SYDNEY — A pre-eminent scientist in the field of rising global sea levels has been given notice of his dismissal as part of deep cuts at Australia’s national science agency that will reduce the country’s role in global climate research.

The scientist, John Church, confirmed Tuesday that he was one of 275 scientists whom the agency, the Commonwealth Scientific and Industrial Research Organization, or Csiro, said would be laid off.

“I am impacted by the Csiro restructure and business plan,” Dr. Church said in an email from the Australian research vessel Investigator, where he was taking water measurements in the Ross Sea off the Antarctic ice shelf. He said he had been informed that Csiro was “consolidating” the team studying the effects of sea level change and “ceasing work” on rising sea levels.

The layoffs and shift in direction at Csiro — away from climate research and toward more commercial projects — created a public outcry when they were announced in February.
