October 4: Storm damage

We watched the southern ocean pound the Isthmus throughout Saturday afternoon, and heard it roaring into the night. As we all awoke on Sunday morning we feared the worst for the elephant seals of the Isthmus.
Lone figures roamed around the station, quietly processing the extend of the damage, both on infrastructure, but on the wildlife. Pups washed away from their mothers bleated out, and female elephant seals cried out to try and find their pups. Many of the pups were  stuck in holes or erosion gullies and unable to reach their mothers. The little pups most only a few days old were so small and still quiet helpless, hat they were unable to  work their way back to the harem after being washed away the day beofre.  Some were already falling victim to the Giant Petrels, and others lay alone on the beach, facing certain starvation over the coming days. Macquarie Island is a nature reserve and we are not permitted to interfere with the wildlife, regardless of the circumstances.  Most of us found this very confronting, and heartbreaking.
Whilst we'd held out little hope for the seal harems on the west coast, which bore the brunt of the 17 metre seas, we were thrilled to discover that may of them and their pups had managed to seek higher ground up in the tussock.

October 3: The Storm

At 0515hrs on Saturday, most of us were awoken by the first strong gust of the storm. The buildings shaken so hard it was difficult to tell if it were the wind or an earth tremor! The weather due to build throughout the morning had arrived early. Throughout the morning gusts exceeded 60 kts, then 70 kts, topping out with a gust of 83 kts around 0900hrs. Around lunch time the seas began to build, lashing the west coast beaches with walls of whitewater. Elephant seal harems huddled on the highest ground they could find, but were soon at the mercy of the sea. Even two hours before high tide waves were washing over the Isthmus with such force that entire groups of seals, pups and even the big 3 tonne Beachmasters were washed away. Our concrete breakwater was washed out into the bay and the Isthmus slowly eroded under the relentless force of scouring surf. One large set washed through the Green Store and through market square, draining down between Cumpston’s Cottage and the Mess.
