Water holds significantly less oxygen than air, a problem exacerbated as water temperatures rise. This reduction in available oxygen creates a critical challenge for aquatic life.

As our oceans warm, fish and other marine species struggle to breathe. Learn more about the profound impacts these changing conditions have on their survival and the broader ecosystem.

Last year, Oceana celebrated significant victories for our oceans. New global laws and protections were established, safeguarding precious marine life worldwide.

Yet, the vital work continues. Help us sustain the fight for ocean protection in 2016 by making your year-end gift today: http://bit.ly/1QGix0w.

The Obama Administration's proposal to open the Southeast coast to offshore drilling threatens jobs, tourism, and risks devastating oil spills. Communities, elected leaders, and industries across Virginia, North Carolina, South Carolina, and Georgia oppose this plan. The administration is currently reexamining and revising its proposed leasing plan.

Seismic airgun testing, used for offshore oil and gas, poses a severe threat to the ocean's soundscape. These powerful blasts injure marine life, endanger regional fisheries, and jeopardize the livelihoods of those dependent on the ocean.

The Bureau of Ocean Energy Management (BOEM) is currently preparing an environmental impact statement (EIS) on expanding seismic testing in the Mid and South Atlantic. BOEM must incorporate the latest science to fully assess these risks. Help raise awareness about this destructive practice. For more information, visit: http://oceana.org/seismic.

Proposed seismic airgun testing in the Atlantic Ocean threatens to injure thousands of whales and dolphins. Oceana is campaigning to stop this harmful activity before it begins.

Support Oceana's efforts. Please sign their petition to stop seismic testing on the White House's website: Stop Seismic Airgun Testing Petition.

Over 1.3 million small-scale fishers in the Philippines, among the nation's poorest, depend entirely on the ocean for their livelihood and to prevent hunger. Learn more about their situation: http://bit.ly/1j7zbrq

Unfortunately, these vital Philippine waters are in crisis. Over 75% of fishing grounds are overexploited, once vibrant coral reefs are degraded, and whale sharks face accidental deaths.

By acting together now, we can restore the ocean's abundance and secure the future for these communities.

Oceana's "One Name One Fish" report emphasizes the critical need for species-specific names for all seafood throughout the supply chain. Understand the full case by reading the report: oceana.org/onenameonefish.

Deafening seismic airgun tests are proposed for the Atlantic. We must urge the Obama administration to halt these tests.

Actress Kate Mara ("House of Cards") is partnering with Oceana, driven by her passion for oceans and wildlife. Together, they aim to remove drift gillnets from the water.

These nets indiscriminately entangle and kill thousands of non-targeted marine animals annually, including whales, dolphins, and sea turtles. Watch Kate's powerful call to action against this destructive practice.

There are seven species of sea turtles, with green turtles living up to 80 years.

On World Sea Turtle Day, Lilimar, Oceana, One More Generation, and children nationwide delivered over 12,500 letters and drawings to the White House. These messages urged President Obama and Secretary Penny Pritzker to protect threatened and endangered sea turtles in U.S. waters.

Representing all 50 states, the letters called for a simple solution: mandatory use of Turtle Excluder Devices (TEDs) in shrimp nets. These metal grates allow sea turtles and other marine life to escape, preventing their capture by shrimp trawls in the South Atlantic and Gulf of Mexico.

Implementing TEDs would save thousands of sea turtles, reduce seafood waste, and create new markets for U.S. shrimpers.

For 45 years, the Marine Mammal Protection Act (MMPA) has provided vital protections for dolphins, whales, and seals in U.S. waters.

Unfortunately, a new congressional bill threatens these safeguards. It would facilitate harmful activities like seismic airgun blasting—a loud, dangerous process used for oil and gas exploration—making it easier to injure these iconic animals.
