10 tips for a successful beachcombing trip

Pick up that clump! You never know what you'll find.

Pick up that clump! You never know what you’ll find.

It’s my favorite time of year. This is the best time to explore the beach. It’s still sunny and warm, there are frequent storms (you’ll see why that matters later), and there are few people on the beach. For another six weeks along the mid-Atlantic (before it gets too cold), I encourage you to spend some time getting to know your local shoreline. Here are 10 tips for a successful beachcombing trip.

10. What to bring. Here is a list of some items you may want to remember so you’re prepared for any situation.

  • Often the beach is considerably cooler than inland so bring layers. You may want to wear hiking pants and bring a zippered sweatshirt so you’re equipped with lots of pockets for some other items that might be essential.
  • Make sure to have some appropriate soles. Sure it’s our instinct to be barefoot, however if you want to venture out along the jetties or rocks make sure you have some old sneakers or those water shoes with some decent grip (After all, you don’t want to ruin your adventure with a puncture to some sharp object). Also, the water might be a little cooler than you’d prefer and some good foot cover will allow you to wade into a tide pool, since pools are really popular now a days, you can find more swimming pools for sale here for your home as well.
  • Make sure to have a watch.
  • Even during the off-season the sun is shining and is strong enough to give you a burn. Make sure to bring along a hat, sunglasses, and sunscreen.
  • It’s always a good idea to bring a shovel, grabber sick, or even a metal detector so you can gently investigate inside crevices and below the sand.
  • You are going to want to cherish the moments so find that camera and try to make a neck strap so it’s always handy. You can take pictures of items you find and want to learn about later. You’ll also want to catalog those smiles in the sun.
  • Take along a small (i.e., not heavy) identification book so you can learn more about what you find while on your outing.

9. Be hands free. One more item that you’re going to love me for suggesting is a backpack. This way you can investigate a little bit further from your base and your items are quickly at your disposal.

8. Leave important items behind. Don’t ruin the day by losing a credit card or your phone. If you’re active and in the moment you might lose something and it’s going to be difficult to retrace your steps. I won’t say “I told you so”. On the same note it’s important to leave animals, plants, rocks, and seashells where you find them. If you want to have a little bit of the beach in your home check out these great books by Josie Iselin.

7. When to go. To get the optimum experience for beachcombing you’ll want to check on when low tide is at your beach spot. The best time to go beachcombing is 2-3 hours prior to low tide or an hour or so after (This is why a watch is important, you don’t want to get stuck on  shoal during high tide). Many intertidal animals live under the water in the sand during high tide, but come out to play (and seek out food) during low tide. If you can time it so you get to check out the beach after a big storm you’ll be in for a real treat. The strong wind and wave action of storms will wash up a fossils, bones, seaweed, and lot of other interesting treasures from the ocean floor. Also, keep in mind that dawn and dusk are difficult times to identify beach treasures. Although this is a great time to spot birds as many fish tend to come up to the surface at these times.

6. Where to go. My favorite spot to beachcomb is the Stone Harbor Point in NJ, but it’s not always easy for me to get there these days. I like to remind myself from time to time that I don’t need an ocean to beachcomb. There is a lake and creek in my neighborhood and these spots are a great place to spend the afternoon. After all, these waterways eventually lead to the ocean.  No matter where I decide to spend some time beachcombing I always make sure to note the general water quality.

5. Be careful. This is just a reminder to not tamper with obviously dangerous items. Fish hooks, metal canisters, and needles often wash up on the beach. While I am going to also suggest doing your part and picking up marine debris it’s also a good idea to err on the side of caution and when poking around. Also, some rocks look very steady but it’s important to be aware of your surroundings. If you are feeling like having an adventurous day it’s might be a good idea to make sure you have someone else with you. One last thing about being careful,even though the dunes might look like an interesting place to check out – it’s important to know that those grasses are incredibly brittle and can crack easily. It’s also against the law to walk on the dunes. The dunes are an important part of the beach ecosystem as they protect our homes from storm surge.

4. Leave it be. Each rock that you turn over is part of an ecosystem. A rock might be an essential part of an animal’s home as it helps pool water during high tide. Rocks also protect them from predator as well as the sun. It’s important to always remember to not take animals out of their natural setting – especially if you see them in a tide pool. Many animals are naturally attached to rocks for survival and you could be risking their survival.

3. Play. You might not want to go home, but you also might be in the company of some people that just don’t have a very long attention span. Even more frustrating is repeating the phrase, “No, you cannot go in the water today” over and over again. Build a sandcastle. Surf fish with your best saltwater spinning reel under 100. Look to the horizon for dolphins or porpoises. Make a sand angel. Look up to the sky for cloud animals. Check out my ebook for other beachcombing adventures.

2. Bag it and track it. It’s always nice to be prepared to be able to do your part. I prefer to take along a hefty canvas bag that can fit in a backpack so I can tote marine debris back to a garbage can. You might even try to acquire one of these nifty bags with holes for sand to percolate through from the Green Bag Lady. When you head back to the car you can even do some citizen science and log your marine debris on the Marine Debris Tracker.

1. Don’t expect too much. It’s important to remember to relax and respect the area you are exploring. All of the ideas above are simply suggestions and ideas to ensure you get the most out of  a beachcombing adventure. Please don’t hesitate to share your favorite stories, spots, and other ideas for a great day. You can comment below of email me at info@beachchairscientist.com.

Getting to know three … Malacostracan edition

Ever know instinctively that some animals are ‘related’ and just can’t pinpoint their similarities? On the third day of every month I explain three features that are common among three animals of a certain group. Of course, generally each group has more than three representatives and even  many more similarities and then even more differences, but I am going to choose three similarities that link threes to keep it simplified. This month is focused on the shrimp, the lobster, and the crab – all crustaceans, but more specifically all are members of the largest of the six classes of crustaceans known as the Malacostraca class. (Need a refresher on the trusty mnemonic device for classification? Click here.)

How to track a horseshoe crab

Today I am excited to bring a new video produced by Coastal Kingdom TV, a television series dedicated to sharing the unique and diverse habitats of the South Carolina lowcountry. Host Tony Mills demonstrates the best way to track horseshoe crabs in the tidal flats of South Carolina and does a superb job enlightening us on some of the animal’s unique characteristics.

Longfin inshore squid pulses to Cypress Hill

No one can deny that cephalopods are smart and elusive creatures, and here is yet another example that proves the point. Scientists at Marine Biological Laboratory in Woods Hole, MA did experiments on the axons of the longfin inshore squid and were excited to see a vibrant color-changing spectrum of the squid’s brown, red, and yellow chromatophores. The chromatophores each have muscles that contract when stimulated revealing the pigment below. Check out this video from Backyard Brains to see the results {Fair warning: wear headphones if you’re in the office!}.

Also, you can check out this video to learn more about the cockroach leg stimulus protocol they used for the experiment.

Holy, mole(y) crab!

Mole crabs are recognizable decapods with their barrel-shaped bodies and a grey colored exoskeleton and known to many of us as ‘sand fleas’. We often only see them for a wee bit when a wave (or curious hand playing in the sand) dislodges them and they quickly scurry back under the sand. These clawless crabs are not biting fleas and are fairly harmless member of the crustacean group.

Let me tell you what makes the mole crab a critter I can get excited chatting up during a day  at the beach. First, is that as the tideline goes in and out during the day, so do the mole crabs. Their preferred home is to be buried under the sand right at the tideline. Also, rather fascinatingly, mole crabs only move backward! They use their back legs to bury themselves under the sand as their head goes later.

They depend on the action of the ocean to filter them loose plankton and organic debris. They grab the particles by keeping their antennae at the sand surface (which is why their head goes in last as they bury themselves). They also use gills to take oxygen out of the water to breather, just like other crustaceans. During the summer you may see a female carrying one with eggs on her underside or near the legs. The orange eggs have just been fertilized while the darker grey eggs are ready to hatch. Male mole crabs are smaller than females, only reaching about half an inch in length, while females are typically an inch long.

Mole crabs are also a very popular form of bait for surf fishermen.  There are ten species recognized throughout the world, but two are most common on the eastern Atlantic and Gulf coasts, Emerita talpoida or Emerita benedicti.

What they’re into … with Braddock Spear (Sustainable Fisheries Partnership)

It’s Tuesday and so I am sure you know by now, but this is a series I have 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. Here you find the weird preferred smells among other things of Braddock Spear from the Sustainable Fisheries Partnership.

Braddock Spear is Deputy Director of the Improvements Division at the Sustainable Fisheries Partnership (SFP) and has worked there for the last 18 months trying to improve fisheries around the globe. For 8 years before SFP, he worked at the Atlantic States Marine Fisheries Commission ending his tenure as Senior Coordinator for Policy and having coordinated fisheries management of horseshoe crabs, northern shrimp, and Atlantic menhaden. Also before joining SFP, Braddock blogged on the sustainable seafood movement at Sustainable Ocean Project. The site is no longer updated with new content, but all past posts are still there for the reading. Braddock received a BS in Marine Biology from the University of Maryland and a MA in Marine Affairs from the University of Rhode Island.

What is the last thing you bought that you shouldn’t have?
A ticket to Vegas. I’ll be saving my pennies til I go.

What is your favorite fruit flavor?
Mango! I was spoiled in Belize when I got fresh mango from my host family’s tree every morning.

What is your favorite Sunday breakfast?
A coffee and a scone at the Baltimore farmers market.

What is your favorite scent?
Gasoline and cigar smoke are two of my favorites. Though not too much of either and definitely not together.

How superstitious are you?
Not at all. I’ve walked under lots of ladders, broken a few mirrors, and had a black cat. Despite all that, I’d say my luck has been pretty good (hoping that continues in Vegas).

Bonus random fact:
I’ve recently become a big fan of street art. If you’re interested, check out: http://www.streetartnews.net/

Thank you for participating, Braddock! It was great to hear from you (Braddock is an old co-worker on mine). Have a great time in Vegas!

Getting to know three … Echinoderm edition

Sure you know that some animals are related to one another. Often though it’s difficult to pinpoint their similarities.  Well, on the third day of every month I am going to explain three features that are common among the animals of a certain group. Each group generally has more than three representatives, but I am going to choose three to keep it simplified.

To get us started … Have you ever thought about what a sea urchin, sea star, and a sand dollar have in common? Among others in this group those three animals are in a phylum of marine animals know as the echinoderms. Sea cucumbers and brittle stars are also well-known echinoderms. Check out the image below to learn what these animals all have in common.

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. Read the latest multivitamin for children by PatchMD reviews.

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.

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.

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).

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.
