Restoration Report Card: Gulf Council Fails at Public Participation

Posted On August 21, 2014 by

Today the Gulf Coast Ecosystem Restoration Council made some big announcements and provided more information on how they will choose projects to restore the Gulf. We’ve graded the Council’s efforts today, and the results are a mixed bag.

How Do We Restore the Gulf Beyond the Shore?

Posted On August 18, 2014 by

In the wake of the BP Deepwater Horizon oil disaster, everyone’s talking about how we restore the Gulf Coast. But the Gulf of Mexico is more than what we can see from the shoreline. If we restore the coast without restoring the deep waters, we’re only addressing half the problem.

That’s why Ocean Conservancy has created Restoring the Gulf Beyond the Shore. It’s a short guide to the wildlife that lives in the Gulf’s waters and it explains why it is so important that we ensure the health and safety of our fish, dolphins, seabirds, and whales (yes, whales in the Gulf!).

Interview: Deep-Sea Researcher Dr. Samantha Joye on Microbes in the Gulf

This blog is part of a series of interviews with scientists who are championing marine research in the Gulf of Mexico.

Dr. Samantha Joye is a Professor of Marine Sciences in the University of Georgia in Athens, Georgia. She is an expert in biogeochemistry and microbial ecology and works in open-ocean, deep-sea and coastal ecosystems. Her work is interdisciplinary, bridging the fields of chemistry, microbiology and geology. Following the BP Deepwater Horizon oil disaster, Dr. Joye joined a team of scientists in the Gulf, investigating oil plumes from the disaster in the open ocean of the Gulf, which at the time BP claimed did not exist. Her team’s discoveries proved that there was more oil and gas in the water than BP and government agencies had predicted. She continues to study the impacts of the BP oil disaster, as well as the ecological processes at natural oil and gas seeps in the Gulf, Arctic Ocean and in the Guaymas Basin.

BP Oil Marring Deep-Water Corals 13 Miles Out

Deep-water corals keep good records, which come in handy in the case of the BP Deepwater Horizon oil disaster. Researchers from Penn State University discovered this week that the impact of the BP oil disaster on corals living in the cold waters at the Gulf of Mexico seafloor is bigger than predicted.

This study joins dozens of others on fish, dolphins and birds as part of the ongoing Natural Resource Damage Assessment, a legal process that’s critical for tracking the damage that started four years ago at the bottom of the Gulf. Scientists first discovered corals coated in a brown substance only 7 miles from the now-defunct BP well in late 2010. The oil left over from the disaster is more difficult to find in the deep sea (in contrast to the coastline, where the occasional 1,000-pound tar mat washes up on shore), so scientists must look to corals for clues on how the marine environment was impacted. “One of the keys to coral’s usefulness as an indicator species is that the coral skeleton retains evidence of the damage long after the oil that caused the damage is gone,” said lead researcher Charles Fisher.

Fishermen and Scientists Work Together to Track Sick Fish

Fishermen are on the water every day, which means they are often the first to notice when something changes. After the BP Deepwater Horizon oil disaster, we heard reports from fishermen that they were catching more fish with lesions than they had ever seen before. Immediately after hearing these reports, Dr. Jim Cowan at LSU began investigating the frequency, location and cause of the reported lesions. Many other scientists have collected data on this same issue, and last week a group from the University of South Florida published the first round of results in a scientific journal.

A Victory for Gulf Sea Turtles

Posted On July 14, 2014 by

Blair Witherington

Last September, we asked you to help us protect the Gulf’s sea turtles and today, I have some wonderful news to share. Thanks to more than 5,000 of our supporters, 685 miles of beaches and nearly 200,000 square miles of the Atlantic Ocean and Gulf of Mexico have now been declared critical habitat for threatened loggerhead sea turtles. The newly protected areas include floating Sargassum mats, where young sea turtles live and grow.

Troubling News for Mahi-mahi in the Gulf

Posted On June 20, 2014 by

As we watched the BP Deepwater Horizon oil disaster unfold on beaches and in bays of the Gulf of Mexico four years ago, we wondered, too, about the impacts beyond what we could see on shore. Some of the answers to that troubling question are rolling in. We previously learned about damage to fish embryos, and the latest news involves mahi-mahi, or dolphinfish. These fast-growing, colorful predators are a favorite target of recreational fishermen and restaurant-goers alike across the Gulf, and despite their savage speed, it seems they could not outrun the impacts of BP’s oil.

A new study from the University of Miami last week demonstrated that even “relatively brief, low-level exposure to oil harms the swimming capabilities of mahi-mahi, and likely other large pelagic fish, during the early life stages.” And while it’s troubling to hear that oil reduces the fish’s ability to swim fast – a necessity for finding food and evading predators –the more disturbing revelation is how little oil exposure it takes to cause this damage to such an economically important fish.
