"Thank you to everyone who has taken part in the Natural Environment Research Council's Name Our Ship campaign," they posted online.
"We are no longer accepting suggestions to name our ship as we have now reached the closing date.
"We've had an extremely high volume of suggestions and will now review all of the suggested names. The final decision will be announced in due course."
Boaty McBoatface is probably not the sort of name they had envisaged when launching the competition back in March.
Universities and science minister, Jo Johnson, said at the time: "Can you imagine one of the world's biggest research labs travelling to the Antarctic with your suggested name proudly emblazoned on the side?
"The polar research ship represents a leap forward in securing Britain's place as a world leader in marine and climate change science - and illustrates this government's commitment to invest in research facilities on a record scale.
"With the eyes of the world on this ship, this campaign will give everyone across the UK the opportunity to feel part of this exciting project and the untold discoveries it will unearth."
The ship, backed by £200 million of government funding, will be built at the Cammell Laird shipyard on Merseyside and is set to sail in 2019.
Pingu, It's Bloody Cold Here, Usain Boat and What Iceberg were just a few of the thousands of suggestions by the public in the vote.
BBC Radio Jersey presenter James Hand, who suggested the Boaty McBoatface name, "apologised profusely" to NERC, adding: "It's all been really good fun".
