Las Palmas team

Three more pictures to finish the report of the Coupling Cruise. Below is the Las Palmas team and some of them in Buenos Aires coming back to the real world.

Ushuaia

We finished our cruise in Ushuaia (Argentina) where we stay for a few days before the long fly to our country. Below some pictures of this nice and cold place at the end of the world.

This is the end

This is the end of the cruise. During the last month we were sampling the Bransfield Strait and the Drake Passage but now the Coupling cruise is over. We sailed to Ushuaia (Argentina) with a rather good weather. The sea was in calm but with some swell. Before we enter the Beagle Channel we stop in Puerto Español in order to wait for the Pilots from the Argentinian Army (compulsory to sail through the channel). Now, we are in Ushuaia. Good food, good meat, vegetables (at last) and some drinks to celebrate the happy end. Below some more pictures of the cruise, some ice (of course) and more specimens of the fauna on board.

The featured ice for today

Sailing in the Drake Passage approaching Cape Horn. As it can be observed the sea is almost in calm.

Gone with the wind

Today, after more than three days waiting for the airplane, six members of the Coupling oceanographic cruise leave King George Island to Punta Arenas in Chile. They finished the work here and they will enjoy a salad this night in a restaurant. We will remain here processing samples and sailing through the Bransfield Strait to Elephant Island. Below some more pictures of the Antarctic fauna. No ice for today.

Fed up

Almost 90 oceanographic casts, days of bad weather, calm, wind, snow, freezing,... The sampling is finishing but we will depart with a rather nice picture of the coupling between the physical frame of the Antarctic Peninsula and the flux of carbon promoted by the biota. Finally, our most preciated sampler the Mocness, died two days ago due to a fast electronic shock. We tried to revive it but it was impossible. Fortunately, it happened at the end of sampling. Now, we proceed with the analysis of thousands of samples while we sail again through the Drake, near Elephant Island for some more CTDs and mooring recoveries.

This antarctic pigeon spent a day with us, resting, waking and flying around.

Routine at sea

Now the work is routine. We are sampling and sampling across the Drake. Fortunately, the weather is right, there is no too much wind and the waves are moderate. People are starting to get tired because of the hard work during 24 h, cold weather and boat movement. Those performing experiments are really exhausted because of the difficulty to combine the compulsory watchs and the time to start or finish each experiment. Below some more pictures of the Antarctic researchers on board R.V. Hespérides, and of course, ice...

Our particular jacuzzi at 0 to 1 degrees celsius containing the experiments of Gara Franchy. She is performing dilution experiments to know the grazing of microzooplankton in these waters.

Some krill used for the experiments of Marta Moyano and Inma Herrera. They are measuring respiration, excretion and growth in this keystone species of Antarctica.

Salps, salps and more salps. This is the content of the Mocness nets during all the cruise. These gelatinous organisms showed large patches and appeared in almost all the tows performed.

Rendezvous in the Southern Ocean

Yesterday we met the vessel Las Palmas which is the boat servicing the Spanish Antarctic Bases. They had some problems with the engines and they spent about three weeks in Punta Arenas. Our rendezvous was in the Drake, in the area we are working.

Who is the photographer?

The cruise leader. The white hair is not because of the calendar. It is snow.

Snow in the Antarctic Sound

Heavy snow in the middle of the Antarctic Sound. The scientists had to work in very cold conditions but happy to feel the snow on their faces. This was our last work on the Antarctic Sound. Now we are in the Drake Passage again, sampling to the north of South Shetland Islands. The wind is in calm but the swell is quite high. Last night was almost impossible to work. This morning we had to stop due to another problem with the Mocness net. Now, it is repaired but we are afraid of new damages. Below some more pictures of the fauna on board and, of course, some more ice.

Freezing in the Antarctic Sound

Very, very low temperatures in the Antarctic Sound. To work outside here is really hard and the turbomap and Mocness teams knows the feeling. Today some pictures to show the freezing temperatures and the turbomap team at work. They have to stay for an hour an half outside, suffering the very cold wind.
