Environmental groups are bracing for the Trump administration to approve controversial testing along the Eastern seaboard that would mark a significant step toward offshore drilling in waters off the coast of Florida all the way north to the Delaware Bay. The testing, which would cover 330,000 square miles of ocean, faces fierce opposition from environmental groups and local officials due to the possible economic and environmental effects. Seismic testing became a moot issue after President Barack Obama removed the Atlantic Ocean from the nation’s five-year program for oil and gas development in March 2016.
