8 Dec 25 - Antarctica 25 - Half Mooning In The South Shetland islands

I awoke to find we were still crossing the Bransfield Strait, between the Antarctic Peninsula and the South Shetland Islands. The crossing was good for Whales with four Humpback Whales, brief views of a Fin or Sei Whale and three other Whale blows. After breakfast, Livingston Island and Greenwich Island came into view. Our first destination was Half Moon Island, which is a small rocky island located within a sheltered large bay on Livingston Island's East coast. The plan for to visit the modest Chinstrap Penguin colony on Half Moon Island.
Approaching the South Shetland Islands: Livingston Island is to the left and Greenwich Island has the higher hills on the right. These islands lie towards the Western end of this three hundred mile long chain of islands
Greenwich Island: A five mile channel separates Greenwich Island from Livingston Island
Half Moon Island: Half Moon is a crescent-shaped island that is just over a mile from top to bottom, but it is a two mile walk from the ends of each crescent. We landed at the primary landing site in the South East corner of the crescent

The ship soon had the zodiacs in the water

The South Shetland Islands lie about one hundred miles North of the Antarctic Peninsula: They are still considered as part of Antarctica

An abandoned ship's boat: I've not managed to find confirmation of the age of this boat, but it is generally described as an abandoned whaling-era boat
Practicing the lifeboat launch: It is always reassuring to see the crew practicing a lifeboat launch
It was an easy half mile walk to the tip of the island from the landing site. We were greeting on the beach by the first Chinstrap Penguins and we followed their route to the colony, whilst ensuring we weren't on their main trackway.

There were low numbers of a few other species around the Chinstrap Penguins.
Snowy Sheathbill: This monotypic species breeds on the Antarctic Peninsula, the South Shetlands, South Orkneys & South Georgia. They winter as far North as coastal South-central Chile & East-central Argentina
Snowy Sheathbill: And then there were two
South Polar Skua: There were a few South Polar Skuas around Half Moon Island, but I didn't manage to get any good photos of them. This monotypic subspecies breeds on the South Shetland & South Orkney Islands and coastal Antarctica
Kelp Gull: With only a few hours of darkness each day, sometimes you just need to get some sleep during the daytime
Kelp Gull: This is the austrinus subspecies which breeds on Antarctica & the surrounding Antarctic islands
There was also a Weddell Seal and a Southern Elephant Seal on the island.

It was time to return to the ship
Over lunch, Ortelius repositioned for a second landing at the nearby Yankee Harbour on Greenwich Island. This has a modest Gentoo Penguin colony. I decided to give it a miss as I was still recovering from the ship's cough and the tiredness associated with it. I wanted to be on the bridge as we sailed North out of the South Shetland Islands and like the earlier Kelp Gull, sometimes a power nap during the day helps.
There is long, curved spit which protects Yankee Harbour
Our route, day by day, for the trip
Pippa providing a weather update on our route back to Ushuaia: The pink colours on Windy.com is over two metres of swell, whereas the blue is up to two metres. It looked like we might have a reasonable return crossing of the Drake Passage
The sea conditions were looking good once we were at sea North of the South Shetland Islands: Unfortunately, all I saw was a single Whale blow that evening

5 Dec 25 - Antarctica 25 - Worth Getting Up Early

I had set my alarm for another early start at 04:30. It was well after first light, but having seen an Emperor Penguin, I had allowed myself a lie-in. After a quick cuppa tea, I headed out to find I was the first passenger on the top deck. We were in an area of open water which was just the other side of Rosamel Island. This wasn't surprising given the amount of ice in the Antarctic Sound and the Northern Weddell Sea.
Rosamel Island looked gorgeous in the early morning light
We were in a two mile long area of open water: We were slow cruising around the area
About 05:30, I spotted an Emperor Penguin in the open water. It wasn't close, but it was clearly an Emperor Penguin. Frustratingly, it dived after about forty-five seconds and I failed to relocate it again. It's a shame there weren't others who had got up early, as a few extra pairs of eyes might have helped refind it. Still it was great to have found my own Emperor Penguin.
There were some serious icebergs around
The early morning light provided some atmospheric photos as we moved around the open water
About an hour after seeing the Emperor Penguin, I spotted a pod of four Orca hunting along the edge of the pack ice. They weren't close, but they were surfacing fairly regularly. I was still the only passenger on the top deck, but a small group of Chinese passengers were on the next deck below mine. Fortunately, one spoke reasonable English and he was able to tell his fellow travellers what I had seen. They were pleased to see the Orca. The Orca disappeared after about ten minutes. I suspected they had dived under the ice, before coming up in the edge of the next area of open water.
Orca Type B (Large): I already knew they were Orca based upon my initial views through the bins. On this photo it would have been a bit harder to identify. However, the options are limited to Orca or an Antarctic Minke Whale, once you have ruled out one of the larger Whales. It's unlikely the seas adjacent to Antarctica will be deep enough for a Beaked Whale and there are no Dolphin species around the Antarctic Peninsula
Orca Type B (Large): There is no doubt about the identification when the large male dorsal fin appeared
Orca Type B (Large): This individual appears to have a large white horizontal patch at the front of the body which would indicate it's likely to be a Type B (Large) Orca
The Orca Type B (Large) are also known as Pack Ice Orca. They are large compared to some of the other Orca Ecotypes. Their eye patch is very large and oriented parallel to the body axis. They are more grey-and-white in colouration with a darker grey dorsal cape and pale grey sides. However, after some time in Antarctic waters, they often develop a dirty yellowish appearance caused by a coating of diatoms. It is believed that they undertake rapid, round trip migrations to the tropics, but they spends most of the year in Antarctic waters. The diatoms die off in the warmer waters and the Orca lose their yellowish colouration. They can work as a team to knock Seals off small ice floes, with Weddell Seals being their preferred food. However, they are capable of catching the larger and more powerful Leopard Seals, but there is a higher risk that a Leopard Seal could inflict damage to them before they killed it.
Orca Type B (Large): Finding an Orca pod has been something on my To Do list for a few years, so that was good to have achieved it. I just need to find some in the UK or European waters now
It had been an excellent start to the morning and well worth the early alarm. I went to celebrate when the call to breakfast finally came.
Orca Type B (Large): Soon after this last photo they disappeared
After breakfast, the ship started to push its way through the leads, to see if we could find a way further South. We managed to get a few miles further South, but not enough that would give us any realistic chance of getting close to Snow Hill Island. As we had good visibility and we were unable to get much further South due to the amount of ice, the helicopter pilots, Pippa and the Captain decided that about ten in the morning, the ship would start scenic helicopter flights. The plan for the scenic flights was slightly different to the plan had we been able to visit the Emperor Penguin colony. We would take only twelve passengers in a flight of the three helicopters, which would allow everybody to have a window seat for the twenty minute flight. We had been divided into groups and all the four berth cabin passengers were in the final group to fly. I didn't mind being in the last group, as I wanted to keep looking given the ship hadn't moved more than a few miles from where I had seen the Emperor Penguin and the Orcas. It would have been a different feeling had it been a flight to the Emperor Penguin colony.
We had to push through these patches of broken ice to get to the next area of open water
As we moved around the open water, there was plenty of ice to scan. There was a reasonable selection of interesting subjects to photograph.
An impressive iceberg
Southern Giant Petrel: To identify the two Giant Petrels from each other, you have to see if the bill tip is pastel green or pastel red, which at a distant looks like a pale bill tip or dark tip in Northern Giant Petrel
Southern Giant Petrel: There is clearly no confusion over the identify of this individual
Southern Giant Petrel: It's not often I get photos of this species that are this good
Southern Giant Petrel: About one percent of the Southern Giant Petrels are immediately recognised without having to check the bill tip colouration, as they are the white morph. Northern Giant Petrels do not have a corresponding white morph
Snow Petrel was one of the Seabirds I was most keen to see on my previous Antarctica trip. We saw the first in the Drygalski Fjord in South Georgia and then a few most days in the Drake Passage and Antarctica on my first visit. Similarly, we saw a few as we crossed the Drake Passage and in the Antarctic Sound. But they are a hard species to get a good photo, as I've never seen them very close to the ship.
Snow Petrel: They are a gorgeous Seabird
Snow Petrel: This is the nominate nivea subspecies which breeds on the Antarctic Peninsula & Antarctic islands (except in the Ross Sea region), as well as, South Georgia & Bouvet Island
Snow Petrel: The other subspecies occurs in the Ross Sea region of Antarctica
Snow Petrel: Not as close, but better lit

Unfortunately, the ship had only managed to fly about a third of the flights, before low cloud grounded flying at lunchtime. There was another window in the afternoon, when the visibility improved to allow more flights to depart, before finally more low cloud grounded the flights for the rest of the day. Personally, it wasn't a big problem for me that I didn't get called for my flight, as I didn't think that we would get an ice-free window to allow us to head South towards Snow Hill Island. Therefore, I reckoned there would be plenty of time on the following day for the remaining scenic flights to leave.

It had been a good day, even if we hadn't managed to get any significantly further South during the day. However, with the amount of pack ice between us and Snow Hill Island, we really needed the sea currents and wind to move a lot of the drifting ice to give us a chance to getting clear water to our South. There was one more good Bird seen during the day and I've reserved that for the next Blog Post.
