Life’s A Boat

I may have swapped rooms but my new window view is just as stunning

As you may be aware from my previous post, I have exchanged my South Georgian life for life at sea for three weeks. I am working on board a krill fishing vessel, researching by-catch (which is minimal) and also making whale and seabird observations to inform future conservation decisions.

Seemingly, I am here at a good time of year since within seconds of leaving Cumberland Bay, we were seeing the first spouts as whales blew all around us with the sun setting.

Whale sightings were immediate, once out of Cumberland Bay

As we set about fishing, sightings continued, predominantly of Humpbacks, which were obviously exploiting the rich masses of krill 200m beneath the surface. When you see a distant whale blow, it’s easy to forget what is lying beneath. These Humpbacks can measure 16m and weigh up to 36 tonnes.

As the days have progressed, the sightings are getting better and better with several species seen so far. Fin, minke, southern right, sperm and orca (not seen by me!) were all spotted, as well as thousands of seabirds, seals and penguins.

South Georgia was the hub of whaling in the not too recent past and estimates suggest that numbers of baleen whales reduced by 90% as a result of it. So it’s absolutely incredible to see such high densities of whales in these waters.

The most frequent bird sightings involve the petrel species, with South Georgia Diving, Kerguelen, Great Winged, Antarctic, Cape and Giant Petrels all present in various numbers. Both Southern Fulmers and Antarctic Terns are also abundant with the occasional Wandering Albatross sightings.

Conditions on the whole have remained calm and clear, allowing good sightings throughout the trip. With the boats moving at very slow speeds, animals tend to pay little attention to the vessel, allowing for up close sightings.

Humpback whales migrate south for summer to feed on the krill rich numbers. These animals will be on their way north back to their breeding grounds, where they will breed in August time.

Although it is the wrong time of year, I have seen several humpbacks displaying, launching their magnificent bodies out of the water. One of these was close enough for me to capture on camera!

As mentioned before, the birdlife has been almost as spectacular as the marine mammals. See my previous blog (feeding frenzy) for more bird pictures

South Georgia hosts some of the most spectacular wildlife colonies in the world. People pay thousands of pounds and travel from all over the world to visit. Our most famous inhabitants are the penguins (4 species), seals (2 species) and albatross (4 species). There is an abundance of less ‘sexy’ wildlife utilising South Georgia for its breeding habitats and proximity to rich foraging grounds. Many of these species can be very elusive on the islands, breeding down burrows, visiting nesting sites in the dark and living predominantly over open ocean. This has meant sightings have been few and far between from base. I have spent the last two weeks on board a vessel in the southern ocean and this opportunity has allowed me time to see some of these scarcer pelagic species

Probably the most common of these pelagic species around boats are the cape petrels (seen above), often spotted cruising in the slipstream of ships in the southern hemisphere. As a result, I have a number of the same shots of capes in flight. However, it was a great surprise to see one diving and fishing alongside our ship. The bird must have unearthed a small quantity of krill since it wasn’t long before other species were investigating – like this Antarctic Petrel.

Finally it was the turn of the most elusive of them all, the Blue Petrel. I have spent hours on board ships trying to get pictures of these guys. Although common around boats, they tend to keep their distance. They also move incredibly quickly, meaning previous attempts have been limited to blurry distant unidentifiable specs. When this bird came in close to take advantage of the easy krill meal, I was thrilled. Unfortunately, the sun decided it was a good time to hide away but you can’t have everything!
