RV Whale Song at sea
We have a visitor at the museum! Whale research vessel Whale Song arrived last Thursday and will be moored at the museum wharves until 21 January.
On Thursday, I went onboard to have a look around. During my visit I met Curt and Michelle who live and research on the vessel with their daughter and two professional crew… Oh, and Skipper their fiesty little watch dog! Curt and Michelle generously showed me around the vessel and told me about their facsinating whale research.
I learnt that Whale Song is an ice class research vessel specifically built to conduct whale research throughout the worlds’ oceans. Her hull and machinery are sound dampened so that whale songs can be heard using towed acoustic arrays (a series of underwater microphones) while the vessel is underway. She may be one of the few vessels, besides navy submarines, that was ever designed to operate silently like this. She has forward searching sonar and military spec night vision cameras (which we tested out, but no whales in Darling Harbour!) for locating whales in the most challenging conditions from the tropics to the poles.

Curt also showed me the impressive three dimensional real time bottom mapping software that allows scientists onboard to map canyons and seamounts where they find whales.
Most recently the team have completed the second season of a five year program funded by US oil and gas giants known as the Joint Industry Partners. The project operated from Perigian Beach to the Queensland Sunshine Coast and examined the behavioural affects of seismic air guns on migrating humpback whales. Prior to that, Whale Song was in the Kimberley region measuring blubber thickness with stereo cameras set up on her gimballed 12m boom crane and applying satellite tags to northbound humpback whales off Western Australia’s Ningaloo Reef.
After a brief stop in Sydney, Whale Song will head south around the bottom of Australia, studying pygmy blue whales, killer whales and sperm whales enroute to Fremantle where she will finish her first circumnavigation of Australia. The following months will be spent satellite tagging blue whales and humpback whales in preparation for an expedition to the Antarctic in the summer of 2012/2013.
