This Week’s Top Tweets: January 19 – 25

Posted On January 26, 2013 by

It’s time to recap the Ocean Conservancy tweets that made the most waves (get it?) in the past week. Check out our top five and let us know which one piqued your interest the most!

1. Would You Like Some Fish with Your Plastic?

This was our top tweet of the week and it’s no wonder why–finding out that over one third of a given sample of fish have plastic in their bellies is downright creepy. This study by Plymouth University and the UK Marine Biological Association illustrates the tangible effects that trash has on our ocean. If you’re looking for ways to lessen your impact and to keep the ocean healthy, try downloading our mobile app, Rippl. You’ll get weekly ocean-friendly tips and be able to track your progress!

An Island of Hope for Coral Reefs

I’m accustomed to getting bad news about the state of the world’s coral reefs, but this week there’s some good news for a change.

Scientists have just released findings from their research in American Samoa on especially tough species of corals that are adapting to warming waters and may be resisting climate change.

In a new paper published by Ocean Conservancy board member Dr. Stephen Palumbi and other scientists in the Proceedings of the National Academy of Sciences of the United States of America, the scientists found that some reef-building corals are resistant to the stress of warmer waters that cause coral bleaching.

While studying corals in American Samoa, researchers found heat-resistant corals can survive damaging temperature increases by switching on a set of 60 genes before the stress has occurred. Heat-sensitive corals switch these genes on after stress has already occurred. This means that some corals have the ability to withstand future increase in ocean temperature.

DNA sequencing can offer broad insights into the differences that may allow some organisms to persist longer amid future changes to global climate.

NOAA Moves to Protect Corals

Corals are in trouble, but they could soon receive the help they need.

The National Oceanic and Atmospheric Agency (NOAA) proposed listing 66 species of reef-building corals under the Endangered Species Act (ESA), which is a step in the right direction for coral conservation. Being added to the Endangered Species list is more than a title upgrade (or downgrade, really). Listing species as endangered would prohibit harming, wounding or killing the species. It also prohibits the extraction of listed species, which includes importing or exporting the corals.

What has made these corals candidates for the list? A number of things: pollution, warming waters, overfishing and ocean acidification threaten the survival of corals. These threats can make corals more susceptible to disease and mortality. Protections like endangered species listing are vital to preserving coral from threats and helping them cope with changing environmental conditions.

Corals are tremendously important economically and environmentally. Corals provide habitat to support fisheries that feed millions of people; create jobs and income for coastal economies through tourism, recreation and fisheries; and protect coastlines from storm damage. One independent study found that coral reefs provided about $483 million in annual net benefit to the U.S. economic from recreation and tourism activities. Marine life, such as fish, crustaceans and sea turtles rely on corals for food, shelter and nursery grounds. Over 25% of fish in the ocean and up to two million marine species use coral reefs as their home. Because of their significance, supporting NOAA’s proposed ESA listing for 66 coral species is incredibly important to their survival and our local economies.

Can 500 Underwater Statues Help The Ocean?

Posted On August 23, 2012 by

Underwater statues are fun to look at, but can they really function as an artificial reef? Credit: Jim Bahn flickr stream

Two of my favorite pastimes are visiting art museums and exploring new underwater habitats. But combining the two can be environmentally risky. That’s why there are a couple of things that concern me about Jason deCaires Taylor’s project in Cancun, Mexico, that has placed 500 statues as an underwater tourist attraction. Here are a couple questions I asked myself after hearing about the site.

1. How does it help ocean health?

The artist, Jason deCaires Taylor, mentions that his statues at Museo Subacuático de Arte (MUSA) are being covered with coral and algae, but this does not necessarily mean his statues are helping the ocean. When implementing artificial reefs, the placement of human-made structures onto the seafloor, you need to have biological goals in place. This ensures that your artificial reef, or 500 statues in this case, contains organisms that can co-exist in a way that mimics the natural food web over time instead of throwing it out of balance.

2. Are the statues secure? Continue reading »

Pearls of Wisdom: Medicine of the Sea Answer

Posted On June 3, 2012 by

TRUE: Ancient Greek dentists used the venom from the stingray’s spine as anesthetic.
TRUE: Doctors once used Asian carp as a test for pregnancy.
FALSE: Amazon explorers took a medicine derived from coral to fight off malaria.

Coral has not been used to fight off malaria, but that doesn’t mean it doesn’t have real medicinal promise. In fact, coral reefs are often called “the medicine cabinet of the 21st century.” Coral reef-based medicines are being developed to treat cancer, arthritis, heart disease, viruses, and more–yet another reason to protect these delicate ecosystems. You can learn more about why coral reefs are so important from NOAA here.
