A rare sighting

Leopard seals (Hydrurga leptonyx) are solitary animals that inhabit the pack-ice surrounding Antarctica. They have a fearsome reputation as top predators and eat almost anything from fish to elephant seals. Although they are mainly found in Antarctica, every so often a few venture North to see what the sub-Antarctic islands have on the menu.

The other day Chris was doing an elephant seal census from base to Repettos when he came across a juvenile leopard seal sleeping on the cobbles. That evening he radio'd us the news and the next morning Ryan, Maelle and I set off early to catch a glimpse of this incredible creature.


When we got to King Penguin Bay we found him sound asleep on a bed of kelp and were all quite stoked that he hadn't changed his spots.

He looks like a Loch Ness monster or a dinosaur! And the two humans like abominable snowmen!!
How big do they get, what makes them such fearsome predators?

Phytoplankton and Penguins

Phytoplankton are perhaps the most important group of organisms on our planet. They are microscopic, single-celled galaxies that come in many different shapes and sizes. They are the movers and shakers of our marine ecosystems that transfer energy into food webs. Without them, there would be no krill, fish, penguins, seals or albatrosses. Basically, phytoplankton use nutrients from the water and, together with sunshine, create energy (via photosynthesis) that enables them to grow and multiply. When conditions are just right, phytoplankton are capable of erupting into enormous blooms. Below is a satellite image of a phytoplankton bloom associated with upwelling along the edge of a meso-scale eddy north of South Georgia: The focus of my PhD is all about understanding the at-sea movements of two penguin species from Marion Island (the larger of the Prince Edward Islands). Because these penguins feed on krill, and krill feed on phytoplankton, peng...

To wed an island

As the tugs pulled the SA Agulhas away from the quayside I waved goodbye to my loved ones and stared out at the vast expanse of sea that lay ahead. ‘I won’t be seeing this place for more than a year!’ I thought to myself, acknowledging the strangeness of such a concept. A few hundred metres out to sea the feeling of adventure had already kicked in, as diving cormorants, porpoising seals, jumping dolphins and a lonesome sunfish filled the calm waters of the cape. The SA Agulhas isn’t the fastest of ships so the coastline stretching from Camps Bay to Cape Point took all the remaining hours of daylight to pass by, my eyes picking out some familiar spots; the Sentinel near Hout Bay, the BOSS 400 wreck off Sandy Bay, the crayfish factory at Witsands and all those beautiful beaches in the reserve. The last glimpse I shared with civilisation came from the haze of lights emanating from within the arms of False Bay; a lighthouse at the end of each warning ships, like ours, of their extremi...

Le petit manchot

As you may have guessed, the title is French, and manchot means penguin, but what does the word ‘penguin’ mean, and where does it come from? The intellect who gave me insight into this etymological mystery was the legendary David Attenborough. It was a dark, moody day and a light drizzle drifted playfully with the gusting squalls that moved alongside the cliffs. Every so often a stream of sunlight would break through the clouds and a rainbow would materialise over the wild seas. I was sitting next to my macaroni study colony and observing their ways whilst being audibly entertained by Sir David's intriguing stories. One particular story involved the now extinct Great Auk; a large flightless bird with a black back, white belly and upright posture, similar to the penguins we know today. Its distinctive features included a grooved bill, the sides of its neck and head were brown, and it had a large white patch in front of its eyes. Like penguins, the Great Auk spent most of...
