What is the fastest marine mammal?

The 2012 Summer Olympics are less than 10 days away and with this comes lots of intense swimming competitions (among other events). This got me wondering, if I lined up various species of marine mammals which one would be taking home the gold? Check out the average top speeds of 10 species in the graph below. (Now time to get the image of an orca wearing a Speedo out of my mind.)

Running Advice for Overweight Runners

Get active, stay safe, and build your fitness over time

Man and woman running outside

Runners, despite what may be advertised, come in all shapes and sizes. If you’re overweight, running is a great option that can help you improve your health, get in shape, boost your confidence, and achieve a healthy weight.

That said, getting started with running may be a bit more challenging if you are overweight due to the fact that extra body fat can make you get winded more easily than those who are leaner.1

Try not to get discouraged by this and see it as just one hurdle to overcome in a journey toward better health. Here’s some advice on how overweight runners can safely start a healthy running habit and reap all the great benefits of running.

How to Start Running When You’re Overweight

Set yourself up for success by making sure that you are medically cleared to start running and that you have the proper shoes to support your body once you begin.

  • Check with your doctor
  • Get proper footwear
  • Start small
  • Switch to run/walks
  • Add strength training
  • Believe in yourself

Check With Your Doctor

This is an important step for anyone who’s new to running, but especially if you’re overweight. Share your running plan and goals with your doctor, and have him/her assess your plan and any potential health issues. Talk about any pre-existing conditions or previous injuries that might have an impact on being able to start a regular running program. Visit timesunion.com.

Your doctor may also recommend that you do an exercise stress test on a treadmill to rule out any cardiovascular issues. If he or she deems it’s not quite safe for you to start now, talk about what milestones you need to reach before you can.

Get the Right Shoes

Wearing the wrong running shoes for your feet and running style can lead to injuries and general discomfort while running. If you’re overweight, the extra weight and pressure on your joints can make you even more vulnerable to injuries, so it’s crucial that you get the right running shoes for you.

Go to a running specialty store, where trained salespeople can do a running gait analysis and recommend the best choices for your running gait, foot, and body type. You may need shoes with extra cushioning, good arch support, or some other special feature.

You should replace your shoes every 300 to 500 miles, although this can vary depending on how you run, your weight, and the type of terrain you cover. Heavier runners typically need to replace their shoes more often.

How to Build Up to Running

Even if you have no plans of eventually running a marathon, remember that your fitness journey is a proverbial one nevertheless.

Start Small

Trying to do too much too soon may lead to injury and burnout. If you’ve been inactive for at least a few months or longer, you should start by walking.

You can begin walking on a treadmill, outside, or even in a pool. Start with just 5 or 10 minutes if that’s all you can manage. Consistency is key, so try to walk a little bit each day. Just get your body used to the activity and work up to a continuous forward motion for 30 minutes before you start to add some running.

Switch to a Run/Walk Strategy

Once you’ve built up your fitness through walking, you can get started with run/walk, which is an excellent strategy to safely and comfortably build your running endurance.

  1. Start your run/walk session by warming up with a 10-minute brisk walk to get your heart rate up and blood flowing to the working muscles.
  2. Next, run easy for 1 minute and then walk for 2 minutes. The walk should be an active rest, not a complete break. Don’t walk casually—do it with a purpose, like a power walk, to make sure you’re getting a good cardio workout.
  3. Repeat this cycle for 15 to 20 minutes, and then finish with a 5-minute walk as a cool down.

As your 1-minute run intervals become easier, you can increase the number of your run intervals and decrease the length of your walk intervals.

While some people try to get to the point where they can run continuously without walk breaks, others decide to stick with run/walk as a long-term strategy, using intervals such as run 3 minutes/walk 1 minute or run 2 minutes/walk 30 seconds.

Taking It to the Next Level

Once you’ve built up your endurance with run/walks, you should continue to challenge yourself by increasing your effort or distance during your runs. This will help boost your calorie-burning efforts, improve your fitness even more, and help prevent you from getting bored with your routine.

You can start adding speed by warming up for a mile and then running at a faster pace (breathing heavy, but still in control) for a minute and then recovering at an easy pace for a minute. Continue with this pattern for two miles, then cool down for 5 to 10 minutes.

When that gets too easy, you could always increase the time of your speed intervals or do hill repeats instead.

Add Some Strength Training

If you’re not already doing some strength training, try to incorporate at least one or two sessions in your weekly routine. Not only will you burn more calories while you’re doing these exercises, but your increased lean muscle mass will improve your running performance.2 You’ll be able to run faster and longer, and pump up your calorie burn when running.

Strength training also helps prevent running injuries, so you’ll be able to maintain your commitment to exercise by staying injury-free. You don’t need to belong to a gym or have special equipment to strength train.

Ways to Stay Motivated

Sticking with your running plan and achieving your goals may, at times, feel difficult. Do what works best for you when it comes to keeping your motivation up.

That might include strategies such as:

  • Rewarding yourself
  • Running with a buddy
  • Setting specific goals3
  • Tracking your progress3

Ignore the Naysayers

Unfortunately, there are people everywhere who can take issue with just about anything, which may make you feel self-conscious.

While you may not have the speed or distance of other runners (yet), those who enjoy the sport tend to appreciate anyone else who does too. And if you’re worried about what non-runners think, just remind yourself of how hard you’re working and that they’re missing out on all the benefits of running that you’re reaping.

What they’re into … with Jim Wharton (Seattle Aquarium)

This is a series I’ve been featuring each Tuesday this summer to get a special sneak peek at the different personalities behind the scientists, activists, and educators (including bloggers) who play an integral role in the marine science conservation field. It’s essentially an extension of the overwhelmingly popular and well done Tumblr blog, This Is What A Scientist Looks Like, (BCS was featured in April!) which sets out to illustrate that scientists are not just crazy haired nerds in lab coats. I’ve sent a list of 15 random questions to some folks I know and asked that each person share at least their answers to 5 of them. This week’s feature shares some insight into the world of Jim Wharton.

Jim Wharton, Director of Conservation and Education at the Seattle Aquarium, feels at  home again in the Pacific Northwest after over 8 years in Florida working for the Smithsonian Marine Station and Mote Marine Laboratory. He started his career in marine science education as a volunteer, then educator at the Oregon Coast Aquarium. Jim is also deeply involved with the National Marine Educators Association (NMEA) where he is a member of the board of directors and more committees than he has time for. You can learn more about him at about.me/jimwharton or follow his on Twitter for marine science miscellanea @jimwharton.

Jim notes, “The mission of the Seattle Aquarium is ‘Inspiring conservation of our marine environment’. To be true stewards of the marine environment people have to be science-literate and ocean-literate…but first they have to care. Marine science education helps people develop all these muscles, for flexing in support of the ocean.”

What is the last thing you bought that you shouldn’t have?
Unagi. I know freshwater eel is on SeafoodWatch’s sushi red list, but sometimes I’m weak. A colleague explained to me recently that one of the precursors to behavior change is a public declaration…so consider this mine. Any animal that swims thousands of miles out to sea to reproduce deserves a little more respect from me.

What is your favorite sundae topping?
Dark chocolate and caramel combo…on principles of general awesomeness.

What three things would you take with you to an island?
Assuming my family and/or a satellite phone is cheating…The Demon-Haunted World, mask/fin/snorkel, sunglasses. The Demon-Haunted World, by Carl Sagan, is a treatise of reason and a book I can read over and over. Mask/fins/snorkel, well, it’s an island. And anyone who knows me knows that I would be very uncomfortable without my sunglasses.

How superstitious are you?
Not at all (see above). I used to pretend to be superstitious (probably because everyone around me seemed to be), but I’ve given up believing that jinxes, broken mirrors, or wearing the same socks on gamedays have any real effect on the external world. I do think the idea of finding some locus of control in a chaotic world is a very human and understandable impulse. Wait, did I just call myself ‘inhuman?’

What is your favorite day of the week?
I’ve often bragged that Fridays and Mondays are meaningless to me. It’s a fringe benefit of loving the work you do. 

If you were a geometric shape, what would you like to be?
A star? Too much? I guess I’ll go with a triangle. Triangles are well-balanced and they have a point. I just hope people don’t find me obtuse.

What’s some other random favorite information about you?
I actually enjoy public speaking, but hate making toasts. Go figure.

Thank you for participating, Jim, keep up the great work! Everyone else, don’t forget to check out previous editions of “What they’re into …” with David Helvarg and Miriam Goldstein.

No balloons at the celebration for the Beach Chair Scientist …

Today is the fourth birthday of the Beach Chair Scientist blog. Despite the fact that some companies label latex balloons as ‘biodegradable’ and therefore, ‘safe’ for the environment, I will not be decorating any birthday celebration with balloons. Balloons blow! What has been widely spread is that latex balloons breakdown at ‘the same rate as an oak leaf from a tree‘. First, let me explain ‘latex’. Latex is a white tree sap of rubber particles from the plant, Hevae brasiliensis. After it is processed it becomes rubber. Rubber, as we know, is used in a variety of products because of its strong resilience and tear resistance. Balloons are made from latex (essentially, liquid rubber) once colors are added.

It just would not feel like a celebration for Beach Chair Scientist because I have been to countless beach clean-ups and see those latex and mylar balloons, as well as the strings that are tied to them, along the shoreline. Balloons are just not following the path that balloon manufacturers want us to believe. It may be true that research done in a controlled setting proves that when latex balloons rises to almost 30,000 feet they will freeze and bust into tiny slivers that fall back to earth. However, there are just too many natural factors (e.g., trees, wind) that impede balloons from rising to that height prior to losing their helium and flaying to the earth whole. Not to mention that even if latex balloons do break apart into tiny shards the tiny shard are still detrimental to the ocean. According to Sea Turtle Foundation, “Most balloons are made from ‘biodegradable’ latex, which degrades on exposure to air. However degradation can take up to six months and balloons floating in seawater can take up to twelve months to degrade”. In many areas it is illegal for mass balloon releases. Please check out your area for the local laws on balloons.

Here are ten examples of balloons affecting the ocean ecosystem:  

  1. On a New Jersey beach a sperm whale was found dying because it had a balloon in its stomach halting the passage of food.
  2. At a clean-up was on an island 5 miles out to sea – the distance cleaned at the 4 sites we targeted was about 1/2 mile of shoreline – in southern Maine this past June over 550 pounds of marine debris were found, including 232 pieces of debris (9 of which were balloons and one was found right next to a gull’s nest).
  3. Birds will collect plastic debris for their nests, and unknowingly construct death traps for their young.
  4. Balloons, plastic straws, plastic bottles, plastic bags, and metal beverage cans were found to be the most abundant type of marine debris litter as a 10-year national survey completed in 2008.
  5. Most of the trash found along the California coast during a 2003-2010 survey was 82% land-based plastics, including plastic bags, plastic bottles, balloons and straws.
  6. Fishing gear fragments, packaging materials, balloons, bottle caps, and straws were found to be the most common items found during a Cape Cod survey that collected 5,829 items along one-kilometer.
  7. A leatherback turtle starved to death because a latex balloon was stuck in its stomach. After the turtle necropsy, the only thing found in its intestines was three feet of nylon string attached to a balloon.
  8. Animals can become entangled in balloon ribbons and string, restricting their movement and their ability to feed.
  9. Bottlenose dolphins in California, loggerhead turtles in Texas, and a green turtle in Florida were all found dead after ingesting latex balloons.
  10. In the UK, Risso’s dolphins in French waters and fulmars in the North Sea are known to ingest balloons.

If you’re still keen on celebrating with balloons try to do activities where you can control them and not have them released into the atmosphere. You can put prizes inside them or decorate them or play games. Below are are alternatives for decorating and commemorating without balloons. Check out the background image from Orlando Sentinel with the juvenile loggerhead turtle swimming close to the floating balloons.

One last thing, if you’re in the DC area Saturday, July 21st and would like to join me during a stream clean-up with United By Blue please feel free to come along! It’s a great event co-sponsored by Subaru and fun for the whole family. Read this article about my first experience volunteering with them. Please feel free to drop me a line at info@beachchairscientist.com or leave a comment below if you have anything else you like to add to this post or just a question in general.

Colorful coquina clams sign of healthy beach

Those tiny, colorful clams with two siphons poking our of their shells that emerge quickly once the waves wash gently ashore are known as coquina (ko-KEE-nah) clams. These bivalves rarely exceed an inch long and are indicators of a healthy beach. If eroding beaches are constantly being renourished, coquina clams, as well as other sand dwelling invertebrates (i.e., mole crabs), could become buried under the extra sediment. Many beaches have to be renourished because the natural supply of sand from rivers and other sources from the mountains have been impeded by dams and reservoirs. Coquina clams can usually recover their populations if a beach has not been renourished in a year or two.

They tend to feast upon single-celled detritus or algae. Fish, shorebirds, and humans tend to feast upon them. That’s right, coquina clams are found around the world and are enjoyed steamed with butter or even as ‘the basis for a great potato puree‘. In Australia there is a commercial fishery for the meat (God help those processors).

In Florida, you can visit one of my favorite places, Blowing Rocks Preserve, and see the coquina rock outcrop. The coquina rock is a soft rock that is made up of the coquina clam shells (as well as other materials). But, what makes this rock outcrop so unique is that it is part of the largest section rock, known as the Anastasia Formation, from the Pleistocene epoch (2.576 million years ago).

Caring for Your Older Pet

image of a dog and cat.

Many of the same problems that affect people as they age, such as arthritis and diabetes, can also affect your pet. Making a few changes to the way you care for your furry friend will help you ensure that your pet stays healthy and happy as the years go by.

Look for Common Signs of Illness

Changes in your pet’s behavior can be a sign that something is wrong. Sick animals can become more or less affectionate than before. Some may refuse to leave your side, while others will spend more time alone. Cats, in particular, tend to find out-of-the-way hiding places when they don’t feel well.

If you notice any of these symptoms, it’s a good idea to make an appointment with your pet’s veterinarian:

  • Changes in Eating Habits. Has your pet lost interest in eating or started drinking more than usual? A lack of interest in food can be caused due to dental issues, kidney or liver disease or a change in food, while increased thirst can be a sign of diabetes. Learn more about Pet Friendly Box Dog Multivitamin.
  • Elimination Woes. Frequent constipation or diarrhea or difficulty urinating can be signs of serious illness and should not be ignored. Housetraining setbacks can also occur as your pet ages. Sometimes, making a few modifications, such as adding litter boxes to every floor of your house for your arthritic cat or adding a ramp to your home for a dog with hip dysplasia can solve the problem.
  • Bumps, Lumps and Other Issues. Bumps and lumps can be caused by harmless cysts or may be a sign of cancer. The only way to determine the cause is with a visit to your veterinarian. Other issues that warrant a trip to the vet include frequent coughing, trouble breathing, vomiting or changes in your pet’s coat.

Nutrition for Senior Pets

Good nutrition is essential to keeping your older pet healthy. Keep these tips in mind when selecting pet food.

  • Buy Senior Pet Food. Help your pet maintain a healthy weight by feeding food specially formulated to meet the nutritional needs of older pets. Excess weight stresses the joints. If your pet already has arthritis, gaining weight will make symptoms worse.
  • Avoid Overfeeding Your Pet. Older pets generally need less calories because they are less active. Adjust the amount of food you give your pet to avoid weight gain. Pay attention to the calorie count of treats, too. Buy low-calorie treats and limit the amount of treats you offer your pet.
  • Get Rid of Free Radicals. Free radicals, unstable molecules that can contribute to aging and hamper immune system functioning, can be neutralized with foods that are high in vitamin E and beta-carotene.
  • Choose High-Protein Foods. Although your dog may need fewer calories to maintain an ideal body weight, he or she still needs a diet high in protein. Protein is essential for maintaining muscle mass. Some cats have trouble digesting protein as they age. Before you buy a high-protein food for your cat, check with your veterinarian.

Make Your Pet Comfortable

Older pets will appreciate anything you can do to increase their comfort, starting with a soft place to rest. Look for cat and dog beds made of therapeutic foam that support your furry friend’s joints. Heated beds will help your pet keep warm during the winter months.

Staying warm is a particular concern for older pets. Pets that were perfectly comfortable on chilly days in their younger years may have trouble staying warm when temperatures drop. A pet jacket or sweater will help keep your senior pet warm, although dogs may be more likely to tolerate wearing a sweater than cats.

Daily runs with your dog may have to end if arthritis or a general slowing down due to age is a problem. Although runs may no longer be possible, it’s still important to make sure your dog still gets exercise every day. Playing games with your dog or cat not only improves physical fitness, but also helps keep your pet mentally sharp.

Arthritis and other joint problems can make jumping more difficult. If your pet usually sleeps with you but has trouble jumping on the bed, buy pet stairs or a ramp to make getting into bed easier.

Regular veterinary visits are very important as your pet ages. If it’s been six months or more since we have seen your furry friend, give us a call to schedule an appointment.

A naturalist’s must-see destination: Chincoteague National Wildlife Refuge

I have it on my bucket list to explore at least ten more National Parks in the next decade, but I am going to have to rely on family and friends to share their adventures since I just spent some time in Maine visiting Acadia National Park. My brother, wife, and their sons (8 and 6 years old) just spent a week at Chincoteague National Wildlife Refuge and have kindly taken the time to share their adventures from the boys perspective. Take a look at this 60-second  movie on what sort of wildlife awaits you at Chincoteague National Wildlife Refuge. Also, here are 5 little known facts about Chincoteague National Wildlife Refuge to hopefully entice you to visit. (The interminable forests should become graceful parks, for use and delight. — Ralph Waldo Emerson, 1844)

  1. Chincoteague National Wildlife Refuge was purchased with Duck Stamp revenues.
  2. Most historians believe that the famous Chincoteague ponies are remnants from that settlers who used the island for grazing livestock in the 1600’s in an effort to avoid difficult fencing regulation. Descendants of those ponies are still living there today.
  3. In a CNN Special from June 2012, Assateague Island National Seashore was named as one of the 7 prime spots to view wildlife. Chincoteague National Wildlife Refuge is at the Virginia end of the National Seashore.
  4. The endangered sea beach amaranth is well adapted to survive the harsh seashore conditions of Chincoteague National Wildlife Refuge.
  5. Chincoteague National Wildlife Refuge has 14 ‘pools’ that total over 2,600 acres that are carefully manipulated to control moisture levels.

Witness the horseshoe crab molting process

I’d like to share this remarkable two and a half-minute video of a horseshoe crab during the molting process. Produced by the Hong Kong Coast Watch and filmed by Kevin Laurie in May 2011, this film shows a juvenile Tachypleus tridentatus (one of the three species found in the Pacific ocean along the coast of Japan) shedding its outgrown exoskeleton at 16 times real speed. With calming music playing in the background you can witness the horseshoe crab as it burrows in the sand and exerts a tremendous amount of effort pulsing and pushing as it releases itself from its old shell. You can also get a glimpse as to the interesting creatures crawling around on the shores of the Pacific sea. For more information on the morphology differences between the four extant species of horseshoe crabs visit the Ecological Research & Development Group (ERDG), a leading resource for all things horseshoe crab related.

Don’t underestimate the utilities of algae

A reader recently asked where to find a field guide to seaweed of the northeast Atlantic and also wanted to know in particular “which species is edible, how to prepare it and what historical uses were of specific seaweeds”. I am going to do my best in answering and encourage you all to continually challenge me with questions. Please feel free to comment anywhere or simply email info@beachchairscientist.com.

It seems as though the most thorough resource with the most concise information online for Atlantic  coast species would be from the Field Guide to Algae from Acadia National Park. A much more extensive online reference would be the AlgaeBase (The World of Algae was absorbed into this database) produced be the Irish Seaweed Research Group. And, of course, there seems to be a gaggle of print books out there as well which are always nice to have while beachcombing.

For the second part of the question I am going to take the time to elaborate on my previous post about edible seaweeds found in ice cream. Here are 10 utilities for algae that you may or may not know about. There are plenty more but I have to leave a little something for you to research with the resources I found (also there is a collection of recent news article below).

  1. In general many seaweeds can be used as your garden’s best friend. Check out this great article from Earth Easy on How to Use Seaweed to Mulch Your Garden.
  2. Algae can be used to make a biodiesel.
  3. Blue-green algae are used as a dietary protein, as well as in aiding weight loss, stress, fatigue, anxiety, depression, among many other others issues (check out the image of the gentleman drinking some below – yum?).
  4. Dulse (Rhodymenia palmata) is a favorite food of those living in Canada, the UK, and northern Europe.
  5. Irish moss (Chondrus crispus) is a food addictive and is the source of carrageenen which thickens and stabilizes foods, including ice cream and beer.
  6. Laminaria seaweeds (also known as Saccharina seaweeds) are thought to stimulate cleansing, reduces water retention, and tone thyroid action.
  7. Nori (Porphyra) is popular in Japanese cuisine and is known for its high nutrient value.
  8. Sargassum seaweeds are thought to disperse accumulated phlegm and water.
  9. Sea lettuces (Ulva) are enjoyed raw in salads and cooked in soups in Scandinavia, the UK, China, and Japan.
  10. Toothed wrack (Fucus serratus) is used as a bath soak in Ireland and is thought to help with arthritis.

If you or anyone you know swears by drinking algae as a supplement please share your experience below. I’d love to read your perspective!

From sea to shining sea, a flag for you and me!

I hope everyone enjoys a happy and safe Independence Day this 4th of July!

(Please be careful using fireworks. According to Mother Earth News, “Fireworks can unleash a shower of toxins into soil and water, and scientists are only beginning to figure out what that means for human health”. Also, don’t forget your boat safety skills. Instead, get creative for our new contest this summer!)
