Scientists are back on the ground at Heard Island after an enforced absence due to the weather. Making the most of brief weather windows on Tuesday and Wednesday, helicopter flights deployed 20 people to the island.

The Atlas Cove camp was re-established and prepared for further helicopter operations. Scientists will continue their research on plants and invertebrates, as well as recording (and gathering) marine debris and waste at the old station.
Biologists were deployed to Fairchild Beach to conduct population surveys of seals with others deploying to Skua Beach to continue gathering data on different seabirds.
Researches from the Securing Antarctica's Environmental Future (SAEF) team went into Paddick Valley to continue their work on invertebrates and mapping the non-native grass species, Poa annua, using both ground and aerial surveys.
An ARTEMIS system was installed at Atlas Cove. This is an autonomous weather station equipped with a high-resolution camera that can provide real-time data and imagery back to Australia.
Four cage pallets of cargo were returned to the RSV Nuyina from Atlas Cove. This included a full cage of asbestos cleaned-up from the old station - an excellent result for the management of the island.
These science teams will stay ashore until Sunday, while the ship heads out to sea, southwest of the island, to conduct further marine science. This includes a planned midwater trawl, which samples sea life from six different depths within the water column.
Other work has continued during the bad weather days, despite strong winds. RSV Nuyina spent a day near the McDonald Islands, using drones to investigate wildlife populations. We found (and photographed) a huge macaroni penguin colony, king penguins, fur seals and elephant seals.
While scientists were remotely observing the island via drone, penguins, petrels and other birds came out to conduct their own investigation of our ship! They stayed at a comfortable distance, but gathered in significant numbers in the sky and on the water around us.
It will be fascinating to see what we achieve through the next phase of marine science, and hear from the terrestrial scientists on their return to the ship.
