News from the deep: Oceana's crew aboard the Ranger has discovered a previously undocumented coral reef in the Alboran Sea in the high seas of the Mediterranean.
The reef, which is located more than 1,300 feet below the surface and covers over 1 million square feet, is formed primarily by white coral. With this discovery, Oceana with be able to glean additional data from the reef to support our efforts to declare new marine protected areas in the Mediterranean.
Coral reefs are the backbone of many marine ecosystems, and deep-sea corals area among the most vulnerable. Tragically, many reefs are destroyed by bottom trawling, a fishing technique akin to clear-cutting that devastates coral reefs and creates seafloor wastelands devoid of life.
And coral reefs aren’t the only habitats that suffer. The area around the newly discovered reef is flourishing with other important habitats including gorgonian gardens and rare glass sponge fields. In order to protect this region, Oceana is planning to present the data to the Barcelona Convention in the near future, pressing officials to list it as a protected area.
This is the eleventh in a series of posts about this year’s Ocean Hero finalists.
Today’s featured junior ocean hero finalist is 12-year-old Dylan Vecchione, who was nominated for his commitment to coral reef conservation.
Editor’s note: It’s not just the U.S. government that’s pushing to drill in our oceans. Guest blogger Jaime Matera is a marine anthropologist who is working to stop potential drilling off the coast of his home country, Colombia.
In 2010 the Colombian government opened up pristine coastal ecosystems in the Caribbean Sea to oil exploration. If allowed to continue, two petroleum companies, Repsol-YPF and Ecopetrol, would be drilling for oil on the second largest reef system in the Caribbean.
The Colombian archipelago of San Andres, Providencia and Santa Catalina lies on the southwestern Caribbean Sea, just 125 miles off the coast of Central America. It is home to an exceptional marine ecosystem and a native island population with strong connections to the resources.
The reef system surrounding the islands of Providencia and Santa Catalina is the second largest in the Caribbean. It covers approximately 255 km² and includes extensive sea grass beds, mangrove forests, and patchy reefs systems. In addition, a number of uninhabited cays and atolls are found in surrounding waters.

Bora Bora, Society Islands, French Polynesia – I dove last week in the beautiful lagoon that surrounds the tall island to have a first hand look at how the coral reef is doing in this South Pacific resort island. The report is not good.
Descending to 90 feet, it was immediately clear that the reef has been hammered in the past few years. I’ve come here every year for the past decade and have seen incredible change.
I spent most of the morning observing the still-growing reef system just 10 to 30 feet below the surface. Although the waters are warm and magnificently clear, invasive predators and natural disaster have both taken big tolls.
Populations of acanthaster -- also known as the crown-of-thorns starfish – mysteriously arrived in Polynesia in 2006. No one is sure exactly how they got here or where they originated, though invasive species are well known for hitching rides on cargo ships and jumping off far from home. Here in the shallows surrounding Bora Bora – as they have done to reefs on nearby Moorea, Raiatea-Tahaa, Huahine and Maupiti – the predatory starfish have devoured hundreds of acres of coral.
When you picture the impacts of climate change, what animal comes to mind? Is it a polar bear floating on a thin chunk of ice, or maybe another cold climate species losing habitat like a walrus or a penguin?
Add butterflyfish to your thoughts about climate change, because a new study predicts that they, along with one-third of all coral reef fish, are losing reef habitat and are locally threatened with extinction from climate change.
Coral reefs are threatened by two aspects of carbon dioxide emissions, ocean acidification and climate change. Corals are susceptible to sustained periods of warmer water temperatures due to climate change, which causes them to bleach when they expel algae, turning them white.

The worst flooding in 130 years has turned eastern Australia into a giant wading pond, killing dozens of people, wiping out crops and livestock, destroying tens of thousands of homes and shutting down hundreds of towns and cities.
At risk at the edge of Queensland’s shores is the nearly extinct dugong – the prehistoric marine mammal that looks part sea lion, part bulldog – that feeds off the sea grass that line the coast. Unfortunately the floodwaters are inundating those feeding grounds with sediment, topsoil, rubbish and all sorts of debris on top of toxic industrial and agricultural run-off.
Environmental officials are concerned that the floods will similarly destroy wetlands, coral reefs and marine parks along Australia’s coast. Fresh water kills coral reefs, though it remains to be seen what the long-term effects will be from this particular flood.
Every year the Endangered Species Coalition creates a report that focuses on 10 species facing extinction that are currently listed or being considered for listing under the Endangered Species Act.
This year’s report, It’s Getting Hot Out There: Top Ten Places to Save for Endangered Species, focuses on critical habitats that support endangered species and are themselves threatened by climate change. Shallow water coral reefs and Arctic sea ice, two important habitats that Oceana works hard to protect, were selected as two of the top 10 most important habitats to protect.
Last week in Belize, reef scientists, conservationists and managers gathered at the Belize Reef Summit to discuss the impacts of increasing ocean temperatures and ocean acidification.
Belize is home to the second largest barrier reef in the world. The 2010 Belize Reef Report Card, which was released at the meeting, reveals that 60% of this protected reef is in poor to critical condition with only 8% considered in good condition. This staggering statistic is unfortunately the case for many coral reefs worldwide.
On the final day of the summit, hundreds of Belizeans and international supporters gathered on an island on the Barrier Reef off of Belize City to create a living work of art to raise awareness about the effect of climate change on the oceans. This striking photograph was a call for world leaders to take strong action against climate change and ocean acidification at COP 16, the UN Climate Talks in Cancun that begin November 29th.
It was an exciting day yesterday on the Latitude, as Dustin reports. We owe a hearty thank you to Nautica, who is making this leg of the expedition possible.

The heat and humidity did not divert the Oceana crew from the important task at hand today.
After running a few more quick tests on the Spanish ROV, the crew sent it down for its first operation. Positioned near the “Alabama Alps,” the ROV was lowered nearly 250 feet to the ocean floor.
As strong underwater currents tried to move the Oceana Latitude from the operation site, expedition leader Xavier Pastor worked closely with the ships’ crew to ensure that all the necessary measures were taken to keep us on course.
Here’s Xavier Pastor:
Senior campaign communications manager Dustin Cranor is back on board the Latitude after a short hiatus on land, and he’s here to tell you about the latest leg of the expedition in the “Alabama Alps,” an ecologically rich reef in the Gulf of Mexico. More on that below in the video with our chief scientist, Mike Hirshfield.

As Will Race and the rest of our Alaskan colleagues headed back to Juneau this week, a new crew was making its way to Gulfport, Mississippi to board the Oceana Latitude.
Our next mission? Documenting seafloor habitat areas along the continental shelf of the Gulf of Mexico that may have been harmed by underwater oil.
During this leg, Spanish ROV operators Jose Manuel Saez and Josep Fleta will use a device to reach depths of approximately 1,500 feet and film in high-definition.
The Oceana Latitude also welcomed support divers Thierry Lannoy (France) and Jesus Molino (Spain), as well as Maribel Lopez from Oceana’s Madrid office. Dr. Michael Hirshfield has also returned to the ship. Here he is talking about this leg of the expedition:
