SC67A | Bled, Slovenia

Hues of blues and vibrant greens reflect off the calm, clear waters of Lake Bled, a fairytale of a place located in the upper region of northwestern Slovenia. It is this quaint community of Bled, nestled in the foothills of the Julian Alps and famous for its cream cake, that set the stage for nearly 200 scientists from over 40 countries to present their recommendations for whale management policies at the International Whaling Commission’s Scientific Committee meeting in May.

The Scientific Committee (SC) is the body that advises the International Whaling Commission (IWC) on whale stock management and conservation measures. Pacific Whale Foundation (PWF) Founder, Greg Kaufman is an Invited Participant to the SC and serves on several subcommittees including: Whalewatch, Southern Hemisphere whales, Small Cetaceans, Photo-ID and Non-deliberate Human Induced Mortality on Cetaceans. He also serves as the international whalewatch representative to the IWC’s Conservation Committee. Part of PWF’s presence at the IWC is to help ensure scientifically based management of the world’s whale populations.

PWF has been instrumental in providing a comprehensive assessment of the impacts and value of whalewatching. Greg is a team member for the IWC’s Modeling and Assessment of the Whalewatch Industry (MAWI) that will undertake a workshop in the next six months to define a long-term assessment on global whalewatch operations. Since 2010, Greg has also been involved in drafting an international Strategic Plan for Whalewatching. This plan is undergoing further review with an expected international roll-out in the next few years.

A dozen papers authored, co-authored, or using PWF data were presented to the SC this year. One of the most highly regarded papers was focused on photo-identification of Bryde’s whales in Latin America. This work, long thought to be near impossible to conduct, was co-led by PWF Ecuador researcher, Cristina Castro who collected and compiled the data. Barbara Galletti also presented research funded by PWF on Chilean blue whales, focusing on a small population found off the coast of Chiloe Island.

FACT OF THE WEEK: Whales play a crucial role in the carbon cycle

MORE ON THIS: In a previous Fact of the Week, we learned how plankton helps the oceans ‘biological pump’, a process that supports the global carbon cycle by removing carbon from the air and storing it in the deep sea. This week, we’re going to talk about the largest living creatures in the ocean, whales, and their role in the carbon cycle. Their movements, deaths, and even feces all contribute to the ‘whale pump’ which works with the biological pump to promote carbon storage.

 

Movement: When whales swim from deep waters to the surface, they move nutrients up with them. Bringing nutrients to the surface increases the food source for phytoplankton, which play the first part in carbon uptake.

Plastic Free Life

Five practical tips to reduce plastic, starting today.

Re-use glass jars. There are a ton of prepared foods you can purchase in glass jars; think pasta sauce, peanut butter, salsa, pickles and so on. Instead of buying plastic containers, re-use your jars for leftovers, packed lunches or keep them for storing your dry goods. Which brings us to the next tip…

Buy in bulk. Many stores provide items such as grains, pasta, legumes, nuts and cereals for you to buy unpackaged. Simply bring your jars and measure out what you need. You’ll save money as well as the planet. Remember to check with customer service before you begin, as each store has a particular method for measuring weights. Hint: cotton bags are another great option when buying unpackaged items, and often have their weight printed on the tag (making it easy to deduct at the checkout).

Sea Turtles of Isla De La Plata

Sea turtles are one of the main attractions of the Isla De La Plata tour. Hundreds of tourists look forward to arriving at Drake Bay to watch turtles gather around the boat giving them one of the most amazing spectacles of their lives. Some rush to submerge their GoPros in the water in hope of catching an underwater glimpse of this ancient creature of the sea, while others prefer to take pictures them from the top of the vessel to get a wider perspective.

However, it was not always like this. Only 5 years ago, sea turtles were rarely seen at Drake Bay, Isla De La Plata. So what was caused this increase in sea turtle numbers in such a short time?

For year, captains from Isla De La Plata vessels would rush straight to the island and barely slow down until they reached Drake Bay. If they were asked by tourists or guides to slow down because of potential collisions with sea turtles, they would respond with “sorry, we need to arrive as soon as possible”. Captains did not much care about the sea turtles, as they were not tourist attractions and slowing down was considered a waste of their time. Luckily for the turtles, this was about to change in a drastic way.

Machalilla National Park hired a new manager, who ordered the park rangers to be alert of speeding vessels near Isla De La Plata and to enforce speed limits that had long been in place. The fining of a single vessel is all it took to begin to see a change in vessels navigating these waters.

Celebrate Endangered Species Day

Endangered Species Day is a celebration of the nation’s wildlife and wild places and is an opportunity for people of all ages to learn about the importance of protecting endangered species. Started in 2006 by the United States Congress, Endangered Species Day occurs on the 3rd Friday of May to inspire people to take action in their everyday lives to help protect endangered species.

At Pacific Whale Foundation we research two endangered species: humpback whales and false killer whales.

As with many endangered species, both humpback whales and false killer whales are endangered due to human activities. The North Pacific population of humpback whales was hunted until only a few hundred individuals remained. Although their population has recovered immensely—recent estimates suggest approximately 20,000 humpbacks in the North Pacific—they and other large whale species are still at risk of vessel collisions and entanglement in fishing gear. Our current research on humpback whales aims to reduce the risk of these collisions by determining which factors contribute to detectability of the whales.

Top 10 Ways To Celebrate Earth Day

In honor of Earth Day, we wanted to share 10 ways to engage with Mother Nature. You probably already recycle, so here are ten alternative ways to help the planet:

10. Participate in a citizen science project to help marine life.

  • Whale & Dolphin Tracker is a mobile web-application to report sightings of whales and dolphins so scientists can learn more about their patterns. You can log sightings in real-time and view them on a map or review profiles later. Visit log.pacificwhale.org to register with your smartphone.
  • Match My Whale is a web-based app to help researchers photo identify humpback whales by their flukes. Learn more and join today at www.matchmywhale.org
