Residents across the Gulf Coast breathed a sigh of relief last weekend as Tropical Storm Karen dissipated (and as an added bonus, the humidity dropped). But as many of us feared, the storm kicked up more oil in the Gulf as it passed, and a fresh batch of tar balls have washed ashore on Grand Isle, La.
This is an ugly reminder that oil still lurks offshore, and we have not yet seen the end of the oil’s impacts on the Gulf.

NOAA recently released several photos of a dead sperm whale found in the Gulf of Mexico just a few months after the BP Deepwater Horizon oil disaster began. While NOAA’s scientists were unable to determine the cause of death, this story does serve as a very graphic reminder that more must be done to protect the marine life in the Gulf.
This whale is one of two dead sperm whales that have been reported in the oil spill area of the Gulf. Two whales may not seem like much, but sperm whales are a federally listed endangered species in the United States, and even a small number of deaths could seriously impact their population.
Sperm whales, which can live up to 70 years, can be found year-round in the northern Gulf, and they are especially common near the Mississippi Canyon, where the Deepwater Horizon oil rig was located. Sperm whales spend most of their time in deep water, diving to the ocean bottom to snack on giant squids and other ocean creatures. With all that diving throughout the water column, it’s possible the whales were exposed to oil or dispersants. The hustle and bustle of oil spill response activities can be equally harmful.
Should we be worried? Continue reading »

As George Leonard wrote recently, planning for a stormier, warmer ocean is a daunting but important task. That’s already a reality for those of us living on the Gulf Coast, where sea level rise (compounded by coastal erosion) can almost wash away an entire community.
With near-perfect timing, another new study has just revealed that sea grasses can trap 2 to 3 times more carbon than a typical forest. The ocean, not just forests, can play a larger role than scientists previously believed keeping carbon out of the atmosphere. Continue reading »
