The Trump administration has drawn criticism for policies that environmental advocates say threaten the health and sustainability of the nation’s public seas. Since taking office, the administration has taken steps to curtail offshore wind power projects, accelerate oil and gas drilling, and roll back protections under longstanding environmental laws, according to ocean policy experts.

President Donald Trump has expressed opposition to offshore wind energy, a stance reportedly linked to the installation of turbines near his golf resort in Scotland. Following this position, the administration has sought to halt offshore wind developments along the Eastern Seaboard. Although federal courts have blocked some attempts to stop these projects, the administration has spent about $4 billion encouraging companies to halt construction on wind initiatives in favor of expanding oil and gas exploration. Efforts also include pushing for new offshore drilling leases off the West Coast and Alaska, moves that critics argue overlook existing environmental regulations.

The administration’s approach has included attempts to limit California’s authority over coastal protection under the Coastal Zone Management Act, labeling the state's policies as excessively stringent. California, one of the largest economies globally if considered independently, has resisted these efforts. Meanwhile, an initiative to dismantle the $386 million Ocean Observatories Initiative, which monitors ocean conditions, faced widespread opposition and was halted after some deep-sea sensor arrays off Oregon were decommissioned.

Within federal agencies, the National Oceanic and Atmospheric Administration (NOAA) has seen significant staff reductions and the removal of experienced personnel, interpreted by some as political interference that undermines scientific research. Executive orders have also opened national marine monuments to commercial fishing, a move currently challenged in court.

Further controversies involve the rapid approval of deep-sea mining leases near American Samoa and in international waters, raising concerns about violations of the United Nations Convention on the Law of the Sea, which the United States has not formally ratified but traditionally honored. Plans to expedite the deployment of offshore nuclear power facilities are also underway.

The administration’s policies have drawn attention for their potential impacts on endangered marine species, such as sea turtles and North Atlantic right whales, as well as on seafood safety and greenhouse gas emissions. Critics further highlight incidents involving the extrajudicial killing of suspected drug smugglers at sea in Latin America, actions some characterize as violations of international maritime law.

Environmental advocates emphasize that these developments come amid a period of intensified climate-related challenges, including marine heatwaves, a strong El Niño pattern, and corresponding threats such as coastal flooding, severe drought, and extreme storms.

With midterm elections scheduled for November 3, ocean policy groups urge voters to consider candidates’ environmental records closely. Evaluations by organizations like the League of Conservation Voters aim to help constituents identify lawmakers who support ocean and climate protection. Experts caution that party affiliation alone may not fully reflect a candidate’s stance on these issues, encouraging voters to research local, state, and national contenders who prioritize the health of marine ecosystems alongside economic and cultural interests.
