Lawmakers are demanding the National Science Foundation stop dismantling the Ocean Observatories Initiative, a $386 million ocean monitoring network being wound down under President Donald Trump’s administration. House Democrats on two committees call the action illegal. Democratic Sen. Jeff Merkley says he’s drafting legislation to freeze the removal of instruments until a full scientific review is completed. The National Science Foundation directed the removal of most of the system’s instruments from waters off Oregon, Washington, Alaska, North Carolina and Greenland by 2027. Monday’s pushback against the Republican administration’s actions comes as scientists are set to remove instruments from the Pacific and as an El Niño event is predicted to arrive this summer.
