Tackling Ocean Acidification in Florida

Posted On July 6, 2016 by

As the state representative for the Florida Keys and South Miami-Dade County, there are few things more important to our well-being than the health of our unique marine environment. We are home to the Everglades, the 3rd largest barrier reef in the world and the only living barrier reef in the continental United States. Since I took office, I have made it a priority to do everything I can to help raise awareness about our water issues in Tallahassee and we’ve made great progress in the last four years when it comes to improving water quality.

Despite this progress, there are still many stressors facing Florida’s oceans and ocean acidification (OA) is a particularly significant threat. Its impacts on our marine ecosystems are less visible so it has not been as widely discussed as other environmental threats, but that is starting to change, and I am excited to help bring further awareness to this issue. Side effects of acidification like decreases in coral reproduction, growth and calcification as well as slower shellfish growth mean that this is not an issue we can afford to ignore. Already, other fisheries across the country are seeing serious economic impacts from OA and if it continues unchecked, the impacts to Florida businesses and residents could be equally devastating.

Poles Apart: The Differences between Antarctica and the Arctic

Posted On June 30, 2016 by

This blog was written by Roger Di Silvestro, a field correspondent for Ocean Conservancy.

Have you ever seen a cartoon or advertisement that showed penguins and polar bears cavorting together in the snow?

On the flip side, have you ever seen a documentary film that showed penguins and polar bears together in the wild? Didn’t think so, since they live poles apart. Nevertheless, not everyone (advertisers included) understands the difference between Antarctica and the Arctic. Here are eight ways to tell them apart.

10 Things to Know About Sea Turtles

Posted On June 16, 2016 by

This blog was written by Roger Di Silvestro, a field correspondent for Ocean Conservancy.

Sea turtles are among the world’s most ancient vertebrates. When on land, they look cumbersome and awkward, their powerful front flippers struggling to pull their weight across ocean shores. But in the water, where they spend most of their lives, sea turtles fly through the water much as birds soar through the sky. Their flippers become wings, their disk-shaped bodies cut through the sea like torpedoes.

Sea turtles remain one of nature’s great mysteries—scientists have only begun to discover secrets of sea turtle life. Here are ten things science can tell you about these marine animals.

What Inspires a Spear Fisherman to go to Capitol Hill?

Posted On June 10, 2016 by

Captain Scott Childress owns and navigates a commercial spear fishing vessel located in Hudson, Florida.

When Ocean Conservancy asked me to join them to visit elected officials on Capitol Hill to celebrate the 40th anniversary of Magnuson Stevens Fishery Conservation and Management Act (MSA), I was quick to say a resounding “yes,” but a little nervous about my new role.

What the heck would I—a commercial spear fisherman—say to congressmen? As it turned out, quite a lot. I have a unique perspective on fishing in the Gulf of Mexico and on the U.S. law that has served as “tough love” for America’s fisheries.

10 Things to Know About the Walrus

Posted On May 19, 2016 by

This blog was written by Roger Di Silvestro, a field correspondent for Ocean Conservancy.

When you think of walruses, you may picture their tusks—the huge pinniped’s most familiar characteristic. But there is so much more to these “elephants of the sea”! Here are some less-obvious facts about these ice-dwelling creatures.

1. Biologists classify the walrus as a carnivore, or meat eater, which puts the animal in the same broad category as wolves, foxes and lions.

2. The polar bear, weighing as much as 1,200 pounds, is often touted as North America’s largest terrestrial carnivore. But it’s a mere wisp compared to the ocean-going male walrus, which can tip the scales in excess of 3,700 pounds.

10 Things to Know about Penguins

Adelie penguin

This blog was written by Roger Di Silvestro, a field correspondent for Ocean Conservancy.

The tuxedo seems to have two separate origins. Why the fashion industry came up with the tux, and why it hasn’t vanished with the top hat, is tough to say. But why penguins evolved into tuxedo-wearing birds is pretty clear: The white belly makes them harder to spot when viewed in water from below against the surface of a sunlit sea, and the black back does the same against the dark ocean surface. It’s all about tricking predators. The survival of this monochromatic color scheme in all 17 penguin species is a measure of how well it has worked in nature’s often-unforgiving game of survival.

Here are ten other fun facts to know about penguins.
