13 apps for your day at the beach

August 17, 2011 by 2 Comments

It’s time to get the most out of that last trip to the beach!

Whether you’re ready for a day out on the boat, lounging, beachcombing, catching some waves, or preparing a feast there is an app to get you more involved in your marine environment. Apps are not only a great way to learn something new on the fly but can be a useful tool for engaging one another in settings where you may not have common ground. (OK, at the very least apps settle many ‘discussions’.)

Here is a list of useful and rather attractive apps that can connect you to your inner marine biologist.

AUDUBON FIELD GUIDES: Audubon Fishes of the Caribbean and the Gulf of Mexico and Audubon Fishes – A Guide to North American Fishes include photos, geographic ranges, and concise yet detailed descriptions of appearances. Coming soon is the field guide for the Mid-Atlantic shoreline. ($9.99)

OCEANOGRAPHY STUDY GUIDE: If you are into fun oceanography trivia and want to learn more about the geography of the sea than download this app. It isn’t an endless list of “did you know?” facts but rather a large range of topics with well written articles for the serious beach chair scientist. ($4.99)

OFFICIAL APP OF ISSF: The International Seafood Sustainability Foundation (ISSF) was founded in 2008 when leaders of industry, scientists and environmental champions voiced concern over the future of tuna fisheries. This app provides a glossary of terms, videos, and a list of the status of stocks. (Free)

SEA TURTLE APP: This app was created by the Sea Turtle Conservancy and allows you to follow read the latest on sea turtle news but much more exciting you can track the global migration of different sea turtles with interactive satellite tracking maps! (Free)

Enough sitting around – it’s time to get out there and do something:

MOBILE APP FOR IGFA: The International Game Fishing Association created an app for weigh station locations, angler rules and regulations, customizable quests, and advice for trip planning. What more does a sport fisherman need?

MARINE DEBRIS TRACKER APP: This collaboration is brought to you by the Southeast Atlantic Marine Debris Initiative. The reporting of where you find marine debris can help to focus and prioritize federal efforts. The app uses GPS and allows you minimal work of sorting through lists of common marine debris. (Free)

CRAB APP: This app is an offshoot from the marine wild lab and allows you to collect horseshoe crab species data that will be used in scientific research. Horseshoe crabs are of enormous importance to 1) the drug industry due to their blood, 2) to fisheries for bait, and 3) to migratory shorebirds for its eggs.  (Free)

TIDE GRAPH: I found out that there are many, many apps out there to help you monitor the tides. Tide Graph will work for both coasts in the US and provides graphs to help you see how the tide changes over the day and the month. ($1.99)

If you are preparing a feast or gorging on some dockside seafood:

SEAFOOD WATCH: For years the Monterey Bay Aquarium has produced adorable pocket-sized regional cheat sheets so you can get a quick overview of what species are considered over fished or not in your neck of the woods. They continue to produce this application for your iPhone and use GPS tracking to discover where you are so you can get the most relevant information. (Free)

PROJECT FISHMAP: Monterey Bay Aquarium also gets you more involved by asking you to submit information when you find a restaurant or market that advocates sustainable seafood. As the map grows you can see what spots you’ve not uncovered in your neighborhood. (Free)

FISHPHONE APP: With one quick text (example: “fish salmon”) to 30644 Blue Ocean Institute will fed you intel on your species of choice. For instance, they’ll rank the sustainability and toxicity levels and send an overview of its conservation status. (Free)

SAFE SEAFOOD: This app takes information from ten different seafood rankings (including Monterey Bay Aquarium and the Environmental Defense Fund) to create its list. The app outlines choices in an easy to review “best to worst” list. I particularly like that fish with multiple different market names are listed by each of common name too. ($0.99, but 10% of the proceeds go to EDF)

I am certain I missed many wonderful apps. Please do not hesitate to email at info@beachchairscientist.com to share!

Added October 27, 2011: An app for water quality and to get the most up-to-date grade for your beach presented by Heal the Bay in California.

Where is the coral triangle?

August 16, 2011 by Leave a Comment

After some research I scored a wonderful description of where the world’s most ecologically diverse  marine ecosystem lies. Spanning over six countries this 6 million kilometers squared coral triangle is significant because it is home to six of the seven species of sea turtles. This infographic, produced by World Wildlife Fund, gives a rundown of the protection status of each the sea turtle species as well as a wealth of other great information. For instance, did you know …

… 3000 leatherback sea turtles nested along the coast of Terengganu, Malaysia in 1960? In 2000, according to data from Dr. Chen Eng Heng with the Department of Fisheries in Malaysia, there were none.

… 90% of sea turtle hatchlings never make it to their first birthday.

Take a closer look at the infographic to learn more. Lastly, don’t forget May 23rd is International Turtle Day!

Who are the deepest divers in the sea?

June 22, 2011 by Leave a Comment

After gathering data from marinebio.net, the University of California – San Diego, National Science Foundation, Softpedia, and Scientific American the folks from LiveScience.com have presented this amazing graphic of the 8 deepest divers in the sea. As a bonus, it explains how penguins manage to pull off diving to a depth greater than the height of the Empire State Building! (P.S. If anyone knows where I can find a mentor who can teach me how to create these beautiful infographics please let me know.)

8. Emperor penguin – 1,500 feet deep

7. Weddell seal – 1,970 feet deep

6. Blaineville beaked whale – 4,100 feet deep

5. Leatherback sea turtle – 4,200 feet deep

4. Elephant seal – 5,000 feet deep

3. Southern elephant seal – 5,300 feet deep

2. Cuvier’s beaked whale – 6,200 feet deep

Who has the longest commute in the sea?

May 9, 2011 by Leave a Comment

An animal lives to eat and breed. In order to do this, some animals that call the ocean habitat ‘home’ have to travel great distances to find food or reach a particular breeding ground. Here is a breakdown of some of the most impressive migrations in and around the sea.

Perhaps the longest migration of any mammal on Earth, the gray whales travel 12,000 miles round trip. They spend the summer months in the Bering Sea area between Alaska and Russia. Eventually they make their way to the west coast of Canada and the United States and finally end up in the quiet lagoons of Baja California during the winter months. In the spring they make their way back to the Bering Sea. Also, notable is the migration of the humpback whales. They can travel up to 5,000 miles.

Arctic terns fly over 25,000 miles to the Southern Ocean. Sooty shearwaters travel 64,000 miles over the Pacific Ocean in figure eight patterns.

Leatherback sea turtles travel over 3,000 miles to get to their nesting beaches.

Here is a video from PBS’ Jean-Michel Cousteau Ocean Adventure that gives a nice overview of the migration of the gray whale.

Anglea Kinsey does a wonderful job of being compassionate to the feline population as she plays the role of Angela Martin on the show ‘The Office’. But did you know she also demonstrates equal sympathy for the plight of sea turtles as a spokesperson for Oceana?

Back in December, Angela Kinsey and Racheal Harris (The Hangover) joined up with Oceana for a campaign to get “Sea Turtles Off the Hook!” It is a focused on asking folks to reassess commonly used fishing gear because they may be harmful to sea turtles. She gently reminds us all to “Cut down on your use of plastic shopping bags because many end up in the ocean. If you’re at a beach where there are sea turtles, just let them be. And don’t throw trash out on the street near coastlines. Pick it up!”

What is bycatch?

January 1, 2011 by Leave a Comment

Bycatch is a term used to classify the incidental fish, mammals, birds, sea turtles or invertebrates that may be caught while targeting other species in a fishery. One of the biggest victims of these unintentional catches are the black-footed albatross. They frequently swallow bait attached to the lines of long-line fishing boats. At least 300,000 sea birds are killed by long line fishing each year.

How did the loggerhead sea turtle get its name?

August 16, 2010 by 3 Comments

The loggerhead sea turtle, Caretta caretta, was given the common name because it has such a massive head.  On this massive head is an incredibly powerful jaw that aids the turtle in consuming any type of food it can get its mouth on. This can include corals, sponges, crabs, jellies, fish, other sea turtles,  sea urchins, and even octopi. They are true omnivores. This jaw is the most powerful jaw of all the sea turtles. Out of all the turtles in the world it has the second most powerful jaw coming in behind the Alligator snapping turtle.

Understand marine debris ASAP

August 13, 2010 by 2 Comments

Oh no! It is that moment when I am finally relaxed and settled into my chair at the edge of the water and I look up from my book to see a plastic wrapper whizzing into the sea. I take a look around and do not see anyone running to grab it so I get up and run for the trash. Now don’t get me wrong, I understand that trash falls out of our hands from time to time. That is why I am one of those people that tend to make the extra effort to do the right thing and pick up after someone else, I hope someone would do the same for me. Basically, I have an active imagination. I see the future of this plastic bag as having a relaxing trip to the open sea where it floats on the bright and sunny surface only to be mistaken for a nutritious and delicious jelly by a leatherback sea turtle. Only it gets lodged in the turtle’s throat. It turns out to potentially suffocate the animal and may lead to his eventual death. Yes, that is where my imagination takes me … Unfortunately it is all too much a reality. Watch this clip of an Ecuadorean team of scientists trying to save this green sea turtle who was too weak to survive since his gut was full of plastic.

This plastic bag and other man made trash items that sea creatures commonly mistake for food are collectively known as marine debris. Items may include plastic bags, cigarette butts, fishing gear, bottles, cans, caps, lids, you name it … it is marine debris. The marine debris doesn’t just come from pieces that fly out of our hands while at the beach. The trash that ends up in our ocean can come from drains and sewers on our street. The ocean is the largest body of water and a part of the world wide watershed.

One of the most alarming illustrations of how much marine debris has ended up in our ocean ecosystem is the presence of the Pacific Garbage Patch. In the northern Pacific Ocean (in between Hawaii and San Francisco) there is an island of marine debris larger than the size of Texas that is held together by a centrifugal force of the ocean current known as the North Pacific Gyre. You cannot see this patch from a satellite image because it is simply suspended particles of shoes, toys, plastics bags, wrappers, tooth brushes and many bottles.

Marine debris is everywhere and is quite a nuisance for life in the oceans. In the summer when we are all enjoying a few relaxing days on the beach or on the boat let’s do our part and “leave only footprints and take only pictures”, ok?

ADDITIONAL RESOURCES:

Learn more about marine debris from the short video by the Algalita Marine Research Foundation.

Also, here is an excellent example of what is being done to acknowledge the issue of marine debris and taking the effort to help eliminate it. Thanks, New Hampshire!

Here is a nice site that outlines what you can do to reduce your plastic footprint.

How do female terrapins navigate to a nesting site?

July 13, 2009 by Leave a Comment

The answer is “very carefully”.250px-Diamondback_Terrapin

Female terrapins need to look for a spot above the high tide line to lay a nest for their eggs (They lay on average 2 clutches of approximately a dozen eggs each summer).

The challenge is getting to a spot on the beach above the high tide line (dunes are usually the best spot) all the way from the estuaries (a.k.a. bays – spots where fresh and saltwater mix).

Terrapins lay their eggs at all times of day and night so you may see them venturing from the bay to the beach at anytime.

All too often you may see female terrapins crushed on the side of the road since a motorist was not paying attention as the female tried to make her way from the bay to the beach or back again. A good idea is to stop your car and let the terrapin continue across the road in the direction she was headed.

For more information check out the Northern Diamondback Terrapin Association.
