oceans/en.

Brian Skerry - National Geographic Photographer

Brian Skerry made a TED address in May. He has photographed many marine species and has gained an insight into the marine environment. Certainly worth listening to:

Earth Day

April 22 is Earth Day, begun in the United States in 1970, it is often heralded as the beginning of the environmental movement. The first International Earth Day was celebrated in 1990.

The http://www.earthday.ca/ website has a resource section with everything you need to plan, organize and participate in an Earth Day, Earth Week or Earth Month event, in a series of downloadable PDFs from their Earth Day Project Planner. But don't think of it as one day a year but the start of a new outlook on the Earth. These resources are also wonderful if you are planning an activity or project to use for the Right Whale Steward program.

Here is a great list of Top 10 Actions from the www.earthday.ca website:

1 Smart Shopping
• “Buy what you need, not what you want”
• Consider renting and borrowing things that are seldom needed
• Buy used items from garage sales and second-hand stores

2 Simple Savers
• Replace incandescent light bulbs with compact fluorescent bulbs
• Use aerators on faucets and shower heads
• Weatherstrip windows and doors

3 Transportation Alternatives
• Walk, cycle, car pool and use public transportation
• When driving, reduce idling and maintain correct tire pressure
• Consider car sharing programs or renting

4 Food Choices
• Choose local and organic foods that are in season, and support local food producers
• Eat less meat

5 Washing and Drying
• Wash full loads of clothes in cold water and hang to air dry

6 Heating and cooling
• For summer air conditioning, set your thermostat to 24°C or 25°C
• For winter heating, set your thermostat to 19°C or 20°C
• Install ceiling fans and programmable thermostats

7 Close to Home
• Vacation, travel and work as close to home as possible

8 Bathroom Basics
• Take short showers instead of baths
• Close water taps while brushing your teeth

9 Careful Cleaning
• Choose natural, non-toxic cleaning products
• Make simple, natural cleaners with ingredients like vinegar, baking soda and water

10 Don’t Discard
• Donate, reuse and recycle items before throwing them into the trash
• Harmful materials like chemicals, batteries, electronics, etc. should be taken to local hazardous waste depots or recyclers

Lights Out Canada, Schools - April 22

Lights Out Canada is a national event during which schools across the country turn off their lights and spend the day learning about climate change and what youth can do to take action. Materials provided include comprehensive lesson plans, step-by-step participation guides, and visual aids. The Lights Out Canada Challenge is set for April 22, 2010, Earth Day. The Challenge is twofold:
  • to reduce measurably and significantly school electricity use during the 2010-11 academic year without compromising either educational or extracurricular activities, and
  • to help schools shift to more environmentally friendly "green" electricity which has virtually no carbon footprint.

Almost 150 schools have registered for this year's event already! For more information, visit http://www.lightsoutcanada.tpweb.ca/

Learn About Sounds and Right Whales

The Discovery of Sound in the Sea website http://www.dosits.org/ has been redesigned to provide an interactive experience. They have sound clips from North Atlantic right whales www.dosits.org/audio/interactive/#/52 and a very detailed section on sounds and marine animals including mammals:


  • How they hear sounds

  • How they use sound when they are feeding

  • How they use sound to communicate

  • How they use sound to navigate

  • What are the effects of anthropogenic (human produced) sound on marine mammals

  • How can one measure the reaction of marine mammals to sound

There are also more advanced discussions of scientific methods.

Sound and hearing are very important to marine mammals and a recent study has shown that right whales compared to the 1970s are shouting (frequency shift) because of the increased level of noise in their environment from human sources. The paper was in the Journal of the Acoustical Society of America, Volume 122, Issue 6, pp. 3725-3731 and is entitled "Short- and long-term changes in right whale calling behavior".

Reducing the amount of anthropogenic noise in the marine environment is a bit of a Catch 22. Given that fast moving vessels are problems for right whales, completely silent fast vessels may pose a greater risk than one making low noise. Moreover, most noise from a vessel comes from the propellers and the bow is a relatively quiet zone which may confuse right whales and other marine mammals into thinking they are safe at the bow of large vessels. Using sound deterrents on the bow are unproven. Experiments playing sounds to right whales produced inconsistent results and when the whales did respond to a particular sound, the whale stopped what it was doing and came to just below the surface to listen to the sound. This, of course, would bring the whale into a greater danger zone than if the whale had not responded to the sound. Scaring whales away from vessels is a complicated problem. It is, however, very important to reduce any masking effects of marine mammals communications so they are able to hear each other over broad expanses of ocean.

National Wildlife Week Walk for Wildlife

National Wildlife Week begins April 4. A national campaign to Walk for Wildlife runs from April 4 to May 22 which is International Day of Biodiversity. The goal is to accumulate enough kilometres from participants to stretch across Canada and create national awareness about wildlife conservation and biodiversity. Check out all the details at www.nationalwildlifeweek.com

A school challenge might be to have students, families, etc. accumulate the number of kilometres that a right whale female swims from the Bay of Fundy to calving area off Florida (~2200 kilometres or ~1360 miles) by swimming, paddling, walking, cycling or running (any non-motorized method could be acceptable). Or perhaps a shorter distance for example from Cape Cod spring feeding area to the Bay of Fundy (~470 kilometres or 290 miles), or between the two critical habitats in Canada, the Bay of Fundy and Roseway Basin (~280 kilometres or ~175 miles). Or pick your own important locations for right whales during their yearly movements and calculate that distance. The distances here were calculated using the daftlogic.com google map calculator www.daftlogic.com/projects-google-maps-distance-calculator.htm
