Corals are Like… What?!

Posted On July 25, 2016 by

This week we’re celebrating all things coral! It’s no secret that coral reefs are spectacular ecosystems, but we wanted to do a deep dive into what exactly makes corals so special. Check out nine ways corals are even cooler than you thought:

1)  Corals are like speed bumps. They slow down waves and lessen wave energy. This protects coastlines from hurricanes, cyclones and tsunamis. Coral reefs protect the shoreline in 81 countries around the world, sheltering the 200 million people living along those coasts.

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.

How Ocean Acidification Impacts Florida’s Ecosystems

Dr. Kimberly Yates will be a panelist at an ocean acidification roundtable we are hosting in Miami this week. There, she will join other scientists, Florida elected officials and local businesspeople in discussing what ocean acidification has in store for Florida’s marine life and its coastal communities. Follow the meeting on Twitter via #FL_OA on Friday, June 17!

OC: Your research focuses on several marine habitats in Florida: coral reefs, estuaries and mangroves. How are they coping with ocean acidification?

Dr. Yates: Most of what we know about how ocean acidification is affecting these environments comes from experimental research. We know some marine organisms will be negatively impacted, and some may benefit. For example, some species that form their skeletons and shells from minerals made of calcium carbonate, like corals and some shellfish, are negatively impacted. Ocean acidification slows the rate at which they grow their skeletons and shells, and can also cause calcium carbonate minerals to dissolve.

Other species like seagrasses and some marine algae benefit from ocean acidification because it increases their growth rates. Coral reefs have been degrading rapidly over the past few decades, and recent research shows that some reefs in the Florida Keys are beginning to dissolve during certain times of the year from ocean acidification…which was not expected to happen for another few decades. Estuaries and mangrove wetlands support many species of shellfish, and ocean acidification may negatively impact those species and the economies that depend on shell fisheries. We are still learning about how changes caused by ocean acidification are impacting these habitats.

Q&A with Coral Reef Expert Danielle Dixson

Posted On December 2, 2015 by

Ocean Conservancy is bringing Danielle Dixson, an expert on coral reef fishes, to Capitol Hill to speak to congressional staffers about ocean acidification. She will be participating in a panel hosted by Ocean Conservancy in partnership with Senator Mazie Hirono (D-HI) and Representative Mark Takai (D-HI), along with the Ocean Caucus. She recently took some time to speak with us about her work at the University of Delaware.

5 Questions with International Coastal Cleanup Coordinator Hilberto Riverol of Belize

Posted On September 15, 2012 by

Since 1911,  The Scout Association of Belize has taught children to protect and care for the environment on a daily basis. As it happens, their small Central American country on the Caribbean is a rugged place of great natural beauty. Coastal waters host extraordinary marine life, especially along the world’s second largest barrier reef, a UNESCO World Heritage Site.

So back in 1992 when Hilberto Riverol, national scout executive with the association, heard that the Ramada Hotel in Belize City was gathering volunteers for the country’s first International Coastal Cleanup, he signed up.  Some 600 participants including the scouts removed more than three tons of trash from approximately 18 miles of the coast.

Building a Mosaic of Restoration Projects for the Gulf

Posted On July 19, 2012 by

The BP Deepwater Horizon oil disaster harmed communities from Texas to Florida and damaged the Gulf ecosystem from the ocean floor to the surface across a vast swath of waters and shoreline. Restoring these damaged resources will require a comprehensive, Gulf-wide restoration plan that covers coastal environments, blue-water resources and Gulf communities.

Because wildlife like birds, fish and marine mammals move throughout the ecosystem making use of coastal, nearshore and offshore environments, effective restoration requires a holistic approach. For example, restoration efforts for oyster reefs or barrier islands in Texas should complement the work done in Alabama or in Florida so that the full suite of species and habitats can recover.

The state and federal officials responsible for creating such a plan, the Natural Resources Damage Assessment (NRDA) Trustees, are making decisions about how to spend the balance of the $1 billion committed by BP for early restoration. The decisions they make about early restoration and about the longer-term restoration program to follow have the potential to pay enormous dividends to the Gulf for generations.

To help the Trustees build an effective plan, a coalition of nonprofit groups, including Ocean Conservancy, has created a portfolio of 39 projects that reflect an integrated and Gulf-wide approach to restoration. Continue reading »

Of Fear, Hope, and the Future of Our Ocean

Posted On July 17, 2012 by

As an ocean scientist I am personally familiar with the struggle between dread and hope. This duality is deeply entwined in all of our work here at Ocean Conservancy. Understanding the seriousness of what ails the ocean and what it will take to address these problems often keeps me up at night. But it is the knowledge that much can be done to turn the tide – that there is hope for our oceans – that gets me out of bed each morning.

Anxiety can be paralyzing. But if we let fear over the extent of the ocean’s problems overwhelm us, the future will undoubtedly be bleak. Yet, so too can false hope also prevent timely or adequate action or send us in search of solutions not based on scientific fact. We must face this scientific reality if we are to address the seriousness of the challenges before us.

Last week, The New York Times published a powerful opinion piece starkly laying out an ocean future devoid of coral reefs. Corals are under assault from a “perfect storm” of overfishing, ocean acidification, and pollution and their future is very much at risk. But the piece’s author Roger Bradbury went further, concluding that “there is no hope of saving the global coral reef ecosystem” and accusing conservationists of “persisting in the false belief that corals have a future.” He calls for a radical reallocation of funding from trying to save coral reefs to coping with the fallout from their inevitable collapse.
