CSIRO workers say they are still no closer to knowing exactly who will be made redundant following a meeting with management.

The ABC understands up to 350 positions will be affected, with most coming from the Oceans and Atmosphere division.

Almost 200 of the division's researchers work in Hobart, but staff are yet to be told which jobs will go.

CSIRO research fellow John Church said the lack of clarity was taking a toll on staff.

"Clearly staff are stressed, upset about their future," he said.

"They're dismayed about the performance of the CSIRO executive.

"Clearly there's not as much consultation as many people would like, and clearly there's a lack of understanding from our leadership on what it is exactly they're cutting."

The 90-minute meeting focused mainly on the itinerary of site visits over the next few weeks, with management to visit CSIRO offices in Tasmania, Victoria and Queensland.

The CSIRO said it was shifting its focus from climate measurement to long-term mitigation measures.

Federal Science Minister Christopher Pyne also asserted, during Question Time this week, the decision was made by management and not by the Government.
